-The Single Root I/O Virtualization (SR-IOV) specification is a standard for a type of PCI device assignment that can share a single device with multiple pods.
+[role="_abstract"]
+To share a single physical device with multiple pods, implement the Single Root I/O Virtualization (SR-IOV) specification. This standard enables flexible PCI device assignment, allowing a device to show as multiple separate physical devices for efficient resource allocation.
+
+[NOTE]
+====
+As of {product-title} 4.21, the SR-IOV Operator can support ARM hardware.

 You can configure a Single Root I/O Virtualization (SR-IOV) device in your cluster by using the xref:../../networking/networking_operators/sr-iov-operator/installing-sriov-operator.adoc#installing-sriov-operator[SR-IOV Operator].
