Re: Netapp Contract / Support questions
by Blackmor, Chris 21 Oct '09

I agree with Matt. USUALLY we get outstanding support from NA. We also track people we work with and keep an informal ranking system. +5=walks on water to -5=hang up and try again. We are a large shop with more than 140 filers world wide. This equates to a lot of interaction. Yes, we pay out the nose for support but we usually so pretty well with them. In the instances where your engineer is falling flat remember two little words... Duty Manager As far as tier 1 support, I have not found a large company that has quite met NA's bar but there is always room for improvement.

I think the one thing that netapp support does require in some situations, similar to some other vendors, is proactive effort on your part. Netapp has a bunch of very bright technical people, but support can be hit or miss. If you feel like your support engineer doesn't care or doesn't want to help (hasn't been my experience) or is just not understanding the problem/resolving it fast enough (definitely seen this), escalate. And netapp, as opposed to other vendors I work with, will come through for you. You'll get someone from engineering on the phone, or a service manager, etc. You can argue that you shouldn't have to do this, and in a perfect world, I agree. But whenever I or a customer of mine who is a netapp shop has been in a bind, netapp has delivered. I think that's worth something. There are third party companies that provide netapp support, but other than for basic parts replacement on legacy systems, I can't recommend them.

Netapp Contract / Support questions
by Rasta Surfer 20 Oct '09

20 Oct '09

We're a small shop a couple of FAS 3020's doing basic, NFS, CIFS, Snapdrive/SnapManager For SQL and Snapmirror. We are up for our contract renewal soon. I have been in the biz for quite a number of years and can remember back to amazing support from Netapp. I have found quite the opposite over the past two years. Most are problems with first addressing the case, usually it took a phone call. Then it gets to incompetence with their products, like SnapManager for SQL and Snapdrive. Cases went on forever, i always had to hound them for status, making it quite frustrating. The end result of most cases is me getting a note from some support manager at Netapp apologizing. I still like the products, just hate the support methods. What do you folks do? We of course want to upgrade when possible to keep up to date from bugs. We don't want to blow the bank though for their support if we can go somewhere else for better. tia for your thoughts, rsurfer

Agreed. The number of messages was small-potatoes in the grand scheme of things. "delete" works just fine. And folks, let's hear it for NetApp responding from Dave Hitz's level to something like this; I hardly think we could expect the same from that other storage vendor should the same type of thing originate from their domain. Thanks, Dave, for responding so quickly and taking the time to explain. Now, can we get SMB2.x support built in to 8.0.x? ;) *------------------------------------------*-----------------------* | Kevin Davis (UNIX/Storage Sysadmin) | Natick, Massachusetts | | 508.647.7660 | 01760-2098 | | mailto:kevin.davis@mathworks.com *-----------------------* | http://www.mathworks.com | | *------------------------------------------*-----------------------*

Linux/MySQL instances on VM/ESX
by Rob Borowicz 19 Oct '09

19 Oct '09

Howdy all, I'm new to the ESX arena and have been consuming CentOS instances on several ESX servers in house. These CentOS instances are an appliance image my company makes that runs a potentially busy MySQL db. We have so far been using only locally attached disk, but I'm thinking filers rock using NFS to ESX host, and most probably there is a best practices guide published by Netapp. I no longer support filers and as such don't have a NOW account anymore, but am curious to how well filers support ESX datastore requirements. Could anybody advise me on what the standard practice is? Direct attach GigE links from the filer to the ESX host and run NFS? How many instances of MySQL can you get away with on an ESX host mounting filer volumes? TIA -Bob B.

7.3.1 simulator missing domains info?

I'm looking at the statit output on a sim running 7.3.1 and I'm not seeing the Multiprocessor statistics that includes domain info - could anyone who's running 7.3.1 confirm that it either exists or has been removed?

wafl realocate unable with snapshots
by Chaim Rieger 12 Oct '09

12 Oct '09

according to netapp, i can not do a reallocate if there are underlying snapshots, the issue is that the snapshots are for a large (3TB) oracle db, and will not be rotated off anytime soon. is there a way around this ? any ideas ?

VMware + (Linux) MySQL on NetApp
by Filip Sneppe 06 Oct '09

06 Oct '09

Hi, I am wondering if a lot of people out there are running VMware virtualized Linux MySQL machines on NetApp storage ? Any thoughts on how to configure things to get the best performance ? What are people generally doing ? - database on vmdk file in VMware datastore (and from ESX using either NFS, iSCSI or FCP to access the datastore) - NFS mount of a NetApp volume from the Linux MySQL machine - iSCSI LUN mapping from the Linux MySQL machine - FCP LUN mapping (via Raw Device Mapping in VMware) Any thoughts and recommendations ? Thanks in advance! Best regards, Filip

High CPU utilizations and file I/O
by Milazzo Giacomo 05 Oct '09

05 Oct '09

Hi all, From some days the CPU of a 3020C reaches 100% slowing down all processes. Maybe some area of a 3020HA is stressed on I/O. There's a VMware on NFS farm using both servers and VDI also! The customer states that in the NFS volume for VMware there's an high activity of continous destruction and building of VMware vdisk... Is there some tool that can let me understand which volume is under stress and in case move it on the other head? Or maybe this filer is undersized for the job that has been asked... Regards, Dott. Giacomo Milazzo [cid:image001.jpg@01CA42BC.89037330] Technical Account Manager Sinergy SpA Filiale di Roma * 00148. viale Castello della Magliana, 38 ' (+39) 3406001045 0665970252 7 +39 02 26922048 * Giacomo.Milazzo(a)Sinergy.it
