2 Planning SGeRAC Installation and Configuration
This chapter contains the following topics:
• “Installation Requirements” (page 21)
• “About CVM and CFS in an SGeRAC Environment” (page 23)
• “Overview of SGeRAC Installation and Configuration Tasks” (page 27)
Installation Requirements
Make sure each node on which you want to install or upgrade SGeRAC meets the installation
requirements.
• “Hardware Requirements” (page 21)
• “Supported Software” (page 22)
• “Supported Operating Systems” (page 22)
• “Supported HP-UX Operating Environments” (page 22)
• “Required HP Patches” (page 23)
Hardware Requirements
Make sure that you have the correct equipment to install SGeRAC
Table 2-1 Hardware Requirements
DescriptionItem
From two to sixteen HP-UX systems connected to the public network running HP-UX 11i v3.
HP recommends that each system have two or more CPUs at 2GHz or higher.
SGeRAC Systems
One drive that is accessible to all nodes in the cluster.DVD Drive
Typical SGeRAC configurations require that shared disks support applications that migrate
between systems in the cluster.
The coordinator disk does not store data, so configure the disk as the smallest possible LUN
on a disk array to avoid wasting space.
NOTE: With HP-UX 11i v3 you must use Dynamic Multipathing (DMP) devices for path
failover and I/O load balancing.
Disks
See “Disk Space (local)” (page 21)Disk Space
Each SGeRAC system requires at least 256 megabytes.
HP recommends 2 GB or more of physical memory.
RAM
HP recommends at least double of main memory.Swap Space
Two or more 100BaseT or Gigabit Ethernet links directly linking each node to the other node
to form a private network that handles direct inter-system communication.
HP recommends switches for the private network links. These links must be of the same type;
you cannot mix 100BaseT and Gigabit.
Network Links
SGeRAC requires at least one built-in SCSI adapter per system to access the operating system
disks, and at least one additional SCSI or Fibre Channel Host Bus Adapter per system for
shared data disks.
Fibre Channel or
SCSI Host Bus
Adapters
Disk Space (local)
Confirm that your system has enough free disk space to install SGeRAC. Each node in the cluster
requires at least the following local disk space for the SGeRAC depots:
