"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."
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, the ioDrive Duo has more than enough bandwidth to obtain leading performance from a single card. The ioDrive Duo can sustain 1.5 Gbytes/sec of read bandwidth and nearly 200,000 read IOPS. Its performance metrics are as follows:
- Sustained read bandwidth: 1500 MB/sec (32k packet size)
- Sustained write bandwidth: 1400 MB/sec (32k packet size)
- Read IOPS: 186,000 (4k packet size)
- Write IOPS: 167,000 (4k packet size)
The ioDrive Duo also offers solid-state protection for data integrity and reliability with triple redundancy for a single storage component.
- Multi-bit error detection and correction
- Patent-pending Flashback protection, offering chip-level N+1 redundancy and on-board self-healing so that no servicing is required
- 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 of 160GB, 320GB and 640GB. A 1.28B version will be available in the second half of 2009.
The ioDrive Duo will be available in April 2009.
