RE: Netapp support
by Glenn Walker 10 Jan '07

10 Jan '07

We use both NetApp and resellers - I cannot see a LOT of difference in their pricing. I'll tell you this, though: if you buy a LOT from them, they'll work with you on the price. Very easy to deal with, in my opinion.

Snapmirror transferrates??
by Thomas Bleek 09 Jan '07

09 Jan '07

Hello, I wonder what transferrate I could expect for snapmirror volumes (an/or qtrees) between 2 FAS270 directly connected with Gigabit Ethernet. We use one filer as NFS backing store for our Mailsystem (Communigate Pro) with mdir mailbox format, so we have many small files here. I see abnormal high lags with really moderate sizes of the transferred data. For instance we need about 20 to 40 minutes to transfer 100 to 600 MBytes! The filesystems a 50% filled 250 GByte Volume/qtree with 10.3 million files (with 7 mio free inodes). so the average filesize is about 12KByte. We use Ontap 7.0.4 here and will upgrade to 7.0.5 next week. But I don't really have much hope that this will change the problem. Could anybody give me some data about his/her transfer rates? I really can't believe, that this slow transfers are normal. An repeatedly snapmirror status command on the filer shows this: at first the transfer startet and transferred about 68 MByte in 80 seconds. after that it paused for 15 minutes (output constantly "transferring 68MB done"). from minute 16 to 26 it says "transferring inodes". in these 11 minutes it transferred 225.000 inodes. after that it transfers data again. in minute 28 it has transferred 550 MBytes. after that one minute pause and then the status is idle. Has netapp/snapmirror a big problem with small files? I don't want to switch to mailbox format because I like the advantages of mdir (single copy mailstore, easier backup?) Thanks for any hints, thomas

RE: Single file restore from a tape

I know this is possible using NDMP if the controlling software supports DAR (Legato, for example). 'restore' should have the same capabilities: http://now.netapp.com/NOW/knowledge/docs/ontap/rel705/html/ontap/cmdref/ man1/na_restore.1.html Glenn -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Brian Pascal Sent: Monday, January 08, 2007 6:09 AM To: toasters(a)mathworks.com Subject: Single file restore from a tape Hi, I'm using native ontap "dump" utility to backup full volumes of a filer. I find difficult in restoring a single data file from a backup taken to a tape to it's original location using "restore" command (i need to replace a single file in the active file system from the tape and not SFSR from snapshots). I take full volume backups (dump 0f rst0a /vol/volume_name), can i do a single file restore if i take full volume backups? Thanks.

RE: Snap restore monitoring

Snap Status might be what you're looking for. I know it shows creating status, and if I recall it will show volume rollback. Worst case scenario, they will be logged into the messages file. It's a very quick process (except for SFSR), so I'm unsure if you'll get much out of monitoring it actively.

RE: 3020 Cluster: which one is management interface

There are 4 interfaces that come with the system. You can use them in the way you had described in your first post, then use vlan tagging, to segment your management traffic from your production traffic. So your production still gets 4 interfaces, and your management interface is on a separate vlan from your production network. This is a different configuration then you were previously using, but that's the nature of this device. Alternately, you could purchase another nic from Netapp for management use. I'm sure you could negotiate a lower price then usual, since it's only going to be used as a management interface. -Blake On 1/3/07, Linux Admin <sysadmin.linux(a)gmail.com> wrote: > Blake, > Thanks again. > so is there a "default" management interface out the 4? > i was going to use 2 nicks to 1 switch (active) and 2 nicks to 2 switch > (passive) > 3 nics, odd number to work with vifs is very strange. > Now some people say they vif all 4 into one vif and use that for mgmt and > data. > how is it possible? > i am still confused > > > > On 1/3/07, Blake Golliher <thelastman(a)gmail.com> wrote: > > I meant using vlans to separate your management traffic from your > > production data traffic.

RE: Questions regarding snapshots
by Glenn Walker 04 Jan '07

04 Jan '07

There have been a few bugs in the past where multiple simultaneous snapshot creation attempts would step on one another (snapmirror and backups all create snapshots in order to function). I think most of these have been resolved in later ontap releases (beyond 7.0.2). To be safe, I wouldn't try to take an hourly snapshot and backup at the same time... As for performance, there's always the possibility of having issues due to snapmirror and backup running at the same time, but it would be based on disk I/O - if you're throttling snapmirrors you probably won't notice much. Regarding the snapshot creation process itself, you'd have to have a pretty heavily loaded filer to notice performance degradation due to snapshot creation\deletion (to the point of it being overloaded, generally). As with anything ONTAP, the bugs typically only come to the surface if the filer is at max performance capacity.
