Architecture of the Compaq ProLiant

Clusters HA/F100 and HA/F200

Overview of Compaq ProLiant Clusters

HA/F100 and HA/F200 Components

A cluster is a loosely coupled collection of servers and storage that acts as a

single system, presents a single-system image to clients, provides protection

against system failures, and provides configuration options for static load

balancing.

Clustering is an established technology that may provide one or more of the

following benefits:

■ Availability

■ Scalability

■ Manageability

■ Investment protection

■ Operational efficiency

Compaq ProLiant Servers

Compaq industry standard servers are a primary component of all models of

Compaq ProLiant Clusters. At the high end of the ProLiant server line, several

high availability and manageability features are incorporated as a standard part

of the server feature set. These include online backup processors, a PCI bus

with hot-plug capabilities, redundant hot-pluggable fans, redundant processor

power modules, redundant Network Interface Controller (NIC) support,

dual-ported hot-pluggable 10/100 NICs and redundant hot-pluggable power

supplies (on most high-end models). Many of these features are available at

the low end and mid range of the Compaq ProLiant server line, as well.

Compaq has logged thousands of hours testing multiple models of Compaq

servers in clustered configurations and has successfully passed the Microsoft

Hardware Cluster Certification Test Suite on numerous occasions. In fact,

Compaq was the first vendor to be certified using a shared storage subsystem

connected to ProLiant servers through Fibre Channel Arbitrated Loop

technology.

NOTE: Visit the Compaq High Availability website

(http://www.compaq.com/highavailability) to obtain a comprehensive list of

cluster-certified servers.

The Microsoft Cluster Software (MSCS) is based on a cluster architecture

known as shared storage clustering, in which clustered servers share access to

a common set of hard drives. MSCS requires all clustered (shared) data to be

stored in an external storage system.

The Compaq StorageWorks RA4000/4100 storage system is the shared storage

system for the Compaq ProLiant Clusters HA/F100 and HA/F200.

Compaq StorageWorks RAID Array 4000 or Compaq

StorageWorks RAID Array 4100

The Compaq StorageWorks RAID Array 4000 Compaq StorageWorks RAID

Array 4100 (RA4000/4100) is the storage cabinet that contains the disk drives,

power supplies, and array controllers. The RA4000/4100 supports the same

hot-pluggable drives as Compaq Servers and Compaq ProLiant Storage

Systems, online capacity expansion, online spares, and RAID fault tolerance

of SMART-2 Array Controller technology. The RA4000/4100 also supports

hot-pluggable, redundant power supplies and fans, and hot-pluggable hard

drives.

The HA/F100 and HA/F200 ProLiant Clusters must have at least one

RA4000/4100 set up as an external shared storage. Consult the Order and

Configuration Guide for Compaq ProLiant Cluster HA/F100 and HA/F200 at

the Compaq ProLiant Clusters High Availability website

(http://www.compaq.com/highavailability) to determine the maximum supported

cluster configuration.

Compaq StorageWorks RAID Array 4000 Controller

The Compaq StorageWorks RAID Array 4000 Controller (RA4000

Controller) is fully RAID capable and manages all of the drives in the

RA4000/4100 storage array. Each RA4000/4100 is shipped with one controller

installed. In a HA/F100 cluster, each array controller is connected to both

servers through a single Fibre Channel storage hub or FC-AL switch. In a

HA/F200 cluster, the addition of a second Compaq StorageWorks RA4000

Redundant Controller is required to provide redundancy.

These redundant controllers are connected to each server through two separate,

and redundant, Fibre Channel storage hubs or FC-AL switches. This

dual-connection configuration implements a vital aspect of the enhanced high

availability features of the HA/F200 cluster. Each of these components is

discussed in the following sections. For more information, refer to the Compaq

StorageWorks RAID Array 4000 Redundant Array Controller Configuration

Poster.

For more information about shared storage clustering, refer to the Microsoft

clustering documentation.
