Hi Jack,
A lun is for WAFL just a file, so the snapshot is similar as by a file
and is a part of the volume.
We have always a separate NIC for our I-scsi traffic. On the filer and
also on the server (we use I-SCSI for our SQL servers (PeopleSoft and
others applications) and our exchange servers). When you use the same
NIC for all your traffic, on havy load, you can get some delays. This is
important when you have a high IO application and response time is very
important.

Onderwerp: Implementing ISCSI
All,
We have a FAS960 with ~2TB and we are going to implementing ISCSI for a
specific message application (Not MS Based). I am trying to understand
how
snapshots work with ISCSI.
Say I have a 400 GB volume with a 200GB lun. When a snapshot is taken,
are
the snapshots stored in side the lun or in the volume. (I think is in
the
volume?)
Also, we currently have a Quad GigE card in a GigabitEtherchannel.
Should I
use the ISCSI over that GigEtherChannel or should I dedicate a GigE
card.
Thanks
Jack
