I will be upgrading the existing 100-base-T switch to a Gigabit switch to accommodate increased traffic between the file servers and other machines.

This increase traffic is largely the result of a move from NFSv3 to NFSv4.  NFSv3 wasn’t able to use the full bandwidth of a 100-base-T connection but NFSv4 will totally saturate the link during a large file move.  This is resulting in occasional latency spikes.

The change-out will create only brief interruptions of several seconds as machines are moved from one switch to the other (a physical movement of connectors over a distance of several inches).
