We have recently been having problems with bandwidth on a 1GB lan extension link between our office and data centre.
The bandwidth used to average at about 2% - 10% but now averages at 35%+ with periodic bursts of over 100%.
This is due to a new SAN that has been installed by an external company. They say that the SAN is permanently replicating and it is normal to use that amount of bandwidth.
It is set to use up to 75% of available bandwidth and that 35% is quite low.
Can someone confirm this is correct or even suggest a solution other than get another link?
The links at the sites are 1gb into MDS switches.
