IBM eserver Cluster 1350, Installation And Service Manual

1 Gb Ethernet switch
The 1 Gb Ethernet switch provides a 1 Gb Ethernet trunk line between the
management node and the cluster and storage nodes. The Cluster 1350 uses the
Cisco Ethernet switch model 3508G-XL (8-port) and the SMC Ethernet switch model
8624T(24-port) as Gigabit Ethernet switch options. The 1 Gb Ethernet switch uses
an optical cable.
SMC mini-GBIC expansion module
The SMC mini-GBIC expansion module (SMCBGLSCX1) provides a network line
that allows you to plug into any small form-factor (SPF) slot for Gigabit Ethernet
network expansion.
Terminal server
The terminal server provides serial connections for cluster modules. The Cluster
1350 uses the In-Reach LX-4000 (32–port) switch or the In-Reach LX-4000
(48-port) switch as a terminal server.
The main purpose of the terminal server is to assign Ethernet addresses to cluster
components. The terminal server can also act as a backup for Ethernet connections
to download firmware and to check information stored in logs of cluster
components.
High-speed Myrinet switch
This is an optional 2 Gb switch for interconnecting cluster nodes and storage
nodes. The Cluster 1350 uses the Myrinet models M3-E32 (5-slot), M3-E64 (9-slot),
M3-E128 (17-slot), M3F-PC164C-2 (PCI adapter), and M3F-PCIXD-2 (PCI card).
The high-speed switch can replace the optional secondary Ethernet switch. It
requires a Myrinet PCI adapter in each cluster node and storage node. The Myrinet
switch uses an optical cable.
Myrinet cluster expansion card
The I/O expansion card provides a high-speed interconnect for blade servers. The
expansion card provides the distribution of computing over several blade servers.
High-speed Cisco switch
The Cluster 1350 can also use the Cisco Catalyst 4003 (3-slot) and Cisco Catalyst
4006 (6-slot) switches for a lower-cost high-speed solution.
Power management module
The power management module provides power to the service processors (in
xSeries 335 servers) and to the terminal servers. The Cluster 1350 uses the APC
MasterSwitch Model AP9212. The power management module can supply up to
eight connections. The power management module lets you shut down and restart
a component from a remote site.
Power distribution unit (PDU)
Each rack contains one or more of the following power distribution units:
v IBM NetBAY rack power distribution unit (PDU)
v
IBM NetBAY front-end power distribution units
v IBM Distributed Power Interconnect (DPI
®
) rack power distribution units
v
IBM Distributed Power Interconnect (DPI) front-end power distribution units
