Compaq Arrays That Allow Read Only LUNS?

Do any of the MSA500 / MSA1000 / MSA1500 RAID controllers give you a way to
define a LUN as read-only to a host computer? I'm using this to provide a
large group of files to three computers that get updated maybe once a month.
Sure I could use a network share, but would for performance reasons like to
do this on fibre channel if it can be done.

not that I am aware of ... I have never had a requirement to set something
like that up.

i re-read this ... you cant do this with windows. and besides, of you had 3
hosts hitting the LUN via a single fibre connection, wouldnt you have the
same (imaginary) performance issues as you would have with your network
share?

Just set it up on one machine, and highly-connect the other hosts to the
same switch ... GigE with LB via LAN Teams ... should be fine.

I've seen it done quite common for video servers and for gaming with
multi-machine setups.

You can do this with Windows XP and Windows 2003 but could not with Windows
2000. You have to mark the volume readonly in Windows and now after some
fixes it acts correctly.

One reason I need this in fibre channel (or iscsi) is that I need the volume
to be seen as a local Windows device so that I can use junctions to organize
separate LUNs into a single file tree. The network has other traffic on
it, and the disk access I need will be quite intensive so having a separate
channel for that would be desirable.

Yes, worst case I'll use the network. Just checking for alternatives.
