• When using FCIP, the TCP send buffers must be set to 4,096 K on all FCIP profiles on both
the source and destination sites. One exception is a solution using a link less than OC3 (155
Mb/s), in which case buffers must be set to 8,192 K (tcp send-buffer-size 8192).
H-series switch configuration
H-series switches only support either the HP IP Distance Gateway or the MPX200 Multifunction
Router. The FC-to-IP gateways should be same model and software version on each side of the IP
network in the fabric.
NOTE: H-series FC switches are only supported with XCS 09534000 or later and the HP SCSI-FCP
protocol. For the latest information about supported firmware, see the P6000/EVA Array Streams
and the H-series FC Switch Connectivity Stream on the HP Single Point of Connectivity Knowledge
(SPOCK) website at http://www.hp.com/storage/spock.
You must sign up for an HP Passport to enable access.
M-series switch configuration
Both HP-FC protocol and HP SCSI-FCP protocol can be used with M-series switches. If the M-series
switch is installed in an environment with other model switches (for example, B-series), follow the
configuration settings for the other (non-M-series) switch.

NOTE: The following configuration must be used in an HP P6000 Continuous Access environment
for all Fibre Channel switches in the path from the source array to the destination array.
The Reroute Delay (in-order delivery) must be enabled on all M-series switches (rerouteDelay

Verifying cabling
Verify that the cabling between the arrays and Fibre Channel switches meets remote replication
requirements. The supported cabling scheme depends on the array controller hardware and software
features, as shown in Figure 17 (page 55) through Figure 19 (page 55). In mixed array
configurations, use the cabling scheme specific to each controller. For a description of all cabling
options, as well as best practices for cabling, see the HP SAN Design Reference Guide.
NOTE:
• For low-bandwidth intersite links, HP recommends using separate array ports for host I/O and
replication I/O.
• When connecting the array, the even-numbered controller ports should be connected to one
fabric, and the odd-numbered controller ports should be connected to a different fabric.
• On arrays running VCS 3.xxx, straight or cross-cabled connections are supported with HP
P6000 Continuous Access.
Figure 17 (page 55) shows the standard cabling scheme for remote replication on arrays with
two-port controllers. The even-numbered ports on each controller are connected to one fabric and
the odd-numbered ports on each controller are connected to the other fabric. Figure 18 (page 55)
shows the same connections for the EVA4400 single-enclosure controllers.
