Abstract:
Compaq is renowned in the Enterprise market with its industry-
leading, highly available, fault-tolerant servers. Compaq servers and storage
deliver on this reputation by offering the highest level of reliability and
uptime with features such as:
•
Industry standard PCI Hot Plug and internal hot-plug storage
•
Redundant hot-plug fans, power supplies, and NICs
•
Automatic Server Recovery-2 (ASR-2)
•
ECC protected memory
•
Integrated Management Display (IMD)
•
Integrated Remote Console (IRC)
•
Compaq SmartStart and Compaq Insight Manager
The Compaq ProLiant Cluster for NetWare 4.2 is designed to help
customers reduce the risk and costs of downtime due to hardware or
software failures. Benefits include:
•
Automatic failover protection - In the event of a failure on one server,
the remaining server maintains availability of network data and
resources.
•
Active servers - Users can now cluster two active NetWare 4.11 or
NetWare 4.2 servers on the network, providing failover support and
significant cost savings, since purchasing a dedicated server for failover
is no longer necessary.
•
Shared storage - Support for shared storage devices allows customers to
reduce overall management costs by centralizing administration and
back-up. Shared storage also allows more efficient use of storage space
by eliminating the need to maintain duplicate files on different servers.
•
No single point of failure – The new Compaq StorageWorks RAID
Array 4000 storage system provides redundant fibre channel loops for
No Single Point of Failure configurations.
The ProLiant Cluster for NetWare 4.2 provides the highest levels of system
and application availability for customers with high system uptime
requirements for NetWare 4.x environments. These levels are necessary to
meet the requirements of demanding business-critical environments. This
Integration Note details the configuration options and server requirements,
provides insight into the administration, and describes some of the features
available with the ProLiant Cluster for NetWare 4.2.
