Sorry if it's a bit too broad question...

I'd like to have my own personal server, mainly for php websites (although I might later add some features when I'll need them... like Jabber, mail, etc). I might later decide to also offer some space for clients, but for now it will be for my own use and tests. Its main role will be LAMP.

The thing is that I never worked with 'real' server hardware... I know how to run server software, etc, but now I only have my desktop home pcs, laptops, etc... And I would like to buy some good quality hardware for this setup (so after I'll learn enough I might try to also offer some space for clients).

By hardware I mean:

  • powerful server like for professional hosting setups (where i can change faulty components live without rebooting it, etc)
  • emergency power source? how do i get something like this?
  • i guess reliable server should have backup? good cooling? good UPS?
  • anything else that is important in powerful setup that you could recommend?

Also please note that I'm not interested in VPS reseller, I would like to learn with physical hardware.

Comments, links to example hardware stores (I mean... where do I get this stuf?? Hah) and links to any external resources will be helpful.


About hotswapping software support - I would probably use Debian as my OS.

Noise... what about it? I would probably like to have my server where I live.


What kmarsh said, plus

  • 64bit, with more than 4gb of memory
  • A Remote Console solution (ILO/RSA - NOT something like VNC - you need hardware level remote access) if you're going to locate the server somewhere you can't physically get to it 24/7
  • Multiple NICs (at least 4), that allow NIC Teaming
  • The most important bit: Maintenance Contract (4/8/12hour response time etc)

    +1 oh, yes, maintenance contract! – kmarsh Jul 10 '09 at 16:33
  • You could say "Remote Console" or something more generic than ILO/RSA. I also don't think "every" server needs 4 NICs, especially just starting out. – sclarson Jul 10 '09 at 16:34
  • Depends on how serious you want to be. We team the NICs into pairs, and each pair is a Smart Load Balancing & Failover team plugged into separate switches. Peace of mind. Also, most pizza-box servers come with 2 NICs onboard. It isn't going to break the bank to shove in an extra card with 2 NICs – Izzy Jul 10 '09 at 16:41
  • thanks Izzy, kmarsh, Kevin... great answers, I'll vote you up when I'll have enough rep to vote – Phil Jul 10 '09 at 17:48
  • Can you accept an answer for this thread with low rep? – kmarsh Jul 13 '09 at 17:44

Any server:

  • Should have ECC memory
  • Should have 2 power supplies
  • Should have at least a mirrored pair of disks or 4-disk RAID 5 with hot spare plugged in.
  • Should have room for growth of RAM and storage (external OK), for example an slot free for an FC card or free SAS ports and room for more disks.
  • Should be on a UPS with more than sufficient runtime to a.) endure a typical power outage for your area (say, 10-15 minutes) plus time to shut down (another 10-15 minutes).
  • Should have a backup solution integrated from the start (can be external)

The fastest servers are rarely as fast as the fastest gaming systems, nor do they need to be. Servers are more about capacity and throughput, while gaming systems are more about reducing GUI latency. Indeed, most servers have fairly lame graphics hardware.

Form Factor

I think that you'll have better luck with what you're talking about if you go for a rackmount server. However, those are noisy(they typically live in a datacenter where people aren't, so it's not usually a problem).


You'll want a UPS & possibly a generator outside for those times when the power goes out for a while, although depending on reliability of power, you might be able to get by with just a UPS. APC has some good ones, and they even have a sizing guide.

Hard Disks

kmarsh mentioned RAID 5(3 disks) although RAID 1(2 disks) would also work. Going from 1 to 5 is a speed boost.

Power Supplies

kmarsh also mentioned redundant power supplies. You should definitely get those.


Dual NICs are also a requirement. Linux can bond two NICs together so that it looks like one address. You'd then connect these to redundant switches/routers/firewalls so that either of them could go down without affecting uptime.

Hot Swapping

You mention that you'd like to change faulty components without rebooting; that's known as hot-swapping. That's commonly found in a rackmount.

For all the peripheral components(power supplies, HDs, DVD/CD drives, any floppy drives, & memory), you should check with the manufacturer that they're hot-swappable. Hot swapping has to be supported by the host OS, the motherboard, & the component you're swapping. You mentioned Linux; that does support hot swapping. We use Dells for all of our hardware; they have pretty good support. Also, the support we have will make sure that everything is hot-swappable.

Remote Access

We also have Dell RACs in our servers; the Remote Access Cards allow you to remotely power on/off/reboot the server, connect to the console, or put in a CD without being there. It's like being at the console without driving/flying out there. About the only thing you can't do(that you would be able to onsite) is to replace faulty hardware.

