Specifications
The mezzanine adapter connects to the blade server using a PCI Express ×4 link, uses less than 9 watts, has bandwidth up to 800 MB/s and latency as low as 50 microseconds.
The PCIe adapter connects to the server using a PCI Express Gen 1 ×4 link, Gen 1 ×8 link, or Gen 2 ×4 link, depending on model.
The IO Accelerator was initially offered in capacities of 80 GB, 160 GB, and 320 GB. The 320 GB model uses MLC NAND, whereas the other two models used SLC NAND. The 80 GB and 160 GB are now discontinued, and a new 640 GB model has been introduced. All current models use MLC NAND.
The PCIe IO Accelerator is now offered in 160 GB, 320 GB, 640 GB, and 1.28 TB capacities. It comes in two form factors: ioDrive or ioDrove Duo (two ioDrives on one PCIe card). The 160 GB is available in SLC NAND only, the 320 GB is available as either SLC Duo or MLC, and the 640 GB and 1.28 TB are both MLC Duo models.
Since the IO Accelerator is a Type-1 mezzanine card, the 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 PCIe IO Accelerator can be installed in most Proliant servers, and as many as 11 can be installed in one system (DL580).
