Manny,

Very good points. And that is our design. However, lack of strict
adherence to our standard has led to two problems. First, several servers
didn't get cabled with two connections. Second, the folks who manage the
servers have challenges with the NIC configurations. So while we expect
many of the servers can sustain the loss of one NIC, we have several that
we know and many that we may not know, will lose network connectivity as
we flip the connection to the new switch.

VM can't get rolled out fast enough. sigh
