My Home Lab N40L

I just recently got a good working home lab up and running to help me with study for the VCP5 and VCAP5 VMware certifications. I have found it extremely helpful with studying as well as testing some theories for the production environment at work since they will not give me a good lab to play with there.

So I started with a HP N40l Micro Server.  It shipped as HP ProLiant N40L MicroServer Server System AMD Turion II Neo N40L 1.5GHz 2-Core 2GB (1 x 2GB) 1 x 250GB LFF SATA 658553-001.  I knew that the 2gb memory was  not going to be enough so I followed this great post by Chris Wahl and changed the memory to 16gb. The server has 2 CPU and one onboard NIC.  I am sure that I will be needing to add another host soon.


I installed ESXi 5.1 to get started then installed Autolab 1.0.  I am having trouble installing ver 1.1 so I will leave that for another post.

As I started working with the lab I found that storage was keeping me from doing some of the things that I wanted to do so I got a 1TB Western Digital Green HD to add to the server.  Now I am finding that I have the storage to do what I wanted to do but the IO is horrible! So the next step is to start rounding up some stuff to build a cheap NAS.  Hmmm another post.  The more I work with my new lab the more things I start thinking about to post.

Till next time.
