Table 164 (page 313) lists the network requirements for long-distance IP gateways that are supported
with HP P9000 (XP) Continuous Access.

Access
RequirementSpecification
Bandwidth
1
• Must be dedicated to the HP P9000 (XP) Continuous Access storage
replication function.
• The minimum IP bandwidth required for HP P9000 (XP) Continuous Access
is 16 Mb/s per path.
• When configuring multiple long-distance links, ensure all links provide equal
bandwidth and latency for maximum sustained aggregate performance. If
any single link has reduced performance or increased latency, all links will
be reduced to the lowest performing link, significantly lowering the aggregate
performance.
• There is no support for dynamic pacing of the gateway.

MTU of the IP network
2,348 bytes: B-series 400 MP Router, MP Router Blade
3,000 bytes: C-series MDS 9222i, 9216i, IPS-8, IPS-4, 14/2
Note: These MTU settings are the recommended maximum values when using
the respective FCIP products. You must ensure that the connected network
components support the same values for end-to-end connectivity at the stated
rates.
