Hi,
I'm looking for some recommendations for a new "scratch" file server for
our cluster. Rough requirements are:
- Around 20TB of storage
- Good performance with multiple nfs writes (it's quite a mixed workload
so hard to characterise further)
- Data security not massively important as it's just for scratch /
temporary data.
It'll just be a single server serving nfs, I'm not looking to go down
the luster / pvfs route.
a) what network fabric (IB, 10GbE, GbE, ...)
b) roughly how many simultaneous writers ... large block streaming, or
small block random? How much sustained IO (MB/s) do you need to support
your worker machines?
c) looking to build it your self or buy units that work?
