Configuration rules
The 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
(Continuous Access EVA only) 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 Continuous Access EVA (see
“Continuous Access XP” on page 335“EVA storage system rules” on page 308) and XP Continuous
Access (see. “Continuous Access XP” on page 335).
• 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. See the HP StorageWorks IP Distance Gateway
user guide for performance-tuning information based on the link speed and delay.
