8 1 Introduction This manual describes how to work with the Excel spreadsheet FFPLAN.xls which enables the SAP Technical Consultant to enter all the necessary configuration data for a customer-specific FlexFrame environment on a Windows PC during the preparation phase and to create the configuration files and the network cabling plan. Please try to avoid using the FlexFrame Tool with having other Excel sheets open at the same time. Closing and saving can cause damages in these files. After the data has been entered it is checked for plausibility using the Check data & generate config files button (see page 12). If all the data has been entered correctly, it is stored in the following configuration files: ff_cn.conf ff_an.conf ff_services.conf ff_misc.conf The configuration files are stored on an external data medium (e.g. a USB stick) and later read in by the installation scripts during the initial installation of the FlexFrame Control Nodes. All the required FlexFrame configurations are implemented automatically using this configuration data. Among other things, the configuration files contain information on the: network switch configuration hosts services network boot parameters LDAP parameters DHCP parameters automounter parameters for file systems user and group parameters FlexFrame pool and group definitions SAP services database systems After the configuration files have been created, the network cabling plan is generated with a Perl script (ff_wiring.pl) on a LINUX based system where a PERL runtime environment is available.

10 2 Network Concept The network concept of FlexFrame is very essential. We will therefore first provide a brief explanation of this concept. If you are already familiar with it, please continue with chapter Working with the Excel Spreadsheet on page 7. The network is the backbone of the FlexFrame solution. Communication between the various nodes is done exclusively over the IP network infrastructure. This is used both for communication between server(s) and client(s) and for delivering IO data blocks from the NAS (Network Attached Storage) to the server. The IP network infrastructure is essential for every FlexFrame configuration. FlexFrame is designed with a dedicated network for connections between server and storage that is reserved for FlexFrame traffic only. Only one network segment, the Client VLAN (see section VLAN Segments on page 4), is routed outside the FlexFrame network to connect to the existing outside network. The FlexFrame internal physical network configuration is fully redundant to ensure high availability. Based on this physical network, a number of virtual network segments are configured. One virtual LAN (VLAN) is used for FlexFrame infrastructure management and is called the Control LAN. Three further VLANs, the Client LAN, the Server LAN and the Storage LAN, are added for each pool. A pool is a group of Application Nodes in a FlexFrame environment that belong to the same customer. A pool is usually related to a client. By assigning separate VLANs to every pool these clients are well separated. This multi client capability of FlexFrame is an essential feature. 2.1 LAN Failover LAN failover describes the ability of the FlexFrame environment to use a logical network interface that consists of several physical network interface cards (NICs), which in turn use redundant network paths (cables and switches). When a network component (NIC, cable, switch, etc.) fails, the network management logic will switch-over to another network interface card and path. 2.2 LAN Trunking High demands on network throughput the network path to the NAS system may require a bandwidth of more than a single NIC. LAN Trunking (IEEE 802.1q) allows multiple paths to the network backbone to be combined. The method applied is able to work with the coexisting LAN failover solution described above. It is also required that the load balancing uses the round-robin method based on Ethernet packages. Planning Tool 3

11 Network Concept 2.3 VLAN Segments FlexFrame relies on a virtual network concept, providing higher availability as well as increased flexibility for the FlexFrame environment. This concept relies on VLAN technology that allows multiple virtual networks to be run across a single network wiring system. Additionally, in order to ensure high network availability, LAN bonding is used on every node. This includes a double switch and wiring infrastructure, to keep the whole environment working, even when a network switch, cable or NIC fails. Furthermore, the network segments are prioritized to ensure that important connections are preferred. Similar to former FlexFrame versions, typically four networks are used within one Flex- Frame system or within a single FlexFrame pool. FlexFrame uses virtual network segments. These virtual networks run through redundant NICs, using bonding on Linux and IPMP on Solaris. The figure below outlines the basic network segments of a typical FlexFrame environment with Linux-based Application Nodes.

