We have excellent results with Equallogic. We have had a SAS brick in
production for a year now and have just gotten another 16 TB SATA brick
to add to the array.<br>
<br>
The great thing is that as you add more storage you add 3 more GigE
interfaces, thus increasing your bandwidth to the array as a whole.<br>

EqualLogic makes iSCSI systems that are attractively priced relative to<br>
Dell's PowerVault line. In fact, Dell now owns EqualLogic, but they<br>
have yet to merge the product lines. (I suspect they're waiting until<br>
the OEM agreement with EMC expires :-) For that matter, I think.the<br>
Dell/EMC AX150/AX150i are still cheaper than the MD series...<br>
<br>
Also, remember to consider the Coraid EtherDrive: the SR1521T EtherDrive<br>
Storage Appliance is a good deal, if you don't need a rack-mount<br>
device. Warning: THEIR PRICES DO NOT INCLUDE THE HARD DISKS!! <br>
(Granted, hard drives are cheap enough that they won't be an<br>
overwhelming cost component, but...) Also note that contrary to popular<br>
belief, the EtherDrive Storage Appliances *do* implement "hardware"<br>
RAID. I don't know if it's truly "hardware" or - more likely - software<br>
running on an embedded controller, but that doesn't really matter, as<br>
the RAID function is completely separated from the host that's accessing<br>
the disks, just like any iSCSI or FC or SCSI RAID solution...<br>
