Currently NetApp has a two-pronged flash strategy. The first is to have flash caches in its array controllers, the Performance Accelerator Modules (PAM). PAM I is deliverable …

Pre-announcement of a pre-announcement?

Am I reading this right - are NetApp making a pre-announcement of an announcement that they *will* make by the end of the year announcing that SSD *will* be available for their arrays?

Hmmmm...... too little, too late I think.


Netapp's got this exactly right...


"PAM II was announced last Friday and provides up to 4TB of single level cell (SLC) flash for a controller. It accelerates read I/O for everything in the attached array that is accessed through the controller."

This is exactly the right way for NetApp to use Flash, and a SAS SSD would be exactly wrong. Netapp is a NAS vendor after all, why on earth would they incorporate Flash as a SCSI block-device on SAS when they can put it on the (orders-of-magnitude-faster) processor local bus???

I'm guessing NetApps pre-announcement is just there to quiet down the unknowing folks who don't yet understand why it's really dumb to put fast silicon storage behind a serial SCSI inteface.
