    Business Drivers for Server Virtualization
    CAPEX savings is the #1 driver for Server Virtualization
    • 40% of users cite CAPEX savings as their #1 driver
    Easily quantifiable OPEX is next on the list, followed by Flexibility and DR
    Users on average have virtualized 35% of server workloads
    More than 75% of respondents plan to virtualize at least 2/3 of their workloads within next few years
    Server Virtualization will continue to be a technology driver over the next few years

  8. 18. Virtualization Reality: Memory Limitations Make Storage A Precious ESX Resource
    ESX techniques for handling memory over-commitment:
    Page sharing
    Ballooning
    Swapping
    Random ESX I/O stresses disk performance
    Traditional storage with large caches not effective
    VM performance gated by disk IOPs and storage capacity

  12. 22. 3PAR Wide Striping enables higher VM Density
    3PAR Wide Striping
    • Spreads volumes across all disks
    • 23. Delivers predictable performance even at full capacities
    • 24. Allows a VMDK to be striped across all disks without capacity wastage
    Benefits for VMware
    • Higher and more predictable service levels in VMware environments
    • 25. More VMware ESX servers to be consolidated per array
    • 26. Double #VMs per physical server

  13. 27. 3PAR Gen3 ASIC is key for superior mixed workload support
    • High speed, low latency interconnect between the controller nodes.
    • 28. Responsible for moving all data.Leaves CPUs to do what they do best - compute.Mixed workload built in.
    • 29. Mirrors writes in the HW
    • 30. RAID Calculations in the HW
    • 31. Zero Detect -Thin built-in to the HW

  15. 32. 3PAR Integration with VMware Adaptive Queue Depth Algorithm for Automated IO Queue Management
    New QoS feature in VMware vSphere 4 and ESX 3.5 U4
    • Developed by VMware in collaboration with 3PAR
    • 33. Dynamically adjusts the number of queued I/O on a LUN
    • 34. Helps recover gracefully from I/O congestion at the port level
    3PAR storage is qualified with VMware Adaptive Queue Depth
    Allows customers to consolidate more VMs per ESX server since I/O traffic levels are regulated dynamically
  16. 35. Greater Scalability and Agility: Hardware Assisted Locking (ATS)
    • New feature in VMware vSphere 4.1
    • 36. Improved VM density and scalability
    Greater agility while performing common actions

    • 37. Powering on/off a VM
    3PAR Unique advantage
    • Data comparison operation is 10x faster
    • 38. Performed in 3PAR ASIC vs. Array controller CPU
    Benefit seen in consolidated environment and Hosted Service Providers
  17. 39. Greater Agility for Enterprise and Cloud Datacenters: Fast Copy (XCOPY)
    • New feature in VMware vSphere 4.1
    Greater agility while performing common actions
    • 2x better performance with VM Cloning
    3PAR Unique advantage
    • Only written data will be cloned with EZT VMDKs
    Benefit seen in almost all VMware vSphere deployments

  19. 50. Complexity of Traditional Storage
    With traditional storage, provisioning is complex, slow and labor-intensive
    Requires careful and time-intensive upfront planning
    Results in brittle configuration
    Requires many more administration resources
  20. 51. Simplified Storage and Server Provisioning
    3PAR Rapid Provisioning
    Seconds to provision storage with no pre-planning
    Self-configuring and auto load-balanced storage volumes
    Labor-intensive and careful planning eliminated
    Benefits
    Minutes to provision virtual servers
    Dramatic reduction in storage administration
  21. 52. Clustered environments add additional complexity to storage provisioning
    VMware clusters create new storage management challenges
    1 cluster of 5 hosts and 10 volumes,requires 50 provisioning actions on most traditional arrays!
    • At 10 min/action: More than 1 day!
    • 53. Error-prone
    VMware clusters are dynamic resources subject to growth and frequent change
  22. 54. 3PAR Autonomic Groups eliminates repetitive error-prone tasks
    3PAR Autonomic Groups
    • Simplifies and automates volume provisioning in a single command
    Exports a group of volumes to a host or cluster of hosts
    • Automa
