2 What is Host Software?

3 Simultaneous development efforts

4 NextGeneration Virtual Storage Meets Server Virtualization Benefits of VMware Virtual Infrastructure Maximum consolidation to reduce data center footprint Ease of use Increased resiliency Streamline deployment and configuration processes Automatic and dynamic load balancing (VMotion) Why wouldn t you want the same capabilities in your storage?

5 VMware - vstorage APIs vstorage APIs deliver tight integration of advanced capabilities from storage partners with the Virtual Datacenter OS from VMware. vstorage APIs for array integration will enable customers to leverage array-based capabilities, such as snapshots, provisioning, replication and restore, directly with individual virtual machines in conjunction with the clustering and pooling capabilities of VMwareInfrastructure.

6 VMWare Production Recovery Virtual Center SRM SRM Virtual Center VMware Infrastructure VMware Infrastructure

7 VMware Side Recovery Manager Block Diagram Production Recovery Virtual Center SRM SRM Virtual Center VMware Infrastructure VMware Infrastructure SRA SRA XIV Storage Mirror/Snap XIV Storage

8 What SRM Does Automate DR failover and tests Playback of what was programmed into VirtualCenter during setup Benefits Speed: recovery starts with a single click Simplicity: Most effort is in setup Reliability: This virtual runbook is the same as is used for all tests

9 XIV SRA for VMware SRM Make VC aware of XIV replication Setup: Discovers which VMs are replicated by Querying XIV array for replicated LUNs Matching replicated LUNs to datastores and VM inventory Failover: Automates promotion of LUNs at remote site Test: Automates LUN snapshot creation/deletion for test Support: ESX 3.5, 4.0 VSphere 4 Sync and Async

10 Microsoft Cluster Server Introduction Also known as Failover Clustering starting Windows 2008 Provides high availability for Windows Server-based services and applications Two modes local cluster and geographically dispersed cluster In Geo-Cluster, storage required to provide replication Synchronous replication often referred to as Metro-Cluster Windows 2008 added various quorum options other than single quorum disk Majority Set Nodes File Share Witness

11 MSCS Geo-Cluster Architecture Shared File Quorum Clients Main Site Data Replication HA Site

12 MSCS Geo-Cluster Architecture Shared File Quorum Clients Main Site is Down Replication is Down, HA Site Storage does Switch_Role HA Site takes over

13 MSCS Geo-Cluster Architecture Shared File Quorum Clients Main Site is back Replicating back Failback scenario support HA Site

14 XIV support of MSCS Employing the Big Red Button scheme Due to the danger of data loss on rolling disasters Failback support Support for Windows 2003, 2008, 2008 R2 Support for Sync replication (ASync support coming soon) Includes configuration verification tool

15 SAP There are two aspects for storage system sizing: capacity and performance To estimate I/O profile and size storage for SAP environment: Quicksizer tool estimate I/O profiles for planned SAP installations Use actual IO/s performance measurements in existing installation Storage system are sized based on number of SAPS it can service: ERP (OLTP) 1 SAPS is equivalent to approx. 0.4 IO per sec BW/BI (OLAP) 1 SAPS is equivalent to approx. 0.6 IO per sec The service time performance constraints of a SAP ERP application: between 5 and 7 ms - expected between 10 and 15 ms - considered good above 20 ms - considered as performance bottleneck beyond of 30 ms - system does not behave as expected towards the users

16 Measured OLTP Performance OLTP Performance from single IBM Power 520 No model but real performance (old HW, R2.0) Be aware that we used only four IF module! Best pracitce would be to use all six.

17 SAP OLTP Workload with XIV Typical Random OLTP Workload with 70/30/50 and 8kB Blocksize Guideline: XIV can handle up to IOPS with < 15ms OLTP 70/30/50 OLTP 50/50/50 OLTP 30/70/50 Service Time in ms (Open) Total I/O Rate (I/Os per second)

18 Introducing Tivoli Storage FlashCopy Manager You ve heard of NetApp Snapshot and NetApp SnapManager? IBM FlashCopy and IBM Tivoli Storage FlashCopy Manager offer a compelling alternative solution for IBM and virtualized non-ibm storage environments. FlashCopy DS8000 XIV DS3/4/5 SVC Create instant application copies for backup or application testing Make better use of space with incremental (only changed blocks) or space-efficient (thin provisioned) snapshots FlashCopy features differ between devices FlashCopy Manager* Application System Integrated, instant copy for critical applications Virtually eliminate backup windows Rapidly create clones for application testing View inventory of application copies and instantly restore Optional TSM backup integration

19 IBM Tivoli Storage FlashCopy Manager Application System FlashCopy Manager Application Data Snapshot Backup Snapshot Restore Local Snapshot Versions Online, Online, near near instant instant snapshot backups with with minimal performance impact impact High High performance, near near instant instant restore restore capability For IBM XIV Storage Storage Manager 6 With Optional TSM Backup Integration Integrated with with IBM IBM Storage Hardware Simplified deployment 1

20 Client References Stihl migrated more than 100 of its servers with AIX, Linux, VMware and Microsoft operating systems to the XIV storage systems HR Group migrated all of its servers with IBM AIX and Linux operating systems and SAP Application with Oracle Real Application Clusters (RAC) and General Parallel File System (GPFS) to the new storage systems. The XIV Storage System platform automatically balances load across applications and improves performance levels Deutsche Post IT Brief runs a couple of operating systems and applications on the System Storage XIV Storage System, which it uses primarily as the base platform for VMware
