Chelsio T5 iSCSI PDU Offload Target with SCST support for Linux
testing network performance.
SYNC specifies that the device
will function in the write-through
mode (i.e., the data will be flushed
to the device before the response
is returned to the initiator).
NOTE: SYNC is only applicable
with FILE mode.
RO specifies the device as a read-
only device.
FILE specifies this device should
be accessed via the kernel‟s VFS
layer. This mode is the most
versatile, and it is the default
mode in the cases where there is
no mode specified.
BLK specifies this device should
be accessed via the kernel‟s block
layer. This mode is suitable for
high-speed storage device such
as RAID Controllers.
MEM specifies this device should
be created as a RAM Disk.
size=xMB is used with "MEM", to
specify the RamDisk size. If not
specified, the default RamDisk
size is 16MB (16 Megabytes). The
minimum value of x is 1 (1MB)
and the maximum value is limited
by system memory.
SN is a 16 character unique value.
ID is a 24 character unique value.
WWN is a 16 character unique
value.
SCST specifies the device using
SCST backend. All SCST LUNs
are treated as pass-through by
chiscsi. The incoming
requests will be passed to SCST
and SCSI responses from SCST
will be sent back to
originators.
It is recommended when using a
multipath aware initiator,
optional ID (short form for SCSI
ID), SN and WWN values should
be set manually for
TargetDevice. These values will
be returned in Inquiry response
(VPD 0x83).
