Fusion-io Shows Next Generation ioMemory Products

By Stuart J. Johnston

The new ioDrive2 and ioDrive2 Duo feature faster speeds, higher capacities, and self-healing capabilities.

Fusion-io debuted its next generation of ioMemory products Monday at Oracle OpenWorld, trotting out NAND Flash-based server cards that are faster and hold more capacity than their predecessors.

The new ioDrive2 and ioDrive2 Duo from Fusion-io (NYSE: FIO) also add higher reliability to the company's line of memory products and accompanying software that is designed to "decentralize" memory from an appliance-based approach like many competitors use to one that locates the memory in the server that's doing the actual database processing, according to Fusion-io officials.

"[Putting the memory in an appliance] is like sucking an elephant through a straw," David Flynn, CEO and chairman of Fusion-io," told

Additionally, the new ioMemories also support what the company calls "Adaptive FlashBack" -- an intelligent self-healing capability that can detect failed NAND chips and "heal around" them. What's more, Adaptive Flashback can deal with multiple chip failures.

"The card can have multiple failures and it just keeps working -- it doesn't stutter," Flynn said.

Among the new features in the ioDrive2 and ioDrive2 Duo are the ability to hold as much as 2.4 TB of capacity in a single card, Flynn added.

The ioDrive 2 ranges in capacity from 365 GB of multi-level cell (MLC) NAND Flash ioMemory2 to 1.2 TB of MLC, and features up to 1.3 GB per second (GBps) of write bandwidth and 1.2 GBps of read bandwidth, according to Fusion-io statements.

Meanwhile, the ioDrive2 Duo, which can hold 1.2 TB of single-level cell (SLC) Flash ioMemory2 or 2.4 TB of MLC, features up to 3 GBs of write bandwidth and 2.6 GBs of read bandwidth.

Both products provide system level integration with the Fusion-io VSL (Virtual Storage Layer) 3.0 software subsystem, and support Windows, Linux, OSX, Solaris x86, ESXi 5.0 and HP-UX, the statements said.

MLC versions of ioDrive2 and ioDrive2 Duo will go on sale in November, followed by SLC versions. They start at $5,950.
