To find out the Controller your T140 is equiped with just take a look windows device manager, OMSA or just visit dell.com/support and enter YOUR service tag(STAG) and on the middle right it will show how the server left the factory. If you "only" have the software based controller it should be S140 or the hardware one which named Hxxx. I have not checked if BOSS is supported for your T140(in 15 years as a dell partner i never touched a 1xx poweredge IIRC ). The BOSS exists as FullProfile and HalfProfile so check if you have a free PCIe Slot available and if its a LP or FP one. I expect that T140 only have FP. Yes, the BOSS-S1 is supportet from every modern OS and we have running Windows Server, vSphere ESXi and also Linux from it. If you buy one please aware that there are 2 SKUs needed. One for the PCIe Board and another one for the M.2 SSDs. If you wanna have a RAID 1 you need the SSD SKU two times.

I have a PowerEdge T140 which currently has an HDD installed. The HDD is a bottleneck and I would like to replace it with an SSD. The Dell support only presented one option (Dell 240GB SSD M.2 SATA 6Gbps Drive - BOSS) which has far to little storage for my purposes. My question is therefore; would an SSD be compatible with the PowerEdge T140, as long as it is of the M.2 form factor? Or is there something else one should also check before assuming compatibility? I notice for example that the M.2 SSD presented by Dell has a different pins setup than that of a competitor. Any guidance here would be appreciated.
