HDS launches mid-market F Series all-flash arrays

Hitachi Data Systems launches the F Series, all-flash arrays aimed at mid-market customers that slot in below HDS's high-end G Series, plus a new 6.4TB high-capacity flash drive

Hitachi Data Systems (HDS) has launched the F Series, a mid-range family of all-flash arrays that form part of its VSP product line, along with a flash module, the FMD DC2, which doubles drive capacity to 6.4TB. 

The F Series has FMD DC2 modules as an option in the three 2U systems launched. The existing high-end G Series hybrid flash arrays can also use the new flash modules.

The three F Series models – the F400, F600 and F800 – have capacities of between 15TB and 256TB raw plus compression, but have controllers differentiated by central processing unit (CPU) and memory that provide 375,000 input/output operations per second (IOPS), 800,000 IOPS and 1.4 million IOPS per controller, and throughput of 11Gbps, 12Gbps and 24Gbps respectively.

Drive sizes available are 1.6TB, 3.2TB and 6.4TB.

The F Series arrays have inline compression, with no performance penalty, said product marketing director Bob Madaio, who added that the F Series arrays explicitly target mid-market customers and use cases and fit in the HDS range below the high-end G Series VSP arrays.

“It’s a push to the mid-market, for new customers and for new parts of current customers,” he said. We haven’t had a smooth go-to-market strategy for the smaller customer so these are different to the G Series. You can’t fit spinning disk HDDs to the F Series and that’s helped us to make these arrays cost effective.”

Local replication and cloning within F Series arrays is standard, but synchronous or asynchronous replication between sites comes at extra licensable cost, as does encryption.

Customers with both F and G series arrays can replicate between them as they both form part of HDS’s VSP range, which has storage virtualisation capability that allows it to create a pool of capacity from any supplier’s storage products.
