# Enable the SR-IOV

Many hardware vendors ship their products with the SR-IOV feature disabled. The feature must be enabled on such platforms before installing the Weka system. Enabling the SR-IOV applies to the server BIOS.

If the SR-IOV is already enabled, it is recommended to verify the current state before proceeding with the installation of the Weka system.

## Before you begin

Verify that the NIC drivers are installed and loaded successfully. If it still needs to be done, perform the [Install NIC drivers](https://docs.weka.io/4.2/install/bare-metal/setting-up-the-hosts/..#install-nic-drivers) procedure.

## Enable SR-IOV in the server BIOS

The following procedure is a vendor-specific example and is provided as a courtesy. Depending on the vendor, the same settings may appear differently or be located elsewhere. Therefore, refer to your hardware platform and NIC vendor documentation for the latest information and updates.
