Fibre Channel Arbitrated Loop
The Compaq High Availability Storage Solution for ProLiant Solution uses Fibre Channel Arbitrated Loop technology to transfer data between the servers and the external storage subsystems. Fibre Channel Arbitrated Loop delivers the advantages of 100 MB/s bandwidth, up to 126 addressable connections, easy cabling, 500 meters (546.8 yards) to 10 kilometer (6.21 miles) distances between nodes, hot pluggable and
The High Availability Storage Solution for ProLiant configuration uses two independent Fibre Channel Arbitrated Loops to provide full
StorageWorks RAID Array 4000
The Compaq High Availability Storage Solution for ProLiant Solution uses two
RAID levels 0 (striping), 1 (mirroring), 4 (block parity) and 5 (distributed block parity) are supported by the RA4000. For maximum data availability in case of disk failure, and to maximize I/O request performance, RAID 1 (mirroring) is the preferred option for the High Availability Storage Solution for ProLiant. In mirrored data subsystems, two complete copies of all of the user's data are maintained, and READ requests from the server can be handled from either
Each RA4000 supports up to 64 megabytes of cache memory. This is used to optimize the performance of Microsoft Exchange Server application.
Fibre Channel Storage Hub 7
The Fibre Channel Storage Hub 7 is a 7 port Fibre Channel Hub. The two Hub 7s in this solution provide the Fibre Channel interconnection fabric for the High Availability Storage Solution for ProLiant Solution. Each hub provides two ports for host connections and two ports for storage connections, with additional ports for later expansion. The Hub 7s are mounted in the Rack 9000 in a 1U form factor.
Fibre Channel Host Adapter Kit / PCI
The Fibre Channel Host Adapter Kit / PCI provides the capability to attach Compaq ProLiant servers to the Fibre Channel interconnection fabric. Each Fibre Channel Tape Host Adapter has a single Fibre Channel port that provides a fiber optic connection to the Storage Hub 7. Each Host Adapter Kit uses one PCI slot in a ProLiant server. To achieve data path redundancy, each server has two Host Adapter Kits. Each server has one connection to Fabric A and a separate connection to Fabric B.
