PRIMECLUSTER Installation and Administration Guide 4.2 (Linux for Itanium)

A.11 System Design Examples

This section shows design examples of the PRIMECLUSTER system. Refer to these examples when designing the PRIMECLUSTER system.

System configuration

[System configuration example]

Note: The NTP server should be set to one of the following operation mode;

• Maintains time that is reliable for special hardware devices such as time units and GPS units.

• Uses another server that maintains time that is reliable for special hardware devices such as time units and GPS units, and uses NTP for time synchronization.

Used hardware

• PRIMEQUEST x 2

• FC-Switch x 1 unit

• LAN card x 6

• Fibre channel card x 4

• Disk array unit x 2

Used software

• Red Hat Enterprise Linux AS

• PRIMECLUSTER 4.2A00

• Multipath driver

• Netscape Communicator 4.7x (installed in the operation management personal computer)

• Java(TM) 2 Runtime Environment Standard Edition v1.4.2(installed in the operation management personal computer)

• IBM(R) Runtime Environment for Linux(R), Java(TM)2 Technology Edition, Version 1.3.1, 32-bit version (Installed when Linux(R) is used as the operation management client.)

System disk settings

Node name	Physical disk name	Slice number	Slice name	Size (MB)
primecl01	sda	1	/	15374
		2	/boot/efi	256
		3	swap	2048
primecl02	sda	1	/	15374
		2	/boot/efi	256
		3	swap	2048

When GDS is used to mirror the system disk, it uses one slice number and at least 32 MB of unused area (or swap area) on the system disk. If system disk mirroring is to be executed, consider the resources used by GDS when designing the system.

Shared disk array settings

Device name: ETERNUS3000	Number of LU	Number of RAID groups	RAID level	Size
	4	1	5	248.2GB
