Luckily I have super cool teammates, but if you aren’t so lucky you’ll need to beg, or bribe them with their favorite adult beverage. Here I was able to get a new subnet (/24) that was all mine. Those guys horde IP addresses, subnets and VLANs like you’re stealing from them personally. The goal of the lab is to get creative and use what’s available to you. You can even use vSAN if you can manage to meet the HCL requirements.

You could acquire a third server and setup FreeNAS, or even a Windows server as a NFS or iSCSI target. Now, if you aren’t lucky enough to have extra storage available, there are options. The storage guys were generous here too and carved out some storage for me. This environment also has NFS storage available. I was able to get the storage guys to give me a couple of 10GB boot LUNs for my hosts, so we’re in business there. However, if I didn’t have connectivity, I would have gone with the extremely cheap alternative of booting from SD. I can set these up these two blades to boot from SD or SAN, and since the chassis is already connected, I’ll boot from SAN. You can get these servers (or something similar) refurbished all over the internet at a substantial discount. YES! Two dual socket, 8 core, B200 M3s with 96GB of RAM each. I managed to find two blades that were shut down and not in use in a UCS chassis. It doesn’t have to be anything earth shattering or beefy. I touched on this briefly above, we need some modern hardware. I wanted our team to be able to jump into the lab and deploy a nested environment to test upgrades, or deploy the newest version of product X, etc. So, when something new drops, like the next release of vSphere for example, our team needs to be on top of it. I work on a delivery team where we design, build and implement solutions for customers – simple or complex, it doesn’t matter. So why am I writing about this? It’s not a secret that every IT person struggles with this topic. There are work arounds, and you might not make some new friends, but hey, this lab is important! Yeah, I know, I’m not saying you should go all shadow IT. Yeah, I can hear you now “but the security team…the network team…corporate policy…blah blah blah”. The easiest business case to make is one that is virtually free, or severely discounted. Yep, ESXi on top of ESXi – let’s virtualize your virtualization environment! You can get away with a couple of blades in an existing chassis, or a couple of older rack mount servers – maybe it’s a little older, maybe it’s not quite as powerful, the trick is getting hardware that isn’t ancient.

But, you don’t need to match production, you just need something relatively modern, and then take full advantage of that sweet sweet magic called virtualization and build a nested lab. I’ve spent the bulk of my career building labs out of old equipment and hustling for extra RAM and storage.

Us nerds just want extra servers to play around with, I know it! Managers don’t see the ROI and don’t want to make room in the budget because they think it will cost a fortune. The problem with labs is that companies typically don’t see the value. If you do have a nice lab, you’re certainly in the minority – hug it and squeeze it and pet it and call it George! Never let go.

If you do have some sort of lab, it’s probably hand me down gear that’s in shambles with so many problems you can’t remotely attempt to mimic anything in production.

Let’s face it, most companies don’t have Labs for you to learn new software and operating systems, let alone test upgrades and changes to your existing environments.
