Keeping systems alive - even during disasters (page 4 of 4)

Sites are usually less than 100KM apart. If one server fails it can failover locally or remotely to the second site.

• Using Replication: A single cluster stretched out between two sites connected over an IP network. Distances can be further apart than with mirroring, but not usually more than a couple of hundred kilometres. If one server fails it can failover locally or remotely to the second site.

• Wide Area Disaster Recovery: Two separate networks control each site. If one site fails, all traffic gets redirected to the second site. This architecture supports unlimited distances.

Summary
In today's networked economy having systems available 24 hours a day is critical in ensuring success for any organisation, which is why availability should not just be focused on data, but also on servers and applications.

With only 5% of all organisations using availability solutions for mission-critical systems, many are at risk of losing transactions, revenue, brand image, or even worse (source: VERITAS Disaster Recovery Survey, September 2004).

A good question to ask yourself is how much would 1 hour of downtime cost your business in both external and internal costs? The answer alone should provide justification for implementing an application availability solution.

"One time we came in Monday morning and everything was running as usual. We didn't even realize till later that the server was down and VERITAS Cluster Server had done a fail-over. It was seamless."
