Bryan, Thanks for the response! Appreciated.
As I expected, really. I'm trying to solve a problem with a large archiving solution at the moment and attempting to see if I could leverage the 7000 series as the centre-part of the equation. The premise of attaining great performance through SSD for meta slices was enticing. Architecturally, I don't think it is the right 'fit' for what I'm attempting (shared SAM/Q pools, with meta data slices on the FC loop sitting on SSD - with underlying cache disk controlled via ZFS for QFS clients and meta controller to see on multiwriter/multiread configuration). This doesn't work, as a result of ZFS's multi mount/non concurrent mount limitations. I.e - you could never have the filesystem mounted in more than one location, notionally, at any one time. Currently, a multi-reader, multi-writer, it is not! I guess it brings me to another question really. Is there, or are there any plans or considerations to one day somehow bring a multi-reader/multi-writer model to ZFS? Maybe it goes against design principles to begin with, and as such, isn't really a sensible possibility? Thanks anyway! z -- This message posted from opensolaris.org _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
