In my experience using a single big whatever is best unless you know precisely what your are going to be doing with it. A single big whatever is much more flexible. Having said that though I am not sure that a single gigabit connection is going to give you more throughput that an ether-channel, your really comparing 2 sorts of big. The same thing applies on the Unix side, I would probably be more inclined towards ether-channel on both. One thing that I have found is that having large differences in the speed of your server and client nearly always causes problems. /Michael

RE: Restoring DOT 4.x tapes on 5.X?
by Melvin, Grant 04 Jun '99

Hi Benjy, We work very hard in the File System Recovery group to maintain both backwards & forwards compatibility with our dump format. We also strive to be compatible with Solaris ufsrestore. If you have any restore issues then we'd like to hear about them. The best mechanism for this is to open a call record with NetApp support. Cheers, Grant -----Original Message----- From: Benjy Feen [mailto:benjy@feen.com] Sent: Thursday, June 03, 1999 10:11 AM To: toasters(a)mathworks.com Subject: Re: Restoring DOT 4.x tapes on 5.X?

I've just downloaded amanda in an effort to help me with a problem on an HP. First off, I'm impressed with the product. However, my particular problem is that HPUX wont recognize the norewind tape device for fbackup (it's local backup utility) altho tar likes it just fine. My question then is, how does amanda use the HP norewind device? Am I correct in presuming it just dumps tars/gtar to the device? How does it handle incrementals? If I did a find . -mtime -1 | tar ..... I'd pick up all the files created/modified within the last day but some of these files would have the same names (eg .dt/... files) altho they'd reside in different directories. Unless the path was hardcoded to each, they'd overwrite each other on the tape, right? And if they path is hardcoded, how could tey be restored to different directories? So is amanda just a client/server package layered onto gtar? Thanks ********************************* Jim Sanford IS Department Research Systems, Inc. *********************************

I strongly recommend contacting Netapp support about getting a software upgrade. Matt

Is or has anyone experienced any problems getting cifs to run on the netapps ? We have an F720 and are having performance problems with our win95 users. Just transfering files from a server drive to the F720 is very slow. The other problem is that several programs wont run if the files have multiple access, such as access. We changed the cifs.oplocks.enable to off .... Can anyone shed some light ? Mark Fowle

by Mike Ball 03 Jun '99

Will a cluster failover occur if a NIC card fails in one of the clustered filers? I have not been able to find a answer from level 1 tech support at Netapp or from the NOW site? Thank you, Mike Ball
