Go SDDC Lab is my personal home lab, it has evolved over the last 9 years to its current “streamlined” form.

As a strong believer of nested virtualization (I was amongst the firsts outside VMware to successfully run nested ESX hosts on VMware Workstation back in 2007) I wanted to keep everything running using a “layered” approach.

The lab currently consists of two hosts, a small one called “minion” and a large compute host called “monster”. Minion is a Mac Mini 6,1 with a single dual-core i5 running at 2.50Ghz and 16GB of RAM, the Mini hosts both a regular 500GB SATA drive and a Samsung EVO2 120GB SSD that is being used with vFlash Read Cache.

Monster is a Dell R910 with four eight-core Nehalem-EX CPUs running at 1.86GHz and boasting 256GB of RAM, the host doesn’t currently have any internal storage and I’m looking for sponsors to add a PCI-E flash device to it to test new use cases.

DA MONSTER!

I keep a layered design on monster, Layer 1 runs directly on top of ESXi 5.5 installed on Monster and holds the complete VMware vCloud Suite, then a specific resource pool holds all the hypervisors that provide Layer 2 (a mix of released and beta ESXi, KVM hosts and even Hyper-V) that are used to provide a “sandbox” for tests and such.

Hypervisor layers

Storage wise, the VMs are sitting on a NetApp FAS2020 with 12x 15K 300GB disks, enough to sustain decent performance during deployments, I’m currently looking for a replacement for this piece of equipment as I want to have an array that supports VAAI.

On the network side, the virtualization lab is served by a trusty HP1800-24G that switches packets for the core gigabit network, there’s also a physical Cisco lab that is currently not interconnected to the virtualization part, in the future I plan to utilize the Cisco gear to simulate an MPLS WAN to separate sites all running on monster.

The connection to the outside world is served by a Cisco 2811 with three different WAN connections (two ADSL2+ and a backup 3G network) that also doubles as SSLVPN endpoint and a BlueCoat PacketShaper 3500 that performs QoS on the WAN.

And, being a screen estate lover, this is my work desk, also dubbed, the “control room”
