IO Accelerator
Hard Drive Recovery - IO Accelerator
The HP StorageWorks IO Accelerator (IO Accelerator) is a solid-state drive designed for HP’s BladeSystem c-Class servers. Introduced by HP in March 2009, the IO Accelerator is offered in mezzanine card form factor. The IO Accelerator technology is derived from a start-up firm Fusion-io. With this product, HP becomes the first company to create a product based on Fusion-io’s ioMemory architecture, and also the first to make it available to blade servers. The IO Accelerator is functionally identical to the ioDrive, and shares the same performance characteristics.
Important features
IO Accelerator features an adapter that connects to the blade server using a PCI Express x4 link. It offers bandwidth up to 800 MB/s and latency as low as 50 microseconds. This power-efficient model uses less than 9 watts. Because IO Accelerator is a Type-1 mezzanine card, user can install up to 2 in a half-height blade server such as the BL460c, and up to 3 can be installed in a full-height blade server like the BL685c.
The IO Accelerator is initially offered in capacities of 80GB, 160GB, and 320GB. The 320GB model uses MLC NAND, whereas the other two models use SLC NAND. The adapter combines NAND flash memory with a custom controller chip that interfaces directly to the PCI Express fabric of the server. The card has 25 channels of NAND Flash that are accessed in parallel.
The IO Accelerator currently cannot be used to boot the server. Drivers are only available for Linux and Windows. These drivers work with only 64-bit kernels (x86-64); they do not support 32-bit kernels.
