■
For clusters using Ethernet interconnect:
G One Compaq NC3123 Fast Ethernet NIC (NC3123 NIC) PCI 10/100
Wake on LAN (WOL) installed into slot 1 of each server for public
network access
G One crossover cable for the cluster interconnect (provided in the
cluster kit)
■ For clusters using ServerNet™ I interconnect:
G One ServerNet I PCI adapter installed into slot 1 of each server
G Two ServerNet I cables
Storage Components
The U/300 kit for the ProLiant DL380 server supports the following storage
hardware components:
■ One RA4100 storage subsystem, including one Compaq StorageWorks
RAID Array 4000 primary array controller (RA4000 controller)
■ One RA4000 redundant array controller
■ Two GBIC-SWs, one in each controller
■ Two 9.1-GB or larger disk drives, one in each slot 0
■ Two multimode Fibre Channel cables
Cluster Interconnect
ProLiant Clusters for SCO UnixWare 7 with the ProLiant DL380 server can
use either a high-speed ServerNet I network or a dedicated, private Ethernet
network to connect the cluster nodes. The cluster nodes use the interconnect
data path to support the following cluster features:
■ Cluster-wide file system
■ Cluster-wide process management, migration, and load balancing
■ Cluster-wide networking and Cluster Virtual IP (CVIP)
■ Cluster-wide system administration and management
The ServerNet I cluster interconnect uses two ServerNet I PCI adapters and
two ServerNet I cables to connect the nodes. The Ethernet cluster interconnect
uses the embedded NICs and an Ethernet crossover cable to connect the two
nodes.
