Oracle and SUN When it comes to dealing with storage, Solaris 10 provides admins with more choices than any other operating system. Right out of the box, it offers two filesystems, two volume managers, an iscsi target and initiator, and, naturally, an NFS server. Add a couple of Sun packages and you have volume replication, a cluster filesystem, and a hierarchical storage manager. Trust your data to the still-in-development features found in OpenSolaris, and you can have a fibre channel target and an in-kernel CIFS server, among other things. True, some of these features can be found in any enterprise-ready UNIX OS. But Solaris 10 integrates all of them into one well-tested package.

"ZFS is not a pure-play log structured FS and requires no cleaner.

That's an interesting statement. Can you tell me where I can more information about the fact that ZFS doesn't require a cleaner ?

Check this out:

By saying that it doesn't require a cleaner, what I had in mind is that it isn't background garbage collected and does not treat the disk as a circular log of segments that are either clean or dirty. It is more like a versioned tree of blocks. By cleaner I mean an asynchronous daemon that eventually "gets around to" cleaning segments that are dirty.

However, I am always willing to learn something. Do you think this evaluation is incorrect?
