You are right, NetApp likes to call it CoS, for Control of Service. Glenn knew this, I think it's just easier to say QoS, and assume everyone gets how it *really* works.

Glenn, Not sure QoS is the right terminology. QoS implies some kind of service or performance guarantee, even NetApp disavows any guarantees with Flexshare. But it is cool...

Blake,
Flexshare - is this the 'guardrail' technology that enables QoS of particular datasets? Or is that 'future' at the moment?

We are testing it as well. FlexShare looks to be some killer technology we are excited to look at. But the mutliproc changes I think are key to this release. Which almost makes me want to wait until 7.2.2 or 7.2.3 before thinking about it seriously. Because if it's good now, wait until they perfect it!

Not yet tested, but they did fix CIFS running on only 1 proc at a time
(now
multithreaded and shouldn't be an issue with competing for resources

WAFL anymore). Looking forward to that, especially with changenotify
and
other issues that can cause problems on older systems!

I noticed that Netapp GA'd 7.2 on the 3rd of August. I did a bug fix
report
and noticed that a lot of CIFS bugs were fixed between the GD release
7.04
and 7.2. I also noticed the same thing when I compared 7.1.1 and 7.2.
I've
also heard that CIFS performs a lot better on multiproc systems with
this
OS. Has anyone tested this out under a load and does the OS provide
better
CIFS performance without any reliability side affects or impact to
other
protocols such as NFS? I have it installed on a test system but I
don't
really have a load on it yet.
Thanks
-Mark
