PRIMECLUSTER Installation and Administration Guide 4.1 (for Solaris(TM) Operating System)

A.10 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

• PRIMEPOWER 200 x 2
• Expansion file unit x 2
• Remote console unit (RCCU) x 2
• Fibre channel switch (SN200) x 2
• Fast Ethernet card x 6
• Fibre channel card x 6
• Disk array unit (GR720) x 1
• Operation management personal computer x 1

Used software

• Solaris 8
• Solaris 8 PTF (R02021)
• Solaris Unbundled PTF (R02021) (for PRIMEPOWER)
• Enhanced Support Facility 2.0
• PRIMECLUSTER 4.1A10 Enterprise Edition
• Multipath Disk Control 2.0
• Multipath Control Load Balance Option 2.1
• Fujitsu PCI Fibre Channel 2.2
• Netscape Communicator 4.7x (installed in the operation management personal computer)
• Java(TM) 2 Runtime Environment Standard Edition v1.3.1 (installed in the operation management personal computer)

System disk settings

node:primecl01	Physical disk name	Slice number	Slice name	Size (MB)
	c0t0d0	0	/	15374
		1	swap	2048
		2	backup	17423
node:primecl02	Physical disk name	Slice number	Slice name	Size (MB)
	c0t0d0	0	/	15374
		1	swap	2048
		2	backup	17423

If GDS is used for system disk mirroring, one slice number in the system disk and at least 32 megabytes of free area (or swap area) are used.
You need to consider the resources used by GDS when designing the system.

Shared disk array settings

Device name: GR720 (FC)	Number of LU	Number of RAID groups	RAID level	Size
	4	1	5	248.2 GB
Device name: Expansion file unit (FC) x 2	-	-	-	18.2 GB

To use the disk array units on UNIX, you need to format them by executing the "format (1M)" command.
When formatting the disk array units as part of the cluster system configuration work, you need to estimate the formatting time.
