NAC on "Using the Linux® NFS Client with Network Appliance?"
by Quentin Fennessy 18 Sep '02

18 Sep '02

I don't recall seeing this mentioned on the toasters list. Netapp has a new (12 Aug 2002) white paper on Linux NFS client tuning, done by Chuck Lever. http://www.netapp.com/tech_library/3183.html I think you can get to this paper without NOW access. The paper is self-described as: This report provides advice for getting the best from your Linux NFS clients in an environment that includes Network Appliance filers. You'll learn what level of performance to expect from your Linux systems. You'll learn how to tune your Linux clients and diagnose performance and reliability problems. We'll recommend software levels and hardware combinations that are known to work well. Finally, you'll learn where to look for more information when faced with problems that are difficult to diagnose. Good stuff. two thumbs way up. This paper should perhaps be read while using an internal voice with a Scottish burr. -- Quentin Fennessy Quentin.Fennessy(a)amd.com Office: 512.602.3873 Cell: 512.694.7489

Re: NetApp Gripe.
by ScottUCE＠aol.com 18 Sep '02

NetApp operates no differently than other vendors -- hardware maintenance pricing ratchets up on aging systems as newer models begin to deliver in volume. However, third parties can usually provide hardware maintenance contracts for older systems that provide significant savings to the user in the range of 30-50%. As part of these contracts, spare parts and/or complete (unlicensed) "failover" filers/systems are often kept on-site; this paves the way for "mean-time-to-repair" and "availability" that are actually superior to what the manufacturers' field engineering organizations can deliver.

Hi Bruno, We ran Solaris 2.6 with ASE 12.0 for a while with the devices on our F820 and F880 but ran into some major performance issues. Mostly related to network throughput. Once we moved to 2.8 and SUN 2.0 Gigabit NICS, these problems disappeared. I am not a sybase expert, but I know we have a separate volume that we perform sybase dumps to. We ftp the dumps daily to a F820 at our Disaster Recovery site. This process works fine as long as we have bandwidth available on the WAN. We would have preferred to use Snapmirror, but that requires ASE 12.5 and a special quiesce procedure. You can find more on this at the NetApp NOW website, I think the article is a whitepaper on Sybase Disaster Recovery. If you have any more specific questions, let me know, I may be able have a chat to our Sybase Architect.

Volume sizes
by Haber, David J. 12 Sep '02

12 Sep '02

I just added two DS14 shelves to an F840. I have 24 of the disks available for a new volume(s). Would it be better to create 2 volumes of 12, 72G drives or 1 volume of 24, 72G drives. The filer is used as a cache for storing radiology images. No backups are required and there are no snapshots required either. I have two hot spares available.
