[Bioclusters] Need NFS with local disk based caching, CODA?

Our bioinformatic database files are outgrowing
 the nodes capacity to store them,  (~24Gig).

Plenty of space on the fileserver but we find
 that cluster throughput levels off at about 10 nodes
 when the databases are provided through NFS.

We need something that provides a network file system
 but with local caching.   24 Gig will be heaps of space
 to keep a good selection of the popular databases locally.

When someone asks for something esoteric or after an update
 we have a short pause while the information is re-distributed
 and we are humming again.

I thought to use CODA
 but find a whierd mix of doco dating from 1900s
 and somone contributing modules for current kernels.

Anyone got any experience with Coda?

And if it's no good, what are the alternatives?

What are other clusters using?
