7 2 Raidtec Manager TM RAID Management Software Overview The Raidtec Manager Management Software is an OS independent Java Application that manages the Raidtec FS3102 system via an Ethernet connection. The software should be installed on the host system that the administrator will use to manage the system. This software is provided on a CD that is shipped with the Raidtec FS3102 system. The Raidtec Manager Management Software uses a memory resident database to store configuration and alert data during operation. This data is periodically saved in the Raidtec Manager directory on the host system. 2.1 Installation The CD should autoload when put in a CD drive. If it does not autoload, open the CD and start the file install.htm. This will bring up the following page (Figure 2-1 Initial Raidtec Manager Screen) on the browser. Select Start Installer for Windows to install the software. Figure 2-1 Initial Raidtec Manager Screen Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 7 of 109

8 2.2 Application Start Up After the installation has completed, run Raidtec Manager from the Windows Start Menu. The first screen displayed allows the administrator to find all Raidtec FS3102 system(s) that are on the network. By default, this utility will search the primary subnet that the host computer is connected to. If the system is on a different subnet, then the administrator will need to change the IP address search range by clicking on the Advanced link, (see Figure 2-2. The subnet must be visible to the administration computer. If the IP address is known, it may be entered manually by clicking on the Manual button. NOTE: If the computer that has Raidtec Manager installed has more than one IP address, the administrator may need to manually enter the IP address range to search over. Figure 2-2: Detect Systems Screen The following table gives an explanation of each screen section. FIELD Search Cancel Search Manual Systems Found Advanced DESCRIPTION The administrator selects this to search for all Raidtec CS3102 and FS3102 systems on the network. Cancels a search that is in progress. The administrator can select manual to manually enter the IP Address. After a search on the network is performed, all Raidtec CS3102 and FS3102 systems found on the network will be listed here. The administrator can double click on an entry to connect to the system. Selecting advanced allows the administrator to change the IP address range to search. It also allows the administrator to put Raidtec Manager into a demo mode. Table 2-1 Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 8 of 109

9 2.2.1 Default IP Address By default, the FS3102 is configured to use DHCP. If no IP address has been previously assigned and DHCP is not enabled, the Raidtec FS3102 system will use a factory default IP address located on the cover of the Quick Start Guide. The default IP address is intended for temporary use only. If DHCP is not being used, it is strongly recommended that the IP address be changed to a permanent address on the local subnet. Note: To connect to the system using the default IP address, it is necessary to configure the network adaptor on the administration computer to the same subnet as the FS3102. After connecting to the FS3102, the IP address may be changed using the options provided in Raidtec Manager > Administration > IP Connection. After changing the IP address, the FS3102 should be power cycled to activate the new IP address and the administration computer should be reconfigured to the new subnet. Raidtec Manager should also be closed and restarted to search for the new IP address of the system Advanced Settings The Advanced screen allows the administrator to change the IP address range to search over. Figure 2-3 shows the Advanced screen. Figure 2-3: Advanced Screen Other Settings If the administrator is still having problems detecting the system they may have encountered one of the following: - The proxy configuration of Raidtec Manager may be incorrect. Refer to Connections Settings, section for more information. Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 9 of 109

10 - The connection is being made through a firewall and the firewall has redirected port 80 to a different port. In this case connect manually and insert :<port_id> in the system field, e.g : Connecting to Raidtec Manager After the administrator selects a system from the Search screen or has entered the IP address of the system in the Manual screen, the administrator must enter the password for the system. The default password is admin. If this is the first time the administrator has connected to this system using Raidtec Manager, the setup wizard will be displayed (see section 2.4) The wizard guides the administrator through the process of setting up the configuration of the system. If the default password is entered, the system will go to the Change Password screen (see section 6.4) in the Administration menu before continuing. Figure 2-4 shows the Enter Password screen. Figure 2-4: Enter Password Screen The following table gives an explanation of each screen section. FIELD System Username Password Previous Connect DESCRIPTION The list of systems that have been detected by Raidtec Manager. The name of the user connecting to the system. There will always be a user admin on the system. The administrator may also have setup a guest user. The administrator enters the password to log in to the system. The default password is admin. Returns to the Detect Systems screen. Connects to the selected system. Table 2-2 NOTE: The password can be reset to admin via the serial port (see the Interface Reference Guide). The password is also reset to admin if the reset button on the controller is pressed and held while the system is being powered up. This also restores the default IP address (see the Interface Reference Guide). Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 10 of 109

11 2.4 Setup Wizard The Raidtec FS3102 system is shipped with a default configuration. When it arrives at the customer site the administrator will have to update the configuration. The setup wizard guides the administrator through the following steps in the process: - Welcome Screen - Change Password - IP Connection - Notification Setup - Next Steps The setup wizard will run every time it detects a new system that it has not previously connected to Setup Wizard - Welcome Screen The Welcome screen is shown in Figure 2-5. It gives a summary of the steps that the wizard will perform Setup Wizard - Change Password Screen Figure 2-5: Setup Wizard - Welcome Screen The Change Password screen is shown in Figure 2-6. This screen is used to change the password used to log into the system. It is also possible to setup a guest user, which has read access to the system. Note: The name of the administrator user is admin. This cannot be changed. The default password for the Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 11 of 109

15 FIELD System Name Use DHCP MAC Address IP Address NetMask Primary DNS Alternate DNS Gateway IP Address Domain Back Next DESCRIPTION The user-friendly name of the system. This name will be displayed when the system is detected in the open connection screen when a search is completed. NOTE: This name will not be resolved using DNS name resolution. If DHCP is enabled on the network it is recommended that it be used to dynamically assign the IP address. If disabled is selected the administrator should enter the static IP configuration in the fields below. The hardware address of the controller. The IP address assigned to the system. Alerts will be sent from this IP address. This is also the IP address that Raidtec Manager will use when connecting. This is a 32 bit mask that shows how an internet address is divided on the network. This value should be set to the current settings of the network. The IP Address of the DNS Server that the system uses to resolve host names. At least one IP Address is required if DNS is to be used for name resolution. This is required to be set up if a host name is entered in the Server Address field in the Notification Setup screen. The alternate DNS server to use for name resolution if the primary server is unavailable. The IP address which enables communication between computer networks, which may (or may not) use different protocols. This value should be set to the current settings of the network. If the Gateway IP address is not set correctly, Raidtec Manager will encounter problems connecting to the system through a firewall. The domain name of the organisation where the system resides. Go back to the Password screen. Save the settings on the current screen and continue to the next screen. NOTE: All systems will be configured with DHCP enabled by default. If the network is setup with a DHCP server, the IP address should be automatically detected when connecting to the network Setup Wizard - Notification Setup Screen The Notification Setup Screen is shown in Figure 2-8. This screen allows the administrator to set up the alert notification for the system. The administrator can have alerts sent to a mobile phone or other SMS compatible device by using a third party product that converts the SMTP messages to SMS and then redirects them to the SMS compatible device. If this is used, the SMTP messages should be sent to the address provided by the third party provider. Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 15 of 109

