RE: Linux, Samba and CIFS
by Benn, Paul 29 Jul '99

29 Jul '99

What are you using to mount the share? What version of Data ONTAP are you using? Regards, Paul -----Original Message----- We're trying to get a Linux box, using Samba, to mount an NT share to our filers. We have been, quite successfully, accessing the filers from the NT domain they are in using normal UNC share names. We have also, successfully, mounted NT shares from the Linux box using Samba. The failure seems to be in some area of authentication on the part of the filers that is somehow unique to them as other NT systems are quite happy talking to the Linux/Samba mount.

CIFS Remote Backup Options
by Mohler, Anissa 29 Jul '99

29 Jul '99

I am working on design of a backup system for our F740 filer (100G usable) in a CIFS environment. At this time we have no plans on directly attaching a tape backup device to the filer. Our current enterprise backup solution is ARCserve 6.5 (on NT). I have the White Paper on NT Backups and am wondering what is actually in use in the field. Are there any gotcha's I need to watch out for? Any best practices out there? Thanks! Anissa Mohler amohler(a)mail.bokf.com BOKf Network Services Group

Ok, Ive double checked /etc/netmasks (already was there) /etc/notrouter, /etc/defaultrouter (already was there) changed mac addresses on qfe0-qfe3 so the switch doesnt look at all five interfaces on the machine as one MAC, dbl checked VLAN configs on the Cat 5505 ports.. Still, the Sun wants BADLY to route 10.16.118.0 traffic across the public hme0 interface, instead of the up/configured/plugged-in 10.16.118.23 interface.

fcal tape drives?
by alexei＠mindspring.net 28 Jul '99

Has anyone from NetApp started playing with the FCAL tape libraries, like the ones from ADIC or Spectralogic? Support for the Spectralogic Bullfrog would be very cool. Alex

RE: Non-NDMP backup solutions?

Hi, After reading this thread, it seems that ndmp is the way to go and most of the incompatibilities between various vendors have been taken care off. I am quoting some from parts from this thread below and at the end I am putting my most recent experience with ndmp which was today itself. "Shaun Erickson" wrote: > Because of the frequent upgrades, (which continue to happen, but for > other reasons) we frequently ran into problems because of > incompatibilities between NetApp's implementation of NDMP and BudTool's. > Then, when we'd try to get support, we were always told that the version > of Ontap we were running wasn't certified with BudTool, so it was always > a major pain to get support.

For backups I am using budtool with ndmp for my toaster. I upgraded my budtool installation from 4.5 to 4.6 with patches 1,3,4,5,10,11,14,17. The upgrade broke the file history creation/merge part only for my toaster which is using ndmp. For other file systems (Sun/Irix) file history is working fine. I called Intelliguard (now Legato) for support. First thing the support person does is to point me to their certification matrix ( http://www.iguard.com/products/certmatrix1.html ) which does not have any mention of ONTAP 5.2.2 and hence it is not supported. The person tells me that I am out of luck unless I run a supported version. I pointed the person to the piece of code which was broken, and responsible for the problem, the support person agreed to look at that but at the same told me that no change to budtool code can be made for an *Unsupported* ONTAP release which coincidentally is the **Recommended release** from netapp. I guess, that speaks a lot about **COORDINATION**. The choice I have is to either upgrade to an early access relase (5.3.1), which I won't do on a production toaster, or move away from ndmp. rajeev

At SAS, we have seen NFSops/sec in the 25000-30000 range:-) So it definitely depends on what you are doing with the filer Dawn -----Original Message----- From: alexei(a)mindspring.net [mailto:alexei@mindspring.net] Sent: Tuesday, July 27, 1999 12:40 PM To: dmidgett(a)about.com Cc: toasters(a)mathworks.com Subject: Re: ops/second "David Midgett" <dmidgett(a)about.com> writes: > How many ops/second can the F760 handle? It depends on the mix of read/write ops you are doing, as well as what else the filer is busy doing. The f760 is rated (per SPEC, http://www.spec.org/osg/sfs97/results/) is abround 7500 NFSops with the read/write mix they put on it. In one service (with almost equal reads and writes), we see somewhere around 75% cpu with 4k nfsops and 2M/sec in and 2M/sec out, on average. The peaks are much higher, and disk reads/writes are quite high. The cache age is low (3 min). This is on a loaded f760 with 1GB of cache, 3 raid groups of 14 drives (9GB) each. On the other hand, in a mainly read environment I have seen filers push the 9k+ nfsops and pushing 10M/sec with highg cache age, while the cpu is still not higher than 80%. It all depends on your mix and your configuration. Alexei
