2003 (32-bit) Installation and Configuration Guide
Figure 54: Two-Cluster Fibre Channel Configuration
The Configuration in Figure 54 features the following attributes:
■ Two Windows NT/Windows 2000/Windows Server 2003 (32-bit) Clusters
(MSCS)
■ Two Fibre Channel Loops
■ Dual-redundant HSG80 RAID controllers operating in transparent failover
mode
■ Up to 84 UltraSCSI drives with optional expansion enclosures
■ Up to 128 LUNs total. 64LUNs per cluster with 2 active controller host ports
The configuration in Figure 55 builds on the previous Windows NT/Windows
2000/Windows Server 2003 (32-bit) cluster configuration by adding a redundant
I/O path from each server to the Enterprise & Modular Storage RAID Array. This
configuration requires Secure Path software and changing the Enterprise &
Modular Storage RAID Array to run in multiple-bus failover mode. This
configuration significantly improves I/O performance by utilizing all HSG80 host
ports. Secure Path also gives you the added benefits of load balancing your
storage and eliminates the I/O bus as a single point of failure.
Note: Refer to the Secure Path documentation for detail instructions on configuring
Windows NT/Windows 2000/Windows Server 2003 (32-bit) clusters with Secure
Path.