29 FIELD RAID Name RAID Profile RAID Level RAID Serial Number Write Cache Read Cache Read Ahead Auto Rebuild Hot Spare Strategy Capacity (GB) State Progress Table View Show Disk Info DESCRIPTION User-friendly name, which helps the administrator identify the RAID. This is selected when the RAID is created. The RAID Profile defines the general operating or application environment in which the RAID will be used (e.g. one RAID volume might be optimised for database applications while another might be optimised for file server applications). The RAID profile cannot be modified. The level of the RAID, selected when the RAID is created. The current options available are RAID levels 0, 1, 5 and 10. A RAID 10 will be displayed as a RAID 1. The serial number of the RAID is a unique hexadecimal number assigned to the RAID. The controller assigns this during the creation of the RAID. If enabled, the controller will respond with Good status when the data is written to the cache. If enabled, the controller will store the data most recently retrieved in the cache. If enabled, the controller will read ahead to optimize performance on sequential reads. If a RAID becomes degraded (i.e. a disk fails) it can be automatically rebuilt if a spare is available. This option can either be disabled, ASAP or background. If this option is disabled then an administrator has to initiate the rebuild. If it is set to background then the rebuild takes a lower priority than normal operations that occur on the system. If it is set to ASAP, then the rebuild will be done as quickly as possible while still allowing reading and writing. The Auto Rebuild option is not available for RAID level 0. NOTE: The performance of the system will slow down during a rebuild. NOTE: When rebuilding a RAID the administrator should not remove the faulty disk until the rebuild is complete. If the administrator has to remove the disk the data should be backed up. NOTE: The priority set in this field is also used when initializing and verifying the RAID. If auto rebuild is set to disabled then the RAID will be initialized/verified at the highest priority. The sparing strategies available are global, local or none. If global is selected then the spare disk can be used to rebuild any RAID on the system. If local is selected then the spare disk can only be used to rebuild the selected RAID. If the hot spare strategy is none then there is no disk reserved on the system that the RAID can rebuild onto in the event of a disk failure. Capacity of the RAID in GB (Gigabytes). The states available are: Good Degraded Rebuilding Initializing Expanding Verifying Inaccessible Visual indicator for progress on RAID initialization, expansion or verification. Takes the administrator to the Select RAID from Table screen, which displays a summary of all RAIDs on the system. Takes the administrator to the Disk Information screen, which displays the disks that are part of the selected RAID and their location in the system. Table Disk Information Figure 3-3 displays the Disk Information screen. This displays the disks that are part of the RAID. The administrator can select a RAID from the RAID tree by selecting the RAID name to view the status of the selected RAID. This is a read only screen. The RAID cannot be modified from this screen.

31 FIELD RAID Disk Information RAID Disks Disabled slot icon Disk missing from RAID Selected Disk Information Table View Show RAID Info DESCRIPTION This gives a display of the disks that are part of the RAID and their location in the system. A disk icon is displayed in each slot that contains a disk that is part of the RAID that is selected in the RAID tree. A slot is shown as null (disabled) if there is no drive present or if the drive is not a member of the currently selected RAID set. If a disk that is part of a RAID is no longer available, the serial number of the missing disk will be displayed. If the last known location in the enclosure is still available, the serial number of the missing disk will be shown in that location. This message will be displayed if: The disk has become faulty or The backplane in the enclosure is faulty so that the disk cannot be seen by the controller or The disk has been removed If an administrator selects a disk from an enclosure the disk properties are displayed. Location Model Manufacturer Serial Number Capacity State If the disk selected is a Global/Local spare this will also be displayed. Takes the administrator to the Select RAID from Table screen, which displays a summary of all RAIDs on the system. This returns the administrator back to the RAID Properties screen. Table Creating a RAID The FS3102 system is shipped preconfigured with a global spare and one RAID level 5 created on the rest of the disks in the system. For most applications this should be sufficient, however if this does not suit the users requirements, the RAID can be deleted and new RAID(s) created as required. Refer to Appendix A RAID Features for more detailed information on optimizing the RAID configuration. RAID Create is made up of three screens. These are; Configuring the RAID Options Selecting the Disks Confirmation of RAID creation Configuring the RAID Options The following screen is used to configure RAID Options (Figure 3-4) Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 31 of 109

32 Figure 3-4: RAID Create - Configuration Options Screen Complete the following steps to configure the RAID options: 1. Select the profile that best fits the application environment that the RAID will be used. The following are the available profiles. (The RAID Profile field allows the controller to optimise RAID and cache configuration based on the expected access pattern to the Logical Volumes on the RAID). Refer to for more detailed information. Workstation/CAD File Server Media Server Database 2. Select the level of the RAID to be created. The current options available are RAID levels 0, 1 and 5. NOTE: To create a RAID 10 select RAID 1 and select multiples of two disks. 3. Enable Write Cache so the controller will respond with Good status when the data is written to the cache, but before it is written to disk. 4. Enable Read Cache so the controller will store the data most recently retrieved in the cache. 5. Enable Read Ahead so the controller will read ahead to optimize performance on sequential reads. 6. Select Auto Rebuild so that if a RAID becomes degraded (i.e. a disk fails) it will be automatically rebuilt if a spare is available. This option can either be disabled, ASAP or background. If this option is disabled then an administrator has to initiate the rebuild. If it is set to background then the rebuild takes a lower priority than normal operations that occur on the system. If it is set to ASAP, then the rebuild will be done as quickly as possible while still allowing reading and writing. The Auto Rebuild option is not available for RAID level 0. NOTE: The performance of the system will slow down during a rebuild. IMPORTANT: When rebuilding a RAID the administrator should not remove the faulty disk until the rebuild is complete.

