As mentioned in my previous blog, I started to rebuild my necessary home systems. Last year I was running some servers in my home lab, but my power bill was a shock! I decided to replace everything with a HP MicroServer. Since two months my HP MicroServer is doing a very good job. :) It’s a very fast and economical system. It consumes about 76 Watt. I installed four 2 TB Seagate disks and connected them to a HP SmartArray P410 controller with 512 MB BBWC. The storage is incredible fast. I’m running a RAID-6 ADG with 4 TB usable capacity. VMware ESX 4i is booted from an USB stick. My file and media server is entirely virtualized. I used CentOS 5.6 as base system and attached four 1 TB virtual disks. I grouped the four disks with LVM2 and my data is striped across all disks. An additional CentOS 5.6 system is dedicated for network services including NTPD, DNS, DHCP and even DHCPv6. :) My network is IPv6 enabled and I’m running my own IPv6 prefix provided by sixxs.net. :) The HP MicroServer with 8 GB RAM is capable to run even more systems parallel. Quick trys don’t requires to turn on my home lab in my cellar. That’s very comfortable. ;) And I’m saving round about 4.000 kW/h per year. :D That’s lot’s of money. :) Thank you HP for this great server!!!
