.Sh DESCRIPTION
|
||||
NVM Express (NVMe) is a storage protocol standard, for SSDs and other
|
||||
high-speed storage devices over PCI Express.
|
||||
.Sh EXAMPLES
|
||||
.Dl nvmecontrol devlist
|
||||
.Pp
|
||||
Display a list of NVMe controllers and namespaces along with their device nodes.
|
||||
.Dl nvmecontrol identify nvme0
|
||||
.Pp
|
||||
Display a human-readable summary of the nvme0 IDENTIFY_CONTROLLER data.
|
||||
.Pp
|
||||
.Dl nvmecontrol identify -x -v nvme0ns1
|
||||
.Pp
|
||||
Display a hexadecimal dump of the nvme0 IDENTIFY_NAMESPACE data for namespace
|
||||
1.
|
||||
.Pp
|
||||
.Dl nvmecontrol perftest -n 32 -o read -s 512 -t 30 nvme0ns1
|
||||
.Pp
|
||||
Run a performance test on nvme0ns1 using 32 kernel threads for 30 seconds. Each
|
||||
thread will issue a single 512 byte read command. Results are printed to
|
||||
stdout when 30 seconds expires.
