2 SIOS Technology Corporation Founded in November 1999 (SteelEye Technology Inc.) to follow-on all LifeKeeper activities from NCR Since 2006 part of SIOS Technology, Tokyo Company headquarter in San Mateo, USA Partnerships with Citrix, EMC, HP, IBM, Intel, Microsoft, SAP, VMware and many others Sales & Support through Value Added Distributors and Resellers worldwide Support through certified partners In 2004 founding of the first regional Competence and Support Center in Dresden for Central and Eastern Europe More than licenses in use worldwide 2

3 High Availability: Definition High application availability through software solutions such as Cluster, Fault Tolerance Concepts, Load Balancing Solutions, Protection against logical causes of failure by shadow databases, CDP approaches, Hardware with redundant components, Standby- Systems, Providing secure infrastructures like compute cells, USVs, virtualised solutions, Within a high availability concept suitable components are assembled into a customized solution. 3

4 SAP Protection Suite: Single Points of Failure (SPOF) These services has been identified being Single Points of Failure (SPOF): SAP NetWeaver Application Server SAP Message Service SAP Enqueue Service Datenbank SAP Message Service The SAP Message Service is required for information exchange between SAP instances and to regulate this exchange of information. SAP Enqueue Service The Enqueue Service organizes the blocking of business objects on the SAP transaction level. Database The database is in a special position from a performance and functionality point of view. Each ABAP work process at startup establishes a private connection to the database. Resources IP, File systems on LVM, NFS-Exports /sapmnt /usr/sap/trans 4

5 SAP HA-Interface Zertifizierung In the past the implementation of the HA solution was in the hands of the partners. This means that the responsibility for the proper handling of ASCS, DB and Central Instance lay in their hands, because proprietary solutions were used for the relocation. In 2012 SAP has started a certification process in order to standardize the use of the interface to the SAP start service (sapstartsrv): Certification of Start / Stop methods in an HA cluster A common HA setup for SAP NetWeaver 7.20 based systems Improved transparency in the relationships between OS, DB and HA solution Better transparency of responsibilities (support) With the certification minimum requirements are defined. The partner may at any time extend its solutions beyond. Seite 5 5

6 Interface to partner solutions Web-Service for Start, Stop and Monitor Integrated interface using shared lib or OS-Scripts OS-Scripts interact with the SAP HA-Script Connector (SAP) Shared lib and/ or OS-Scripts are delivered by the HA-Software-Partner Seite 6 6

8 Application Protection with SteelEye Protection Suite for Linux Application-oriented high availability solution Simultaneous operation of protected and unprotected applications Protection of critical applications and data Linux, Windows 2008/ 2012 Scalable: Intel-based Hardwareplatforms, 32- and 64-bit architecture Support of different storage technologies 8

9 Application: SAP Protection Suite Recovery Kit Protection of Services being identified as Single Point of Failure (SPOF) Is using SAP-internal utilities out of the kernel (Kit 6.2) / SAPHOSTAGENT-Package (Kit 7.4) Integration of the database Application Recovery Kit (ARK), NFS ARK, NAS ARK and LVM ARK for a complete protection of the system Supported are: - Active/ Active and Active/ Stand-by configurations Versions: - SAP NetWeaver 7.3 (Kernel 7.20) - older versions with the previous kit (without certification) - - Databases: Oracle, DB2 EE, MAX DB/ SAP DB - SLES10, SLES 11, RHEL 4.x, RHEL 5.x, RHEL 6 Requirement: SAP certified hardware 9

10 Application: SteelEye Protection Suite Configuration I SAP (ABAP) Switchover Configuration Active/Stand-by Active/ Active Configuration for DB and CI, AS is integrated unprotected 10

11 Application: SteelEye Protection Suite Configuration II SAP (JAVA) Switchover Configuration DB and SCS each implemented within a separate cluster 11

12 Application: SteelEye Protection Suite DR Configuration DB and SCS are implemented in separate clusters over two different data centers 12

13 VMware HA VMware HA responds to errors of host hardware and guest operating system VMware HA does not recognize any mistakes in the application within the VM 13

14 VMware HA plus vappkeeper VMware HA will continue to monitor and, if necessary, restore the entire system vcenter shows the status of the VM In case of an application failure vappkeeper detects the error and restarts the application and if necessary, the entire VM. 14

15 One Node Application Protection: vappkeeper Protection for virtualized applications and databases integrated in VMware HA and vcenter Based on the long-time proven technology of LifeKeeper Application Recovery Kits (ARKs) enable Single Node Protection for virtual machines Temporal based recovery logic Multi-level policies Maintenance mode Management Console complements the integrated vsphere client plug-in Supports VMware vsphere 4/5 15

16 Integrated in VMware vsphere 16

17 vappkeeper + VMware HA 17

18 Enterprise Management vsphere Client dashboard and granular application hierarchy views Brower-based user interface Command-line interface Extensive rules possible (i.e. temporal recovery logic, multi-level policies) 18
