WAN throughput is limiting factor in many business continuity and disaster recovery plans

A recent survey of 170 IT managers in enterprise environments has found that business continuity and disaster recovery initiatives are being hindered by WAN throughput, and that throwing more bandwidth at the problem does not fix the issues.

The survey, conducted over a 45-day period and sponsored by NetEx, asked IT managers about problems with WAN-based business continuity and disaster recovery solutions. Soliciting the opinions of end users with a cross-section of NAS, array, server, appliance and intelligent switch-based approaches, the survey focused on topics relating to throughput, transport mechanisms and implementation payback periods.

Findings include:
* 65 percent said business continuity and disaster recovery WAN throughput requirements are not always being met.

* 62 percent said that throwing more bandwidth at the problem does not fix throughput issues.

* 63 percent said that business continuity and disaster recovery requirements are increasing faster than the bandwidth can keep up.

* 78 percent said that business continuity and disaster recovery WANs should be able to piggyback on the primary TCP/IP backbone.

* 71 percent agreed that the preferred transport for all business continuity and disaster recovery is with Ethernet/TCP versus Fibre Channel/IP.

* 61 percent agreed that the problems associated with business continuity and disaster recovery throughput increase the risk of non-compliance.

* Half required payback for mixed vendor business continuity and disaster recovery implementation to be within one year; an additional 37 percent require payback within two years.
