This section shows design examples of the PRIMECLUSTER system. Refer to these examples when designing the PRIMECLUSTER system.
System configuration
Figure A.1 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 (ETERNUS3000 model 300 (FC)) x 1
Operation management personal computer x 1
Used software
Solaris 10
Enhanced Support Facility 2.0
PRIMECLUSTER 4.2A00
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)

System disk settings
Node name | Physical disk name | Slice number | Slice name | Size (MB) |
|---|---|---|---|---|
node:primecl01 | c0t0d0 | 0 | / | 15374 |
1 | swap | 2048 | ||
2 | backup | 17423 | ||
node:primecl02 | c0t0d0 | 0 | / | 15374 |
1 | swap | 2048 | ||
2 | backup | 17423 |
Note
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 | Number of LU | Number of RAID groups | RAID level | Size |
|---|---|---|---|---|
ETERNUS3000 model 300(FC) | 4 | 1 | 5 | 248.2 GB |
Expansion file unit (FC) x 2 | - | - | - | 18.2 GB |
Note
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.
