Robotbeat, it won't allow you to use your own SSD.

The X25-E they use, is using customized firmware. Unless you can get hold of the firmware itself, and flash it to a fully compatible X25-E drive (let's say X25-M?), you won't be able to leverage on the new cache family

Given the SSDs I'm holding, I can try to do this trick for you, but for sure, it may violate warranty or even the UELA.

I got a call few weeks back from Adaptec, for trying this new toy out. It is quite an independent cache. You plug it in, it will auto recognize it as a cache, you plug it out, no more cache, that's all. No impact in your underlying data of the original disk array. My question is, if I am already running quite a number of X25-M SSDs rocketing fast @ up to 2GB/s read & 1GB/s write kind of performance, what is the impact of a single drive cache with 250MB/s read & 170MB/s to my existing set up? Perhaps that depends on the main difference in using a 512MB DDR2 cache vs additional 30GB secondary cache, uhm...sounds like what netapps is pushing their customers to "upgrade" lol!