12 Network Concept The following virtual network segments are mandatory for FlexFrame: Client VLAN (one for each pool) The purpose of the Client VLAN segment is to provide dedicated user connectivity to the SAP instances. This segment also allows administrators to access the Control Nodes. Control VLAN (one for all pools together) The Control VLAN segment carries all administrative communication for Remote View Service Board (RSB) and / or IPMI-Interfaces. Control LAN access to the Application Nodes is required for monitoring board (RSB) intervention. It may be redundant (doubled), depending on the server type (e.g. PRIMERGY BX300). Server VLAN (one for each pool) The Server VLAN segment is used for SAP instances to communicate with each other and with the databases. Storage VLAN (one for each pool) The Storage VLAN segment is dedicated to NFS communication for accessing the executables of SAP and the RDBMS, as well as the IO of the database content and SAP instances. The network bandwidth has to be at least one Gbit/sec for all components to handle intense data traffic. 2.4 Switches Network switching components play a very important role within FlexFrame. Therefore, only the following switches are tested and supported: Cisco Catalyst 3750G This switch family supports VLAN technology for a flexible configuration of the various network segments and QoS (Quality of Service) to prioritize traffic (e.g. higher priority for production systems over test systems etc.). The Cisco StackWise Technology is able to use cross-stack LAN trunking (this means the usage of ports of different switches within one stack). Planning Tool 5

14 3 Working with the Excel Spreadsheet The spreadsheet comprises a number of forms which are described in the order in which they are generally processed. These forms contain input fields (yellow background) output fields (green or white background) buttons (gray background) that open dialog boxes to enter parameters If you click on the OK button in a dialog box, a semantics check and plausibility check of the parameter values is performed. If errors are detected, a message is shown and the dialog box remains open so that the incorrect entries can be corrected. In this manual, fields which permit entries are written in italics. Before you begin working with the Excel spreadsheet, you should create a backup copy of the original Excel file. As the workbook initially contains an example, the existing table contents must be deleted for a concrete configuration. This is done using the Start new button in the General Information form (see page 10). The spreadsheet only works correctly if Excel macros are activated. Excel functions (such as manual execution of functions) and foreign macros should not be used, otherwise errors can occur in the functionality. The functionality of the spreadsheet can be seriously damaged, by using functions like cut and paste. Don t use this functionality, because errors caused by using cut and paste are not visible directly. The generated files can contain incorrect data under these circumstances. 3.1 Requirements This document is only to be used by SAP Technical Consultants who have successfully completed FlexFrame, PRIMECLUSTER and Network Appliance Filer training. They should also have expert knowledge of Linux OS and Solaris OS. SAP system installations should only be performed by consultants who are certified for your operating system, your database, and the SAP system you are installing. Planning Tool 7

The name must start with a letter and may only contain numbers, letters and -. The pool name becomes part of an automatically generated host name that may only be up to 13 characters long in an SAP environment. Therefore, we recommend that the pool name should be limited to three characters and written in lower case letters. The name for the first group of the first pool has to be specified in this field. The name must start with a letter and may only contain numbers, letters and _ or -. The relevant network has to be specified in IPv4 format (e.g ) in this field. In binary, the network address must contain a zero at the same position as the netmask of the individual LAN segments. The individual networks must be different from each other. The relevant netmask has to be specified in IPv4 format (e.g ) in this field. In the network section the netmask must consist of binary ones, and in the host section of binary zeros. You are recommended to use the same netmask for all network segments. The relevant VLAN ID has to be specified in this field. The VLAN ID is an integer between 2 and The VLAN IDs must be unique over all LAN segments. The associated Control Node type has to be selected in this pick list.

