This video is the second in a series of 3 videos where I will show you how you can upgrade the storage subsystem of the Dell PowerEdge R820. And, since the R820 shares the chassis with the R720, this upgrade will also work with the PowerEdge R720. In this second part, I will take our upgrade path to the next level with SAS-3 hardware in the R820 and R720 that originally only came with SAS-2 hardware, by taking advantage of the direct attached backplanes. We will install a SAS-3 HBA card, new SAS cables, and HGST SAS-3 SSDs. I will also re-run the same benchmarks I ran with the previous SAS-2 setup for comparison to show you what performance benefits can be gained with this SAS-3 upgrade.
