K2 Ethernet switch description
K2 Ethernet switch description
The K2 Ethernet switch provides the primary network fabric of the K2 Storage
System. The switch supports Gigabit Ethernet connections, which provides the
bandwidth required for the iSCSI media traffic.
The recommended K2 Ethernet switch is a HP ProCurve Switch 3400cl-24G. This
switch has been tested and qualified for the K2 Storage System. The switch is a
store-and-forward device offering low latency for high-speed networking. In addition,
the switch offers full network management capabilities.
You must use the HP ProCurve switch for iSCSI traffic. You can use a Cisco switch,
such as the Cisco Catalyst 3750 Gigabit Ethernet switch, for control and FTP/
streaming traffic, if required by your site.
Refer to the manuals that you receive with the switch for more information.
Refer to the installation chapters earlier in this manual for connection and
configuration instructions.
