Non-Volatile Memory Express
Non-Volatile Memory Express (NVMe) is a standardized, high-performance host controller interface and a storage protocol for
communicating with non-volatile memory storage devices over the peripheral component interconnect express (PCIe) interface
standard. The PERC 11 controller supports up to 8 direct-attach NVMe drives. The PERC 11 controller is a PCIe endpoint to
the host, a PowerEdge server, and configured as a PCIe root complex for downstream PCIe NVMe devices connected to the
controller.
NOTE:
The NVMe drive on the PERC 11 controller shows up as a SCSI disk in the operating system, and the NVMe
command line interface will not work for the attached NVMe drives.
Conditions under which a PERC supports an NVMe drive
● In NVMe devices the namespace identifier (NSID) with ID 1, which is (NSID=1) must be present.
● In NVMe devices with multiple namespace(s), you can use the drive capacity of the namespace with NSID=1.
● The namespace with NSID=1 must be formatted without protection information and cannot have the metadata enabled.
● PERC supports 512-bytes or 4 KB sector disk drives for NVMe devices.
