While there are already PCIe-based implementations of SSD technology, the Working Group aims to make the technology a standard that can be applied across all server and storage devices.
To that end, the Working Group is proposing a new type of connector which will work with SAS, SATA, and PCIe 3 so that customers will not need multiple connectors, said Gary Kotzur, technology strategist for Dell.
The coalition is also proposing that the drives use the standard 2.5-inch drive form factor for the new PCIe SSDs, and support hot plug capability to ensure customers get high-availability and servicing ease, Kotzur said.
The standardization of PCIe SSDs should result in an increase in storage performance because of the low latency provided by PCIe technology, Kotzur said. That low latency comes from the fact that PCIe allows direct connection to the storage, whereas other storage technologies require bridging chips.
In addition to lower latency, PCIe SSDs should also eventually feature lower costs and higher reliability than current SSDs because of the lower component count, he said.
