Celerra with OS X Mavericks
Has anyone heard anything regarding Mac OS X Mavericks support for the Celerra? I have a VNX running 7.1.56-5 for File. I know that Lion had some major issues and I am hoping that Mavericks isn't as bad.
I got myself a developers copy of Mavericks and did some testing. From what I can see, SMB is much slower on Mavericks than Lion. Almost to the point that it is unusable. I was testing on 2 identical physical machines, one running Lion and one running Mavericks and performance on Mavericks was much worse. I was getting 10 MB/sec on Mavericks, compared to 90MB/sec on Lion. My windows machines get 115MB/sec or so. I wiresharked it and could see that it is using SMB2 but it is having alot of errors for some reason. Maybe this will be all fixed when they release the full version but yikes, this would really be a headache to optimize.
Is anyone else testing this or seeing this issue? I was hoping for it to be faster but I was fairly disappointed to see how slow the SMB performance was. Looks like a mavericks problem but it will become my problem once Mavericks is released!
Thanks

I have been alerted to this thread:

Has any testing been done with VNX File?
Thanks

The Google groups discussion you quoted sounds like bugs or at least changed behavior in the Apple SMB client implementation.
Yes EMC is doing testing with Apple clients as well and is participating in the Apple beta program.
I have not heard about specific bugs fixed on our side.
I would suggest to look into the release notes for the VNX OE service pack after the Mavericks release.

Does EMC currently have any OSX 10.9 Mavericks users working with a Celerra file share?

I have more than 40 arrays deployed with thousands of Mac OS X users (10.6 - 10.9.2) accessing CIFS file systems. The hardware involved includes Celerra NX4/NS120/NS480/NS960, VNXe 3150, VNX 5300/5500/5700.
I don't believe there is an inherent issue with Mac users accessing shared file storage hosted on EMC NAS (Celerra or VNX). I believe Apple's refusal to be transparent and their resistance to support the most commonly available file access capabilities has created a very confusing and complex performance problem for some Mac users.
The summary is that Apple has been floating a reverse engineered homemade protocol to support some SMB function and they have been trying to force their own proprietary protocol instead (AFP) but have not made it clear to users of Mac OS X. So it manifests itself as weird unexplainable performance problems.
Once you understand what is supported in what versions it becomes more clear when to expect performance issues from a Mac OS X client accessing files on a CIFS server from an EMC Celerra or VNX.
RIght now Celerra only supports SMB 2.2 (renamed later to SMB 3.0) but not the most recent version of SMB 3. And Apple has provided some updates in OS X 10.9.2 but won't clarify exactly which version and dialect of SMB is and is not supported.
But if you have a VNX on current code and a Mac on OS X 10.9.2 it works great. It works well on Celerra current code and current OS X version. (For upgraded Mac's you may have to manually force SMBx above AFP to get any benefits.)
Even if EMC does push all SMB updates to Celerra code I can almost guarantee Apple will not put update into older versions of OS X.
Hope some of this helps.

update for what specifically ?
VNX supports SMB 3.0 now for quite a while
