AV Scan Engines

Does anyone have any info on AV scan engines that are available for Netapp? We have been using Symantec but are wondering if any of the other vendors do a better job. -Mark

I've used TrendMicro and had no issues. I am curious with the issues that you've had and what version of TrendMicro you were running. Just something to be aware of in case I run into it.

We use Trendmicro, and are migrating to MacAfee (corporate standard). The only problems with Trendmicro we had were all Windows authentication based issues (AD migration, password expirations, etc). Our MacAfee scanners aren't in production yet, so no comment on them.

RE: Hitachi SAN Systems

Agreed on the EMC comment. Thanks to all that have responded to my initial question regarding Hitachi Systems. -----Original Message----- From: Glenn Walker [mailto:ggwalker@mindspring.com] Sent: Thursday, March 16, 2006 10:48 AM To: jeff.mery(a)ni.com; Linux Admin Cc: bjacobson; Kristian Ejvind (KI/EAB); owner-toasters(a)mathworks.com; toasters(a)mathworks.com Subject: RE: Hitachi SAN Systems Last I heard, Hitachi was no longer reselling the GFILER product. However, NetApp has considerable effort behind the V-SERIES (same thing, basically) which you can stick in front of pretty much any other SAN-based storage platform. I can't see that going away, and I'm sure it will still support Hitachi. I personally can't wait to see someone implement a V-Series NetApp in front of an EMC array... I'm sure that would make the EMC guys have a small kitten.

USP shows great performance. (to many to discuss, I am sure HDS sales rep will cover that) I just want to point out few obvious caveats (sorry HDS): No equivalent of toasters in HDS world (or any support forum/mailing list, etc.) Cryptic Documentation. To many GUI/CLI to learn (Storage NAV, Device Manager, HSSM, DUMP, DUMP CLI) 95xx can not delete LUNS (only last one you created) USP raid groups and basic config are laid out by HDS USP: can not touch it with HDS FE. USP: you loose 1 additional chip port for each external chip port.

My experience was that to get started you definitely need to have an experienced person close by to guide you through the terms and language. All written information is in "japaneese in english", so you have to think a little when reading anything. (Label on the box: "Be careful of the drop. It is heavy." Another label that I don't remember exactly, something like "HOT to the hand. Careful!" :) Management software is terribly slow, it takes ages to do anything. Booting the HDS is oh-so-slow (3-12 minutes). (Btw. at that time we moved from LSI to HDS, and the LSI unit booted in about 10-20 seconds! What a difference.) HOWEVER: once in place - the HDS rocks! Impressing speed, reliable, just what you want. For support I guess it depends on your local support channel - we were satisfied with our support, although we never had to consult them for anything more serious than disk replacements. /Kristian

And I just did some manual testing, and it's indeed the case that BugID 148982 caused NetApp to break the SNMP values in 6.5.4! :-((( So the once-useful SNMP cpuBusyTime is now showing the ANY time. They should have fixed that bug by fixing sysstat to show AVG, not by fixing SNMP to show ANY! Thanks for the heads up! I would have had the same "What's causing this 20% CPU spike!?!?" issue after my upcoming upgrades, if I had not had this discussion here. Davin.

RE: Mixed Mode
by Maglinger, Paul 15 Mar '06

Personally, although we run mixed-mode as a necessary evil, it is one of the most challenging tasks I have running the filer. I do wish they'd improve it. Just my 2 cents... ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Glenn Dekhayser Sent: Wednesday, March 15, 2006 11:54 To: JONES P.S.; Tracy Russell; toasters(a)mathworks.com Subject: RE: Mixed Mode In my 10+ years of dealing with Netapp, I have never known them to remove a feature from OnTAP, and can't imagine them starting now- especially one used by thousands of installations today. Perhaps your users misunderstood what they heard in training? A trainer would also never disclose that kind of information in that forum as presumably not everyone in the room would be under NDA, and that kind of information, if true (and I suspect not) would be confidential. ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of JONES P.S.

I have not heard of this remote possibility in any shape or form. We rely absolutely on mixed mode presentation to our users; its one of the keystone elements of our single authentication, single filestore architecture. Losing this would be too much to contemplate.

Several co-workers returned from NetApp training stating that this particular mode is not encouraged and may be dropped in the not too distant future from NetApp support. Has anyone else heard this or can confirm this to any degree? We are about to set up a new Filer and I'm trying to decide what to do with a volume that is currently configured for mixed mode security on an old Filer. If anyone has experiences changes from mixed mode to either all CIFS or NFS, I'd appreciate their inputs as well. Thanks. Tracy

SATA Performance Data

Does anyone have any SATA performance data? I know that there are many variables when measuring disk i/o, so any information would be appreciated. Thanks, -Carl
