Right, but the question was what's it all about. The SSD stuff is fairly robust, at least in the last couple of years. Burn-out is a concern but that's why you raid it; run mirror'd SSD Lun's. It's expensive for sure but if performance is everything you can get it in spades.
For several years now you could get this kind of performance elsewhere; Sun comes to mind immediately. So if availability was less of a concern and you were a speed-freak, Sun owned Netapp by very large margins. And with other vendors pushing the availability envelop and creeping into Netapp's sweetspot, along with all the other features they've been using to entice buyers, Netapp had to do something.
I think it's a great move. The capability is probably needed by only a small portion of the population but that portion has a lot of money to burn on performance.

..until you burn out the SSD.
Although, thats getting better, but at much greater cost as well.

Think about it like this. An SSD volume can provide ~1M IOPS and come in sizes of up to 1TB, maybe larger since I last looked. Add in Flexshare and you can basically stop time.

Hi all,
there are a lot of rumors about Solid State Drives...or SS Disks...alfo if there are no 'disks' at all inside :)
I've read some docs from NetApp and other SSD vendors.
NetApp says they support them in vFiler (so that, as native disks also? considering that vFiler nowadays can work in mixed mode) but there aren't tech specs, availability, configurator does not provide them...
So, what's about all this?
Regards,
