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,

from what i know some netapp filers have ssd's for vol0 in the near future, there will be a filer released that is all ssd,
What's it all about? Performance. Blazing fast performance.
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.

It depends though:

I don't have hands on experience with SSD, but thought that was an eye opening article...theres a time and place for SSD it seems: seek heavy ops (boot disk, DB index) are excellent, seq: not so good.

Hmm, they're classifying SSD as flash only. Perhaps that's the case but I was thinking along the lines of Texas Memory's RAMSAN. Battery backed DRAM, much like Netapp NVRAM. I don't think flash mem gets anywhere near 1M IOPS...
Netapp supports the TM RAMSAN. Or will with an PVR.
