HP Flex-10 and SR-IOV—What is the difference?
Improving I/O performance
As virtual machine software enables higher efficiencies in CPU use, these same efficiency enablers place more overhead on
physical assets. HP Flex-10 Technology and Single Root I/O Virtualization (SR-IOV) both share the goal of improving I/O
efficiency without increasing the overhead burden on CPUs and network hardware. Flex-10 and SR-IOV technologies
accomplish this goal through different approaches. This article explores the differences in architecture and implementation
between Flex-10 and SR-IOV.
How these two technologies differ and why it matters
HP Flex-10 Technology
Flex-10 technology is a hardware-based solution that enables users to partition a 10 gigabit Ethernet (10GbE) connection and
regulate the bandwidth of each partition. HP Flex-10 is available only with Virtual Connect (VC), and is currently available for
implementation only with supported HP BladeSystem servers.
Flex-10 can be deployed now with HP BladeSystem servers, and with relatively little modification to existing I/O architecture.
Adding Flex-10-capable network devices and virtual connect modules to existing HP BladeSystem infrastructure allows
administrators to take advantage of the considerable I/O control and refinement delivered by Flex-10 technology.
Using Flex-10 technology, administrators can configure a single BladeSystem 10Gb network port to represent four physical
network interface controllers (NICs), also called FlexNICs, with a total bandwidth of 10Gbps. These four FlexNICs appear to
the operating system (OS) as discrete NICs, each with its own driver. While the FlexNICs share the same physical port, traffic
flow for each one is isolated with its own MAC address and virtual local area network (VLAN) tags between the FlexNIC and
