  18. 18. IBM System Storage: Optimized systems. Optimal innovation.SAS Controllers and Expanders Chain 2 Chain 1  A string of enclosures on a SAS chain are connected via two Strands – Each Strand is an independent SAS domain (network) providing redundancy to the enclosures and associated disk drives  A SAS Expander is basically a switch with point to point connection to every drive in the enclosure  Two Expanders per enclosure – One per canister allowing access to a given disk drive per a SAS chain by either node canister for redundancy18 © Blue Power Technology 2012
  19. 19. IBM System Storage: Optimized systems. Optimal innovation.SAS Ports and Cables SAS SAS Phy Physical SAS LEDs Port Cable Port Link Phy Phy Phy Phy Phy Phy Phy Phy  A phy contains a transceiver (transmitter + receiver)  A physical link connects two phys and contains a pair of wires for full duplex transmission at 6 Gbps  A SAS port on the Storwize V7000 contains four phys  A SAS cable contains four physical links or lanes with total transmission bandwidth of 24 Gbps19 © Blue Power Technology 2012
  20. 20. IBM System Storage: Optimized systems. Optimal innovation.SAS Ports and Cables  SAS cables always connect from one top enclosure canister to another top enclosure canister and from one bottom enclosure canister to another bottom enclosure canister in a SAS Chain – Never connect the top canister of one enclosure to the bottom canister of another enclosure or vice versa • Errors will be logged indicating the system is miss cabled  Expansion Enclosure – An expansion enclosure connects to only one SAS chain – No restrictions on which SAS chain an enclosure connects to • Can connect 5 enclosures to chain 1 before adding any to chain 2 Not recommended for RAID 10 as code tries to use drives from both chains for enclosure loss protection and/or SAS chain failure protection – Intermix of 12 or 24 drive enclosures on same chain supported20 © Blue Power Technology 2012

  31. 31. IBM System Storage: Optimized systems. Optimal innovation. Hot-spots Optimized performance and throughputIBM Easy Tier Transparent reorganization  What is Easy Tier? – A function that dynamically re- distributes active data across multiple tiers of storage class based on workload characteristics  Automatic storage hierarchy ● Hybrid storage pool with 2 tiers = Solid-State Drives & Hard Disk Drives ● I/O Monitor keeps access history for each virtualisation extent (16MiB to 2GiB per extent) every 5 minutes ● Data Placement Adviser analyses history every 24 hours ● Data Migration Planner invokes data migration  Promote hot extents or demote inactive extents – The goal being to reduce response time – Users have automatic and semi-automatic extent based placement and migration management SSDs HDDs SSDs HDDs Automatic Relocation  Why it matters? Optimized performance and throughput Hot-spots – Solid State Storage has orders of magnitude better throughput and response time with random reads – Full volume allocation to SSD only benefits a small number of volumes or portions of volumes, and use cases – Allowing dynamic movement of the hottest extents to be transferred to the highest performance storage enables a small number of SSD to benefit the entire infrastructure31 – Works with Thin-provisioned Volumes © Blue Power Technology 2012

  34. 34. IBM System Storage: Optimized systems. Optimal innovation.Thin-provisioning  Traditional (“fully allocated”) virtual disks use physical disk capacity for the entire capacity of a virtual disk even if it is not used  With thin-provisioning, Storwize V7000 allocates and uses physical disk capacity when data is written Dynamic growth Without thin provisioning, pre-allocated space is With thin provisioning, applications can grow reserved whether the application uses it or not dynamically, but only consume space they are actually using  Available at no additional charge with base virtualization license  Support all hosts supported with traditional volumes and all advanced features (EasyTier, FlashCopy, etc.)  Reclaiming Unused Disk Space – When using Volume Mirroring to copy from a fully-allocated volume to a thin- provisioned volume, Storwize V7000 will not copy blocks that are all zeroes – When processing a write request, Storwize V7000 detects if all zeroes are being written and does not allocate disk space for such requests in the thin-provisioned volumes • Helps avoid space utilization concerns when formatting Volumes  Done at Grain Level (32/64/128/256KiB)  If grain contains all zeros don’t write34 © Blue Power Technology 2012
