HP and SanDisk join to create storage-class memory solutions

HP and SanDisk have announced a partnership which will see the two co-develop storage-class memory (SCM) solutions pegged to replace DRAM and NAND flash.

The two firms are designing the technologies for the enterprise cloud and data centre markets, for infrastructures based on HP’s memristor and SanDisk’s Resistive Random Access Memory (ReRam).

The companies claim that the proposed non-volatile memory will be up to 1,000 times faster and 1,000 times more durable than flash storage. Siva Sivaram, executive VP of memory at SanDisk also advised that the technology will provide cost benefits over DRAM solutions, improving on power, density and persistence.

The SCM technology is intended to allow systems to employ ‘tens of terabytes’ (TB) of memory per server node, required by applications such as in-memory databases, real-time big data analytics, and transactional and high-performance computing.

The storage-class offering will be made available as enterprise SAS, SATA and PCIe products that can replace DRAM, and support NAND flash for high tier applications.

DRAM-replacement has become a hot area for companies over the past couple of years, with extensive research projects into finding cheaper, non-volatile alternatives that offer more endurance.

Earlier this year, Intel and Micron announced their new 3D XPoint memory – a ‘Simple. Stackable. Transistor-less’ architecture which creates “an innovative cross-point structure consisting of individual wires,” allowing for the address of individual memory cells by selecting two wires perpendicular to each other. The technology offers much higher performance than flash – NAND’s latency is measured in 10s of micro-seconds, whereas 3D XPoint latency is recorded in 10s of nanoseconds.

Martin Fink, executive VP and HP CTO highlighted the need for innovative memory solutions to keep up with the ‘onslaught of data facing enterprises.’ ‘We are excited to be working with SanDisk as they share an understanding of the significance of this challenge’ he explained, concluding that the HP-SanDisk vision believes the solution lies within ‘memory-driven computing.’
