One of the Gardner briefings that I have read mentioned specialized
adapters. I don't really know, but I wasn't interested in iSCSI as a
result. Fibre Channel was much better suited to my needs and that is what we
have installed.
I am simply passing the limited information that I have on and hopefully if
it is wrong then someone can correct it.

is this true? my understanding from cisco docs indicates that any NIC
that
supports PXE will support it. dedicated adapters would make it nearly
useless.
I have to question this. I haven't seen an iSCSI adapter on the market.

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.

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.
