Flash storage specialist Fusion-io has launched the latest generation of its ioMemory flash accelerator product line, offering double the capacity at up to 6.4TB per card, plus increased performance through better optimisation of the way software accesses flash.
Available immediately, Fusion-io's Atomic Series is the third generation of its ioMemory platform for accelerating storage performance for applications, and is the first product of its kind to fit the latest generation 19/20nm Nand flash silicon technology, according to the firm.
The new cards, which slot into a PCI Express slot in a server as with Fusion-io's existing products, can be fitted with up to 6.4TB of capacity, double that of the previous generation.
However, the most significant features are enhancements in flash-aware acceleration to improve overall performance, according to Fusion-io chief strategy officer Gary Smerdon.
"We've been working with the software providers, the ISVs, to do more optimisations from the software to get even better application performance," Smerdon told V3.
Typically, this involves getting key applications to change the way they perform write operations when ioMemory is detected in the system, such as the Atomic Writes feature Fusion-io has already seen added into MySQL.
Smerdon likened this to the way software will often be written to make use of new instructions in the processor.
"Applications will go ‘OK, those instructions are there, I'll take advantage of those'. This is similar, in that software generally assumes it just has a traditional storage system that communicates through a SCSI protocol. That protocol is 30 years old and it was never designed with anything other than hard drives in mind," he said.
With Atomic Series, the firm has worked with other vendors to broaden this support, including Microsoft's SQL Server.
Initially, the Atomic Series is split into two separate lines – the ioMemory PX600 and the ioMemory SX300 – with different performance characteristics.
The PX is focused more on performance, for environments involving high write workloads, according to Smerdon, while the SX is for scale-out environments where higher capacity is required.
"The performance is a bit below that of the PX, but still higher than our current high-end products, and we've brought the power consumption down to 21W," he said. This should deliver significant savings when multiplied across a room full of servers, he added.
The PX line comprises models with 1TB, 1.3TB, 2.6TB and 5.2TB capacities, with performance up to 375,000 random write input/output operations per second (IOPS).
The SX line has capacities of 1.25TB, 1.6TB, 3.2TB and 6.4TB, with performance up to 300,000 random write IOPS.
