6 IBM CERTIFICATION LETTERS

7 HITACHI ADDED VALUE FOR MAINFRAME - Hitachi brings storage virtualization technology to the mainframe space - HDP for Mainframe provides FCSE/DVE/EAV compatibility - HDP is technology foundation for the next wave of mainframe virtualization -Universal Volume Manager -Utilize existing assets or low-cost external storage -Dynamic Provisioning -I/O load balancing -Flexible volume allocation -Better space efficiency EAV DVE EAV DVE EAV DVE HDP Pool FCSE EAV DVE -Automatic Dynamic Tiering -Effective use of highspeed SSD EAV DVE EAV DVE SSD EAV DVE HDP Pool + HDT SAS EAV DVE SATA FCSE UVM EAV DVE UVM SAS UVM

8 APPLYING HITACHI TECHNOLOGY TO IT CHALLENGES Business Demands, Complexity, Increased Risks, Staffing People Technology Differentiators Management Systems & Benefits Process Management Simplification Reduced Cost Improved Productivity Improved RTO/RPO Consolidation, High Availability and Security USP V and VSP designed and built for Zero Downtime operation Highest Performance and Scalability Hardware-based Encryption for Data at Rest Lower TCO Increase ROA Leverage Hitachi Storage Virtualization to attach lower Cost External Storage Deployment of Virtual Tape Library Solutions for long term Archival on Disk instead of Tape Backup In-System Replication Technology such as ShadowImage and Flashcopy provide Disk-to-Disk backup to minimize backup Window Disaster Recovery Hitachi Universal Replicator for 3-Data Center DR Cascading and/or Multi-Target Topologies Basic Hyperswap No Impact on Host Resources

9 REMOTE REPLICATION FOR DISASTER RECOVERY 2 DATA CENTERS Synchronous limited by distance Achieving RPO of Zero and Fast Recovery Time With Automation Solutions (IBM s GDPS or HDS Basic Hyperswap) able to achieve RTO of almost Zero Primary Site In-Region Recovery Site 2DC Synchronous P-VOL TrueCopy Sync S-VOL Asynchronous no distance limitations No Host Impact on Response Times Offloads MIPS and reduces cost by replacing host based replication methods Data Movement Overhead is on Out-Of Region Array (Pull Technology) Journaling maintains update sequence Integrity RPO measured in seconds, RTO in minutes (and is application dependent) Primary Site Out-of Region Remote Site 2DC Hitachi Universal Replicator P-VOL S-VOL Asynchronous Asynchronous JNL JNL

10 REMOTE REPLICATION FOR DISASTER RECOVERY 3 DATA CENTERS Combination of Synchronous and Asynchronous Replication Technologies Leveraging HUR Journaling alleviates impact of Link Failures and Cache limitations No Data loss upon loss of Primary Site HUR Cascade Data volumes in Intermediate Site shared as TCs Secondary and HUR Primary Volumes 3DC Cascade HUR Multitarget Primary Site Intermediate Site Remote Site P-VOL TrueCopy Sync GDPS S-VOL P-VOL Provides Delta Resynchronization upon Primary Site Failure JNL HUR Asynchronous BCM S-VOL Can be combined with Automation Solutions e.g. TPC-R Basic Hyperswap, GDPS etc. Primary Site Intermediate Site Remote Site JNL 3DC Multitarget P-VOL JNL Hitachi Universal Replicator Asynchronous S-VOL JNL TrueCopy Sync GDPS S-VOL JNL BCM Delta Resync

12 HITACHI DYNAMIC TIERING AT THE PAGE LEVEL A MORE EFFICIENT APPROACH One pool of pages now spans multiple tiers of storage Volume Data is written to the highest performance tier first Least Referenced POOL A EFD/Flash TIER 0 SAS TIER 1 Less active volume pages migrate to lower tiers Pages can be promoted based on Heat Index Volumes no longer have to be moved to optimize performance Volumes can span across tiers on external storage Least Referenced SATA TIER 2

13 IOPS HDT - STORAGE RESOURCES AS TIERS RELOCATING DATA BASED ON BACKEND IO LOAD Tier 1 Each DPVOL is analyzed and relocated in turn Page IO Weights & Tier Ranges Page relocations IOPS break point where pages higher than this level are relocated to T1 Tier 2 Cycle 0 IOPS break point where pages destined for T2 and T3 is determined Page Tier 3 Monitor physical IO to pages

14 IOPH HDT TIER ALLOCATION POLICIES Tiering Policies - Default ALL Level 1 = Tier1 Level 2 = Tier1+Tier2 Level 3 = Tier2 Level 4 = Tier2+Tier3 Level 5 = Tier3 ALL LEVEL1 LEVEL2 Tier1 LEVEL3 LEVEL4 Tier2 LEVEL5 Tier3 New Tiering Policies based on a maximum % of the used pages in a DPVOL that can be placed in a tier (Level 6-32) 600GB VOL 200GB data Flexible Tier Policy: T1 = 10-20% T2 = 40-90% T3 = 0-30% 25GB 145GB 30GB Tier1 Tier2 Tier3 Limit the amount a DPVOL can use per tier

15 DFSMS STORAGE GROUPS AND MF HDT Tiered Storage can be implemented with DFSMS Storage Groups DFSMS Attributes such as Data Class and Storage Class are used to direct allocation to the right Tier Subsystem SG1 SG2 SG3 With MF HDP may combine all SG s into one and use HDT to move data to the right Tier automatically based on Workload performance SSD Tier 0 SAS Tier 1 NL-SAS Tier 2 HDT Storage Group Subsystem ONE SG HDP Volumes are managed at page-level

16 INTRODUCING TIER POLICY MANAGEMENT HITACHI TIERED STORAGE MANAGER FOR MAINFRAME Assign Tiering Policies for Volumes/Storage Groups in V6 Includes Monitoring and reporting capabilities Later will be able to control Tiering Policies at Dataset Level ISPF Batch CLI HTsM for Mainframe CLI CCW CCW HTsM for Mainframe VOL1 VOL5 CCW VOL2 VOL3 VOL6 CCW VOL4 VOL7 VSP DS1 DS2 DS5 DS3 DS6 DS4 DS7 VSP
