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.

[q]I too am impatient with the state of Linux storage management. For better or worse, I just don't think it is a priority for the mainline kernel development crew, or Red Hat, which, like it or not, is all that matters in the commercial space. I think ext3 is a stable, well-tuned filesystem, but I find LVM and MD to be clumsy and fragile. Once ext4 is decently stable, I would love to see work on a Real Volume Manager (tm).

I think you wrong here. I do think the Linux kernel community is aware of the desperate need of a 'kick-ass-enterprise-ready-filesystem-like-ZFS'. A lot of people where waiting for the arrival of Reiser4, but we all know how that ended :-)

Ext4 is just a 'let's be pragmatic' solution: we need something better than Ext3.

ZFS for Linux is (besides license issues) a 'no-go' because of the (VFS) layering stuff.

But I think that there's hope: BTRFS. It doesn't sound as sexy as ZFS, but it has a lot to offer when it becomes stable and available. I'm following the development closely, and I get the idea that Chris Mason makes sure to not fall into the 'reiser trap' by communicating in a constructive matter with the rest of the kernel community.

Although not ready in the near future (read 2008), I personally have high expectations of BTRFS. And I believe it will become the default filesystem for many distributions when it arrives.
