Netapp and VMware... It's all so confusing!
by Timothy Hollingworth 01 Apr '10

01 Apr '10

So, say for example, I want to virtualize an Exchange server. Lets also say that I want to manage it via Snapdrive and SME. Lets also say, just for the heck of it, that I want both the new front-engined Acura NSX as well as the Porsche RC3. The cars aside, I would have to run iSCSI from within the VM, install and use Snapdrive from within the VM to provision LUNs, install Exchange and then use SME? It seems kind of silly to use iSCSI from within a VM if the ESX box were fiber attached to the Filer, just to be able to use Snapdrive and SME, no? I would love to be able to use the features of SD and SME within a completely virtual environment and am wondering what some real world implementations other VMware/Netapp customers are running. Do you run storage for the databases and logs in VMDK's and manage snapshots and backups from a VMware virtual machine perspective or do you manage them as iSCSI LUNs and use SD and SME? Or am I completely blind and missing something? Timothy L. Hollingworth Sr. Network Engineer, ePlus Technology Inc. 678.462.6698 (cell) AIM: HollingworthTim YIM: t_holling

10k and 15k disks, sparedisk handling
by Willeke, Jochen 28 Jan '09

28 Jan '09

Hello toasters, i came accross an issue with one filer where we have mixed 10k and 15k 144gb disks. Due to the fact that netapp stops delivering 10k FC disks we are running out of 10k spares for that filer. We had the issue that one 10k 144gb disk failed and the filer had the choice to take a 15k 144gb or a 10k 320gb disk. Gues what, the filer chose the 320gb over the 144gb one because of the better fit in RPM. Now my two questions are, will this behaviour change?? And can i stop the filer from complaining about low spares?? As 10k 144gb disks are not available any longer, i am afraid to receive this message for quiet a long time (till we got rid of all 10k disks). Best regards from germany and thanks in advance Jochen -- WINCOR NIXDORF International GmbH Sitz der Gesellschaft: Paderborn Registergericht Paderborn HRB 3507 Gesch�ftsf�hrer: Eckard Heidloff (Vorsitzender), Stefan Auerbach, Dr. J�rgen Wunram Vorsitzender des Aufsichtsrats: Karl-Heinz Stiller Steuernummer: 339/5884/0020 - Ust-ID Nr.: DE812927716 - WEEE-Reg.-Nr.

Performance numbers for FAS3140?
by Davin Milun 27 Jan '09

27 Jan '09

Does anyone have any performance numbers (or impressions, if not actual numbers) of the FAS3140? NetApp does not seem to have published any on the spec.org site - they have the 3040, 3070 and 3170 - but not the 3140. I'm curious how the 3140 compares to a 3070, and to a 3170. I'm mostly interested in NFS performance - but I expect that all protocols should scale similarly-enough between models for comparisons of any protocol to be useful. Thanks. Davin.

Re: panics with 7.2.6.1
by Jack Lyons 24 Jan '09

24 Jan '09

Are there any other people experiencing issues with 7.2.6.1? We put off our upgraded based on this thread, but I still see 7.2.6.1 on NOW. Was this possibly a 7.2.6 issue that happened after an upgrade didn't complete correctly? Peter D.

RE: 7.3.1 and 2020 nonsense :-)
by Glenn Walker 23 Jan '09

23 Jan '09

That was my point - having spares is always a good idea and I don't consider it 'waste'. This means the root volume will waste a few GB, like any other volume.

The issue is for this nonsense 2020 usage of 7.3.1. For 2020 and 16TB aggregate only: you must create a SEPARATE aggregate raid dp that will have to contain THE ROOT ONLY, no other volumes, no user data. If you want you could also use R4...but with 2 spares. The result is the same. For a 2020 using 1 TB SATA disk I will waste 3 TB for root!!!

Put all data in the one aggregate. We (as a general rule) do not use a separate aggregate for our root volumes - we just maintain a healthy number of spares and use RAID-DP. Glenn ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Milazzo Giacomo Sent: Tuesday, January 20, 2009 7:09 AM To: toasters(a)mathworks.com Subject: 7.3.1 and 2020 nonsense :-) Hi all, reading this from 7.3.1 release note I've been really beated from this. I was thinking to a 2020 full of 1 TB SATA. To have a 16 TB aggregate I should waste 3 TB for few gigs of root! :-) Luckly I don't think that somebody will suggest a 2020 to manage 16 TB of data!!! :-) Bye Increased aggregate capacity for FAS2020 systems Beginning with Data ONTAP 7.3.1, FAS2020 systems support aggregates up to 16 TB raw capacity, provided that the root volume is hosted in a dedicated aggregate (that is, one that contains only the root volume and no user data). Note: An alternative to maintaining a dedicated root aggregate is to maintain two spare disks. A dedicated root aggregate configuration of three disks is the recommended best practice for all systems. However, if such a configuration is not practical in your environment, you must maintain two spare disks if you configure your FAS2020 system for aggregates larger than 8 TB raw capacity. If you do not configure aggregates larger than 8 TB raw capacity on your FAS2020 system, the conditions for two spare disks or a dedicated root aggregate do not apply. For more information about FAS2020 systems' storage capacity, see the System Configuration Guide. Dott.

Fas270 iSCSI performance
by Amateur-FASadmin 22 Jan '09

22 Jan '09

Dear Group I have some performance issues using the following. 1 SAN IBM N3700-A20 (Fas270) 2 IBM x3650 each with two Qlogic(R) iSCSI Single Port PCIe HBA for System x ESX 3.5 1 HP 1800 Gb Switch When I use IOmeter from a W2K8 ESX VM I get only 18mb/sec using IOmeter setup from Vmware forum speed guide. Regardles witch server I run this from. But when using MS-Software iSCSI from physical W2K8 box connection to SAN I get around 40 mb/sec. As I see it. It is not the SAN or SW performance or ?? I have searched the Internet for any answers but have not found any usable. Can you give me some hints to go by ?

changing cfmode question
by Romeo Theriault 21 Jan '09

21 Jan '09

We are going to be getting some new heads for our cluster. The new heads are going to require that the cluster use a single_image cfmode. We currently are in a partner cfmode. I am wondering if we are going to need to stop all traffic to the filers (nfs, iscsi) when we change the cfmode or can we just stop all the fcp traffic to the filers and do the cfmode changes while the tcp traffic to the filers continues? I seem to find conflicting documentation on this. In the "Changing the Cluster cfmode Setting in Fiber Channel SAN Configurations" pdf they don't mention anything about having to reboot the heads but in one of the knowledgebase articles talking about having to change the cfmode, they state: "Reboot any system on which this change has been made." https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb32682 Thanks for any help. -- Romeo Theriault System Administrator Information Technology Services

Hi toasters, I've got the following output from snapmirror status (no entry in /etc/snapmirror.conf !): Source Destination State Lag Status FILER:vol11 NEARSTORE:sm_vol11 Broken-off 13:19:28 Idle Now I take the destination volume offline. Another snapmirror status results in: Source Destination State Lag Status FILER:vol11 NEARSTORE:sm_vol11 Snapmirrored 13:19:28 Idle Can anyone explain this "odd" state change ? BTW.
