OVERVIEW
The 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 Software 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.

OVERVIEW (continued)
Hardware Support, Configuration, and Diagnostic Software
The High Availability Storage Solution for ProLiant uses standard, fully supported Compaq hardware and software products. All supporting material,
including support, configuration, and diagnostic functions are exactly the same as those used in the individual products. All support, configuration, and
diagnostic software is included in the solution.
Integrated Software Solutions
A key component of the Compaq StorageWorks High Availability Storage Solution for ProLiant is storage management application software.
StorageWorks Virtual Replicator is a Windows NT driver-level application that supports two important management features. StorageWorks Virtual
Replicator can be used to simplify overall storage management by creating “pools” of storage capacity from disks in the RA4000 systems, and from other
disks connected to the host servers. Virtual disks may be created from the storage capacity in a pool, and these virtual disks may be used like any other
disk available to Windows NT. StorageWorks Virtual Replicator can also be used to create snapshots of any disk. A snapshot is a copy of a disk that is
created almost instantaneously and can be used as a quick source for data recovery, and other purposes.
In the Compaq StorageWorks High Availability Storage Solution for ProLiant the StorageWorks Virtual Replicator application is used in several ways. For
the Microsoft Exchange Server data stored in the High Availability Storage Solution for ProLiant subsystem, the snapshot allows fast data restore
operations. For other data stored in the High Availability Storage Solution for ProLiant, the snapshot can also be used for data backup, restore, and
management activity needed in routine operations. In addition, the virtual pool capability of Virtual Replicator can be used to provide virtual disks that meet
the particular requirements of a specific user application.
Scalability
The solution capacity can be increased to as much as 436 GB using 18 GB disk drives (total capacity is 24 disks). In addition, both performance and
capacity can be scaled with the addition of RA4000 units, and each RA4000 holds 12 disks of up to 36 GB each.
The High Availability Storage Solution for ProLiant is compatible with Compaq StorageWorks Storage Area Network products. As your installation evolves
toward larger SAN deployment, all the hardware and software in the High Availability Storage Solution for ProLiant can remain part of the installation. This
means that the solution can be scaled in the context of a larger Storage Area Network.
Smooth Integration/Installation
The Compaq High Availability Storage Solution for ProLiant integrates smoothly into an existing Microsoft Exchange environment. All the components are
customer installable. Installation is also available from Compaq.
Prerequisites
The Compaq High Availability Storage Solution for ProLiant is designed to work with an existing customer environment that includes the following
components.
•
Two ProLiant servers (See the Compatibility Matrix for supported servers located in the Sizing and Configuration Guide) Configured in a MSCS
cluster
•
•
One ProLiant server running Exchange Server with failover selected for second ProLiant server
The second (failover) server can be used for other applications.
Warranty
The Compaq High Availability Storage Solution for ProLiant is covered by a three-year parts warranty, one-year on-site warranty and a one-year labor
warranty.
Note: Certain restrictions and exclusions apply. Consult the Compaq Customer Support Center for details. In Canada, consult the Product Information
Centre at 1-888-88-COMPAQ.
