AA–RHH6B–TE
Or Maximum Storage Capacity,
Up to 2 Storage Systems (6 storage ports/3 Active, 3 Standby) and 2 Servers
[8 – 2 server ports = 6 storage ports]
•
All HSG80 array controllers configured in Transparent Failover Mode
•
EBS Integration Supported
SAN Configuration 1 Fabric Rules
•
Total Switches = 1, 16-port or 8-port
•
Maximum Switch Hops (nominal) = 0
•
Maximum Switch Hops (worst case )= 0
•
Maximum Distances
Up to 500 meters per FC cable segment, 1 km total server to storage using 50 micron multi-
mode fibre optic cable. Refer to general Fabric rules for other cable types
SAN Configuration 1 Notes
•
When configured with greater than 4 Windows NT Servers per active controller host port,
classified as an “NT Extended Configuration” (refer to the StorageWorks Windows NT Platform
Kit FC Software Setup Utility)
•
For servers accessing controller host port 1 use LUN number and offset values in the range of 0 –
99, for controller host port 2 use number and offset values in the range 100 -199
•
Performance considerations, assuming relatively equal server load:
If using a single storage system, for balanced performance across all servers configure half of
the servers on each of the controller port pairs. If using multiple storage systems configure an
equal number of servers on each storage system.
The recommended maximum number of controller host ports configured per FC HBA is 2 for
high bandwidth applications and 4 for high throughput applications.
