SNW Dataram Meeting Update
Dataram was the first of three vendors that we met with that does adaptive tiering, which is the process of moving data automatically to the most appropriate tier of storage, based on need. The primary focus for these tiering technologies is to move the most active data into high speed RAM or Flash based SSD. We feel that these devices are critical to SSD and will accelerate the already rapid adoption rate of the technology.

Dataram's XcelaSAN is unique in that it works on block I/O storage. The other solutions we have seen are focused on file based or NAS storage. Dataram has a 2U appliance with 8 fibre channel ports and 128GBs of RAM that caches. The appliance is inline between the storage and the switch, but users in an H/A SAN configuration, which should be everyone, should be able to implement redundant XcelaSAN's with zero downtime.
Once implemented the user selects which LUNs should be cached by the XcelaSAN appliance. For example you may want to cache your Exchange, MS-SQL and Oracle LUNs but leave your file server LUNs alone. The net affect is a significant performance increase, any data served from cache should see benefits from a roughly 450,000 IOPS performance boast.
