Kaminario upgrades K2 all-flash to Gen6 with new controller CPUs

All-flash array maker puts Intel Broadwell processors into its controllers to boost I/O performance and increases capacity to multi-petabytes with 3D TLC flash drives

All-flash pioneer Kaminario has launched the sixth generation of its all-solid state arrays, with a 2x performance increase based on controller upgrades with Intel Broadwell CPUs.

With 4TB 3D TLC flash drives, a Gen6 Kaminario K-Block now scales to 1PB – an increase of 5x over the previous generation.

The K2 architecture comprises modular K-Blocks that include an active-active controller pair and between one and four drive shelves that each accommodate 24 flash drives. Rack space-wise, that translates to 4U to 26U and drive types available are multi-level cell (MLC) and/or TLC drives.

Kaminario uses commodity hardware and its Vision OS operating system to build its all-flash product. It spreads writes around and has a write-buffer to prevent hotspots. It claims a seven-year flash lifespan.

Kaminario arrays provide block access (Fibre Channel and iSCSI) and have thin provisioning, inline data deduplication and compression.

Specs-wise, in the new Gen6 arrays, one K-Block offers 30TB to 1PB of effective capacity with 370K IOPS and 6.2GBps of throughput; a two K-Block configuration provides 60TB to 2PB with 740K IOPS and 12.4GBps of throughput; three K-Blocks give 90TB to 3PB 1.1M IOPS and 6GBps of throughput; and four K-Blocks give 120TB to 4PB of effective capacity with 1.5M IOPS and 25GBps of throughput. Latency is the same for all configurations, at 0.35ms.

Kaminario customers can add Gen6 modules to existing Gen5 implementations non-disruptively.

Kaminario arrays have built-in compression with a guaranteed ratio of 4:1 achievable. The company says it will provide free capacity to customers that fail to gain 4:1 from its hardware.

Other key upgrades include the provision of NVMe slots and the ability to take NVDIMM memory modules. Both allow for the addition of media via speedier interfaces than are used by most drives in K2 modules, which probably means they are suited to cache. Also, 32Gbps Fibre Channel can be supported.
