RE: [Xen-users] disk backend performance

["Venefax" <venefax@xxxxxxxxx>]

My system disk is a raid 5 array, 800 GB, so it has plenty of throughput.
But you say that any technique even NFS or even SAMBA, versos creating a
file and sharing it via AOE will be comparable?
Which technique would you pick? I have a back-to-back 1 GB Ethernet cable
between the two servers.

Federico,
If your interests performance, you're wasting your time nit picking the
difference's
in how you export storage if you're doing it all off the system disc whether
it's a raw
partition exported or a directory or a file on your filesystem exported as a
raw device...

If you have only one disc at your disposal, you're not going to squeeze that
last little bit
out
