Avoiding the huge, fast-changing software for configuration management doesn't mean you can't have CM or high availability on cheap boxes. The OpenVMS approach

Avoiding the huge, fast-changing software for configuration management doesn't mean you can't have CM or high availability on cheap boxes. The OpenVMS approach (see Section VI) combined good filesystem, clustering, optional OS-level virtualization, and distributed lock manager to have clustered systems that ran for years without downtime. Record was 17. http://h41379.www4.hpe.com/openvms/whitepapers/high_avail.html http://h41379.www4.hpe.com/openvms/whitepapers/high_avail.ht... Those few building blocks done in a highly-robust way on one of the stable, Linux platforms could probably achieve the same thing. Just RAID 0, a good filesystem, clustering itself, and backups would get far. I know there's Linux-oriented products out there but I don't know if their availability or failover time have caught up yet.
