Quick notes on setting up 4 Raspberry Pi’s for a media wall using the PiWall info from and the built in tile codes.   Keep in mind that the raspberry pi’s need the network hard wired.  I initially tried doing this with WiFi and the displays are so pixelated they are not watchable.   […]

So, until now, on long trips, I had setup a small netbook running Ubuntu with a DLNA media server, with external HD attached with the media files.  And a WiFi router to provide the wireless network so my kids could watch videos on their tablets.  Not only was this setup big and bulky, but it […]

This is the process to add a new Unifi AP to the Unifi controller when discovery doesn’t work.  In our case, we have a central Unifi controller managing APs on multiple networks.  But, the routers don’t allow the discovery tool to see new APs on other networks, so this is how we add one.  In […]

Read/Write HDD Speed Test

Posted October 22, 2014 By admin

These are the observations I recorded while doing some read/write speed tests on a server.  The main goal was to see the performance difference between RAID1, RAID5, and RAID10.  I also tossed in another RAID5 test with more drives.   The tests were performed with a PERC5 controller using 3 to 5 15K RPM SAS […]
