HP NetServer LPr
with
XP256 (Fibre Channel or SCSI)
Cluster Configuration Guide
08 February, 2000
Introduction
This document defines the supported HP NetServer LPr configurations with the XP256 and Microsoft
Cluster Server. These configurations minimize single points of failure (SPOF), provide maximum
availability, and have been certified by Hewlett-Packard or Microsoft. This guide is prescriptive; it
describes the configurations supported by HP. Any deviance to these configurations can result in an
inoperative cluster or an operating cluster with degraded performance, hidden SPOFs, etc., and therefore
will not be supported by HP.
What’s Defined in a Cluster
Cluster
SPUs
Local and Shared Storage
Intra-cluster and Client LANs
Shared Storage Cabling
Cluster
Type of SPUs
HP NetServer LPr.
Each node must be the same model SPU, but may have different clocks
speeds, main memory sizes, cache sizes, and number of CPUs (2, 3, or 4).
Number of nodes
Shared Storage
LANs:
2
XP256 with FC or SCSI connections. See Shared Storage below.
Client LAN
Any NIC that is HP and Microsoft approved. See Client LAN below.
HP D5013A with crossover cable. See Intra-cluster LAN below.
Intra-cluster
(Heartbeat) LAN
Power source
Direct from power mains, power conditioner or uninterruptible power
supply (UPS) using any power conditioner or UPS.
System software:
Navigator version
Operating System
Service pack
L.16.05 or later
Microsoft Windows NT Server 4.0, Enterprise Edition or later
SP5 or later

Shared Storage Configurations
Point to Point
Direct Fibre Channel or SCSI connections. Each SCSI Port on XP256 has
two available connection points (internal logical Y connection); one is
cabled to Server #1 of the cluster, the other to Server #2 (see diag 1, page
5).

A5624A/AZ Brocade 2800 FC Switch
Fabric Support
No. of switches
FL Port (Turn EPL to OFF for desired ports)
1 per SPOF cluster, 2 per SPOFless cluster
No. of clusters/switch SPOF: 1, SPOFless: 4 cluster nodes (See pg.5)

LANs
Intra-cluster (Heartbeat) LAN
Client LAN
LAN connection
HP D5954A crossover cable or
equivalent
Any LAN
The intra-cluster LAN may only be
used for cluster node communication
via a crossover cable. It may not be
used for client communication.
NIC:
Model
HP D5013A (10/100TX PCI)
3.27.00.0001 or later
Any that is on both the HP Tested
Products List and the Microsoft
Hardware Compatibility List.
Driver
Any driver
NOTE If the NIC used is the
same as the Intra-cluster LAN,
then the Client LAN must use the
same driver as the Intra-cluster
LAN.