91 Appendix A RAID Features RAID Levels The controller supports RAID levels 0, 1, 5 and 10. Note: RAID 10 is not available as an option in the drop down menu for RAID level. To create a RAID 10, select RAID 1 from the drop down menu and select the quantity of drives in multiples of two. RAID Level Definitions RAID stands for Redundant Array of Independent Disks. A RAID system consists of two or more disks working in parallel. They appear as one drive to the administrator, and offer enhanced performance or security (or both). The software to perform the RAID-functionality and control the hard disks can either be located on a separate controller card (a hardware RAID controller) or it can simply be a driver. RAID-systems are based on IDE, SCSI, SATA and FC (fibre channel) disks. There are different RAID levels, each suiting specific situations. RAID levels are not standardized by an industry group. This explains why companies are sometimes creative and come up with their own unique implementations. Below is an overview of the most popular levels: RAID 0 In a RAID 0 system, data are split up in blocks that get written across all the drives in the array. By using multiple disks (at least 2) at the same time, RAID 0 offers superior I/O performance. This performance can be enhanced further by using multiple controllers, ideally one controller per disk. Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 91 of 109

92 Advantages Disadvantages Ideal use RAID 0 offers good performance, both in read and write operations. There is no overhead caused by parity controls. All storage capacity can be used, there is no disk overhead. The technology is easy to implement. RAID 0 is not fault-tolerant. If one disk fails, all data in the RAID 0 array are lost. Reliability is much less than a single disk. It should not be used on missioncritical systems. Any media errors cause data loss. Not recommended for any critical applications. RAID 1 (Mirroring) Data are stored twice by writing them to both the data disk (or set of data disks) and a mirror disk (or set of disks). If a disk fails, the controller uses either the data drive or the mirror drive for data recovery and continues operation. You need at least 2 disks for a RAID 1 array. RAID 1 systems are often combined with RAID 0 to improve performance. Such a system is sometimes referred to by the combined number: a RAID 10 system. Advantages Disadvantages Ideal use RAID 1 offers excellent read speed and a write-speed that is comparable to that of a single disk. In case a disk fails, data do not have to be rebuild, they just have to be copied to the replacement disk. The main disadvantage is that the effective storage capacity is only half of the total disk capacity because all data get written twice. RAID-1 is ideal for mission critical storage, for instance for accounting systems. It is also suitable for small servers in which only two disks will be used. RAID 1 is a very simple technology. Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 92 of 109

93 RAID 5 RAID 5 is the most common secure RAID level. Data is subdivided (striped) and transferred to disks by independent read and write operations. The data chunks that are written are also larger. Instead of a dedicated parity disk, parity information is spread across all the drives. You need at least 3 disks for a RAID 5 array. A RAID 5 array can withstand a single disk failure without losing data or access to data. Often extra cache memory is used on these controllers to improve the write performance. Advantages Disadvantages Ideal use Read data transactions are very fast while write data transaction are somewhat slower (due to the parity that has to be calculated). Disk failures have an effect on throughput, although this is still acceptable. RAID 5 is a good all-round system that combines efficient storage with excellent security and decent performance. It is ideal for file and application servers. RAID 10 RAID 10 combines the advantages (and disadvantages) of RAID 0 and RAID 1 in a single system. It provides security by mirroring all data on a secondary set of disks (disk 3 and 4 in the drawing below) while using striping across each set of disks to speed up data transfers. Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 93 of 109

94 Stripe Size Each RAID can consist of up to a maximum of 12 disks. Stripe Unit Size The Stripe Unit size is set by the profile. Caching The Raidtec FS3102 comes with 256 MB of cache memory as standard. The system supports up to 1 GB as an option. The cache memory is used for both read and write data. There are three kinds of caching implemented by the system firmware. Read Cached Data The system records the number of read and write commands that occur in the same physical stripe. When the number of commands exceeds a preset threshold, the system will allocate storage space to cache this data. This increases performance because subsequent read operations can be serviced from memory instead of reading from the disk. Streaming Read Data The system records the starting block and block size of each SCSI command received. When the start block of a new command matches the last block of a previous command the system detects that there is a stream of commands in progress and prefetches data up to 16 times the size of the original command. This increases performance by lowering the latency of subsequent commands in the stream. Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 94 of 109

