We aren't using FAST on any of our CXs, but we'll soon be implementing the equivalent on some of our Equallogic gear. We have a couple of their new 'hybrid' shelves on order (some SSD and some spindle) and we'll be using it for that. Equallogic does analyze I/O and "automagically" move the data to the 'sweet spots'. We did just implement a shelf of EFDs on one of our CX4's. We split it between our 2 biggest SQL servers. We've seen some pretty significant performance gains, but yeah - they were not cheap for sure. Jim

I'm looking for some real world feedback on how it functions. I remember reading a little bit into FAST (Fully Automated Storage Tiering) when EMC first announced it and from what I read, it didn't seem as "automated" as the acronym made it sound. It seemed like you had to manually review NaviAnalyzer results and manually move data based on the recommendation from the performance analysis. Anyway, we're looking into EMC's EFDs for our CX4 but I certainly can't justify the expense if the drives are going to be implemented on a per system basis, or requires that I manually identify hot spots and move LUNs accordingly. If the new version will actually move blocks of data based on IO rates I'd be willing to give it more serious thought. Also, I've love to hear any feedback from those of you that have implemented Fast Cache. - Sean ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin CONFIDENTIALITY NOTICE: This email, including attachments, is for the sole use of the intended recipient(s) and may contain confidential and/or protected health information.
