There may be some points where things are a bit sluggish today as I migrate some virtual machines from one box to another. This involves copying images around 100GB. With the old 100mb/s switch this would pretty much stop things. I’m hoping not with the 1GB switch, still it’s going to task disk I/O and other resources on the machines pretty heavily.
The purpose for migrating these is for load balancing and to provide better redundancy when physical hosts are down by spreading functionality across multiple physical boxes.
