Pushing the limits
by Jeff Stampes 19 May '00

19 May '00

So we use a F760 for compiling our software....it's a demanding environment, and up until now, NetApp systems have been adequate for us As I've been refining our build process though, I've continuing optimizing it to the point the 760 may become our bottleneck. It seems to be running at about 50-60% of CPU most of the time, with peaks like: CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 98% 4243 6 0 6365 7367 10648 15352 0 0 3 74% 4515 1 0 11902 8348 3592 44 0 0 3 100% 4644 2 0 9472 11021 7763 8088 0 0 3 88% 4307 0 0 9223 9463 7023 10938 0 0 3 100% 5606 0 0 8870 9185 6048 11368 0 0 3 75% 4884 4 0 8622 13913 4032 2432 0 0 3 100% 5717 6 0 6777 10372 6700 11488 0 0 3 I don't knwo when I need to worry....so I have two questions: What stats will cue me into a problem related to overload? What are the limits of CPU/Net/Disk use I should stay under? Provided I find a way to drive an F760 into the ground, any suggestions for a next step? -- Jeff Stampes -- Xilinx, Inc. -- Boulder, CO -- jeff.stampes(a)xilinx.com

The "root"-option is more secure, but this setting has one big drawback: You cannot use netgroup names with the -root option and you can specify only 256 host names! If you have only few machines, the -root option is the better choice. In large server farms with more than 256 machines that are running CDE+dtlogin (XDMCP) the -root option will not work.

Yikes! Both are very insecure choices for a solution!!! The correct answer is to simply export the home directories with root access for those machines that are running CDE that they are logging in through. Bruce

SQL Server 7 with data files on toaster?
by Colm Buckley 19 May '00

19 May '00

Hi - Another request for success or horror stories; does anyone on the list have experience with running MS SQL Server 7 using a toaster to store the data (as described in http://www.netapp.com/tech_library/3042.html and http://www.netapp.com/tech_library/3044.html)? One possibility being looked at here is to run a database from something like a Dell PowerEdge 8450 with the data files on an F720 or F740. I'm aware of the advantages the toaster will bring in relation to backup, snapshots etc, but I'm interested in how the performance of such a setup would compare to, say, attaching a big LVD or Fibre RAID5 directly to the server. Any comments?

Hello *, I think it´s a problem with the permissions on your home directory. The dtlogin process (CDE) reads and writes configuration files in the homedirectory (~/.dtlogin/..). The owner of the process is root --> But root has not permissions on mounted directories! Try out to export your homedirecties with the "anon=0"-flag in /etc/exports -or- you should open your homedirectories for everybody (chmod 777 homedir) :-(( to avoid this problem.

Hi! What kind of Security Style are you using? We've seen this with Solaris 8 using NTFS Security Style.

Has anybody had any thoughts or done any testing with the following configuration? Basically connecting a Netapp into a SAN for backups not storage. One Netapp F760 One extra Fibre Card in the Netapp One Firbre Switch (Brocade or Ancor) One Tape Library connected into the Fibre Switch. Veritas Netbackup and NDMP Solaris or NT Netbackup Master and several Media servers Connect the Netapp into the swtich with the extra fibre connection. Zone the switch so the Netapp and two tape drives are tied together. Backup driectly to the tape drives by using NDMP. My questions to Netapp are: 1) Is this possible? 2) How would the Netapp log into the switch? As a Loop or Fabric? 3) What is the solution for backing up a Netapp directly to Fibre tape drives? 4) What is supported? I am going to test what I thank will work but any thoughts or ideas would be helpful. Jason Middlebrooks Systems Engineer Datalink Corp. 888-933-9327 x2970
