I've been asked to setup a 3d renderfarm at our office , at the start it
will contain about 8 nodes but it should be build at growth. now the
setup i had in mind is as following:
All the data is already stored on a StorNext SAN filesystem (quantum )
this should be mounted on a centos server trough fiber optics , which
in its turn shares the FS over NFS to all the rendernodes (also centos).
Now we've estimated that the average file send to each node will be
about 90MB , so that's what i like the average connection to be, i know
that gigabit ethernet should be able to that (testing with iperf
confirms that) but testing the speed to already existing nfs shares
gives me a 55MB max. as i'm not familiar with network shares performance
tweaking is was wondering if anybody here did and could give me some
info on this?
Also i thought on giving all the nodes 2x1Gb-eth ports and putting those
in a BOND, will do this any good or do i have to take a look a the nfs
server side first?
