for a testing and learning lab only I don't see any reason not to just work on everything. Telling people not to try out t/ftp or anything else just because "it's 2013..." is short sighted. The point is to learn not conform to your one specific thought process.

Though then you run into the issue of access to your lab being dependent upon the function of the lab. I'd prefer the ability to completely isolate the lab devices, but still being able to access each one. So for example even though I'm running vsphere I wouldn't want to manage vsphere through a VM hosted on vsphere. So for my lab since it's networking focused. I have all my network services plus console server on a single device I can access on my home network. by telneting to 10.1.10.254 and from there gong everywhere I need.

I'm not saying not to try out [T]FTP. I'm saying not to make it accessible on the same machine as the console server. Keep old, insecure protocols in their own DMZ in 2013. Set up a tftp helper for PXE (which is good practice for the CCNA anyway). Powercrazy posted:Totally a possibility.

There's CCNA in the title, but hopefully this thread is for IT labs of all types, including infrastructure builds and environment simulation. My lab was originally this: Until I the power bill started killing me, so I moved it into my colo space that I get for free by providing ad-hoc IT support for a friend. He gives me unmetered bandwidth on a 10mbit pipe, a half a cabinet and power. So I built this: But it's all my own gear so technically it's a private lab. I hope that's okay. Cabling The cabling might be hard to decipher, but basically I have VLANs for: Local networking Out of band management iSCSI Heartbeat. Gear list My current lab consists of a shitton of gear that I scored when everyone in my office was fired and the office itself closed down during a buyout. I was the last employee to go, kept around to dismantle and "eWaste" the gear and turn off the lights, so I eWasted a bunch of it into the trunk of my car: Dell PowerConnect 6248P gigE switch Sonicwall PRO 2040 Firewall / VPN concentrator Five Supermicro AS-1012G-MTF 1U barebones servers with 1 8-core Opteron and 16GB RAM - 2 ESXi 5.1 hypervisors - 2 Windows Server 2008 R2 hosts - 1 Windows Server 2008 R2 iSCSI target Two HP ProLiant DL120 G6 servers with 1 Quad-core Xeon and 16GB RAM each One HP Proliant DL160 G6 server with 2 quad-core Xeons and 48GB RAM I realize that this list is absolutely rediculous for a "home lab" but I'm posting it to give another example of what's possible. This lab is basically unsustainable since any component failure would require a $500-1000 purchase from eBay to replace and I'm not willing to lay out that kind of dough. Still, I have the gear now so why not use it, eh? Configuration The two DL120 servers are configured with IIS/MySQL/PHP and run small web servers as well as what might be the longest continuously running Quake 2 Devastation server on the planet (mind the broken links - when I moved this part of the web site to a new host the links broke and I haven't bothered to update them yet). One of the DL120s also acts as my vSphere server for the 2-node iSCSI-based ESXi 5.1 HA cluster. The DL180 server is an iSCSI target for the Hyper-V nodes and the ESXi nodes (below) as well as a Folding@Home rig. There is a dedicated LAN link, plus a pair of iSCSI links in round-robin load balancing for the target software. One of the Supermicro boxes is also configured as low-performance iSCSI storage, plus basic CIFS file sharing. ESXi 5.1 cluster - iSCSI based - 2 Supermicro servers (16-cores, 32GB total) VMs: - Windows 2008 R2 Domain controller - 2 SQL Server 2008 R2 Reporting Services servers on Server 2008 R2 - 2 CentOS Folding@Home servers Windows Server Failover Cluster Click here for a pic of the failover cluster manager. - iSCSI based - 2 Supermicro servers (16-cores, 32GB total) - SQL Server 2008 R2 failover Cluster - SQL Server 2008 R2 Analysis Services cluster - Hyper-V cluster VMs: - Exchange 2010 Server - Windows 2008 R2 Domain controller This lab is pretty much my Swiss Army knife, allowing me to mess around with iSCSI, basic networking, VPN tunneling, ESX, Hyper-V and database stuff. I don't have the biggest virtual environment, but it's enough for me to stand up random virtual appliances, do high-availability stuff and/or tinker with different OSes as my interests dictate.

That leads me to believe it's gns3 causing my troubles. The program works fine without any routers added but then it's kind of useless. No, if you're getting a blue screen or any other OS's equivalent it's almost never a user-level program. Not on any modern system, which Windows 7 certainly is. That means hardware or drivers, almost 100% of the time. If you're overclocked or running any oddball drivers (modified sound or GPU drivers, unusual peripherals, etc.) try disabling those first. If it still blue screens, start looking in to your hardware.

But, yes, an environment like that (2 routers, 2 servers, 2 switches) is a good idea.

