AbstractMaking the Right Storage Choice for your VirtualizedServer EnvironmentLearn about the IBM Storwize V7000 disk system and how itcan provide better storage performance, utilization andproductivity in a virtualized server environment such asVMware or Microsoft Hyper-V. Integrating storage efficiencytechniques, including thin provisioning and automated datatiering, can provide dramatic benefits to your business. 1

Agenda Multi-platform support enhances flexibility Performance optimization can help identify and resolve bottlenecks Built-in advanced functionality reduces costs High Availability and Disaster Recovery features reduce application downtime 2

Are you running two or more Hypervisors?• In a recent survey, 44 percent of respondents indicated they were running two or more Hypervisors* IBM is a Global Partner supporting Red Hat Enterprise Virtualization (RHEV) based on Linux KVM IBM is a VMware Global Alliance Partner and the leading reseller of VMware solutions IBM supports open source Xen, including Citrix XenServer and OracleVM IBM is a Gold Certified IBM has been doing server Partner and supports virtualization for the past 40 years Hyper-V virtualization and supports PowerVM and zLPAR * Source: http://www.thehotaisle.com/2009/10/01/cloud-soup 3

IBM Storwize V7000 disk system • Multi-Platform support for different hypervisors • External Storage across a shared network to enable Live Mobility of VM guests – Fibre Channel Protocl (FCP) – iSCSI for Gigabit Ethernet • Enterprise-class performance and built- in functions for storage efficiency and data protection • Non-Disruptive migration and upgrades for high availability 4

Start Small and Grow Easily Scale Up Drive sizes can be intermixed Easily add up to 9 expansion in an enclosureDrive choices enclosures 12- and 24-bay expansion enclosures• 2.5-inch (SFF) Expand to hundreds of TB can be intermixed in a system – 300GB SSD Grow Big – 300GB 10K RPM – 450GB 10K RPM – 600GB 10K RPM• 3.5-inch (LFF) – 2TB 7200 RPM 20 U Start small One 12- or 24-bay control enclosure 2U 5

Innovative and Elegant Architecture • Volumes are a logical representation – Portions of each volume can reside on SSD or HDD, internal or external – Stripe across many disks to optimize performance – Migrate volumes from one storage tier to another • Easy Tier™ provides External automated tiering Virtualization – Busy portions moved to SSDSSD – Less active moved to HDD HDD +Internal Storage – Can use internal and external SSD and HDD External Storage 7

Easy Tier Application Transaction Improvement Application Transactions No change to the database 240% from or application Original No work to brokerage identify active transaction indexes No manual movement of files or volumes Just turn it on Easy Tier Easy Tier and let it Learning Movement work! 8 8

Built-In Advanced Functions With IBM Storwize V7000, many functions are included at no additional charge that you would pay for otherwise – Thin provisioning - storage is not allocated until data is written for higher disk utilization – Local replication - full copy or thin provisioned replicas (snapshots) of volumes offloads server resources from hypervisor hosts – Easy Tier™ - automated tiering between SSD and HDD storage – Non-disruptive data migration within and between internal and external storage 11

All Storwize V7000 Storage is Virtualized • Storwize V7000 virtualizes internal storage – Volumes allocated across RAID ranksSSD Internal Storage HDD • Storwize V7000 also virtualizes external Fibre Channel storage +External Virtualization – Inherit rich Storwize V7000 functionality • Extends life of existing storage assets • Protect investment in existing capacity – Migrate data to internal or keep external • Improve availability by practically eliminating storage-related causes of downtime External Storage 12

Volume Mirroring• IBM Storwize V7000 can store two copies of a volume on separate storage pools – Storwize V7000 writes to both copies in sync• If disk supporting one copy fails, Storwize V7000 provides continuous data access by using other copy – Copies are automatically resynchronized after repair• A local high availability function to protect critical data against system failure• Either copy can be split off to be used as production copy• Copies may be thin-provisioned, enabling thick-to-thin conversions 14

Extended Distance Mirroring Metro Mirror (synchronous) Global Mirror (asynchronous) • Up to 300km between sites • Up to 8000km distance • Host waits until data stored at • Host does not wait, reduces both locations impact to application • Designed to maintain identical • Designed to maintain consistent secondary copy secondary copy Provides support for VMware Site Recovery Manager, PowerHA, and Tivoli Storage Productivity Center for Replication (TPC-R) 15

Summary and Next Steps• Make the right storage choice for your server virtualization environment!• Consider the IBM Storwize V7000 – Supports multiple hypervisor platforms – Improves performance, identifies and resolves bottlenecks – Built-in advanced functions reduces costs – High availability features reduce application downtime• Technical white papers are available! – Deploying IBM Storwize V7000 in VMware Environments – Highly Available Virtual Machines with IBM Storwize V7000 and Microsoft Hyper-V Available online: ibm.com/support/techdocs 16
