(An update to my original post on home labs HERE)
You’ll learn that if you create a home lab it will always be evolving. I had a different vision for my lab when I first started and now I’m on my home lab 2.0.
First thing I realized is that I wanted both hosts to have equal resources, so I balanced them out with 24GB of RAM each (Hopefully will upgrade to 32GB shortly). The next step was getting rid of the 1TB Raid1 and going with a 4TB Raid5 and a 256gb Samsung 840 Pro SSD. I realized I would need more space than 1TB for what I was doing and storing, and I wanted the Read-speed of a Raid5. The SSD is fantastic as well.
The third step I took was to enable Jumbo frames on everything. I upped the MTU from 1500 to 5000 and saw a great performance increase (20MB/s to roughly 120MB/s) before tweaking anything else.
I have a DNS server in my lab but I decided as well to setup a 2nd DNS server on my Synology DS412+ since it is always on regardless of the state of my hosts. I also setup a Syslog and VPN server on my Synology for other purposes as well.
Now my lab currently looks like the following:
- I7-3770 CPU
- 24GB Ram
- 8GB USB Flash drive (boot and logs)
- 1TB internal HD (because I had them laying around)
- connected to Synology LUNs (SSD iSCSI, SSD-NFS, iSCSI on Raid-5)
- **Note** The version of ASRock motherboard I am using doesn’t support VT-d, however the next step up does but will run you another $50+/motherboard.
1 optional host:
- I7-2600 CPU
- 16GB RAM
- 8GB USB Flash Drive (boot and logs)
- Connected to Synology LUNs like those above
1 Synology DS412+ NAS:
- 3x Western Digital Red 2TB 7200 RPM 64MB Hard Drives
- 1x Samsung 840 Pro SSD 256GB Hard Drive
- Not currently using link aggregation but using Jumbo Frames
- DNS, Syslog, and VPN Server (also connected to Amazon Glacier,not active)
1 TP-Link Gigabit Unmanaged 5-port Switch
1 TP-Link TL-WDR3600 Gigabit router (running DD-WRT)
Total Cost was roughly $2,400
All in all this is a very sturdy build. I am currently running roughly 10 VM’s 24/7 and have the capacity to be running probably triple the load. I am currently installing and configuring vCloud Director and Nexentastor for de-duplication.
MORE TO COME!
