How Many Hot Plug PCIe Slots Available on ML350 Gen9 Server?

The ML350 Gen9 Server offers a total of eight hot plug PCIe slots. There are four slots on the front of the chassis and four slots on the rear.

The front slots are numbered 1-4 and the rear slots are numbered 5-8. Each slot is capable of supporting a PCIe x16 card.

 Exclusive Slots & Free Spins Offers: 

The server supports up to four double-width graphics cards or eight single-width cards. For example, you could install four double-width NVIDIA Tesla K80 cards in the front slots and four single-width NVIDIA GTX 1080 cards in the rear slots.

Or you could install eight single-width AMD Radeon R9 290X cards in all eight slots.

If you need more than eight PCIe cards, you can add an optional expansion chassis. The expansion chassis has its own set of eight hot plug PCIe slots.

So you could have a total of 16 hot plug PCIe slots available (eight in the server and eight in the expansion chassis).