19 General Information Form 4.2 Check data & generate config files Button After all the data has been entered in the forms described below, this button is used to open the Generate Configuration Files dialog box where you can specify the path names for the configuration files to be created. Figure 5: Generate Configuration Files Dialog Box Check routines are called using the OK button. If these check routines do not report an error, the configuration files are generated automatically. If there are errors, these are displayed in the Checking results display field and can be exported to a log file (text file) by clicking on the Generate result Log button. This information can then be used to correct the errors in the forms. Under Saving to you can use the... button to select the path where the configuration files and the log file are to be saved. The configuration files may not be modified by applications of third-party suppliers (e.g. MS Word ) as this might cause the installation procedure and subsequent functions to fail. All the generated files belong together and may only be processed further or forwarded as a unit. The overall configuration can be printed out for documentation purposes using the Print all sheets button. All prints contain a hint that no corresponding configuration files where generated with the print. The time stamp of the files can be found in the header of every print out. This button is only enabled, if generating of the files is successful. 12, Planning Tool

20 5 Pools Form In this form, the features for a pool are defined. A pool is a group of Application Nodes in a FlexFrame environment which belong to the same customer. This is, for example, the customer of a service provider who has a number of systems made available to him/her to use exclusively. A pool contains multiple systems and is separated and protected from other pools by different network addresses and access controls. Servers within a group can take over services. Pools are of central importance and have to be defined first. For example, the pool name is used as a selection criterion in the Controlling, Application Nodes, SAP Services and External Connectivity forms (e.g. for calculating the client IPs). Figure 6: Pools Form (left half) Figure 7: Pools Form (right half) The current parameters of the pools which already exist are displayed in the form s output fields. Planning Tool 13

21 Pools Form 5.1 Add new pool Button This button opens the Enter New Pool dialog box in which the parameters for a new pool in the FlexFrame configuration are specified. If the parameters of an existing pool are to be modified, this pool must first be deleted using the Delete selected pool button (see page 15) and then be recreated using Add new pool. Figure 8: Enter New Pool Dialog Box Input fields Name Enter new pool name Enter group name Description The name of the new pool has to be specified in this field.the name must start with a letter and may only contain numbers, letters and -. As the pool name becomes part of an automatically generated host name and host names may only be up to 13 characters long in the SAP environment, we recommend that the pool name should be limited to three characters and written in lower case letters. The name for the first group of the new pool has to be specified in this field. The name must start with a letter and may only contain numbers, letters and _ or -. 14, Planning Tool

In binary terms the network must contain a zero at the same position in the individual LAN segments as the associated netmask. The individual networks must be different. The relevant netmask has to be specified in IPv4 format (e.g ) in this field. In the network section the netmask must consist of binary ones, and in the host section of binary zeros. You are recommended to use the same netmask for all network segments. The relevant VLAN ID has to be specified in this field. The VLAN ID is an integer between 2 and The VLAN IDs have to be unambiguous over all LAN segments. The associated first Filer of the new pool has to be selected in this pick list (only existing Filer from Filer Details are shown). The DNS domain name has to be specified in this field (alphanumeric,. and - is allowed - e.g. dns1.fsc.com) - no more checks available. The information on the Control LAN is taken over from the first pool. If the pool shall be equipped with Application Nodes of type BX600 (blade server in a blade server cabinet with switch blades of type Quanta, see Application Node Form), then the following restriction concerning the VLAN-ID has to be considered: Quanta switch blades only allow the VLAN ID range from 1 to 3965! 5.2 Delete selected pool Button The pool selected in the form can be deleted using this button. After a security prompt the selected pool and all associated components in the other forms are deleted. Exceptions: If this pool was entered in the Application Nodes form, the pool is not deleted. To prevent inconsistencies, the corresponding entries Application Nodes must be edited first. The first pool cannot be deleted. If this is necessary, it can only be done using the Start new button (see page 10). Planning Tool 15

24 6 Pool Group Form The pool groups are managed in this form. A pool group is an additional grouping level within a pool. All Application Nodes with the same characteristics are included in a pool group, e.g. servers with the same operating systems or performance classes. At least one spare Application Node is expected per pool group. The internal check routines verify the existence of at least two Application Nodes. The parameters of this form are required only for Application Nodes. As each pool must contain at least one pool group, a pool group is automatically created for each new pool. Figure 9: Pool Group Form The existing pools and their groups are displayed in the output fields of the form. Planning Tool 17

25 Pool Group Form 6.1 Add new group Button This button opens the Add Pool Group dialog box where a new pool group can be created.

