Nexenta Systems you'd get some of the features. Still need some SSDs however but that would be a potent box :)
I'm interested to note that BackBlaze base their system on Debian running mdadm RAID - if it's good enough for an online backup company, it's good enough for a school's backup needs. I'm guessing most schools would be better running a Samba server on top of the RAID arrays, though.
What features do Oracle's 7000 series storage servers have over a plain file server that just lets users read and write files?
The key to the oracle is performance, analytics and overall product design. Really if you just want a pure fileserver its over-priced, its when you look at the whole package, when you get NFS, SMB, iSCSI, NDMP all in the box, plenty to read on here and once you've had one and used one anything else really isn't as good.
As John says the Oracle box is a whole package. It makes use of the same backend software stack as Nexenta (ZFS, Solaris etc) and adds good hardware and a nice gui analytics package. The advantage is the way it makes use of RAM, SSDs and HDs to give the fastest performance possible.
If you only wanted performance and weren't scared on the command line you could put together something similar using off-the-shelf hardware and Solaris/ZFS (or FreeBSD/ZFS). Alternatively you could possibly get something similar with Linux/BCache or Linux/Fastcache and one of the newer file systems (something like btrfs once its ready!) :)
I built my own 10tb home media server for under £1,000 here
MeediOS • View topic - Media server upgrade
It was surprisingly easy and cheap
I'm going to build a backup at work as well using the same principles.
I set up a NAS unit recently as a proof of concept, we only wanted it to snapshot our Xen Server so the specification is very low:
- Pentium 4 3.20Ghz
- 2Gb DDR2 RAM
- 2 x 1 Tb SATA2 HDD's in RAID 1
OS: FreeNAS 7.3 Sabanda running from USB flash drive.
It takes a snapshot no problem and has been used to backup the Staff areas using Symantec Backup Exec (Which we already use for main backups)
Total Cost: £0.00 (Had everything lying around - Bargain)
StorageReview has more details on this.
isn't much better (« this review shows you how to set it up on a Mac too).
Here are some benchmarks of my Drobo (connected via FW800 with a three HDDs). The first two are using the standard Microsoft FireWire driver while the third and fourth are with the driver from Unibrain.
NexentaStor Community Edition or ZFS Guru. ZFS is fantastic.
For some truly massive NASs you should take a look at the following thread on the HardOCP forums. Some people have 100TB+ at home!!! :eek:
Does anyone make use of the QNAP's medi library feature? How well does it work in a school context?
Following on with the QNAPs can anyone comment on the iSCSI reliability?
I keep getting warned that their implementation is somewhat wobbly, which is no good if I want to use it as a backup target. If not QNAP then are any of the other SMB-type NAS appliances any better?
I've got a DL180 G6 in my office at the moment that was the original plan for backup server (with Veeam installed locally) but HP decided it would be a good idea to run 4 fans at 10000rpm the moment you plug a RAID card in, no way that can stay in here :( Problem is haven't got any other places in the building away from the server room and something in me says having backups in there isn't a good idea (unless I can do some sort of realtime sync to... a QNAP?)
The BackBlaze Pod 2.0 is now out!
