Also I noticed you mention a blade server, but these are built to be efficient use of space- space isn't a big problem for us so we can go with a rack instead- am i right?

Is there a point at which adding more RAM isn't really neccesary? It said the R905 can fit 256gb in total, but surely once I hit 64gb that's more than enough for the kind of tasks I'm doing? Or is it a case of more the better?

Where are you hosting this? If it's a datacenter then surely space is an issue given prices these days which makes me worry your considering hosting this in your office or something, in which case just stop and rebudget things including colocation...

VMs - the more RAM the better, most of our VPS hosting boxes have 96GB per blade (partly as when they were designed memory oversubscription made them dog slow) and we only stopped there because they don't support any more.

Dell R610 are looking good, put in two processors, 32 GB Ram and 6 x 300GB Sas drives would easily run what your talking about. All comes in about £4,500.

Raid 10 the 6 drives and you've got just under a terrabyte of highspeed redundant storage.

That would run shed loads of VMs without even straining. Just make sure you have good network switches (but you have another £500 towards something good).

We don't really need storage to be completely honest, we aren't doing a datacentre kind of service it's a really niche one.

But to give you an idea of what are requirements are, I'm thinking something along the lines of 10 WAN connections coming in on the network, then 100 total concurrent users (maybe 10 on each). Due to the light load on each user (no heavy apps) just things a basic user would do like browsing, then I believe 100 users is possible once we maxed the box with 4 processors and 256gb ram.

But in the beginning we will just have 1 processor, and 16gb ram with 10 users.

Well without knowing what you're doing it's difficult to say more but personally I'd laugh at anybody providing a hosted service outside a datacenter today (and given the number of potential customers who want to tour our datacenters I don't seem to be alone). 10 WAN connections also sounds a very bad solution, given you won't likely be able to load balance them you'll end up with one maxed out and others unused at times of the day. You'd be far better with one serious connection (which would also be more reliable...)

At home of course :p
I see a few people have recommended the R610 - they really are fantastic.

I'm going to buck the trend through and recommend the R510. They take 14 drives in total (2 x 2.5" cabled drives internally, and 12 x 3.5" drives externally). They also take up to 2 of the core i7 based xeons, loads of ram, and also take the new Perc H700 raid card which is 512mb cache and takes SAS/Sata 6gpbs (sata 3).

We have just taken delivery in fact of a R510 which came with 2 x cpu's (shows up in task manager as 16 cores), 24Gb Ram, and 6 x 300Gb 6Gbps 15k sas drives in Raid 50. We then bought 6 1Tb Samsung F3 drives to populate the remaining 6 slots to get a second Raid 50 array up and running. Shed loads of power and storage and it was under 5k once we squeezed our Dell account manager :)

We use Dell R610/R710 almost exclusively these days. Typical spec:-

2 x 2.26Ghz (16 virtual cores)
24GB DDR3
8 x 300GB 2.5" 10K SAS

Excellent bang for buck. :)

What RAID card are you using for that? I was under the impression you had to use one of the H series cards which means you're limited to Dell's own drives?

The sweet spot in terms of price/GB is 2 or 4GB sticks. Once you get past 4GB sticks, it starts becoming cheaper to provision an extra node.

Looking at the rack servers is great, but do you have a rack? Have you got space for a rack? If not that's £1600 on top for a 24u rack and then finding a space for it.

Where do you plan on siting the server, trust me, you wont want it in the same room as you as the whine of the fans will soon get on your goat, even if you do go for the tower it will be loud! Steer clear of blades and blade enclosures for this reason.

Do you have air-con sorted out? Running a server in the middle of summer when it's 25-30c ambient air temp in your office will get the server nice and toasty! Without good air-con, again steer clear of blades. (again, i know the jokes about UK summers, but if you are serious about being in business you need to consider this)

What about power supply and UPS, servers are a fair draw when running? And if you have a power cut you need something to keep things running whilst they shut down nicely, rather than a lot of blue screens and data loss.

What about switch(es) to plug it all together?

Looking at the Dell site, i'd personally say go down the route of the T710 range if you still want to, it's a tower, can be tucked away and also converted to rack mount in future if you do get rack space later on. Dual processors, 16gb ram, 6 HDDs, dual 4 port ethernet, dual power supplies comes in around £4k + VAT. (and that's with 3yr next day support, do you need same day? if so, add another £800)

You gave a small smile when asked about O/S, it's not to be shirked away from, it's not only the O/S you need to think about, but also the VM software (VMWare isnt cheap!)

Also for internet, there are a few options to look at, but to give you an idea on pricing for a semi-decent setup, i just got a price for a 10mb internet connection hosted at a data centre that is delivered to my sites by two 10mb bearers giving 5mb across each (if one fails the other speeds up to 10mb to ensure i get the bandwidth i pay for). Set up is around £10k and annual rental around £20k.

I spent all day Tuesday taking delivery of and installing some 47u racks into our new Bristol office.

Big racks plus big UPS to go in the racks didn't make it a fun day :p

Nice, it's sometimes good to be the boss...... I'm now the guy who walks in whilst your all hot and sweaty after getting though a few racks to say "Haven't you finished that job yet????? Back in my day, when racks were the size of small skyscrapers and UPS's were the size of a semi detached house i would have had that lot done in an hour AND eaten all the packaging for lunch!" :D

I volunteered so only myself to blame, plus he'd never dare say that, he was grateful we were there doing it :)

Although what does hack me off is when I'm lying on the floor trying to tighten up a nut that doesn't want to be tightened and the boss calls (who is sat 100 miles away) to say 'we've had a complaint that you've left the pallets outside can you sort it out now'.

Fussy beggers :p

Not to cause grief but have you considered going for a hosted service? If you are starting a new venture you don't want to be sinking capital into assets.

Rackspace offer a multitude of options.

Why are you spending 5k doing this? Seems like madness! You (and your customers) would get better value elsewhere. You just don't have the volume yet to warrant putting such system in place.

I also worry that you originally started talking about i7 processors. I don't want to be rude but your knowledge of this sort of thing seems to be limited. What are you going to do if the hardware fails? Do you have another system, with equal capacity, ready to take over? Where will you be backing this all up to?

If you still insist - the Dells are great. We have a number of R710s. We also have a number of HP DL380 G3/4/5/6. All good machines and reasonably priced, IMO.

Good luck with your venture.

I nearly through some rails out the window the other day. Our rack doesnt have rear or side access so any rails that need to be bolted in place is a proper mission, especially when the rack is already got some kit in it, you need to contort your body in all sorts of ways to lean in, hold the rail and try and get the bolt in.

I finally got my technique down and got one in, only to then discover I had made the amateurist mistake possible and mounted the damn thing backwards so the slide just hits the back of the cabinet :mad:

Apparently you could hear the cursing from the next room.

I do have to agree, speaking to a decent managed hosting provider would seem a good idea, it'll mean you get decent hardware, configured correctly in a decent environment with decent connectivity and you'll be able to pay monthly, which should improve the cash flow situation if you're selling it on to your customers (money in the bank beats assets any day...)

Your best bet for uptime is two decent £2500 boxes, each probably with a decent 4 or 6 core chip and 12GB of RAM, then 4x 300GB SAS drives in RAID10. That lets you split the VMs so the backup of the service runs on a different physical server to the primary, a single server will break one day, no matter how high end it is. You should get something like that out of Dell or HP for £5k if you have a reasonable discount level.

This. A single server for ultimate uptime is a daft idea