30 8 Pool Specific UID and GID Form This form is used to manage user ids and group ids for all users and groups that might be necessary when installing and running the SAP services in the given pool. During installation the UID or GIDs given here are only used, when a SAP version or DB version that makes use of this user or group is actually installed. If there is no UID or GID given here for a user or a group actually needed for a SAP or DB installation, then a default value will be used. When migrating an existing SAP Installation to FlexFrame the existing UID and GIDs should be used in this form. Figure 14: Pool specific UID and GID Form 8.1 Add UIDs GIDs Button This button opens the Add Pool UIDs GIDs dialog box where you can enter a pool specific user ID for the user sdb, as well as a pool specific group ID for each of the the groups sapsys, dba, oper, sdba, and sapinst. If you do not enter a value in one of these fields, a default value will be used during installation. The installation manual gives you further information about the default values used.

32 9 Controlling Form This form is used to manage central, jointly used infrastructure components of a Flex- Frame environment such as the network, switches and Control Nodes (as central monitoring instance), and also the memory subsystem which, if required, is addressed via different networks (see also the Pools form on page 12). Figure 16: Controlling Form (left half) Figure 17: Controlling Form (right half) Planning Tool 25

33 Controlling Form Input/output fields Name Controlling/Shared Equipment Host name Description General host name which is required to form the host names of the individual LAN segments. In SAP environments host names are currently limited to 13 alpha numeric characters including the hyphen ( - ). The first character must be a letter. In an SAP environment host names are case-sensitive. Type Display of the type of component inserted. HW ID Display of the HW ID of component inserted (will be created automatically and can only be changed for Filer). Switch Group LAN Section Host Display of the related switch group of component inserted (can be changed if defined by administrator). An IPv4 address consists of the two parts; network and host. With its 1 bits, the netmask defines the network part and its 0 bits at the end define the host part. The network numbers for the individual segments have been specified before when the pool was entered. The host part is entered for each individual component here, e.g. (the host part of the IP address is underlined): Netmask: > Host IP: Netmask: > Host IP: LAN Section Pool Display of the associated pool. In the other output fields the host names, IP addresses and interfaces of the Client LANs, Storage LANs, Server LANs and Control LANs are displayed. In the current release of the spreadsheet, the Interface fields are used for documentation purposes only and are not written to the configuration files. Therefore, the settings can be different in the actual configuration. This is not an error. 26, Planning Tool

34 Controlling Form On the Control Nodes the interface name in the Control LAN is bond0 or RSB. The interface name in the other VLANs it is derived from vlan extended by the VLAN ID. In the case of all other components no interface names are formed, while the IP addresses are generated. All IP addresses are derived from the pool s network IP and the specified host number, taking the netmask into account. All new physical Filer systems have to be defined in the NAS Configuration Details form first! 9.1 Edit host part of selected IP Button For a description how to assign an individual host part to the the IP addresses see the corresponding description in the Application Nodes form (see page 49). 9.2 Add new Button This button opens the Add Controlling Component dialog box where a controlling component can be added. Only entries of the type Filer, Switch Group and Remote Console Adapter (RCA) can be added. Figure 18: Add Controlling Component Dialog Box Input fields Name Select pool Select type Description The associated pool has to be selected in this pick list. The controlling component to be added has to be selected in this pick list. 9.3 Delete selected Button You can use this button to delete the selected controlling component of the type Filer, Switch Group or Remote Console Adapter. The last Filer of a pool can not be deleted. Planning Tool 27

