Configuration rules
This section describes the configuration rules for using the mpx110 gateways for FCIP.
General configuration rules
Review the following general configuration rules:
• All mpx110 configurations require a minimum of two mpx110 gateways, one local and one
remote, connected through an IP network. These can be two mpx110s or one MPX200 with
an FCIP license and one mpx110, one local and one remote, connected through an IP network.
HP does not support FCIP connectivity between other gateway models.
• The mpx110 gateway is supported using FCIP extension with HP P6000 Continuous Access,
HP P9000 (XP) Continuous Access, and 3PAR Remote Copy. See “EVA storage system rules”
(page 282) and “HP P9000 (XP) Continuous Access” (page 304).
• Enable compression for IP fabrics with an RTT greater than or equal to 50 ms or a guaranteed
WAN bandwidth of less than or equal to 45 Mb/s. For performance-tuning information based
on the link speed and delay, see the HP StorageWorks IP Distance Gateway User Guide.
