back to article Clash of the Titans: Which of you has the GREATEST HOME LAB?

Last week's article about home labs and their career-enhancing powers produced some interesting comments from readers about their home labs. That got us thinking: in the spirit of our infamous Ventblockers series, in which readers sent in gut-wrenching photos of filth-laden IT kit, what about a servers'n'sofas challenge to show …

CriKit

I got tired of the loud, hot rack in my office and built CriKit. I routinely run 5 - 30 virtual machines and I can gen up any Private Cloud software I want because that is my interest right now. It doesn't do everything however, live migration of large VM's kinda sucks over 1 Gbe, but the compute nodes have enough compute power and memory to do a lot and the SSD's make things snap nicely. I use the same proc as SeaMicro did in their first release - Intel Xeon E3-1260L with 8 MB of cache and it is an awesome combination of compute horsepower and low-wattage. Cheap, cool, quiet, compact and fast enough is all I was looking for. Gotta admire the guy with the 47 U kit though.

I'd turn it around

The greatest homelab is the one which gets you the results you need. And that is usually hardly dependent on the kind of hardware you're using, but more so on how smart you've set everything up.

I think there needs to be multiple categories....

... for the awards. Then it can be as prestigious as Oscars or the Razzies:

eg:

Best home lab drawing under 50W continuous

Best home lab based in *occupied* primary entertainment area of the house (Lounge and Bedroom subcategories)

Best home lab that the partner has destroyed because they are sick of the noise

etc.

We've got a couple of HP microservers running zfs for file storage, a couple of ARM boxes repurposed to DLNA rendering, two desktops, a myth box, a laptop, a netbook, an ARM chromebook, three consoles, several mobile phones, a smart tv, a smart blu-ray player and a few squeezebox devices all on a mix of wired, wireless and powerline network segments. Uh I think that's about it.

These pretty much all count as part of the lab these days. They're all running some flavour of linux apart from the consoles and one of the desktops...

How many of you (well of us actually now I think about it) are planning to show partners the most egregious listings to our partners in the hope of reducing the domestic criticism of our own much more modest setups?

And how many of us are hopelessly optimistic enough to think that doing so might have the slightest effect on said pressure from 'er/'im indoors?

The list of shame

2 HP ML110 G6 servers (nice a quiet, I'd recommend these for home lab work)

1 HP ML110 G7 server (noisier than the G6 boxes, but much nicer inside)

2 HP MicroServers, these are the "production" boxes, so do they count as home lab? (really quiet, should swap the disks for SSDs and then they'd be all but silent, wish they had more PCI slots)

various Dell PCs, ones ever suffering from Windows. The rest have various versions of CentOS.

1 HP EliteBook 8730W only 4GB of RAM in this one.

1 HP EliteBook 8740W with 16GB, SSD... etc.

1 HP 2133 netbook

2 HP managed switches, can't be arsed to crawl around on the floor and find the model number, they're fanless as 1U high fans are too noisy even for me.

Oh and a network managed extend run UPS.

oh yes and two laser printers.

Then there is the Pièce de résistance, I've also got an HP85, with a still working tape drive and printer. I need to track down an 7550 to go with this.

Plus

1 HP rx7620 with 8 Maddison Itanium2 CPUs and 56GB of RAM

1 HP rx5670 with 4 McKinley CPUs and 8GB of RAM

1 HP rx2400 with 2 McKinley CPUs and 12GB of RAM (this runs an Oracle RAC cluster inside VMs)

the VA disk array

Really can't remember how much FC JBOD disk racks (I just gave away all my SCSI boxes)

2 DL380s

No the startup spike always takes out the circuit breaker, some of the boxes are on cut out switches these days which makes it easier to recover from power outages. The production boxes are on UPSs which are good for 4->6 hours.

"Not a real OS" but........

....quite a handy home lab platform.

For years I ran a motley assortment of PCs with various OSes - but I recently managed to wipe the slate clean, and consolidate the whole lot onto 1 box.

I can boot Win7, W2K12 server, Linux Mint 14, and an Ubuntu cut that I don't like, won't use, and will probably delete soon. And I have the capacity to create whatever other x64 OS variants I want - all conveniently available, all on my main (now only) desktop PC.

Good riddance to KVM switches and noisy old legacy kit - hello Windows 8! Hyper-V available in the desktop product is one of those "under the hood" features that can turn out to be really useful - certainly was for me.

Haterz can downvote me to their hearts' content, and no doubt will - but the verifiable facts speak for themselves. Cheers!

PS - I even cobbled together a selection of left-over kit, and flogged it as a working PC for £220 beer money.

Re: "Not a real OS" but........

I've gone through my own consolidation. I have a bunch of old PCs of various vintages in the loft space all of which I now use for long term storage only now. I replaced them all with a single model B Raspberry Pi with a couple of 2.5" drives running Slackware 14. It's got a printer attached and all the other PCs are set up with wake-on LAN so I can get stuff off them if I need to.

That and the 6 42U racks full of crap I have at work. Their electricity bill, not mine.

During the move...

I basically got rid of all my old, hoarded machines (Best being a P3 800) now i just use my laptop with virtual machines. Its not nearly as much fun and it really doesnt look as cool as old machines doing things with no cases on them and loads of wire everywhere. Such is progress...

(Mind you its a lot quicker to tidy away and SWMBO doesnt moan as much about my experimentation :D)

Not hardware but uses...

