How to extend 1U / 2U servers with multiple 2 slot full height GPUs for sharing? [closed]

What are the possible options to extend a 1U / 2U server with a GPU?

e.g. I am searching for a solution how to add a GTX 1650 into the server. The GPU is usually 2 slots width and therefore often not fitting into a 1U/2U server

for what usage?

• i want to do a directIO passthrough to a virtualized OS to have a "native" access to a GPU. E.g. for video or GPU intensive renderings (blender, Davinci and so on)

Already tried the x1 adapters to simulate a external x16 slot, which are typically used for mining, but the performance was a big issue

are there any standards to switch to?

any suggestions for a solution for shared GPUs?

Many 1U and 2U cases servers mount full-size PCIe cards horizontally using a PCIe riser card. Find a server with a case that has enough room for your card.

This is a feature that you must choose when you select a server.

For example this 1U server (which might be be a SYS110P-WTR) can mount two full-size PCIe cards (or one double width card) and one low-profile card (on the back of the riser)

Servers with preinstalled GPUs are also available.
