QTree Size limits
by Jack Lyons 12 May '04

12 May '04

I have a 1.31 TB volume that is 90% full. There are two solutions I have available to me. One is to try to reduce the amount of space on the volume (but meeting resistance by users). The other is to add space. I am trying to get approval for another TB of disk space, but I don't think the best solution is to add it to the existing QTree. My backup window for this volume is 14 -15 hours currently and would only get bigger if I add space and that is not acceptable. I know I can another qtree / cifs share but I was hoping I could do it in such a way that I would still have another Qtree but make it available to the user via a single CIFS Share. Currently /vol/vol1/creative is the qtree and I have a cifs share (called creative) pointing to /vol/vol1/creative, so the users connect to \\server\creative <file:///\\server\creative> (or for the Macs) smb://server/creative I was hoping I could add another volume, probably /vol/vol2 with a qtree called /vol/vol2/active clients and some how make it appear to the user as a subdirectory under \\server\creative <file:///\\server\creative> This is probably confusing, so please ask any questions.

: Can you tell me whether or not a TB = 1000 GB or 1024 GB It looks like you're referring to DataFabric Manager, which uniformly uses 1024 as the multiplier for K, M, G, T, P, and E calculations. : In my volume properties screen: : : Used Capacity: 1.18 TB : % Used: 90% : Total Capacity: 1.31 TB : : But in my Manage Volumes screen it shows I have 127 GB available. : 1.31 - 1.18 = .13 TB = 133.12 GB if 1 TB = 1024 GB : 1.31 - 1.18 = .13 TB = 130 GB if 1 TB = 1000 GB : : 127 GB = .127 TB if TB = 1000 GB : 127 GB = .130 TB if TB = 1024 GB 127 GB / 1024 GB/TB = 0.124 TB. 1.18 TB + 0.12 TB = 1.30 TB, which is just about 1.31 TB. All of the values involve roundoff, so the sums will rarely match exactly. - Brian

Implementing VIFs
by Ben Rockwood 07 May '04

07 May '04

Hello Toasters. I want to migrate all my Filers to using VIFs for switch redundancy. But in my testing so far, I can't see any way to get around taking an outage, assuming you want to retain the same IP, since you aren't allowed to create a VIF with the same IP of a live interface. Does anyone know a way around this? It still seems best to take an outage to reboot the filers and verify that everything is going to work properly in case of a panic, but I'd still like to avoid it. Thanx. benr.

Mail queues and rocket drives
by Maren S. Leizaola 07 May '04

07 May '04

Hi, I've been thinking about moving our outbound mail relay queue and deploying a NetApp. However I came across solid state disks. I found that in terms of SCSI based solid state drives Curtis makes the best and most affordable stuff in the 1G-8GB size. It has SCA interfaces and dimmesions of a SCSI disk that will fit into a hot swap bay. These start at around US$2000 and seem to max out at 10,000 transactions per second. Given that our mail queue back log does not grow above 100MB I am thinking of getting Cenetek's Rocket Drive with 1GB, this is a PCI board that has its own external power and hooks to your UPS. A magazine benchmarked them to 30,000 transactions per second at US$1000 it seems like a bargain to me. Centaket rate them at 100K transactions per second. In its price range feature performance it seems to have a very clearly defined niche. It also beats ram drives as it does not require the machines CPU to do the IO. Anyway I just want to know if any of you guys are using these to boost your servers and have any opinions or advice.
