Hi
Busy setting up our new cell.
I have a some storage coming from a netapp device,(50TB) and some
hopefully coming from a ceph cluster ( hardware on order).
I have read through various mails in this list re performance
of afs on nfs and vm's, and am still no closer to a clear understanding
of the specs I require of my server, I am not in a position to test
10GE vs fibre channel before I pay.
We are trying to get rid of our windows file server and move all to afs,
together with our current hodge podge of nfs servers.
Memory wise I figured the more the merrier so 2 servers, dual socket 6
core with 64GB of ram(ram is cheap), but the stumbling block is fibre
channel or 10GE. I could get more lower spec machines, but then the cost
per bandwidth/proc speed goes up, although I could be wrong.
I have limited experience with recent high end san's is there any real
advantage to fibre channel over 10GE with respect to afs performance
(iscsi or fcoe, *not* nfs) ?
Is fibre channel always suggested for historical reasons ?
I cant see any performance hit from 10GE ? and I get fail over to a dr
site, with 10GE.
Your suggestions would be most appreciated.
Might I suggest list of example configurations and their performances,
this has not been an easy exercise. I am trying to play around with my
current config, but its hard to judge performance on scrap hardware
with only 1GE.
Thanks
Sean
