Low SMB throughput
by Alfred Lerch 09 Oct '00

09 Oct '00

Friends, we are running a F740 in a heterogenous NFS/SMB environment. While we are completely happy on NFS performance SMB performance is not what we would like it to be. But it is only on some Win95 and NT 4.0 where then throughput is low, other Win95 and NT 4.0 systems with the same configuration are fine (as far as you are able to state that two Windows installations are the same). Looking to our 3Com switches shows us that it is not an issue on the ethernet level. I personally guess that it is a protocol issue between the NetApp and Microsoft implementation of CIFS/SMB/NetBIOS over TCP/IP but I'm unable to verify this. Any ideas where we might start looking ?

RE: mixing 18GB and 36GB drives
by Whitman, Matthew 09 Oct '00

09 Oct '00

If there is a 18GB drive available (or for that matter 2/4/9/etc.) The filer will take the appropriate drive size spare to rebuild that drive. In your example: > > I've got a filer with a shelf of 36's (one RG/volume) and two > >shelves of 18's (one RG/volume); each RG has a hot spare. The following would happen: 1) 18GB drive fails; the filer grabs the 18GB spare 2) 36GB drive fails; the filer grabs the 36GB spare 3) 18GB drive fails and rebuilds to the 18GB spare, you then lose another drive, the filer will grab the only remaining spare, the 36GB drive.

My thanks. I've received several replies. The summary is: Just make the path be something like /vol/myvolume which I was already doing. One person asked about existence of /etc on each volume. Yup. It's there, and writable by root (who runs the backup). The Budtool support folk have had this question pending for a while; I've just stirred them up again this morning, I hope.- Apparently, I'm just unlucky.

The webpage at NOW <http://now.netapp.com/NOW/products/eoa/> says a customer letter was sent out about this on 6/29/99, but no one here seems to have gotten a copy.

Snapshot access usage

Does anyone know of a way to tell if files in a snapshot have been used for recovery and how often? My guess is that this could be done by capturing file access statistics on the filer. We are trying to keep snapshots online as long as they are needed, but also trying to not waste space by retaining snapshots too long. If anyone from Netapp is listening and there is not a way to capture these statistics, it would be a good thing to add - Hint, Hint!

We have a pair of 630s that we've been trying to cluster for about 15 months. Downtime is that hard to schedule. We are upgrading to a pair of 760s, already clustered, hopefully next weekend. Because the upgrade from 5.X to 6.0 is lengthy (~ 1 hour i have heard) we are considering upgrading the pair to 6.0 before the move, otherwise it might be many months before I can schedule a downtime of even that hour. versions that are "anything.0" are always treated by me as ... suspect ... so I am looking for comments/experience on the stability of 6.0 - while i know that we can back out, i'm going to be lynched if the new filers turn out to be unstable. thanks. -- email: lance_bailey(a)pmc-sierra.com box: Lance R.

RE: Optimal volume size
by Clarke, John L. (CIS) 04 Oct '00

04 Oct '00

We have a similar situation on our F740. We want to keep the volume size small because: a) Restores can take forever as the data size gets bigger. b) 10-14 disks is a good compromise on reliability. Having 2 out of 14 disks go bad at one time is much rarer than 2 out of 51 disks. c) If you upgrade disks/shelves in the future, you will likely do it a volume at a time. We did this with a volume with 180GB and the volcopy took 6-7 hours to complete. It is NOT very fast. With 400GB+ in a volume, that should be 2-2.5x longer. John -----Original Message----- From: Moshe Linzer [mailto:Moshel.Linzer@nsc.com] Sent: Monday, September 18, 2000 4:31 PM To: toasters(a)mathworks.com Subject: Optimal volume size We are moving from a 630 with a single 350GB volume (51x9GB SCSI) to a new 760 with 14 36GB disks. Our Netapp support recommends creating a 14-disk raid group, with a single raid group per volume (giving us a maximum volume size of around 400GB). I understand why 14 disks is a good number for a raid group (balance chances of disk failure vs efficient use of disks), but what is the reasoning behind keeping volume size down to around 400GB? Is it just dependant on restore time from tape? In which case, as faster tapes become available (LTO?), this number should increase. Does it also lessen chances of file system corruption on the volume, or is it just a warm fuzzy feeling that all your eggs (so to speak) are not sitting in one 1.2 terabyte volume? If my max volume size will remain the single raid group, I would like to divide my data into 2 smaller volumes from the start, so I don't start off with a maxed-out volume. This means using a time-consuming ndmpcopy or rsync process to move the data, instead of the faster volcopy or snapmirror. Thanks for your insights. Moshe

RE: Netapp vs Compaq TaskSmart
by Joe Luchtenberg 03 Oct '00

03 Oct '00

Regarding the items you indicated are important to you: Multiprotocol NFS/CIFS: both Compaq and NetApp serve data to both NFS and CIFS clients Capacity: Compaq currently scales to 1TB raw capacity (that is approx. 800GB usable, accounting for parity disks, hot spare and minimal SnapShot overhead); that is less than 1/4 of current NetApp single head unit capacity; however, Compaq does use 1" 18GB disks (granted they are SCSI), so with 14 per shelf you do get some density gains with less overhead in the same physical space (i.e. 18GB parity and hot spare overhead vs. 36GB each for NetApp) Uptime: Compaq's N2400 is a first-generation product with a limited track record, therefore difficult to predict; NetApp has maintained documented 99.99x% availability Reboot time: Compaq claims a Rapid Reboot functionality; since they basically run a tuned Windows 2000 OS (as opposed to NetApp's built-from-the-ground-up single purpose microkernal OS), I'm curious how the get around fsck and what, if any, penalty is incurred SnapShot mirror: this is really two issues 1. Snapshots: Compaq integrates their SANworks Virtual Replicator (SWVR) software in the N2400; this provides a different implementation of snapshots from NetApp; basically, once a snapshot has been taken of a volume, the next time any data block in that volume is changed the SWVR delays the write until a copy is made of the original data (subsequent changes continue with no delay); obviously, you take a write performance hit 2. Mirroring: I'm not entirely sure, but I'm not aware of an asynchronous remote mirroring product from Compaq SANworks; their Data Replication Manager supports mirroring across a long-wave FC connection (up to 100 km if implemented correctly), but this is very different from the capability to replicate across the WAN, while minimizing impact on bandwidth as with NetApp's SnapMirror Other items to consider: - Compaq's implementation uses RAID 5; this is an issue when it comes to volume expansion; the SWVR software allows online expansion by creating new RAID groups and concatenating them to existing storage "pools," in which case you use the additional disk space only once you've filled the original volume (no gain in spindle density); to expand an existing RAID set, you have to reformat, rebuild and restore from tape; RAID 4 is much more administrator-friendly. - If you have a Compaq SAN, then future upgrades to the Compaq NAS line will allow you to connect to the SAN (for centralized backup without clogging up the production network, for example) FWIW, pricing is roughly comparable b/w Compaq's N2400 and an F740 (Compaq may be a touch cheaper). If you add in things like SnapMirror or SnapManager for Exchange, then NetApp gets a lot more expensive, but then you can't get equivalent functionality of those products in a Compaq solution. HTH.
