RE: simple SAN?! - toasters

      You can use SD\SM with FC-SAN as well as iSCSI using software initiator
or hardware initiator (QLogic 4010C for example).
I'm not aware if using VMWare with guest OSs places any further
limitations on this.

You may also want to be aware of the limitations as to when and where
you can use SnapDrive and SnapManager products with the guest machines.
Essentially you can only use SD and SM if you are using a software iSCSI
initiator.  Any other methods (and as far as I know this includes raw
device mapping) and you won't be able to use them.

We already use ISCSI, but we aer thinking about VMWare and VMWare has
some nice features (e.g. VCB) which need an FC-SAN.
Thanks anyway

    If you are looking at low cost san, I would go Iscsi, as long as
everything you need on Iscsi is on Gig ethernet ports, it should work
fine.

    Hi,
     
    as we use not too much SAN at our site i am not really used to
this topic. Yesterday i read an article about "simple SAN". "Simple SAN"
seems to mean as an plug-n-play solution. But what about the components
espacially the SAN-switches?
     
    Do we see really new (and cheap :D) SAN-switches or only old
products "reassembled" as a solution for small companies.
     
    Regards
     
    Jochen
