Installation and Service
Each model also provides two 1-GB Ethernet ports for communication with
the Management Node or connection to the backbone of the network.
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 Models 3508G (8-port). The 1-GB Ethernet
switch uses either optical or copper cable with one of two optional GBICs.
The port server provides serial connections for cluster modules. The
Cluster 1350 uses the MRV
In-Reach IR-8040–101 (40–port).
The main purpose of the port server is to assign Ethernet addresses to
cluster components. The port server can also act as a backup for Ethernet
connections to download firmware and to check information stored in logs
in cluster components.
This is an optional 2-GB switch for interconnecting Cluster Nodes and
Storage Nodes. The Cluster 1350 uses the Myrinet
M3-E64 (9-slot), and M3-E128 (17). The high-speed switch can replace the
optional secondary Ethernet. It requires a Myrinet PCI adapter in each
Cluster Node and Storage Node. The Myrinet Switch uses an optical cable.
The Cluster 1350 can also use the Cisco
Catalyst 4006 (6–slot) switches with optional 10/100/1000 line cards to
provide a high-speed Cluster VLAN or to provide a second high-speed
Ethernet network at a lower cost than the high-performance Myrinet
network.
The Power Management Module provides power to the service processors
(RSA boards) and to the port servers. The Cluster 1350 uses the APC
™
MasterSwitch Model AP9212. The Power Management Module can
supply up to eight connections. It provides the ability to power-cycle a
component remotely.
The PDU provides AC power within the cabinet. The PDUs are mounted
sideways beside the regular rack space. Two types of PDUs are used:
v Rack PDU
v Front end PDU
Rack PDUs provide power to components within a cabinet, while front end
PDUs provide the connection to the external power source and distribute
the power among the rack PDUs. A rack PDU can also be directly
connected to the external power source to eliminate the need for the front
end PDU. Up to four front end PDUs can be placed in each cabinet and up
to twelve rack PDUs.
