I will be interested in seeing whether once you and us are using the same snapshot we get the same results.;-) It is a bit odd that reiser4 has both the lowest run time and the worst rating. We use middle of the road 32 bit CPUs (we'd like to use the latest ones but;-) ). For them our CPU consumption seems reasonable. -- Hans
Re: OT: NAS solution, Netapp vs EMC
Hi Where I work (ECE Dept at SIUE) We have a NetApp NAS setup with about .5 TB of storage. The speed is good, probably not great, but good. However I can say quite a bit about it's reliability. We've had it now for a little under three years and never lost any data, and we've had only one hour of forced downtime. There customer service is great. Once I showed up to work and we had a large shipment from NetApp. I opened it up, and it contained a drive shelf. We called netapp to see why they shipped us a shelf and there responce was "Your netapp shelf had a power supply falure, but the backup kicked in. Your F720 phoned home (via network) and told us about it, so we shipped you a new one". That night, we shut it down, moved the drives over to the new shelf, and turned it back on. It only took 15 minutes or so... We never even knew that the power supply failed, it just switched over and kept running without interruption. I don't have any expearance with EMC so I couldn't say anything about them. Later Cris P.S.

File system shootout v2.0...
Since the last shootout was so popular, I was able to get my hands on some better hardware to run even more tests on. As well the generated results format was improved slightly.

newbie dev requests
hello, from reading the code.html page on the website, is there any trivial bugs/features that anyone may suggest that i can do? i dont really know what i want to add, but i want to help. i have a strong background in backend programming, especially with databases. i hope this may be of help. i know a good amount about good programming and design, and just want to help. so if you got little stuff that is available let me know and i will start hacking away at it. i am new to filesystems, yet understand the concepts and theory i think, just not how it all works yet. so baby steps are nice :) anywho, hope to hear back with things i can do, not matter how trivial. thanks, chris
OT: NAS solution, Netapp vs EMC
Hi all, I am looking for a NAS server to work over NFS for 15-20 pieces of my linux servers. These servers will be involved in heavy reading and writing (about 30Mbps up and down each server) of experimental data collected from a network of probes. I am thinking of using a NAS solution (I have got a GigE LAN already) from either NetApp (F825) or EMC (Celerra) as centralized storaged for all the servers. I am concerned about the following: 1) Fast read and write performance for consistant stream of small files 2) Ability to store LARGE (> 10million per 200GB) amount of small files 3) Reliability...should not crash or go down when under consistent heavy load. Any comments about their performance?
