How to drive 120 HDDs with a single 2-port HBA IT mode SAS controller

In this video, I'm going to show you a setup with one LSI 9240-8i HBA card and 7 SAS expanders (IBM SAS2 46M0997) that can drive 120 HDDs! This came about because some people had asked the question of whether or not SAS expanders can be daisy chained and the answer is yes. Although the setup in this video isn't something I would normally recommend, due to the bottleneck and potential for catastrophic disk disconnects, it is a possibility to do this and perhaps might suit some very specific scenarios.

Products mentioned in this video that I sell:

Lenovo 9240-8i - http://ebay.to/3evjMRW
IBM SAS2 Expander - http://ebay.to/3viIFWL
or, as an alternative to the IBM, the Lenovo 03X3834: http://ebay.to/2OMoLTg

If you'd like to buy a pre-flashed ready-to-go LSI IT mode SAS HBA card from me, checkout my eBay store: https://ebay.to/3l4xlch
