this is something i am starting to do as getting hold of older disks is a pain
Seems that some companies quoting so far feel that either the spec I'm listing is too low for the users (Max 70 machines - approx 40 concurrent with the odd laptop now and then) and/or my budget is too low.
I'm looking at a budget of £1400 ex vat.
With the weak link being the SATA drives, would you go SAS?
i think the companies who are saying the spec is "too" low are just trying to get you to spend more money...
you might find you need to trim back the spec a little but still buy a system which allows expansion later (say in another year or so) that way you can add extras as more cash becomes available.
Or the other option is to say "this" is the cost of achieving your requirements.
just dug out the spec of the server i put in a primary and its:
HP DL360 G7
1x E5620 Quad (dual capable)
3x 300GB SAS 10K Disks (600GB total size)
Server 2k8r2 license
this came in at £1800.00 and this was at the end of 2011
so i dont think your budget it that unreasonable
I'd say that SATA will do you fine, for that number of computers, or nearline SAS if you want to go a bit better. SAS is, IMO, overkill for your number of clients.
We've run our storage here off SATA for 7 years and it has been perfectly fine. We've shifted to SAS now, as we've doubled the network size since the SATA server was bought.
I'd say get plenty of RAM. RAM is cheap.
Storage is also cheap - RAID 10 is better than RAID 5 - so your plan is a fair one.
However, something to note here - the server you've specified doesn't have spare bays for 6 drives. It has 4 3.5" bays and a single 5.25" bay spare.
for me i wouldnt put SATA drives in a "front line" server not only because of the seek times etc but also alot of SATA drives arent rated as high in terms of the MTBF.
but as others have said your not dealing with a large amount of clients
having support for SAS later if your budget wont accommodate it the drives now is something worth checking
I'd simply whack a 600GB intel SSD in there for total piece of mind on the storage.
Virtualize it and take images for backups. Job done.
After doing much shopping around, Dell seem to offer the best value for servers. The following is what you can get for £1,117 exc VAT, inc Delivery:
PowerEdge T110 II Tower Chassis, Up to 4x 3.5" Cabled HDDs
1 Intel Xeon E3-1240v2 Processor (3.4GHz, 4C/8T, 8M Cache, 69W, Turbo)

Then all you need to get is a Windows Server 2012 licence: £99.12 from Phoenix Software (about the same price from most other license providers)
For Backups, buy a copy of BackupAssist and Western Digital Passport USB 1TB Hard Drives are £60 each - Get 3 or 5.
So this has 900GB of SAS drives (being Raid 5) and the option of adding a 4th drive in the future if you ever need more space, and a next day hardware warranty for 5 years. No mouse of keyboard, but you can get a decent cherry keyboard for about £10 and a logitech mouse for £5. Yes, I know the PERC S300 is a software based raid controller, but with the high specs of the server it has never caused any performance issues. These servers run fast and can be used as a PDC to run all services in primary schools without any issues, and offer good value for money.
For those suppliers saying your under-speccing I think the others a right, just trying to make you spend more as your spec will be more than able to support that many clients. I have a Primary 550 Users, just over 200 machines all run via 2 ML110 G6s with WD RE4 drives ( 4TB storage) and manage perfectly.
We've done pretty well with SATA here, they can be fine but make sure you have your RAID setup for any nasties! We run a pair of DFS-R file servers for our main share drives, fed by 6 7200rpm SATA drives each (RAID 1 OS, RAID 5 data). They're not enterprise class drives - 500GB Western Digital Caviar SE. First server was built in 2007, one drive failed in that time and replaced under warranty. With up to 400 client connections (spread between them), I've not had a complaint about the performance yet.
Would you guys go for the WD Red drives @ 5400rpm with read writes for ave 100mbs but with the added NAS/RAID features or Seagate Barracuda ST2000DM001 @7200rpm with double speed but no RAID/NAS features (baring in mind the ridiculously cheap price of these saving £90 a drive).
