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.

Best regards,

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