Do you think it would be a good idea for me to host a small single server with 2 routers and 3 switches?All for practice of course. I think it is silly for IT folks to not have an IT lab in their home. It is very easy to get rusty on skills that you don't use every day and having the right gear handy is a great way to brush up on stuff (especially before interviews, etc). If I were to build a simple lab, I would build a white box ESXi host, stuff a bunch of nics in it, and then plug those nics into a router or two and a managed switch capable of multiple vlans. Stay away from the temptation to buy old servers (but free can be good!): They tend to be noisier and more power hungry than a whitebox build and you typically get more bang for your buck on a home built (plus you get more hardware experience). Here's a decent home ESXi server for around $550: ASRock 970 Extreme3 R2.0 AM3+ AMD 970 - $85 AMD FX-8120 Zambezi 3.1 GHz Eight-Core Desktop Processor - $150 2x8GB DDR3 SDRAM (16GB total) - $170 Rosewill capstone-550 80 PLUS GOLD power supply - $70 ATI Rage XL Pro 8BM PCI — $8 eBay 3 network cards: 2xPCI-e 1GB, 1xPCI 1GB — $~24 eBay Computer case - $50 You surely have old SATA hard drives floating around, right? Buy a USB key ($8) to install ESXi on and use your SATA HDs for storage. Make sure to buy the RAM in two sticks of 8GB each, so you can upgrade to 32GB at a later date by purchasing two more 8gb sticks when you can afford it. Then as your funding allows, buy a used Dell PowerConnect 2716 switch (~$80) and maybe a Cisco 2621 (dual-port fast ethernet) ($90) to allow you to route between VMs and vlans using hardware. Until you can get networking hardware, I think there are open source router appliances available for vmware that will get you designing your very own overcomplicated home network in no time...

Remember, You can run ESXi inside ESXi, there are some virtual routers and switches out there where you can make some really interesting virtual network which can mimic things like WAN latency/speed, failures, and many other things you won't have to spend a buck on. My advice start with one host, then move to another when you realize the host you are working on is not fitting the bill.

Unless you've done this before and know what you're doing, you almost certainly do not want a 1U with a 5 year old Xeon, no matter how enticing it looks on paper, especially if you want to do nested virt (which has improved dramatically from the hardware side in the last 5 years).

So there are a bunch of people telling you why this is a bad idea, but if you want to do the goon-in-the-well thing, be my guest. It sounds like you are kinda stoked on the idea of having Enterprise Server Gear in your house so go hog wild. Trust us, though. It will arrive in the mail and you will put your dives in and fire it up and get all kinds of excited about it. For about two weeks. Then eventually the fan noise will get annoying and you will start thinking about where you could put it to dampen the sound. Then you will start powering it off to get relief from the noise and power bill. Then you will be slightly irritated every time you want to try something and you have to wait while it powers on. Then you'll start browsing ebay to find out how much you can sell it for while you part out your new white box. The one with the efficient power supply, new processor and large, silent fans. edit: evol262 posted:It's loud, and it sucks power. It's loud. I cannot emphasize enough how piercing 40mm fans in a home environment. Nth-ing this. You think you know how loud 40mm fans are, because you sit next to some gear in an office and are used to the noise. But offices have a lot of background ambient noise that give context to server noise. The AC is blowing, there's people rattling around in the break room. Cubicle conversations, etc. You will get your new server home to your nice quiet house and no matter where you are or what you are doing you will always, always hear those 40mm fans.

I haven't build a lab yet. I think it is absolutely essential to have my own lab so I can keep up and learn more. I am familiar with Oracle virtual box. but I am looking to buy something like this http://www.ebay.com/itm/251269644666 I got all the Microsoft licenses I need from my school. (dreamspark) I also want to learn about differential and incremental back ups. (I know how to do full back ups efficiently now and I know the difference between incremental and differential. I don't know how to implement them.) I think I need to use tapes for this. I have zero experience with tapes I also need to learn more about how to manage network cables. like how do I get 1 switch to connect to 20 computers in different rooms. the cables should go through the wall right?. I have no idea how to do this. I am willing to learn this at my home by drilling holes or however it is done. I know nothing about Cisco at the moment but I want to learn it as soon as possible so that is also a must for me. I also need to learn how to make a VPN. These are the things I know I want to know. there is so much I don't know yet outside of this. I want to build a machine that can let me learn all things and more. Is this reasonable to build and if so could you guys point me in the right direction?

On the other hand, if you manage to borrow a modern tower server from work, it'll probably be quieter than your normal desktop. The T720 I have is hilariously quiet for how many fans and hard drives it has. ...until it ramps up when it's 90 degrees in the garage.
