Scratch that. Don't get Linksys SD2005.

Question:

Can we use an 100 Mbit switch for interconnect?


We have a pair of computers. One of them is exporting a directory through
NFS, the other is making a backup of it. This backup kept getting stuck in
the middle. Nothing helped except changing the switch, just now. With a
differrent, 100 Mbit switch, backup worked ten times without error.

We have the same type of switch on the interconnect of a cluster that has been
crashing.

It's probably a freak incompatibility between the switch Linksys SD2005 and
the network cards Broadcom NetXtreme BCM5700.

I'll make another test: putting the Linsys back and setting the network cards
to 100 Mbit. Then I'll try the same backup, 10 times.

But: can we use 100 Mbit switch for Oracle RAC interconnect? 10gR2 DB RAC,
10gR2 Clusterware.

Thank you.
