27. Dynamic Disk Pool Pain points of legacy RAID • Legacy Admin is Complex • SA must define RAID groups • Decide on how many drives per group • Pick RAID levels • Manage hot spares • I/O performance is limited by the spindles in a group • Drive failure recovery can takes days or weeks with 2TB or 3TB drives • Group performance may drop 30% to 50% • With roadmaps from drive vendors showing 24TB drives, recovery could literally take months • The system is susceptible to additional drive failures Dell Confidential - NDA

28. Dynamic Disk Pooling (DDP) Overview • Dynamic Disk Pooling (DDP) is another system of underlying volume configuration • “Distributed RAID” • Maximize capacity and data security • DDP dynamically distributes data, spare capacity, and protection information across a pool of drives • Segments are dynamically recreated/redistributedas needed to maintain balanced distribution • Significantly faster return to optimal state following a drive failure (all drives participate in reconstruction) Dell Confidential - NDA

29. Dynamic Disk Pooling (DDP) Performance protection • Traditional RAID Volume • Delivering consistent performance to maintain SLAs • Stay in the “green zone” • Performance drop is minimized following drive failure • Large pool of spindles reduces hot spots • Each volume spread across all drives in pool • Dynamic distribution/redistribution is a non-disruptive background • operation 4+ DAYS 2.5 DAYS 1.3 DAYS No Impact Hours Dell Confidential - NDA Typical Rebuild Improvements Based on 24-drive Mixed Workload

30. Dynamic Disk Pooling (DDP) Data protection with built-in value • DDP Builds on Traditional RAID • Unmatched protection against drive failures and errors • Shorter recreation times reduces exposure to multiple cascading disk failures • Any stripes experiencing multiple drive failures are given reconstruction priority • Protects against unrecoverablemedia errors during reconstruction • Provides significant improvement in data protection • Larger pool provides even greater protection RAID Rebuild Time DDP Recreation Dell Confidential - NDA

31. Dynamic Disk Pooling (DDP) • Budget Protection • Doing more with less was never easier • Simplified administration lowers management costs • Optimally configure storage with minimal effort • Shared capacity for volume expansion • Eliminates hot spare administration • Ability to stay in the “green zone” drives higher revenue and reduces unexpected costs • No more repercussions from drive failure • Powerful versatility ensures successful implementation in any environments • Right-size for any environment • Multiple ways to create storage tiers Dell Confidential - NDA

32. VMware vStorage APIs for Array Integration VAAI Support • Full copy enables the storage arrays to make full copies of data within the array without having the server read and write the data • Block Copy enables storage arrays to copy a single block to some LBA range to speed up provisioning of virtual machines (Write Same/Zero) • Hardware Assisted Locking provides an alternative means to protect the metadata for VMFS cluster-file systems, thereby improving the scalability of large server farms sharing a datastore Dell Confidential - NDA

33. ALUA (Asynchronous Logical Unit Access)Benefits • Improved Flexibility and IT Efficiency • Flexible configuration accommodation • Automatic interface / ownership optimization • Eliminates environmental complexity • Faster deployment of new OS / HBA & drives Dell Confidential - NDA

34. Pre-ALUA Path Failure example • IO is only serviced by the controller that owns the volume. • Path failure is reported up to the MP driver. Server 1 (host) A Controller multipath driver HBA driver HBA HIC VOL 1 switch HBA x Server 2 (host) B Controller multipath driver HBA driver HBA HIC HBA switch Dell Confidential - NDA

35. Pre-ALUA Path Failure example • The host initiates a Volume Transfer to issue IO to the volume on the alternate path. • Volume is transferred and IO resumes. Server 1 (host) A Controller multipath driver HBA driver HBA HIC switch HBA x Server 2 (host) B Controller multipath driver HBA driver HBA HIC VOL 1 HBA switch Dell Confidential - NDA

36. ALUA Path Failure example • The host sends IO to the non-owning controller • IO shipping is used to route IO from the non-owning controller to the owning controller. Server 1 (host) A Controller multipath driver HBA driver HBA HIC VOL 1 switch HBA IO Shipping x Server 2 (host) B Controller multipath driver HBA driver HBA HIC HBA switch Dell Confidential - NDA
