6 Release Notes – Data Replication Manager HSG80 ACS Version 8.6-4P
Switch Configurations
There is a restriction in DRM design options when building Fibre Channel fabrics
using Compaq Fibre Channel switches by Brocade and running the currently
supported Brocade switch firmware and ACS Version 8.6-4P. These limitations are as
follows:
• A maximum of 7 hops from server to storage controller
(HBA to controller port 1),
• A maximum of 7 hops from initiator storage controller to target storage controller
(port 2 to port 2),
• A maximum of 20 switches per fabric, split between the two sites.
There are several unique cases that are supported but do not follow this rule. For
example, in a basic DRM configuration, there is only one switch per fabric at each of
the two sites. This configuration is supported. Also, the optional entry-level DRM
solutions offered in Chapter 5 of the SANworks by Compaq Data Replication
Manager HSG80 ACS Version 8.6-4P Configuration Guide do not follow this rule.
The Compaq StorageWorks Heterogeneous Open SAN Design Reference Guide is
available on the web at:
