Deduplication volume size limits.
by Ray Van Dolson 30 Jul '10

30 Jul '10

The most recent documentation I have states that there is a 1TB volume size limit for SIS enabled FlexVol's on FAS2050 hardware. Is this still the case as of Data ONTAP 7.3.3? I hear rumors from time to time of the limit being increased to 2TB or beyond, though I understand memory is the limiting factor. I'll keep searching around NOW for newer documentation than I have but figured someone here would know off the top of their heads. :) Thanks, Ray

Deduplication and space usage - best practices
by Ray Van Dolson 28 Jul '10

28 Jul '10

We use deduplication on our N3600 (FAS2050C) with ESX (vSphere these days) via NFS. I'm curious how those of you out there with a similar setup manage your disk space and identify "critical" threshholds. We also do thin provisioning so we're thinking about a worst-case scenario where we have to restore from backups and end up with thick provisioned and non deduped VMDK files. We don't want to be too conservative though -- may as well not be using dedupe at all... :) Interested in how others on the list deal with this. Thanks, Ray

10gb Network Bandwidth concern
by ifstat 21 Jul '10

21 Jul '10

We have installed dual port 10Gbe (x1008a-r6) in our FAS3170A, configured them as a vif using lacp, with load balancing as mac. What we are noticing is that we are only get 1.4Gbits bandwidth per port. Even though we should realy be achiving at least 20Gbits. The filers connect to a 6509 CISCO switch, with each interface connecting to a different module for redundancy. The two interfaces from the filer define a port channel on the switch so that they reflect the vif on each filer. The tool we use to check on the throughput is called Solarwinds and Orion. This tool shows that: a. For netapp1, each interface is shown to work at 1.4101Gbits. The vif is shown to work at 2.8201Gbits. b. For netapp2, each interface is shown to work at 10Gbits. The vif is shown to work at 20Gbits, but we don't get more that 2.8201 Gbits Is this normal or what are we misising? We have a case open (2001542643) is anyone for NetApp has access.

Slot labeling for a 3070?
by Page, Jeremy 20 Jul '10

20 Jul '10

I'm getting a set of PAM II cards for my 3070 and have started doing some of the installation research. The system configuration guide recommends they be installed in specific slots but I can't tell what they mean. Is there a doc that has the slots diagrammed in it?

Boot from SAN
by David McWilliams 12 Jul '10

12 Jul '10

Does anyone know how to configure boot from SAN when we multiple paths available to us? Obviously we will not have true mutlipathing available to us at the BIOS level. Is configuration of the boot order an acceptable solution or does anyone else know of any cleverness out there.

Physical displacement of disk shelves -- hot ?
by Simon Vallet 02 Jul '10

02 Jul '10

Hi, I'm currently trying to physically move two aggregates from one filer (3020) to another one (2050), and I'd like to do that without service interruption. AFAICT, I'm first supposed to boot one head under maintenance mode to take the aggregate offline, but when I do that (on the taked-over head), I get a quite scary message relative to possible data corruption. So the question is : is it at all possible to take an aggregate (containing FlexVols) offline and move disk shelves in takeover mode ? Cheers, Simon

upgrading fas3050c to fas3170a
by ifstat 01 Jul '10

01 Jul '10

I'm upgrading FAS3050C to FAS3170A I know of the following tasks: 1- same version ONTAP on old and new controllers 2- disk reassign ownership form old_sysid to new_sysid 3- mailbox destroy local 4- mailbox destroy partner 5- lun serial numbers to be change to what they were before the upgrade 6- software install ONTAP for FAS3170 after upgrade 7- license add 8- edit /etc/rc file for networking ports to correspond to new ports e0c to e4a example. Is there something that i'm missing or any other gotcha's that i can avoid. -- View this message in context: http://old.nabble.com/upgrading-fas3050c-to-fas3170a-tp29043587p29043587.ht… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

SL SMB misery
by Carl Howell 25 Jun '10

Like many of you, we have been having lots of weird issues with Snow Leopard and SMB. We've upgraded to 7.3.3, but that hasn't helped. A lot of the symptoms we are experiencing are mentioned here: http://discussions.apple.com/message.jspa?messageID=11041594 For those of you that are having these problems, what are you doing to try to solve them? Thanks, Carl Howell Systems Engineer Information Technology Services
