Note: In single server environments, the server can be connected directly to the RA4000. 7. Run the Compaq Options ROMPaq. It is provided on the Compaq SmartStart and Support Software CD 4.30 or later that is shipped with the Compaq StorageWorks RA4000 and RA4000 Redundant Controller. Dual Servers/Dual Controllers Figure 4. RA4000 Storage System with Dual Servers/Dual Controllers The most common configuration uses a system containing two servers and two array controllers. The dual servers/dual controllers configuration ensures hardware redundancy. Customers migrating from a single server to a server cluster or installing an entirely new storage system with a dual servers/dual controllers configuration must: 1. Insert a GBIC into two Fibre Channel Host Adapters. 2. Install the two Fibre Channel Host Adapters into the added server or to both servers if the storage system is entirely new. 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 in each server. 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. 0206-0699

RA4000 Storage System with Dual Servers/Dual Controllers
The most common configuration uses a system containing two servers and two array controllers.
The dual servers/dual controllers configuration ensures hardware redundancy.
Customers migrating from a single server to a server cluster or installing an entirely new storage
system with a dual servers/dual controllers configuration must:
1.
Insert a GBIC into two Fibre Channel Host Adapters.
2.
Install the two Fibre Channel Host Adapters into the added server or to both servers if the
storage system is entirely new.
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 in each server.
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.
