Storage Controllers; Table 12. Raid Controller Feature Support - Dell PowerEdge M820 Technical Manual

Express Flash drives
Express Flash drives use PCIe and SSD technologies to provide performance, scalability and optimal
serviceability. Accelerated performance with high IOPs is made possible without requiring processor
resources or capturing DRAM. Also, Express Flash drives use a standardized, 2.5-inch hot-plug form
factor, which allows a common management process for all drives.
The PowerEdge M820 has an option to support up to two Express Flash PCIe SSD drives with the
PCIe SSD backplane configuration. This backplane configuration may be selected at purchase, but
may not be upgraded later.
