    NAS Devices - What shall I get??

    Hi Folks,

    Our server is slowly running out of storage space and I'm thinking of putting in place some kind of NAS storage device. Can anybody recommend anything in particular or something that will work well?

    We are running a Windows Server 2003 Network with Active Directory; I have about 1000 users on the system. I was looking at getting something like a 1.5 to 2 TB drive

    I've been looking at the Buffalo TeraStation Pro II and also RM’s version “NASBox” which uses Windows Storage System platform. http://www.rm.com/Secondary/Products...?cref=PD477914 (Don't go buy the price on the website, been quoted better)

    I’m looking for something that will be simple to setup, and that I can easily move the data from our current servers hard drives and create new folders and share on the NAS device,, although I’m guessing that I’ll probably have to re-create all the shares/permissions etc etc

    Is there anyway in setting these devices so that they “think” they are just a new hard drive in the server, and extend the current partition size so the server thinks that the storage drive is now a 2TB disk instead of a 250GB disk?

    Cheers,

    Matt

    You could always do it 'properly' and add a SAN.... adding the storage as you need it. The disks then appear local to your servers.

    Sounds good... any pointers or links that anyone could suggest/recommend? ... also if it turns out that cost is a problem, any tips on the NAS!

    Cheers,

    Matt

    Watch out on lower end NAS boxes for poor Active Directory integration. For example, both Buffalo and Iomega claim some of their NAS boxes will integrate with AD, but it only works if your AD domain is in Mixed mode. Now some ADs may be still in Mixed mode, but if they have been upgraded to Native mode (2000 or 2003) then there is no going back.

    Whatever you consider, check the user forums on the supplier websites for disgruntled customers.

    You can also home brew a NAS/SAN with OpenFiler.

    There seems to be a major lack of specifications on the RM units on their site, such as what type of hard disks are used and what redundancy is provided (power, ethernet etc...).

    I have both a Windows 2003 Storage Server NAS box (Fujitsu Siemens FibreCat 2TB) and a Adaptec Snap Server 520 (2TB) and find the SnapServer to be the least work. It took 10 minutes or so to set it up as an iSCSI drive on a normal server and voila, it needs no further setup. Whereas the Windows one seems much slower.

    Also, the RM unit is 2U in size, which now may seem like no problem but in a few years time racks will start filling up and a 1U unit would seem like a much better idea.

    Re: NAS Devices - What shall I get??

    I am sorry if i am a bit out of order here but I have just set up a nas box and it cost me £0. I had about 6 hard drives lying around manage to get hold of a controler card ok it is ide and has sofware raid but i installed openfiler and i now have about 160gb with raid and it cost noting and was so easy to set up everyone has shares on it and it is really good. Ok its not a nas box and you do need to install the software but it is really simple. and i beleve you can go as big or as small as you like have worked out for £200 i could have 1tb with raid and hot swap sataII drives

    What is the reliability of that though? How much trouble will it cause when it goes down? I'm all for reusing equipment (it should be done as much as possible) but on something as important as the central servers you need the stability and fallback of something substantial. If it breaks, you will receive questions as to why there wasn't a repair warranty on it for next day.

    Doing stuff like that is kinda against the idea that school's are supposed to be becoming more business-like when it comes to their ICT.

    I used to get 3TB out of a 1u rack. 4 hot-swap SATA-II drives and a redundant PSU to boot

    Generally used open-e NAS but sometimes Windows Storage Server.

    Obviously this was never as cheap as a 'commercial' product but very reliable/scaleable.

    Aye very good, now give us business money

    Nothing wrong with doing like he has, how exactly do you think he replaces ANY part? His way he can replace a faulty part in 5mins not next business day.

    RAID 5 setup with spare PSU, RAM, CPU (all quite normal things to have laying about the office) and then if the mobo fails just go buy one frm your local shop - far far better than phoning up some forgein idiot in india who doesnt know what your talking about and then sends an engineer with the wrong part.

    We've got a NAS and i wouldnt even think about buying another one when the free ones are better (unless you have £1000s to spend)

    Re: NAS Devices - What shall I get??

    relibilty of the openfiler is supurb i have been testing it out over the last 4 weeks or so and hammering it to death and so far it has taken more stick than i can give it. also as it is a linux based it is free and something i tried the other day even with the dc switched off i can access the openfiler system. Origanaly i tested it on an old p2 256 meg of ram and 4 ide hard drives mounting up to 14gb of storage and it still worked fine. they have also relised a 64 bit ver but not tested it myself yet. (by the way it way ty goeff) as it was a post about 4 weeks ago i asked the same thing.

    Even server failure isn't an issue. You still need some form of backup for archival purposes or restoring from accidental/malicious deletions.

    How can you cover terrabytes of data without spending shed loads more on a backup system.

    Yep. Its almost impossible now as a school to afford to back up that amount of data, itll be great when all the multimedia comes in properly, imagine it for uncompressed video for 1000+ kids . External HDs are starting to get used around here atm but they aint exactly the best backup device.

    Freenas:

    In the middle of moving our media server over to 1 terabyte box I have built with a few 500 gig driving using JBOD....
    I have not tried using the AD support in it but you can always give it a go first as its open source....
