PERATING IN
iSCSI networks use Gigabit Ethernet protocols for managing the transfer of
data across the network. This section provides information about
configuring your network to provide optimal library performance.

Best Practices for IP SANs

IP SANs should be based on Gigabit Ethernet 1000BaseT network
topography. Since backups and storage networks create a good deal of
traffic, a dedicated subnet should be utilized. IP SANs should not be
sharing bandwidth with regular user LAN traffic.

Best Practices for iSCSI

The best performance with iSCSI is achieved by setting the iSCSI
parameters to the following state:
The parameters below can be set to the maximum values listed below:
Best performance is achieved by setting these values to their maximum
value.
Supported Optical SFPs
Spectra Logic recommends using quad-rate SFPs with all E-QIPs.
Supported Copper SFPs
Copper RJ-45 SFPs are supported on the G3 E-QIP. Copper SFPs are
designed for use with Gigabit Ethernet connections only and are not for use
with Fibre Channel connections.
The minimum cable requirements when using the copper SFPs is CAT5e.
CAT6 cable is highly recommended for distances greater than 10 feet.
