Third party LR 10G networking.
by Jeff Cleverley 03 Sep '13

03 Sep '13

Greetings, We are looking at upgrading and changing our network architecture. One option would be to use LR GBIC with single mode fibre. This appears to require non-NetApp GBIC which I'm sure makes it unsupported. Is anyone doing this, and if so, which parts are you using and what issues have you run into? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

SAN vs Software defined storage
by Chris Picton 28 Aug '13

28 Aug '13

Hi all I am currently successfully using a fas3210 as 10g NFS storage for a vmware cluster I have in production. I am currently dedicating 2 shelves of 300Gb drives to vmware, and am getting very good response times. In my test environment, I am using KVM sitting on top of a moosefs cluster (6 machines with 5x 1Tb SATA drives each, and 1Gb network). Disk performance in the VMs is obviously not as good as 10g NFS, but is is definitely acceptable for my database/app servers/etc in test. I am considering my long term storage strategy (both capacity and speed),and I have two roads to go down in order to scale my storage to be able to handle 100s/1000s of vms. The first is to use netapp with large SATA drives for slow storage, and use high speed SAS drives for fast storage, choosing the storage type according to purpose, or I can use something like Moosefs (or more likely, Ceph) to provide a scalable storage cluster off "commodity" hardware, with SSD caching/journalling, and SATA drives for actual storage. Does anyone have experience with both traditional SAN storage, as well as Ceph/Gluster/Moosefs and is willing to share any thoughts/ideas they may have? Regards Chris

Flash Pool experiences with VDI?
by Sami Kapanen 28 Aug '13

28 Aug '13

Hey all, Who has experiences of using FlashPools for VDI storage? We are currently running approx. 150 VDI machines, using VMware View5. (..numbers will grow) Now we use EMC CX4 with FastCache and have managed with it. We deploy new VDI machines in advance to avoid boot storms, mainly using non-persistent machines. We are looking for new storage now and FAS3220 with FlashPools is one option. If you have some examples of your FlashPool configs and amounts of VDI machines running? So far we haven't used NetApp with VDI at all, just have one FAS2040 as CIFS filer for desktops, Sk

Metrics!
by Ray Van Dolson 27 Aug '13

27 Aug '13

We have a growing deployment with ~25 filers and about 750TB of usable space. Most of it is VMware datastore space exposed via NFS, but some is general purpose NAS file sharing. We've been using OnCommand Core (formerly DFM) to handle reporting and such, and for the most part it's worked pretty well. I need to start pulling together some metrics for the environment as a whole, both to benefit the Storage Team who manages the devices, but also to be able to pass along to my bosses so they can get a basic grasp of how things are going. I'm curious how those of you with deployments similar to mine or larger hvae dealt with this? What sort of things are you reporting on, and how do you handle the "roll-ups" to summarize many (in our case 200+) volumes into something meaningful? Are you generating reports natively from OnCommand Core, or pulling the data out into another tool? Do you find the OnCommand DataSets feature useful? We haven't really leveraged it properly I think. My thought is to present a sort of physical view of our environment showing roll-ups of storage capacity and performance (probably CPU, IOPS and latency). How to give a snapshot overview of the whole environment is what I'm not sure on. I'm thinking using the DataSets will help me organize our various types of data and then I can report on that. I'm not sure, however, if I should spend my time trying to get the right reports out of OnCommand Core directly or if I should just start extracting the data to another tool (which?) or into a database where I can home-brew up what I'm after. Thoughts/experiences? Thanks, Ray

Mapping CIFS user to Unix user
by Iluhes 22 Aug '13

22 Aug '13

I have a very strange issue. The share are exported via CIFS and NFS. System is connect to AD domain and NIS Sometime Windows user creates a file with correct UNIX id, sometime it create a file that is owned by nobody4:x:65534:65534:SunOS 4.x NFS Anonymous Access User:/: I see where it is coming from, first it is matched to correct Unix ID and the right away it is matched to pcuser.... On filer /etc/password pcuser::65534:65534::/: This is waht I see in the messegaes file...

configAdvisor question for CM
by Klise, Steve 22 Aug '13

22 Aug '13

* 6250's * DOT 8.2p2 CM; 2 node <FCP> * 3 stacks Is there a way to determine the port a stack is plugged into on the IO modules on the back of the shelves? I know I can trace them, but that's not so sexy. I have the in and out on the node side, but wanted to identify the other side of the stack. This is what I tried from each node, but the output was the same.

sis start -s causing system slowdown
by Chris Picton 21 Aug '13

21 Aug '13

Hi all One of the volumes exported via NFS from my fas3210 didn't have dedup enabled when comissioned. It is 250GB, and hosts ploop backed openvz vms. It is currently using about 210GB, and hourly snapshot size is about 6GB. When I run sis start -s on this volume, the entire system slows down to a crawl. My snmp monitoring start timing out, ssh access to the system is hit and miss, taking over a minute to log in, and when logged on, command response is sluggish. I also get the following error in the logs for all snapmirror pairs SnapMirror: source transfer from TEST_TESTVOL to xx.yy.zz:TEST_TESTVOL : request denied, previous request still processing. Fortunately, disk access from clients on this and other volumes are not detrimentally affected, but IO response times do go up by about 100ms. After running overnight for 11 hours, sis status reports Progress: 19333120 KB Scanned Change Log Usage: 88% Logical Data: 151 GB/49 TB (0%) At this rate, it will take about 5 days to finish scanning, leaving me barely able to manage the system effectively while this is happening. Is this normal behaviour - do I just have to wait through it, or can I stop it and correct something before trying again. Also, is the change log filling up towards 100% something to worry about? Regards Chris

need advice on using old FAS3140 for snapvault
by Scott Classen 21 Aug '13

21 Aug '13

Hello fellow toaster, We are contemplating an upgrade from our existing FAS3140 to a new FAS3220. The 3140 has served us very well and been unbelievably reliable, but is now 5 years old. We would like to move to a newer filer and more storage. What do to with the old filer and it's three associated shelves (DS14Mk4)? Could it be used as some sort of snapvault device? Currently we back up to LTO-4 tapes via NDMP, which is a bit painful, but we deal with it. I like the idea of having a set of backups on disk, ready to go, and easily accessible. We only use NFS and iSCSI functionality of the filer and have no extra licenses so I'm not very familiar with the day-to-day use of snapvault. Is it feasible to use the retired FAS3140 as a snapvault "container" without having it under an annual service contract? If we pay for a snapvault license on our new FAS3220 does that allow us to use an older filer as the actual storage space? I guess the other option is to mothball the FAS3140, but I hate to put down a good piece of equipment. Any thoughts or advice would be greatly appreciated. Thanks, Scott

SQL Server - NFS or CIFS which is better
by Joseph Bishop 21 Aug '13

Hello Toasters, We have a new NetApp and are going to migrate our SQL Servers onto it. For many reasons, I would like to avoid LUN provisioning and would prefer NFS or CIFS. Can I get feedback on which works better in practice? Best Regards, Joe
