So when Pure Storage calculates $/GB usable, we make some background assumptions:
All Pure Storage pricing examples are provided as HA, as this is a hard requirement for enterprise deployments Pure Storage HA doesn’t rely on “mirroring” two arrays, rather it is true active/active clustered controller HA (add HA by adding a controller, not doubling the array or all the flash) HA, RAID, metadata, and flash management have a combined overhead of 22% in the Pure Storage FlashArray and are included in our usable price (our RAID-3D is better than dual-parity, and can’t be set or adjusted, so this doesn’t vary from 22%) All the prices quoted here are preliminary, and will be finalized with our GA release
Pure Storage pricing is, in round numbers (varies slightly by model and configuration):
$/GB raw for a HA FlashArray is $20 / GB $/GB with HA and RAID is $25 / GB $/GB usable (including HA, RAID, and 5-to-1 data reduction) is $5.00 / GB $/GB usable (including HA, RAID, and 10-to-1 data reduction) is $2.50 / GB Note that our Beta customers have commonly seen 5-10x data reduction in database workloads, and 10-20x data reduction in virtualization workloads, all without sacrificing performance.
