What is the iSCSI performance like?  Are you using iSCSI HBAs or are you
using software based initiator?  Also, how does it compare to 4gb FC?

I'm im the middle of a NetApp FAS 3020 SAN implementation and we are also
adding Dell Blade 1955's..  I have 2 separate units, primary site and
colo/DR site.  The primary site is a clustered box.  That means there are 2
separate controllers which talk to each other.  I have 2 disk shelves right
now with 14x144FC drives and I have 2 QLogic SANBox fiber switches.  


I have a couple servers hooked up iSCSI, a couple rack servers Fiber
connected (2 ports per server) and the Blade center has each blade fiber
connected with 2 ports.

 

Each fiber connected server/blade has 1 port going to each QLogic switch.
The QLogic switches themselves are not uplinked to each other.

 

The controllers have dual ports for their disk shelf and fiber switch
connectors.  She each one is connected to each shelf/switch, but in an
alternative port setup tob asically create a large redundant loop.  It's
complex to explain without a diagram, but you end up with a big mess of
cables with a fully clustered and redundant setup with no single point of
failure.

 

My DR site is not clustered like this, it's just single controller/fiber
switch.  The redundancy only comes from any directly connected fiber HBA's
with 2 ports, or iSCSI servers which have teamed NICs.

Can you do a quick spec of what it roughly looks like to have redundancy
with the SAN?

You can build tremendous reliability and redundancy into SAN appliances,
if you so chose. Multiple RAID disks, hot spares, redundant controllers,
network paths, etc.

Blades + SAN is our current direction, although we are just getting
started on implementation.

How much trust would you put in going with all blades for servers with
SAN solution?
Is this still not ulitmately a single point of failure on the storage
side if the RAID there fails? Any stats on actual reliability?
