Compaq StorageWorks High
Availability Storage Solution for ProLiant
The High Availability Storage Solution for ProLiant is a pre-tested configuration of hardware, software, installation, and customer training that is targeted at
moving large Microsoft Exchange servers into a SAN-compatible environment.
It provides a first step toward simplifying rapidly growing storage deployment by combining appropriate Compaq products with services and customer
training to meet the requirements of a typical medium-sized storage configuration attached to ProLiant servers. All the components of the High Availability
Storage Solution for ProLiant are “SAN-ready”, and can become part of a future Compaq Storage Area Network installation.
Microsoft Exchange Solution
In today's information age, collaboration via electronic communication is an essential part of every business. Microsoft Exchange Server contains
collaboration tools that help develop a wide range of collaborative solutions.
The High Availability Storage Solution for ProLiant easily satisfies the storage capacity and performance needs of a dual server Microsoft Exchange
configuration. Migration from existing server based Exchange Server configurations to the High Availability Storage Solution for ProLiant is a
straightforward. Compaq provides a fully documented migration process. The High Availability Storage Solution for ProLiant supports smooth future
migration to a full SAN configuration.
Hardware and Softwar e Components
The High Availability Storage Solution for ProLiant consists of the following components:
• Two independent Fibre Channel loops, each capable of transferring data at 100 megabytes per second.
• Four Fibre Channel Host Adapters and two Fibre Channel Storage Hub 7 to link the servers to the Fibre Channel loops. The two loops insure that if
one loop fails, all the data in the storage system is still available.
• Two dual controller RAID Array 4000 systems. Each system holds up to twelve 18.2 gigabyte disks or eight 36.4 gigabyte disks.
• One 22U Rack 9000 with 13U available to mount existing ProLiant Microsoft Exchange servers. (1U is 1.75 inches (4.45 cm) of vertical height in the
rack.)
• Software for configuration and data management in the RAID environment.
• StorageWorks Virtual Replicator software simplifying the overall management of the storage solution. StorageWorks Replicator can also create
snapshots that can be used for backup, restore, and other purposes.
These components are integrated to provide the Compaq StorageWorks High Availability Storage Solution for ProLiant Solution. Compaq decided to
integrate these specific “best-in-class” components because each one offers the very best technology to solve the problems of migrating an existing
Microsoft Exchange Server system to a SAN-ready storage environment.

Installation
The High Availability Storage Solution for ProLiant is a pre-tested configuration of hardware, software, installation, and customer training that is targeted at
moving large Microsoft Exchange servers into a SAN-compatible environment. Installation is available from Compaq Customer Services, and includes:
• Assembly of hardware components.
• Installation of Fibre Channel host adapters into customer's Exchange servers.
• Configuration of RAID Array 4000 and Fibre Channel hubs into a High Availability storage subsystem.
• Installation of management software.
• Migration of customer's Exchange data from existing disks to the RA4000 disks.
• System Verification Test.
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 node-bypass capabilities.
The High Availability Storage Solution for ProLiant configuration uses two independent Fibre Channel Arbitrated Loops to provide full no-single-point-offailure redundancy. Each loop implements an independent Fibre Channel Fabric. Any failure on one Fabric causes the system to use the other Fabric for
communication between the servers and the external storage. For the purposes of this Solution, one loop is called "Fabric A", and the other is called
"Fabric B".

Availability Storage Solution for ProLiant
StorageWorks RAID Array 4000
The Compaq High Availability Storage Solution for ProLiant Solution uses two dual-redundant RA4000 RAID subsystems. These include a total of four
RAID controllers in two separate rack mounted enclosures. Each RA4000 subsystem operates completely independently, and the redundant controller in
each subsystem protects against controller failures.
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
copy--which maximizes READ performance.
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.