35 Controlling Form 9.4 Change HW ID Button This button opens the Change HW ID dialog box where the hardware ID of the selected Filer can be changed. Only entries of the type Filer can be changed. A single hardware ID can be used only once in a pool. To add new hardware IDs see NAS Configuration Details form. Figure 19: Change HW ID Dialog Box Input field Name HW ID Description The associated hardware ID has to be selected in this pick list. Only entries of the NAS Configuration Details form are shown. 9.5 Change switch group Button This button opens Change Switch Group dialog box where the associated switch group of the selected item can be changed. The switch group of only a few item types can be changed (defined by the administrator). Figure 20: Change Switch Group Dialog Box Input field Name Select SWG Description The associated switch group has to be selected in this pick list. 28, Planning Tool

36 10 NAS Configuration Details Form This form is used to manage all physical Filer systems. Figure 21: NAS Configuration Details Form Input/output fields Name HW ID Filer name Host Description Display of the hardware ID (automatically generated). General host name which is required to form the host names of the individual LAN segments. In SAP environments currently host names are limited to 13 alpha numeric characters including the hyphen ( - ). The first character must be a letter. In the SAP environment host names are casesensitive. For Filer names only lower case letters should be used because upper case letters will result in serious problems when applying administration commands later. An IPv4 address consists of the two parts; network and host. With its 1 bits, the netmask defines the network part and its 0 bits at the end define the host part. The network numbers for the individual segments have been specified before when the pool was entered. The host part is entered for each individual component here, e.g. (the host part of the IP address is underlined): Netmask: > Host IP: Netmask: > Host IP: Filer type Display of the Filer type to be used. # NICs Display of the hardware ID of components inserted (will be created automatically and can only be changed for Filer). Switch Group Display of the switch group for the component inserted (can be changed if defined by the administrator). Planning Tool 29

37 NAS Configuration Details Form Name Cluster partner / NS-Type: Grp ID Description For EMC NAS systems (Filer type: NS-Type) this field shows a group ID which identifies with the same group ID all data movers of a EMC NAS system that belong together. The group ID is gene-rated by the the planning tool. For other NAS (Netapp filers) systems the field displays the hardware ID of the cluster partner ( 0 if no cluster partner exists). The remaining output fields display the host names, IP addresses and interfaces in the Control LAN. With the current state of the spreadsheet, the interface field is used for documentational purposes only and can be different in the actual application. This is not an error Definition of an EMC NAS System Every data mover (active and standby) of a EMC NAS system has an entry in the NAS Configuration Details form in form of a row. You add an EMC NAS system by choosing an NS-Type filer in the Add new dialog of this form and enter the number of data movers. The automatically generated NS-Type Grp Id in the related column groups data movers for one EMC NAS system together. For every data mover a control LAN IP has to be defined. If there are more data movers than control stations you will have control LAN IPs that are obsolete. In the Controlling form you have to define a storage LAN IP for every active data mover of a Celera. Data movers of a EMC NAS system without any storage LAN IP will be considered as standby data movers. In the External Connectivity form you are able to define any other control LAN address needed, e.g. Storage Processor or FC Switch. The control LAN addresses defined here will have a switch port reserved for access to this LAN. For further details see the Switch Groups and External Connectivity forms EMC NAS Naming Conventions in the Wiring Plan The name of the first data mover in the field Filer name of the NAS Configuration Details form (see Figure 22) is of special interest. The first data mover name is also the name that identifies the complete EMC NAS system. By this name, in our example cel1-dm1, the EMC NAS system will also be identified in the wiring plan as well as later, when administrating a FlexFrame, this will be the name to access this EMC NAS system. An EMC NAS system assigns to its data movers default names. The control station is called server_1, the first data mover is called server_2, the second data mover is called server_3 and so on. These default names of an EMC NAS system usually are not changed. In the wiring plan (see Figure 23) you will also find for your convenience the 30, Planning Tool

38 NAS Configuration Details Form data mover names from the NAS Configuration Details form next to the default names of the EMC NAS system. Furthermore for the convenience of the PlanningTool user the data mover names can be used in the PlanningTool as you would use the names of NetApp filers, which means you can assign in the Controlling form to every data mover a set of Storage Lan addresses. For every pool that accesses data on this data mover one address. As already earlier mentioned a data mover with no Storage Lan address will be considered a standby data mover.

