Figure 78 Network using FCIP
Compression on FCIP tunnels
Data compression can be enabled or disabled on FCIP tunnels. The default setting is to disable
compression.
Traffic shaping
Traffic can be shaped by establishing a rate limit per tunnel. A committed rate guarantees a fixed amount
of bandwidth and is assigned to a tunnel. The committed rate setting ensures that an FCIP tunnel operates
at the specific fixed rate for FCIP traffic. The rest of the possible 1000 Mbps rate that a GE interface
provides is available to other tunnels created on this GE interface. If the committed rate is too small for the
amount of FCIP traffic, the FCIP tunnel is limited to that rate and performance may be affected. Total
bandwidth of all committed and uncommitted rate tunnels must not exceed 1000 Mbps. When allocating
committed rates to tunnels, do not allocate more bandwidth than the WAN can support or your FCIP tunnel
may not be stable.
FCIP services license
Most of the FCIP extension services described in this chapter require the B-Series High Performance
Extension over FCIP/FC license
. Use the licenseShow command to verify that the license is present on the
hardware used on both ends of the FCIP tunnel. For details on obtaining and installing licensed features,
see Chapter 1, ”Performing basic configuration tasks” on page 29.
Platforms that support SAN extension over IP
Fabric OS supports SAN extension between HP StorageWorks 400 Multi-Protocol Router and B-Series
Multi-Protocol Router Blades installed on an HP StorageWorks 4/256 SAN Director or an HP
StorageWorks DC SAN Backbone Director or HP StorageWorks DC04 SAN Director Switch
