...world of hosting Windows DomUs on our Xen infrastructure. As Windows generally requires a lot more IOPS than Linux does, we are trying to do everything we can to improve performance. While using SSDs would solve the IOPS problem, SSDs suffer from limited write cycles. So, we have the idea of using Flashcache from Facebook to use a single SSD as a cache in write-through mode, along with spindle drives in RAID10.

Hi, Has, or does, anyone use dm-cache - specifically for caching SAN based storage locally? I''m looking for a way to speed up SAN based storage on a CentOS 5.6 + XEN Hypervisor which uses iSCSI mounted SAN storage. dm-cache seems like it do the trick, but I''ve never heard of it before until someone mentioned it in another mailing list. A quick search on google didn''t

...is running a critical MySQL operation on BTRFS that could comment on their experience with it? "critical" to me means a 24x7 operation with 3-4 nines uptime requirement. Also, as BTRFS doesn''t seem to have SSD acceleration features yet, is anyone using BTRFS in combination with flashcache? Anybody who''s come to BTRFS from ZFS would be very helpful too.
