3 Storage Virtualization IBM

4 The benefits of Server Virtualization Common Infrastructure Common Management Pay-per-use Accounting More Flexibility Improved Availability UNIX W2K LINUX UNIX W2K LINUX SAN Storage Virtualisation is the Next Step! 4

6 Benefits of External Storage Virtualization View all storage as one virtualized storage pool, independent of physical location Ability to consolidate and integrate 3 rd party storage systems into one multitiered storage architecture Exploit the advanced storage software with all externally attached storage systems Common management and business continuity software Any-to-any replication between all attached systems Add the enterprise storage capabilities to other midrange modular or legacy storage systems 6

7 Thin Provisioning IBM

8 Thick versus Thin Capacity Provisioning Dynamic growth Without thin provisioning, pre-allocated space is reserved whether the application uses it or not. It is static With thin provisioning, applications can grow dynamically, but only consume space they are actually using. More productive use of available storage. Improve storage utilization Decrease CAPEX and OPEX 8

9 Initial Buy / install Upgrade Upgrade Upgrade Initial Buy / install Upgrade Upgrade Upgrade Thin Provisioning decreases the operating costs Without ThinProvisioning With ThinProvisioning Impact on group: Application Group Server Admin NOT NEEDED SAN Team Storage Admin Production lifecycle 9

10 What is Page Zeroing? Physical Volume Virtual Volume Volume after page zeroing Server volume 1 2 Fat to Thin migration Unused pages to return physical storage to Thin provisioning pool Decreases the capital expenses 10

11 Storage system performance optimization IBM

12 IBM EasyTier SSD Management for performance SSDs HDDs SSDs HDDs Automatic Data relocation Hot-spots due to poor data layout. Optimized performance and throughput. 12

13 Domino DB2 Exchange Easy Tier Process Storwize V7000 Node Volume Easy Tier Code IOM DPA DMP DM A hot spot is formed on a magnetic disk when an application makes frequent use of the same area or extent of a volume The I/O Monitor captures access patterns and generates usage statistics sending them to the Data Placement Advisor The Data Placement Advisor identifies hot spots and outputs potential data migrations to the Data Migration Planner The Data Migration Planner performs analysis to deliver recommended data migration plan to the Data Migrator based on the physical storage characteristics Data Migrator confirms and schedules data migration activity based on the data migration plan using SVC function to seamlessly relocate the data to higher performing storage without any application interruption Magnetic Disk SSD

14 Storwize V7000 introduction IBM

15 Modularity and Advanced Software Functions Enclosures contain up to twelve 3.5 or twenty-four 2.5 drives in just 2U Control enclosure: dual active-active controllers and drives; Expansion enclosure: drives only Up to nine expansion enclosures attach to one control enclosure Mix drive sizes and HDD/SSD in enclosure Modular Hardware Building Blocks in 2U Eight 8Gbps FC ports plus four 1Gbps iscsi ports per controller pair; 16GB cache per controller pair Software inherited from prior offerings plus enhancements 2U New advanced software functions New GUI (easy-to-use, web based) RAS services and diagnostics Additional host, controller and ISV interoperability Integration with IBM Systems Director Enhancements to TPC, FCM and TSM support 15 Proven IBM software functionalities Easy Tier (dynamic HDD/SSD management) RAID 0, 1, 5, 6, 10 Storage virtualization (internal and external disks) Non-disruptive data migration Global & Metro Mirror FlashCopy up to 256 copies of each volume Thin provisioning
