2 out of 5 eggs2TB Max Drives

Pros: Seems like it would work with ESXi. MegaRaid SMS software will run in VM and allow management of ESXi host adapter.

Cons: This is an old card that does not support modern equipment. The WebBios software (used to set up manage RAID before the operating system boots) has very sketchy compatibility with UEFI. I could not get it to work. I was finally able to get this up and running using a VM (see pro above) only to find out that only 2TB of each 4TB drives was visible. Disappointed. I don't see anything in the product description regarding a drive-size limitation.
