Hello Jeff,

I don't have 1) 2) or 3) running in my shop, however my understanding is
that you need iSCSI adapters to make it work. A normal NIC isn't going to
do the job since a iSCSI adapter offloads the TCP overhead like a SSL
accelerator does.

Subject: SAN question/iSCSi -offtopic?

hopefully, this not too off-topic. I ask this because mostly AIX guys
own
the sharks and fabrics in their environments.
I was in an IBM/cisco kickoff meeting today, the main focus was the
cisco
SAN switches/director. however, iSCSI came up because that seems to be
Cisco's big advantage in this arena.

my questions:
1. Is anyone using iSCSI under AIX or M$? according to the cisco media
hype, AIX is supported

2. is anyone out there presenting LUNs from a 2105 to a cisco 5420/5428
storage router ?

3. if you answered yes to the previous 2 questions..Is anyone mirroring
LVs
(or disk in M$ world) across both fibre channel and IP? I ask because it
makes a lot of sense in the Microsoft world. I could cut my connection
cost
in half If I only needed 1 HBA in the host and for failover I used the
10/100/1Gb NIC. I am uncertain how load balancing/sharing would work via
SDD, but I assume I could tweak it so that only the FC HBA would be
taking
disk requests until /if there was a failure and I could then offload
traffic
via iSCSI.

any info on your experiences would be greatly appreciated.
