Fusion-io has announced the ioDrive Duo, which doubles the slot capacity of Fusion-io’s previous model PCI Express-based ioDrive storage solution. The new ioDrive Duo is the market’s fastest and most innovative server-based solid-state storage solution.
The company says performance for multiple ioDrive Duos scales linearly, allowing enterprise to scale performance to six gigabytes per-second (Gbytes/sec) of read bandwidth and over 500,000 read IOPS by using four ioDrive Duos.
This storage option is based on PCI Express x8 or PCI Express 2.0 x4 standards, which can sustain up to 20 gigabits per-second (Gbytes/sec) of raw throughput.
“Many database and system administrators are finding that SANs are too expensive and don’t meet performance, protection and capacity utilization expectations,” said David Flynn, CTO of Fusion-io. “This is why more and more application vendors are moving toward application-centric solid-state storage. The ioDrive Duo offers the enterprise the advantages of application-centric storage without application-specific programming.”
The ioDrive Duo offers triple redundancy for a single storage component, multi-bit error detection and correction, chip-level N+1 redundancy plus an optional RAID-1 mirroring between two ioMemory modules on the same ioDrive Duo, offering complete redundancy on a single PCIe card.
The ioDrive Duo comes in capacities from 160GB to 640GB. A 1.28TB unit is planned for the second half of 2009.