Can't help thinking that yes the hardware is fundamental and interesting, BUT the uses that we make of it are even more interesting. For example, all the usual suspects, the exotic, and possibly some "save the planet" grid computing like those available through Seti@home, Einstein@home & etc. So, how about a list of dazzling uses!? Always love tuning in on you guys. Thanks, Erin in Rowayton

Good to see at least one HP Microserver. How about a USB-WiFi capable VM router?

Running at less than 100 Watts, I have two domain controllers, an Exchange server, a reverse proxy server, a firewall router, and a separate video hosting server in a HP Microserver based on this:

http://techhead.co/running-vmware-vsphere-on-an-hp-microserver/

Only I use an Adaptec SAS RAID controller instead of the onboard SATA; it turns out the internal drive cable plugs right into the Adaptec card and I can use the factory chassis with bog standard SATA drives. I matched that with 8 GB RAM and a VLAN-capable HP switch. It's a data centre in a shoebox.

The only thing I'm missing is software to turn a USB wireless dongle into an access point. I'm already using Zeroshell as my router, which has some wireless device support but no USB support and no IPv6 support. Can anyone recommend a good x86 router that runs on a virtual machine?

(While Zeroshell can do wireless AP with a PCIe card, the Microserver chipset doesn't support Direct Path access to a PCIe device.)

Not in the same league

It's not really a home lab, but I do have what used to be my old gaming PC, re-purposed into a storage server, mainly by ramming as many harddrives and fans into the case as possible.

However, as I sold my old CPU, it's currently running with a water-cooled Sempron. I suppose I could have pulled the water cooling out, but why bother?

Now I come to think about it, I don't remember topping up the water in the last few years, better check that out...

Mine's all Enterprise-class boxes (DL580s and such) but pretty dated.

All I care about is I can sim stuff that would require change requests to do at work - even in test and dev, believe it or not.

So I agree that at least some sort of lab is pretty much necessary if you want to keep up, but it's also vital [i]just to do your job[/i] in some circumstances.

Re: change requests

We used to have that too, a full change advisory board for the regression systems, but not for the dev test systems.

I can see both sides, pros and cons for it, though nowadays (and after a department reshuffle), the regression CAB is gone and the dev test and regression areas are under our control now too (I used to be previously in a team working with DT and reg env, prod was different team, now am in said different team, controlling all). DT and Reg changes now go much faster and makes life easier :)

Last night we counted how many computers were on one floor of the house. We reached ten and gave up. Our house has 2 more floors and a basement; no telling what else lurks in it. We really ought to get motivated and make it all into something, because having a "lab" would at least make it sound fancy instead of a case of hoarding.

"Home lab"

Well, it's more of a collection of boxes doing stuff.

Initially I had a Q6600 box running Windows Vista (indeed!) and had a chance to grab an old box from two jobs ago (basically 5 years ago), an old AMD XP 3500+, running Debian with 2GB

Nowadays the Q6600 runs Kubuntu 12.04, 8GB RAM, GeForce 260 (previous gaming box), and the AMD is still the same, doing same, being file server and basically web server for the bit of (private) web development I do (used to do professional, not anymore), while the Q6600 can run VMs and also SMB shares (store for music and all)

New box is an i7 Ivy Bridge 3770, 32GB RAM, SSD + HDD. Next to gaming it's also there to run VMs (and other hobbies e.g. 3D Rendering).

VMs across boxes I want to use (next to above Web dev) to focus on things I will be doing more at work soon, such as penetration testing, securing / hardening Linux systems, vulnerability scans, exploiting web interfaces, breaking vulnerable packages over the network, play around with log storage from my home machines and servers across a couple providers I use. Next to that any other Linux sysadminy thingy I can think of which looks interesting.

Got three unmanaged switches, two are hand-me-downs 100MBit, the latest finally 1GBit. Looking into sourcing some (older) Cisco switches to start playing more with VLANs around coupled with above stuff.

6 screens to provide full overview of things, top left and center go to the Q6600, top right goes to the laptop docking station (an i5 from work with 8GB for more playing), bottom three go to Win7 box (Mostly though for nVidia surround gaming ;) )

I'd be lost w/o Synergy in cases like this (absolut win of a program)

So it's somewhat a mix a of a "lab" and gaming station. As I'v e mentioned in the previous article which spawned this one, the biggest winner is probably British Gas here...

Maybe some more detail on my setup

Well the NTP server was already mentioned. It gets it's time from a GPS receiver.

It also has 4 DVB-S2 tuners and acts as my "PVR". Of course it has about 3 Terabytes of disk in a RAID-5. It also acts as a streaming server to the "Freifunk" network.

My main computer has ECC-Ram (16 Gigabytes) as well as 8 2 Terabyte disks running in a RAID-6 configuration, something I wouldn't do again.

Other than that I'm running some OpenWRT-based routers as part of the "Freifunk Franken" meshed wireless network, and a rented virtual server running outside handling e-mail, web as well as an Asterisk server I like to fool around with. :)

My current Internet router is some random Atom box connected to the DSL modem. It also runs a transparent proxy for fun and provides me currently with IPv4 and tunneled IPv6.

i5 2500k - 16Gb RAM - 120Gb SSD - 1Tb

HP MicroServer N36L - 8GB - 2x1Tb 1x2Tb

Getting shot of it all and going for a i7 3770T, 32Gb RAM, Q77 board, and another 120Gb to plonk it in RAID0 for VM storage, and then shove all the TB disks in and RDM them to the various VMs. Should run nice and suck very little juice.
