RE: Real vs Raw disk space
by Todd Phillips 21 Dec '01

21 Dec '01

I just installed a new Filer with 72GB BCS drives and they formatted to 68GB. FYI: The only ones that format differently (ZCS vs BCS) are the 36GB disks. Need to be careful here. Ex: A 36GB BCS drive can not "hot Spare" for a 36GB ZCS drive as the BCS drive formats to a lower capacity. Tom's math below is accurate, + or - a tad. Nicely done :-).

For 73 GB drives, the "right-sized" size is indeed the same for both zone and block checksums. For 36 GB disks, there's a difference of 1GB between zone and block checksum right-sizings.

Since you can't use 14 disks and still have a spare, I'm doing this with one seven disk set and one six disk set. (68000 MB * 7) - 68000 MB (parity) = 408000 (68000 MB * 6) - 68000 MB (parity) = 340000 408000 MB + 340000 MB = 748000 MB 748000 MB * 0.9 = 673200 MB (lose 10% to WAFL) 673200 MB * (1 GB / 1024 MB) = 657.42 GB So... that would be 657.42 GB usable, assuming no snap reserve. However, I think if you're buying a DS14 you'll get block checksum disks, which might be right sized to a different size, in which case it would be a different answer. :) MD ----- Original Message ----- From: "Geoff Hardin" < <mailto:geoff.hardin@dalsemi.com> geoff.hardin(a)dalsemi.com> To: "toasters" < <mailto:toasters@mathworks.com> toasters(a)mathworks.com> Sent: Thursday, December 13, 2001 12:35 PM Subject: Real vs Raw disk space Toasters, We are looking at purchasing some new DS14 shelves with 72 GB disks. In order to properly forecast our disk space growth, I was wondering if anyone out there had taken a look at the difference between real and usable disk space realized with these new shelves and drives. Basically, our environment is as follows: DS14 Shelf with 14 72 GB disks (1 RAID group of 8 disks, 1 RAID group of 6 disks), attached to a filer running DOT 6.1R1P1. We will have 1 spare disk and no snap reserve. Geoff Hardin <mailto:geoff.hardin@dalsemi.com> geoff.hardin(a)dalsemi.com

RE: where do you usual sell a netapp ?
by Todd Phillips 20 Dec '01

20 Dec '01

Hi Ulf. With the introduction of the F87, and the F85s going for 10k or less, you almost have to give the 720s away. Plus, licenses are not transferable so, that's an additional expense for anyone buying a used filer. Make sure your asking price is in check with current market value. Also, NetApp is being extremely price aggressive these days. Todd Phillips Sr. Systems Engineer Integrated Archive Systems, Inc.

All the NetApp F720 I have seen lately on Ebay have 0 bids on them. I put some of them on watch list, but all of those ended also with 0 bids. -- Regards, Ulf. --------------------------------------------------------------------- Ulf Zimmermann, 1525 Pacific Ave., Alameda, CA-94501, #: 510-865-0204

Any horror stories upgrading to Ontap 6.1.1R2
by Maglinger, Paul 19 Dec '01

19 Dec '01

Considering upgrading our 740 to Ontap 6.1.1R2. Any horror stories or words of infinite praise or wisdom? In all honesty 6.0.1R3 has been running like a charm, our firmware is up to date, but our disk firmware is NA02 and the latest and greatest is NA06. Remember, you are unique... just like everyone else! Paul Maglinger A+, CA, CET, MCSE Systems Administrator Shoe Carnival Inc. (812)867-4674 pmaglinger(a)scvl.com

Ok, My fault for falling asleep, but I must have missed the f85 -> f87 transition. Looking at the f87 specs, I can't tell the difference from what I recall for the f85. Whassup with this new box? --Sam

What kind of security are you using, unix,ntfs or mixed? The latter one may cause more or less obscure problems. > is this happening because his id is in the nt domain admins group and > administrator is mapped to root in usermap.cfg? if so, what is a good way to > approach this? admins should always have two ids? Just the way NT works in a CIFS/NetApp environment. How does the netapp decide what Hat the admin is working under, as administrator or as self as a normal user? This is a problem I encounter often in a mixed environment. As long as the admin group users are not mixing environment ie just working from the NT world, things work usually OK. Ofcourse I have often a problem as I work in both worlds, and often have to change ownerships of my files to myself on my unix box. >>>>>>>>>>>>.rune -- Rune Bakken "I feel sorry for people who don't drink.

What cache value is what?
by l l 19 Dec '01

19 Dec '01

What does the "system board memory" value refer to in sysconfig? What does the NVRAM cache refer to? If I were to compute the "cache size" for a filer, which would I chose? I'm looking for the total size of the read and write cache for the filer.

hi, ontap 6.1.1r2 nfs and cifs, nt4 domain and nis. i have a user whose dirs and files keep getting their ownership changed to root and then he can't manipulate the files. he accesses his files from win nt 4 with an nfs client. is this happening because his id is in the nt domain admins group and administrator is mapped to root in usermap.cfg? if so, what is a good way to approach this? admins should always have two ids? thanks. -- regards +++++++++++++++++++++++++++++++++++++++++++++++++ + Neil Lehrer + + United States International Broadcasting Bureau + System Development Division + + voice 202 619-2524 + fax 202 619-3576 + nlehrer(a)ibb.gov + + " is this crisis an opportunity or just + another grab the fire extinguisher moment?" + +++++++++++++++++++++++++++++++++++++++++++++++++