44 12 Switch Groups Form In this form the switch types actually used are assigned to the switch groups. The switch groups themselves can be defined in the Controlling form (see page 25). A switch group is typically used as a network unit for the redundant connection of the hosts for each system cabinet (19 rack). This is intended to reduce the cabling outside the system cabinet to a minimum. Figure 29: Switch Groups Form During configuration only lines that contain entries in the Switch Type field are taken into account. Planning Tool 37

45 Switch Groups Form Input/output fields Name Distribute corporate LAN ports to different switch groups Use Fiber Optic port to corporate LAN Separate VLANs to corporate LAN Port count of switch group interconnects Group Type Switch Type Description When X is set, the corporate network cabeling is connected to the switches of the first two switch groups. When X is not set the corporate network is connected to the switches of the first switch group only. When X is set, the fibre optic ports of the switches are used for the connection to the corporate network if possible (among those connections is the client network for the SAP users). If multiple pools are used, multiple Client VLANs must be connected to the corporate network. This option allows you to select whether one (for all VLANs common) corporate network port is to be provided for all Client LANs (X not set) or if ports (X set) are provided for each Client VLAN. Number of ports that are provided for the switch group interconnect. Display of the switch group name as assigned in the Controlling form. Display of the type of switch group (for documentation purpose only). Display of the switch type of each switch within the group (required for the cabling and the switch configuration). Knowledge of the precise name of each switch type is required to create the cabling plan and the switch configurations. At least two switches have to be configured in each switch group to provide network redundancy. The upper limit is currently eight switches. To select a switch the cursor has to be positioned to the relevant line in the form and the switch type required has to be selected and modified using the Change selected switch type button. The switches within a group are connected in such a way that the hosts are connected with redundancy. The first two switches of a group are connected redundantly with the neighboring switch groups across switch group boundaries. Connecting switch groups to each other is in the responsibility of the customer. FlexFrame only provides uplink ports at the switch groups. Only two switch groups my be connected directly. 38, Planning Tool

48 13 External Connectivity Form The network connections of the internal FlexFrame networks to the operator s corporate network are defined in this form. Entries in the various LAN segments may, for example, be necessary for backup servers or servers outside the FlexFrame environment. With the Planning Tool a so called External Connectivity can be planned. It leads to configuration of switch ports. The external connectivity switch ports are currently configured as untagged VLAN switch ports in case of a single VLAN. In case of multiple VLANs, all will be configured as tagged. Devices plugged into these ports require interfaces using tagged VLANs. To be able to communicate, these VLANs have to be configured with the same VLAN IDs like the switch port and as configured with the Planning Tool. For reasons of redundancy, two switch ports are configured for each externally connected device. If the redundancy has to be used on the device side too, a similar active-backup failover configuration like on the Control and Application Nodes has to be used. A link aggregation for load balancing will not work and may block the entire network! The saprouter that may run on the Control Node for the first pool as part of PRIMECLUSTER has its own IP address. Therefore an entry for the saprouter should be given here (type Other). The host name saprouterint is reserved for that purpose and has to be entered for the Client LAN. In this case no entries are required for the Storage or Server LAN. The host name (and at least one host name in the Client, Storage, Server LAN or Control LAN) has to be entered in each line.

