Recovering the Firmware on a Supermicro BPN-SAS3-846EL1 Backplane

I suspect the LSI card does not play nice with the SGPIO sideband controller, and I decided to replace the chassis with one similar to my SC846 chassis, where the LSI card and […]

In this post I detail the results of my testing of the Western Digital RE4-GP enterprise class “green” drives when used with hardware RAID controllers from Adaptec, Areca, and LSI. To summarize, the RE4-GP drive […]
