Re: Linux on netapp filers
by Blake Golliher 09 Apr '07

09 Apr '07

Installing linux on an awesome box like a 940 is pretty insane dude. As a server, you might find it underpowered. It's got 6g of memory, and 1.6 P4 Zeon processor (two I think). While you can get a modern Dell 1950 with a dual core Intel proc and 8g of ram for around 6k. Maybe you got a smokin' deal on the 940? Maybe you have no support, or any licenses on this box? I'm not sure you are going to get what you want out of this. A 940 is an awesome OnTap platform, for NFS block storage. As a platform for Linux or BSD, it might not be the best of choices.

number of disks in an aggregate ?
by John Foley 09 Apr '07

09 Apr '07

Hi all, I wanted to ask the collective wisdom out there about how many disks to put in an aggregate. I have an F825 with 2 DS14 shelves, currently set up as 1 aggregate (so 28 disks in the aggregate), double parity, and 2 spares. I will be adding another DS14 shelf, identical disks as the other 2 shelves. My preference is to just extend the existing aggregate to 42 disks, and set up another volume for the new data that will be going on there - but I believe NetApp says that 28 disks is the max for an aggregate. So, question is - anyone out there using more than 28 (like 42 !) disks in an aggregate ? Is it possible ? recommended ? I thought that the more disks the better in an aggregate for performance reasons, but I thought I'd see what you all say !

Weird NFS need
by Glenn Dekhayser 08 Apr '07

08 Apr '07

So I figured I'd give the group a shot at this. I've got a client that wants to have 2 linux-based ftp/http servers, one in the LAN and one in the DMZ, share some data. NFS would be perfect. However- The security group will not allow server in the DMZ to access the LAN-based Netapp through the firewall for its NFS resource. Also, I cannot put an interface from the Netapp into the DMZ. They WILL allow it if it's encrypted. I saw WebNFS, does Netapp support some sort of NFS over HTTPS? or SSH? Alternatively, the client said that what would be allowed is if the two servers could share the same LUN- FC only, no iSCSI. Has anyone out there tried that before, what needs to be done on the linux side to make that happen? Thanks Glenn (the other one)

ONTAP supports IPSEC. That should work, but it will increase the CPU load on the filer. I don't think it's an issue for HTTP/FTP setups, but it might cause problems with heavy PPS environments. What I don't understand is if the data their sending is basically unencrypted (HTTP and FTP?!??!) why does the NFS component need to be super secure from "teh hax0rz."?

Re: sizing files and folders on a filer
by John Foley 05 Apr '07

All - thanks for the replies. The java method was the most interesting, but I couldn't get it to work consistently - some directories it would work on, but others it would claim that the directory didn't exist. I tried a few things, but could never get it to be reliable, so I punted on that. Nice to know about it, though ! For the record, I will probably end up using a VB script from Windows to accomplish what I need to do, since in our environment the Windows client can get to everything I need to get to, and I there are several that are on Gb networking, so the sizing will be faster.

If not NetApp, then who ?
by Paul Letta 05 Apr '07

05 Apr '07

Hi Everyone, We are a long time NetApp shop here. We started with the 540 and have upgraded multiple times and are now at FAS940's. The time has come for us to upgrade again. We have been extremely happy with NetApp. The reliability, uptime, support, features, etc. have spoiled us for years. What I want to ask the community now is: has anyone else appeared on the stage that you are as happy with ? There are a lot of products that claim to have snapshots, NFS/CIFS, etc. But how reliable are they ? Has anyone that has been really happy with NetApps moved to any of the newer players and been as happy ? My motivation looking elsewhere is, of course, price. I admit, I have been slightly bitten by the cheap SATA file servers bug. Our current config is with all FC drives, but if you have enough disks, SATA seems to be close to the performance. Does anyone have any suggestions as to what NetApp's real competitors are ? Anyone have any stories to share with me about trying someone else (cheaper) ? Thanks, Paul Letta

sizing files and folders on a filer
by John Foley 04 Apr '07

04 Apr '07

I am looking for the "best" way to size certain folders and files on a NetApp filer. I get different numbers depending on whether I use Windows (2000) or Unix (Solaris 9). (I am "root" in both cases, and thus able to see all the files in a folder,etc). I am wondering if this is due to different block sizes used by those OSes - Windows uses 4K, and Solaris 512K, I think (!) So, my questions are : 1) what is WAFL's block size ? 2) what do you recommend for sizing folder and files that reside on the filer, but are not themselves qtrees (so the quota report won't work) ? 3) is there a "du" command on the filer itself that I"m missing ?
