Compaq RAID Array 4000 Storage System: Deployment and Configuration

Single Server/Dual Controllers

Figure 3. RA4000 Storage System with Single Server/Dual Controllers
Customers who want a redundant storage system, but do not require a server cluster, can deploy a
system containing a single server/dual controller deployment scenario.
Customers deploying a single server or installing an entirely new storage system with a single
server/dual controllers configuration must:
1. Insert a GBIC into two Fibre Channel Host Adapters.
2. Install the two Fibre Channel Host Adapters into the server.
3. Insert a GBIC into each of two Fibre Channel Storage Hubs. Use a GBIC-SW if the
connection to the server is 500 meters or less, or a GBIC-LW if the connection to the server is
between 500 meters and 10 kilometers.
IMPORTANT: Systems deploying GBIC-SW use 50-micron, multi-mode fiber optic cable.
Systems deploying GBIC-LW use 9-micron, single-mode fiber optic cable.
4. Connect a Fibre Channel Storage Hub to each Fibre Channel Host Adapter.
5. Insert a GBIC into each array controller at the RA4000(s). Use a GBIC-SW if the connection
to the hub is 500 meters or less, or a GBIC-LW if the connection to the hub is between
500 meters and 10 kilometers.
IMPORTANT: One Fibre Channel link per array controller is required.
Note: The necessary GBIC and the appropriate fiber optic cable are determined by individual
customer needs and system design.
