Two-port 10-Gb/s optical or active Twinax iSCSI I/O module
The two-port 10-Gb/s optical or active Twinax
10
iSCSI I/O module comes with two
optical or active twisted pair ports, one power/fault LED, and a link and activity LED
for each port (
). The optical ports on this I/O module can interface at speeds
of 10 Gb/s for iSCSI (Internet Small Computer System Interface) networks
11
. The
two-port 10-Gb/s optical I/O module uses the SFP+ transceiver module (see the
section describing the SFP+
“Four-port 8-Gb/s FC I/O module” on page 41
for more
information about the SFP+ modules). The two-port 10-Gb/s optical I/O module
uses iSCSI protocol, hence the required SFP+ transceiver module (for part number,
see the
VNX5300 Parts Guide
).

10. The two-port 10-Gb/s I/O module can also use active twinaxial (Twinax) cables. Twinax is a
type of cable similar to coax, but with two inner conductors instead of one. These cables will
be supplied in lieu of the SFP+ when so ordered.
11. iSCSI is a protocol for sending SCSI packets over TCP/IP networks.
