Chapter 1. System overview
This chapter provides an overview of the IBM
®
System Cluster 1350 software
components, hardware components, and related documentation.
The Cluster 1350 uses two types of cabinets: primary and expansion. A cabinet is
called primary if it contains the management node and console monitor. An
expansion cabinet can contain storage nodes or mass-storage devices as well as
computing nodes, called cluster nodes; it does not contain a management node or
a console.
The cluster may consists of:
v
One or more racks.
v
From four to 1024 cluster nodes. The nodes are configured to run customer
applications or provide other services required by the customer, such as file
server, network gateway, or storage server.
v
One management node (System x3650 or System x3655) for cluster systems
management (CSM) and administration.
v
A management Ethernet VLAN that is used for secure traffic for hardware
control.
The management Ethernet VLAN is used for management traffic only. It is
logically isolated for security using the VLAN capability of the Cisco Ethernet
switches, and it is only accessible from the management node. The cluster VLAN
and management VLANs share the same physical switches.
v
A cluster VLAN used for other management traffic and user traffic. Switches
integrated with the cluster are used for the management Ethernet VLAN and the
cluster Ethernet VLAN.
v
Service processor networks. All nodes in the cluster are connected through serial
service processors (such as the System x3650). The first node in a serial
connection must have a management node, which is connected through the
Ethernet to the management-Ethernet VLAN.
v
A terminal server network for remote or local console. Optionally, the customer
might elect to include an additional network.
v
A high-performance Myrinet 2000 cluster interconnect, an additional Gigabit
Ethernet, or an InfiniBand switch.
v
The customer can elect to configure a subset of cluster nodes with additional
external storage. This can be a Fibre Channel solution.
v
A supported distribution of the Linux operating system.
v
Cluster systems-management software, such as CSM.
The Cluster 1350 supports a maximum of 1024 nodes in addition to the one
required System x3650 (or the System x3655 management node for 64-bit
processing environments) management node. All nodes must run one of the
following Linux versions:
v
Red Hat Enterprise Linux (RHEL), version 4 for AMD or EMT (32-bit or 64-bit)
v
RHEL, version 4 for AMD or EMT (64-bit)
v
SUSE LINUX Enterprise Server (SLES), version 9 for AMD or EMT (64-bit)
v
SLES, version 10
v
Linux Cluster Installation Tool (LCIT), version 5.0
