Is anyone running either the newish Adaptec 5805 or the new LSI (3ware) 9750

The low price of these cards makes me suspicious, compared to the more
expensive pre-merger 3ware cards and considerably more expensive Areca
ARC-1680.

Does anyone know off hand how to bind iscsi enterprise target to two
distinct addresses. Lets say I have a machine that has a bunch of
interfaces on it, with different subnets. Rather than have ietd
broadcast itself on all interfaces (the default), I would like to
limit it to only two interfaces.
The formula that ended up working for me:
undo modifications to udev rules
comment out the alias ethX lines that anaconda had placed in my modprobe.conf
use HWADDR= in the ifcfg-ethX config files.
slave interfaces have onboot=yes in them, despite no IP address information
The nics are correctly i

Les,
That's pretty much my problem. I was hoping to kill two birds with

So the short answers are:
1) centos/redhat possess no built-in means of block-level replication
via GFS / RHCS
2) openfiler provides some manor of block-level replication

be a good idea for production (drbd)
