Hello ZFS folks, with the deployment of HA-ZFS we are in the process of migrating some SVM based cluster services to ZFS. What we couldn''t find is an up-to-date performance comparison between Oracle''s own ASM technology compared to ZFS performance, I could only find performance figures from 2006... (http://blogs.sun.com/roch/ , http://blogs.sun.com/realneel/entry/zfs_and_databases ) Should we give up on this one and rather let the Oracle database clusters remain on SVM/raw devices? (depending the perf. difference we might just convince the customer using the extra features zfs can provide..) Can zfs provide raw access to disks , in case the client would still insist on ASM ? I have found a blog where they say zfs does not provide raw disk access at all, but what about "zfs -V" -> create a raw device for swap ?
