Veritas Product Overview
There are several VERITAS products that all work together when running a VERITAS cluster. These are:
- Veritas File System
This is filesystem software. One could use the standard filesystem with ufs logging enabled, however, VERITAS journal filesystem will make your filesystem checks MUCH faster upon reboot/crash.
- Veritas Volume Manager (for partitioning disks)
This software is like a raid manager with more bells and whistles. You stripe, raid, combine, and partition disk groups. One could use Disksuite (free) instead. However, using multiple vendors can be problematic when debugging emergency issues. Additionally, Sun keeps saying that they will discontinue DiskSuite.
- Veritas Cluster Server (High Availability Cluster)
This software enables one system to failover to the other system. All related software processes are simply moved from one system to the other system with minimal downtime. One could use Sun's Cluster product. Veritas is less platform dependant and does not require a terminal concentrator.
You can find out what products you are running with:
