  17. Storage Server Consolidation with Consolidation with Cut Storage TCO by 50% or more Cut Server TCO up to 70% Increase capacity utilization up to 75% Increase CPU utilization up to 80% Increase server to administrator ratio Reduce storage administration effort 90% from 10:1 to 30:1 Seconds Hours to provision new storage to provision a new server One command Drag and drop to optimize service levels / rebalance to optimize service levels / rebalance 3,500 kWh and $350 saved 6,800 kWh and $680 saved per year per usable TB per year per workload virtualized 50% or more reduction in floor space 70% or more reduction in floor space Simple and efficient Disaster Recovery for Simple and efficient Disaster Recovery for better and broader application recoverability better and broader application recoverability Complete Utility Computing: 3PAR + VMware

  18. Virtualization Reality • VMware consolidates physical servers at the cost of many virtual servers contending for narrowly striped disk access with traditional storage arrays

  19. Virtualization Reality: Memory Most Precious ESX Resource Before consolidation After 10x consolidation (estimated) Source: The Role of Memory in VMware ESX Server 3

  20. ESX Memory Management Prefers Fast Storage ESX Memory Mgmt. techniques for handling memory over-commitment: • Page sharing -- a proprietary transparent page sharing technique to securely eliminate redundant copies of memory pages (the most preferred memory reclamation technique) • Ballooning -- ESX Server works with a VMware-supplied vmmemctl module loaded into the guest operating system to reclaim pages that are considered least valuable by the guest operating system. To use ballooning, the guest operating system must be configured with sufficient swap space. (the guest OS will page in/out as balloon “deflates/inflates”) • Swapping --a reliable mechanism of last resort that the system uses to forcibly reclaim memory from a virtual machine and leads to significant performance hit.

  24. Virtualization Issue #3 • ESX likes large storage volumes • Large storage volumes offer the greatest flexibility for VMs Source: VMware SAN Design White Paper

  27. Use Array-Based Thin Provisioning when Available Thin provisioning is most cost-effectively implemented at the storage layer where TP can benefit all of a customer’s shared storage – both in and out of their VMware environment. • VMware TP does not replace array-based TP • No additional physical storage savings by adding VMware TP • 3PAR array-based TP is reservationless • Relieves ESX server CPU cycles • Admins can provision max sized LUNs upfront for “free” • No need to resize or modify datastore in the future

  28. Virtualization Issue #4 • Changes to the array from a drive standpoint traditionally very difficult and disruptive • adding new drives to a RAID-5 volume online • changing RAID levels online • changing a volume to use SATA vs. FC disks

  29. RAID 1 RAID 5 (2+1) RAID 5 (3+1) RAID 5 (8+1) Smart Dynamic Optimization: No complexity or disruption Fibre Channel Drives Nomigrations ! Performance Nearline Drives Transition non-disruptively and with one commandfrom one configuration to another until performance and storage efficiency appropriately balanced RAID 1 RAID 5 (2+1) RAID 5 (3+1) RAID 5 (8+1) Cost per Useable TB

  30. 1st with support for queue depth throttling ESX3.5 Update 4 • VMware ESX 3.5 Update 4 introduces an adaptive queue depth algorithm that adjusts the LUN queue depth in the VMkernel I/O stack. • This algorithm is activated when the storage array indicates I/O congestion by returning a BUSY or QUEUE FULL status. • When congestion is detected, VMkernel throttles the LUN queue depth. • VMkernel attempts to gradually restore the queue depth when congestion conditions subside. • By default, this algorithm is disabled. To enable it see: http://kb.vmware.com/selfservice/documentLink.do?externalID=1008113

  31. 3PAR Benefits for VMware Deployments Summary • Provision storage in seconds • - provision “once and walk away” • More VM’s can be consolidated per ESX Server, and VMware application service levels are higher and more predictable - 3PAR’s unique architecture stripes volumes widely across all resources • - Consolidation with server virtualization puts burden on memory and requires high performance disk I/O • Thin Provisioning allows you to support a VMware deployment with fewer arrays • - present large storage volumes without dedicating all the space • Dynamic Optimization flexibility • - change RAID levels and disk types on the fly without any disruption 3PAR reduces storage costs = more money for virtualization deployment
