We've had good results with the Coraid EtherDrive 
products.  Fast, inexpensive and extremely simple to 
use.

  Storage questions

  What 
  about iscsi-target?

  You 
  could transform a server in something like an ISCSI 
  storage.

  I 
  use this solution in my office with a tree nodes 
cluster.

Oggetto: [Xen-users] Storage 
  questions

  Hello,

I am looking to set up a Xen array of servers 
  and I don't really know how to set up the storage subsystem.

I have 
  been looking for a little while and two options stand out for my setup. The 
  problem is rather simple, I need a pool of servers to access a shared storage 
  ressource.

The first option is the easiest, NFS. 

The second 
  option is a little more complex in appearance. I won't be able to have enough 
  budget to buy a SAN so that is out of the question. What I could do is have a 
  storage server with a bunch of disks. I would GNBD (or some other Network 
  Block Driver) coupled with GFS. I am pretty new to these two concepts. I know 
  that GNBD cannot be used alone if I want more then a single server to access 
  the storage space.

What is more interesting with performance in mind ? 

Thank you in advance for your input,

Antoine
