What's the difference in all these? I've used SCSI and SSA for
a long and am happy with SSA. I'm trying to convince management
to get me (the company) a big thing like the DS4500, but I'm
confused just where SATA fit into the big picture.

Is SATA to be the next, big storage interface/protocol?

Standard EIDE/ATA....you've heard of that.  Just take that and put it on a
fancy new thin serial cable and you've got SATA.

I did forget to address your query re: iSCSI. iSCSI is a storage
architecture based upon transmitting SCSI packets over an IP network. Unlike
FCP SANs that have issues of interoperability between vendors, iSCSI is a
ratified open standard by the IETF. You can set up an iSCSI SAN with minimal
regard to server or networking vendors. In any iSCSI topology you will
require a target and initiator. Most initiators are free to download ie:
Microsoft
http://www.microsoft.com/downloads/...3c1a-15d6-4585-
b385-befd1319f825&displaylang=en.
You will require however some storage subsystem or gateway that provides the
target. NetApp includes a no charge iSCSI target with their product. Other
vendors include: Stonefly, Nexsan, FalconStor (not my favorite).
With iSCSI you can present an iSCSI LUN to an application server. iSCSI is
nice in that it functions as a block device allowing databases and mail apps
to be utilized.
My opinion is that iSCSI SANs will be the BIG storage growth market in the
next couple of years. Any one who can spell LAN or WAN should be considering
it.

And i just noticed that noone mentioned SAS.

SAS is Serially Attached SCSI, basically a SATA interface with a couple of
extra features.