52 14 Application Nodes Form In this form you manage the Application Nodes of the FlexFrame environment on which the SAP services run. Depending on the type of Application Node, one or more lines are inserted. This is particularly important for Blade servers with a chassis as they use common resources (Management Blade and Switch Blades) that need to be configured once only per Blade chassis. All host names generated on this spreadsheet are used by FlexFrame system software. These host names are physical host names and may not be used by SAP applications. Host names for Application Nodes are generated automatically by this spreadsheet. Host names are differentiated by a suffix to permit an Application Node to be addressed via a selected VLAN segment. For the Storage VLAN this suffix is st, for the Server VLAN it is se, for the Control VLAN it is co, and for the Client VLAN no suffix is used. These host names are not restricted by SAP conventions like virtual host names (For virtual host names see also chapter SAP Services form on page 53). To provide network redundancy for PRIMEPOWER nodes with Solaris IPMP, additional test addresses are required. When they are created, these entries are added automatically as the types Solaris HA1 and Solaris HA2. Figure 36: Application Nodes Form (left half) Planning Tool 45

53 Application Nodes Form Figure 37: Application Nodes Form (right half) Input/output fields Name Description Application Nodes Host name General host name which is required to generate the host names in the individual VLAN segments. In SAP environments currently host names are limited to 13 alpha numeric characters including the hyphen ( - ). The first character must be a letter. In the SAP environment host names are case-sensitive. Type Auto No Switch Group OS Display of the type of component added.

57 Application Nodes Form 14.6 Edit host part of selected IP Button This button opens the Edit IP Host Part dialog box. Usually the Planning Tool generates IP addresses for its components from the given network addresses for each of the available LANs and a common host part. Since there is only one Control LAN for all components and because of the mapping of Control LAN on one side and Client, Server and Storage LAN addresses on the other side, it is possible to run into problems defining all of the Control LAN addresses needed. More flexible definition of IP addresses you can achieve, when you select the generated IP addresses you want to assign an individual host part to and press the button Edit IP Host Part. A dialog box opens that allows you to enter the new host part of the first of the selected IP addresses in the column. The new value is auto incremented and assigned to all selected IP addresses in sequence. When the host part of an IP address spans across byte boundery this is not respected by the auto incrementation algorithm. Editing across byte boundery is not possible. In this case you have to edit the IP addresses column in two steps. Figure 42: Edit IP Host Part Dialog Box Input/output field/button Name Old Value New Value Reset to common host part Description Current host part of the first of the selected IP addresses. New host part of the first of the selected IP addresses. The host part is reset to the value as it is defined in the column Host of the form.

60 15 SAP Services Form All the SAP systems and their instances for a FlexFrame environment are entered in this form. The virtual host name and its corresponding virtual IP address are used by applications to address the server on which an SAP instance is running. This virtual IP address is assigned to a physical host dynamically before an SAP instance is started. The virtual IP address thus identifies the actual host on which the SAP instance is running on. If an SAP instance is moved to another server, this SAP instance is always addressable using the same virtual IP address. Virtual host IP addresses are also used for communication from applications outside FlexFrame systems, i.e. SAP front ends such as SAPGUI. Virtual host names and virtual IP addresses are generated automatically by the planning tool. Formation Rules for Virtual Host Names The virtual host name is formed by the service type, the two-digit instance number for the service type app and the SID: <service type>[<id>]<sid>[<-lan type>] where <service type> can be one of: db - database instance ci - central instance (ABAP) app - application instance (ABAP) ascs - ABAP SAP central services instance scs - JAVA SAP central services instance jc - JAVA central instance j - JAVA application instance lc - LiveCache instance ers - Enqueue Replication Service instance <ID> is an instance number from 00 to 96 (except 2, 25, 43, 72 and 89) for the service types. The instance number is unique in the SAP system scope. It is left empty for db and lc service types. <SID> is the system ID of an SAP system. <LAN type> -se Server LAN empty string Client LAN This host name formation rule for virtual services is mandatory in version 3.2 of the Flex- Frame solution. Some components rely on this rule. Planning Tool 53

61 SAP Services Form In a FlexFrame environment, each node name must be unique. However, each node may have multiple host names that are derived from the node name using a defined naming rule. In the SAP environment, host names are currently limited to 13 alphanumeric characters including the hyphen ( - ). The first character must be a letter. In the SAP environment host names are case-sensitive (see SAP Note No ). Figure 45: SAP Services Form (left half) Figure 46: SAP Services Form (right half) 54, Planning Tool