    "You mention that you'd like to change faulty components without rebooting; that's known as hot-swapping and I think that it's more commonly found in a rackmount." False. These features are more commonly found in good servers regardless of the case style. I have two Dell PowerEdge systems that have hot-swappable power supplies and hard disks, but are not in rack-mount cases. – phuzion Jul 10 '09 at 16:44

    @phuzion: Whoops. Now that I think about it, we have a customer that does that a lot. Thanks. – Kevin M Jul 10 '09 at 16:50
  • Cool, I'm using APC on my PC xD. That's something I didn't thought about... noise. How noisy usually servers are? Is it possible to limit noise? Any suggestions? Btw I'll probably want to use Debian for it (I think... that's what I have most experience with) – Phil Jul 10 '09 at 17:25
  • Noise! This is a factor. For example, Sun "T" servers are VERY noisy. I wouldn't want to work beside one all day. – kmarsh Jul 13 '09 at 17:46

I recommend a DL100 or DL300 series from HP. Get dual power supplies, hardware RAID controller, lots of RAM, and some nice disks. You'll be able to swap disks and power supplies without downtime, and having dual power supplies allows you to move to different power circuits / UPS feeds without downtime too. It will also come with an iLo interface for out-of-band management magic. Those are the main features of "server-class" hardware, IMO.

Next, buy a nice quarter-height rack with some integrated fans, and put a small UPS in the bottom of it. Throw away all of your DLink gear and buy rack-mountable SOHO routers and switches. Buy a variety of lengths of Ethernet patch cables, and a bunch of velcro cable ties to make it all purty. APC has very nice stuff for this.

  • Actually if you can get them before they are gone, you can get great deals on the HP ML 150. – Jim B Jul 10 '09 at 17:10

Your best bet is to find used hardware on Ebay, actually. In fact, that's what we use where I work - we don't have an enormous client base, so there's no great need for super-powerful, cutting edge stuff. What we do need however, are servers that are super-reliable. Most of our servers are various models of Dell Poweredge servers. 2450's are what we use for our DNS servers and our own website and even that is overkill. But they're also very cheap and fairly easy to find. We have a 6650 for our hosted websites and that does its job well, even with several popular sites that use CMS's like Mambo.

Yes, you'll need a good UPS and cooling and backups. The UPS might also be something you can snag on Ebay, but you'll have to make sure the batteries are new. I have no idea where you could get a bargain on air conditioning though. We use a consumer-grade computer in a server case for our backup machine (hard drives are cheap, tape drives are expensive, and you can't automate them worth a damn anyhow). The backup machine could go up and down like a yo-yo and your customers won't notice. And if the drive fails (or if you really like, the software RAID array) then you have until your next data catastrophe to replace it. 6 hours of downtime on this box is also something your customers won't notice.

Now, the bill for all this... will likely be more than a beer budget. For this reason, I don't really know why you don't go in for formal training, because the tuition would be about as much, and you'd probably get to work with newer hardware. Moreover, there's nothing to it. This kind of hardware is so reliable that you hardly even need to interact with it, and you just end up going by what the manual says. The software on the server will be much more complicated, in fact.

  • I don't have anything against paying more and starting out with completely new and fancy hardware. I'd like to have as much fun with it as possible, investing in hardware isn't an issue for me. I'm also not that much into training at all... rather wanted to explore something new and interesting by myself. Thanks for your suggestions, though. looks at specs – Phil Jul 10 '09 at 17:38
  • If you buy on eBay, you have no service warranty, which means you will have to purchase your spares ahead instead of rely on 4 hour service contracts. That can eat up a lot of your savings. – kmarsh Jul 13 '09 at 17:47

For play at home (and your learning process), buy used as Ernie and some others have said and by all means use it at home. It won't be quiet - most proper servers sound like a jet engine when they are starting up.

For anything where you are hosting for your clients on the Internet however, renting is always better than buying. You aren't going to have a diesel generators, multiple power grid connections, multiple internet connections, N+1 UPS, N+1 cooling, everything.

  • ...well, yes, actually what I'm asking about is how do I get diesel generators, multiple power grid connections, multiple internet connections (hmmmm? maybe that's really something to think about. didn't thought about it...), cooling, etc. I mean - some people are actually starting these datacenters, eh? All those resellers have to buy from someone ;). I'm trying to learn how to be that 'someone'. Btw if you're saying they're terribly noisy then I would need separate building? – Phil Jul 10 '09 at 17:43
  • Well, like a jet engine but not as loud. There may have been an exageration there. Know what I reccommend? Check out a site like telco hotel and find a nearby facility. Find a provider in that facility, and ask for a tour (assuming you haven't done that). – Kyle Hodgson Jul 11 '09 at 1:43
  • www.carrierhotels.com for instance. – Kyle Hodgson Jul 11 '09 at 1:48
