Microsoft actually use Veritas technology here and there. The shadow
copy feature is Veritas. It says so.

My memory is Veritas did developed vfx for Windows, but it did not
provide a significant improvement in speed or reliablity over ntfs.
Veritas choose not to bring it to market. Who wants to stand up to
Microsoft Marketing anyway.

I think the rational is MS would have to allow Veritas the ability to do
VxFS on Windows, which I doubt they're inclined to do. It's probably
not a matter of Veritas wanting to do it, but more a matter of MS
allowing them to. I mean they could release a VxFS for windows right
now, but there would be no assurances that upcoming patches from MS
wouldn't break it.
When we use SFW, it's primary function is DMP. The secondary is the
better volume control than with LDM (win2k win2k3). Haven't worked with
MDM in win2k8. It also makes mounting volumes with out a drive letter
easier. In the 5.x versions, you do have flash-snaps, fast file resync,
and that kind of stuff, which is handy for offline backups of
exchange stores, for example. The MSCS support is also pretty good.
Plus VXVM does much better I/O stats than windows natively does so you
can get better I/O tuning as well. It also makes storage management
uniform across both platforms.
You can make win2k3 boot disks into dynamic disks via SFW but there's
some caveats and 'gotchas' (clearly documented in the admin guide).
In win2k8 the boot stuff has changed and it isn't possible (or necessary
IMHO) to do it via SFW. The native win2k8 tools are sufficient and it
keeps the support issues regarding booting under the MS umbrella.
So if you're already a Veritas shop, adding windows hosts to the mix is
a reasonable idea. If your a windows only shop, it might not make
as much sense. If I have one piece of advice, i'd be this: If you
have any issues that involve storage in any way, open the Veritas ticket
first, MS second. It's been my experience that MS will quickly plop the
ball back into the Veritas court if there is so much as a hint of it
being a SFW related issue. 2nd, the Veritas folks are fairly sharp and
can rule out Veritas as the issue fairly quickly so you go to MS with a
lot of answers in hand.
Cheers,
Rich
