The HP VMA-series Memory Arrays (VMA) are scalable, solid state storage systems utilizing RAID protected Flash memory to optimize online transaction processing (OLTP) for database applications, with additional opportunities for data warehouse and business intelligence workloads. The initial HP VMA3200 solution provides from 5TB to 10TB capacity per unit and eliminates the seek-bound limitations of disk storage and delivers significant application performance benefits over traditional storage systems with hundreds of hard drives (HDDs) or small capacities of solid state drives (SSDs). With the high capacities afforded by this product, customers can easily and quickly place entire databases into solid state memory and achieve very high IOPS performance with extremely low latency. Database solutions comprised of HP servers and HP VMA-series Memory Arrays provide capacity and performance besting competition costing many times the price.

Key Features

Capacity

  • Up to 10TB per 3U memory array
  • Dedicate up to 8 memory arrays (80TB of storage) to a single server via high-speed PCIe links
  • Share storage among many servers via Fibre Channel SAN connection
  • Scalable capacities up to petabytes of storage – capable of holding an entire database without need for special designs or architectures

Performance

  • Each HP VMA3200 with Single Layer Cell (SLC) NAND Flash delivers sustained DRAM-like performance that is 50 times faster than a similar size HDD array
  • Minimize latency and maximize IOPS (I/O operations per second)
  • Achieve sustained performance with on-board write wear leveling

Availability

  • RAID protected, hot-plug memory modules with 4 + 1 parity and memory sparing
  • Redundant power supplies and fans, standard
  • External design makes it easy to reconnect storage to different server hosts

Simplicity

  • Simple setup and administration
  • Memory arrays can be configured for PCIe direct connect or via Fibre Channel for SAN connectivity
  • 3U chassis fits into standard racks

    Answers

    Q1. Can the VMA-series Memory Array be used with all ProLiant products?
    A1. No, the VMA-series Memory Array is only supported with the ProLiant DL980 G7 server. Other solid state options such as HP IO Accelerators and HP Solid State Disks are available for ProLiant servers.
    Q2. How many VMA-series memory arrays can I attach to a single DL980 using the PCIe-direct method?
    A2. HP has validated eight arrays attached to one DL980 G7. Each array requires a PCIe Pass Thru card be installed in the DL980 G7, and a dedicated cable between each PCIe Pass Thru card and each array.
    Q3. Can a mix of VMA-series Memory Arrays models be simultaneously connected to one DL980 G7 server (using the PCIe-direct method) or to one SAN gateway?
    A3. Yes. Arrays do not have to be identical. Any combination of models is allowed.
    Q4. Is there a PCIe-direct connect option for Integrity servers?
    A4. Not at this time.
    Q5. What is the configuration of the SAN Gateway?
    A5. The SAN Gateway is an appliance product based on a ProLiant DL380 G7 with vShare software factory installed. Up to two VMA arrays can be connected to one SAN Gateway. Each VMA-series memory array requires one PCIe Pass-thru card installed in the SAN Gateway, and one PCIe cable connecting the SAN Gateway to the VMA array. The SAN Gateway includes redundant power supplies and fans and two 8Gb dual-port Fibre Channel HBA cards. Up to two additional 8Gb dual port FC HBAs can be ordered/installed in the SAN Gateway for additional SAN connectivity. No additional software may be installed on the SAN Gateway.
    Q6. Can two DL980 G7 servers share one VMA-series Memory Array?
    A6. Yes, multiple servers can share the same VMA-series Memory Arrays when the memory arrays are connected via the SAN Gateway for SAN attach. The PCIe-direct connect option cannot attach a VMA to more than one host server.
