Jumbo frame
by Derek Lai 22 Apr '04

22 Apr '04

Hi I just took over the administration of a F940C cluster. They and the servers are on a dedicated network running Gigabit Ethernet through a Cisco 6509 switch. I noticed that jumbo frame was not turned on. I had asked the previous administrator why and he said that they had tested the systems initially with Jumbo frame and did not notice any appreciable difference in performance. The main applications we are running are 3 databases - Oracle on HP-UX, Oracle on NT and SQLServer 2000 on NT. Anyone has good performance numbers using Jumbo frame vs. not using Jumbo frame? Jumbo frame is one of the highly recommended things by NetApp and I'd like to implement it but it sure would be nice to have some idea so I can set the right expectations. Thanks. Derek

Block size and ops/sec
by Edward Hibbert (eh＠dataconnection.com) 19 Apr '04

19 Apr '04

Suppose you have 20K of data to write. You could write that as a 20K chunk, or 10 chunks of 2K. I'd have thought that writing a chunk of 20K would be less expensive for the filer. Does anyone have any actual info about the effect that tuning the block size can have on the number of ops/second you can expect from a given filer? Regards, Edward Hibbert.

Private Gig Switch for Oracle mounts
by Robert Borowicz 19 Apr '04

19 Apr '04

My boss bought two Cisco 3650 Gig switches of which he will expect me to interconnect our Filer ( FAS 940 ), 3 SunFire 880's, 3 Sun E450's and 6 Gateway 975 Twin Xeon SuSe boxes to. The 880's and the SuSe boxes will all run Oracle over the switch back to separate Volumes on the Filer. The filer's Gig card is a "X1025C-D" Gbit, NIC Fiber card. I've asked that we purchase another Gbit card on the Filer so that I can do a failover VIF. I'm concerned about utilization on the Gbit interface on the Filer. Anybody have a similar environment and been there already? I'd like to trade notes if so. Thanks -Rob

RE: Private Gig Switch for Oracle mounts

Rob, I have a customer that is running Oracle on 12 v480's connected to a NearStore R100 and another 4 v480's to a FAS940. I have a single Gig Card from each server connected to two Cisco 3750 switches with a dual connection on the back-plane. The NearStore has 2 dual-port gig cards that have been set in a four port multi-vif and the Filer has three quad-port gig cards set into four multi-vif's with a second level multi-vif combining the two of them. It is important to remember that when setting up a vif you'll need to configure etherchannelling on the switches to support it. Cisco currently only support 16 ports in an etherchannel (just like NetApp) but only eight are active and the remaining are backup. Cisco will handle all of the load balancing. Bench marks at the customer revealed at 35% increase in performance with the NearStore and 50% increase from the Filer. Before NetApp they had all A1000 direct SCSI attached to each host. This is more than what yo uare looking at but I hop ethat it shows what the Appliances are capable of handling. Remember also that 99% of Oracle Corp, runs on NetApp Storage.

I have a couple FC8 shelfs that are no longer being used on Filers. Can I reuse them on non-NetApp hardware? Steve Evans SDSU Foundation

Re: NetApp DR Tape Solutions
by Andrew Siegel 16 Apr '04

We have a clustered F880 with about 8.5TB of usable data on it, split among a dozen volumes. FWIW, we back this up onto three LTO2 drives in about 60 hours (i.e. we start it at 7pm Friday and it runs until Monday morning). This occupies about 24 tapes. We originally wanted the 9940B, but it was too expensive, and I have to say that I am very happy with the LTO2. I have not had a single media failure among the nearly 500 tapes that we've used. They are very fast and very reliable. -- Andrew Siegel Head of Systems Blue Sky Studios, Inc. 44 South Broadway, 17th floor White Plains, NY 10601 914-259-6336 direct 914-259-6500 main 914-259-6499 fax abs(a)blueskystudios.com
