Q: My host is running ESXi 6.7. Is it compatible? How many SATA ports are supported?**

A:  Yes, ESXi 6.7 recognizes it normally and supports pass-through without needing drivers. It supports 5 SATA ports.

Q: Is it compatible for building a NAS + Soft Router on the ESXi platform?**

A: It is fully compatible. It is driver-free and easy to use. The BIOS can directly recognize the connected hard drives. For NAS, it can expand up to 5 SATA ports at once.

Q: Hi, after inserting the card, ESXi fails to enter the backend. Removing the card allows it to boot normally. Why is that? Do I need to install additional drivers in Linux?**

A: Linux supports driver-free operation.  

Check if the system has enabled the setting to skip ACS (Access Control Services) checks for all PCI devices and set it to true.  

Change the slot.  

Check if the PCIe address of the network card is occupied.

Q: Why can't the hard drive be detected, and why does it show a yellow exclamation mark after installing the driver?

A:

1. Uninstall the existing device and driver, then re-download and install the driver, followed by a reboot.

2. Change the slot and use an eraser to clean the card's gold fingers.
