Nimbus Data has announced its scale-out ExaFlash all-flash array at the Flash Memory Summit, with four models ranging up to 4.5PB raw capacity in 4U. Nimbus' overall claims for ExaFlash start from scale and rackspace density and ultimately encompass "empowering humankind's innovation" for decades:
Nimbus Data's ExaFlash Platform is a historic achievement that will reshape the storage and data center industries. It offers unprecedented scale (from terabytes to exabytes), record-smashing efficiency (95 per cent lower power and 50x greater density than existing all-flash arrays), and a breakthrough price point (a fraction of the cost of existing all-flash arrays). This is a game-changer in every sense that will leave competitors gasping and customers beaming. ExaFlash brings the all-flash data center dream to reality and will help empower humankind's innovation for decades to come.
With ExaFlash, Isakovich says data flow is decoupled from metadata and no network or data movement exists between the fully redundant arrays, which redundancy eliminates costly data mirroring. Multiple protocols can operate simultaneously, eliminating islands of storage resource per protocol.
MLC flash is used in all four models. Nimbus says it has a patented Parallel Memory Architecture non-blocking design and a hardware-offload engine reduces CPU power usage by 90 per cent.
|Raw Capacity||50TB – 100TB||125TB - 1PB||1.5PB - 3PB||4.5PB|

|Raw Per-GB Pricing (with HW+SW)||$0.95||$0.95||$0.65||$0.50|
Available connectivity options include 16Gbit/s FC, 40GbitE, and 56Gbit/s InfiniBand for the A-series. The other three systems get 32Gbit/s FC, 100GbitE and 100Gbit/s InfiniBand. All four models run the ExaFlash OS.
This includes block (iSCSI, FCP, SRP, iSER) and file (NFS, SMB, CIFS) protocols, with object coming next year. There is inline, variable deduplication and compression to increase effective capacity, with 3:1 data reduction quoted in material we have seen.
There is single pane of glass admin plus API-driven admin. Storage is thin-provisioned, and there are monitoring, snapshot, cloning and replication services.
The 2U A-Series looks the same as a 2U Gemini array (PDF) with 24 front-mount SSD slots in three groups of eight. That has a maximum 48TB raw capacity. We don't know how many drive slots there are in the B-, C- and D-Series, as the bezels cover any front-mounted slot details.
