coincide with support contracts on hardware if desired. This solution also includes support for Red
Hat, 3-year Red Hat Enterprise Linux Advanced Platform 24x7 either 1 to 2 sockets or unlimited
sockets depending upon the server chosen (visit http://www.hp.com/go/proliantrhel for more
information). Please note that support is highly recommended for all high availability solutions.
For Linux management to complement the SGLX capabilities in multi-system environments, HP's ICE-
Linux solution provides an integrated solution for system discovery, deployment & imaging,
monitoring, and management. HP ICE-Linux auto-configures Nagios and other open source software
to allow you to be quickly productive with Linux management, while still preserving flexibility and
extensibility.
For more details on the various support options available from HP and ICE-Linux, please consult with
your HP Sales Representative or Partner.
Getting Started
Hardware setup and networking planning must be completed before you start the installation.
Hardware Setup
The 2 servers and external storage device must be cabled for power, network, and storage
connectivity. For initial set-up of the MSA2000 storage device, a serial console device will be
needed. This can be done on a Windows laptop using the HyperTerminal software or with another
system running similar terminal software along with the Mini DB9 RS232 Serial cable supplied with
the MSA2000. A keyboard, mouse, and monitor will be required for use as a console to install the
operating system on each of the servers. 5 Ethernet cables are required (two for each server and one
for the storage device) along with access to 2 network switches (see Figure 1). Storage cabling is
described in “Connecting the MSA2000 to the servers” and illustrated in Figure 2. Four Fibre
Channel cables are required to connect the storage device to the servers.
Tip:
Do not connect the Fibre Channel cables to each server until after the OS
has been installed on each server, otherwise the OS installation process
may attempt to place the boot image on the external storage device.
Network Planning
The minimum network configuration requires 2 network connections configured as a bonded pair
running a heartbeat and the public network connections from each server. Each network connection
should be plugged into separate switches (see Figure 1). If three network connections are used, one
should be configured in a private heartbeat network (shown in grey in Figure 1) and the other should
be a bonded pair for the public and heartbeat networks. The manual “Managing HP Serviceguard
for Linux” goes into more detail.
