HP is introducing a new top-end 3PAR StoreServ 20000 all-flash array family, lowering flash storage costs, federating systems, and flash-optimising its software.

The ASIC-accelerated StoreServ product family now consists of:

  • 20850 high-end and all-flash array
  • 20800 converged (disk/flash) array
  • 10000 converged (flash/disk) arrays
  • 7450 all-flash array
  • 7440 converged (flash/disk) array
  • 7200 all-flash starter array

Effectively, view a 20800 as a 20850 that can have disks as well; the 20800 being a flash-only orderable system or SKU that meets Gartner AFA reporting requirements.

HP also has its storage range-topping XP7 (P9500) array, OEM’d from Hitachi and based on its VSP G1000 technology. It has seven nines availability and is positioned for mission-critical workloads; the 7450 has six nines availability. The 20000 is targeted to achieve seven nines availability.

The StoreServ 20850 features:

  • Between two and eight controllers (7450 has between two and four)
  • Up to 3.6TB cache
  • From four to 1,024 SSDs
  • From 1.9TB to 3,932TB raw capacity
  • 280TB of usable capacity in a 2U enclosure
  • 5.5PB usable on a single floor tile
  • More than 3.2 million IOPS (8K random read) - 7450 does >900,000
  • Over 75GB/sec of sustained throughput

It can use 480GB, 920GB, 1.92TB, and 3.84TB SSDS.

The accompanying 20800 features what HP calls a flash-first design, with:

  • 2 to 8 controllers
  • Up to 1.8TB on-node cache and a total of 33.8TB including flash cache
  • Up to 1,920 total drives - HDDs and SSDs can be mixed in any combination with a maximum of 1,024 SSDs
  • From 1.92TB to 6PB raw capacity
  • 280TB of usable capacity in a 2U enclosure
  • 5.5PB usable on a single floor tile
  • More than 3.2 million IOPS (8K random read) - 7450 does >900,000
  • Over 75GB/sec of sustained throughput

The 20800 can use 600GB 15K, 600GB 10K, 1.2TB 10K and 6TB 7.2K disk drives. The supported SSD types are the same as for the 20850.

It scales out to 15PB of usable (after dedupe and compression) capacity.