95 Write Cached Data When write caching is enabled, Good status is returned immediately after the Data In phase, before the data is written to disk. This increases performance in two ways. Firstly it lowers command latency to the host. Secondly, by coalescing contiguous write data into larger segments before it is written to disk, seeks are reduced and bandwidths increased. NOTE: If write caching is enabled, data may be lost if power is removed prior to the data being written to the disks. If write caching is enabled, a UPS or/and the BBU should be used in the system.

When a RAID level 5 is created, the parity in the volume must be initialized. The RAID controller will read every stripe, calculate parity and write the parity. This can take several hours depending on the size of the disks. The RAID is made available from when it is created, but full performance is not achieved until the RAID is fully initialized. NOTE: 2 GB of each disk is reserved for reallocated blocks by the controller. Therefore the capacity formed will be slightly less than the nominal capacity available from the drives. NOTE: Usable drive capacities are fixed to allow drives to be used from different manufacturers. The result is that some capacity may be lost due to the difference in actual capacities between different manufacturers even though the nominal capacity is the same. NOTE: If the disks that are being used to form the RAID have different capacities, the RAID will be created using the smallest disk capacity of the different disks. Additional capacity on larger disks will be lost. RAID Expansion The Raidtec FS3102 system supports online expansion of the RAID. This expansion is accomplished in two possible ways, by row or by column. The controller decides what the best way of expanding the RAID is. The administrator does not have the ability to choose the expansion method. Expansion By Row The RAID will be expanded by row if possible. To expand by row, the number of disks that are being added to the RAID must be the same number that are in the RAID that is being expanded. The RAID will be expanded by adding an additional row of disks to the RAID. The number of columns in the RAID will Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 95 of 109

96 remain the same. If the original RAID was level 5, the controller will have to initialize parity for the new row. NOTE: If the disks that are being used to form the additional row have different capacities, the row will be expanded using the smallest disk capacity of the disks being added. Additional capacity on larger disks will be lost. The capacity of the disks in the new row can be different from the first row of disks. Expansion By Column If there are insufficient disks to form an entire new row, the RAID will be expanded by adding columns to the stripe. This involves adding extra disks to each row (this will be a single row unless the RAID has already been expanded by adding an additional row). When this is done, a re-striping operation is necessary. The system reads each stripe in turn and writes it to an expanded stripe. This is a time consuming operation. NOTE: Expansion by column will expand the RAID using the same disk capacity that was used in the existing columns. If the disks that are being used to expand the RAID have smaller capacities than the columns already in the RAID, the expansion will not be allowed. If the disks that are being used to expand the RAID have larger capacities than the columns already in the RAID, the additional capacity on the larger disks will be lost. RAID Verify A RAID level 5 may be checked for valid parity by initiating a verify operation. The system reads each stripe and checks for valid parity. At the end of the verify process the system sends an Alert if any stripes were found with invalid parity. Logical Volumes The controller supports up to 128 independent logical volumes connected across 16 hosts. Auto Rebuild The Raidtec FS3102 has 3 rebuild options if a RAID becomes degraded. These are disabled, ASAP and background. These options can be set in the Raidtec Manager RAID Modify screen. Background is the default setting. The RAID can still be accessed during a rebuild, but performance will be reduced. Note: If a verify is scheduled when a rebuild is in progress, the verify will not take place. Disabled If Auto Rebuild is set to Disabled, the RAID will not rebuild unless the administrator manually selects Rebuild in the Raidtec Manager RAID Modify screen. If a RAID becomes degraded, an alert will still be generated even if Auto Rebuild is set to disabled. ASAP If Auto Rebuild is set to ASAP, the RAID will rebuild as quickly as possible while still allowing reading and writing to occur. Read and write performance may be substantially reduced from normal operation. Background If Auto Rebuild is set to Background, the RAID will rebuild, but priority will be given to normal read and write operations. If there is a high level of read and write activity, the rebuild may take a long time. Raidtec FS3102 RAID Manager User Guide Version 1.0 Page 96 of 109
