All, There is an F760 filer head on ebay for about 4,000 right now. Here is the link: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=382392343

RE: Re-skinning the cat, might go with the F720 wo/CIFS ... -- WA S: Linux versus NetApp

Bryan, You have several options, and some cost more money than others. There are several software packages that are certified with NetApps and your library. Legato, Veritas, Workstation Solutions and SyncSort are some of the options. These all have different configurations that they support, (you can find the configuration info on the various web sites) depending on where you want to put the library. All of them support backing up the filer with the library attached locally, but if you want to attach the library to a Solaris server, Workstation Solutions will support that, and is also the least expensive of the solutions listed above. Check out their website at www.worksta.com However the cheapest solution is to attach the library to the back of the filer, and use the dump and restore utility. Several things to check out are, the library needs to be HVD not single-ended. It needs to be set in sequential or stacker mode, and you need to emulate an Exabyte 8900, since the filer will not support Mammoth until the next release of software. -----Original Message----- From: Bryan -TheBS- Smith [mailto:thebs@theseus.com] Sent: Thursday, July 20, 2000 2:33 PM To: toasters(a)mathworks.com Cc: thebs(a)theseus.com; b.j.smith(a)ieee.org Subject: Re-skinning the cat, might go with the F720 wo/CIFS ... -- WAS: Linux versus NetApp Re-skinning the cat, might go with the F720 wo/CIFS ... -- WAS: Linux versus NetApp All -- My boss and I took a step back and looked at the problem again. We remembered that 90% of our traffic is NFS. As such, paying an additional $8K for the CIFS support is probably not needed on the NetApp ($27K for the F720, 7x36GB, 1000Base-SX upgrade). I've had no problems with Samba on the Linux side and it's not our primary focus (we don't have a PDC BTW). I guess the only thing now is to figure out how to backup. I have an Exabyte EZ17 (7-bay autoloader, can and does emulate an EXB-210B) with a 20/40GB Mammoth[-1] drive. I don't (and never did) think much of the Mammoth, but the new 60/150GB Mammoth-2s are actually getting good reviews, only cost $3K and will allow me to re-use my autoloader. Again, anyone got any experiences with any backup software either on the NetApp or a NetApp agent to a backup server (like Solaris or Linux) that supports my autoloader? Dump might do though.

A simple workgroup (non-domain mode) case is easy to use - your PCs just authenticate using /etc/passwd or NIS, and you just need to change the Registry of your PCs to re-enable clear-text password. eT. --- Bruce Sterling Woodcock <sirbruce(a)ix.netcom.com> wrote: > From: "Bryan J.

Re: Linux-NFS list recommended I post here -- RE: NetApp versus Linux
by Eyal Traitel 21 Jul '00

Hi Bryan ! Please take into account these issues, which favor the appliance solution over the Linux box: 1. Proven stability of filesystem - NetApp's WAFL has real-life proven stability, which is consistent thru shutdown and powerdowns - even though ext3 is using journaling, WAFL's Consistency Points using the NVRAM should cover stability much better (and faster). 2. Crash recovery - filer's fsck (wack) is much much faster than other vendors' solutions - ~600GB/hr and more. 3. Ease of use - adding capacity is that easy - no extra config. Also - you're wasting time on choosing the right CPU arch. and motherboard bus chipsets - leave that to NetApp's engineering experts, and you can save time (and money, and get anyway better performance). 4. Extra NetApp-specific "bonus-features" - snapshot can lower your restore needs dramatically, and can help for some recovery cases. 5. Enterprise-level features which you can leverage in the future (which Linux doesn't have YET, not that I've seen, others - correct me if I'm wrong) - SnapMirror/SnapRestore, which complement the disaster-recovery issues. 6. Future growth - one filer can grow (now) to 1.4TB, which I don't think many Linux storage solution go that high, and NetApp will upgrade to 3TB and higher for one filer very soon. 7. Performance - CIFS performance should be much higher, NFS also much higher. 8. NFS/CIFS securuty - Linux can only share to PCs with Samba, which is fine, but only a user-level application (slower that Data ONTAP's kernel level implementation), and also the filesystem on Linux will still be Unix-based, and will not be able to maintain NT ACLs etc. I hope it sums it up somehow, Eyal. --- Bryan -TheBS- Smith <thebs(a)theseus.com> wrote: > Linux-NFS list recommended I post here -- RE: NetApp versus Linux > > All -- > > The Linux-NFS list recommended I post here.

some basic questions.
by Abu Ihsan 20 Jul '00

20 Jul '00

Hi, forgive me if these questions are too basic, but I need to clarify them first before start using our F760 Ontap 5.3.5R2. I'm in the learning process and I just could'nt find any faq on the net. true or false ? we cannot reduce size of a volume or reduce number of disk once allocated to a volume. we connot take a volume offline (from online state) without rebooting. we cannot create a volume in that it will become offline when created. we have to destroy entire volume to delete qtree. we cannot set maxfiles value for qtree. We have to set by volume. (I'm worrying about the news spool where we used to have a 512 bytes/inode on our UFS. How does everyone set their news spool, create a qtree for news spool or a separate volume ?) I don't understand below statement in System Administration Guide pg 72-73 : what does it mean by "The maximum RAID group size is 52 disks." when "The largest RAID group size you can create manually is 28 disks." thanks, --ihsanna __________________________________________________ Do You Yahoo!?

RE: NOW website down?

Hi Everyone, The planned downtime window for "routine upgrades/maintenance" to NOW is actually scheduled only during late hours (US PDT) on Saturdays. We picked Saturday nights based upon the small amount of web traffic that occurs during this period so that we can minimize the impacts to our customers. The outage that we experienced yesterday was due to internal networking issues and was not a "planned" outage. However, our standard "planned downtime" message below was displayed. We will look at making this message more representative of the issue at hand. Thanks for your feedback. If you have any questions/further input please feel free to send me an email directly.

Yes, I had the same question. Similar results can occur on the UNIX side when editing files with vi if the local partition that holds vi's tmp files (often /usr/tmp) is full.
