Intel I340 Ethernet Dual Port and Quad Port Server Adapters for IBM System x

Virtual Machine Device Queues (VMDq) reduces I/O impact on the Hypervisor in a virtualized server by
performing data sorting and coalescing in the network silicon. VMDq technology makes use of multiple
queues in the network controller. As data packets enter the network adapter, they are sorted, and packets
traveling to the same destination (or virtual machine) are grouped together in a single queue. The packets
are then sent to the Hypervisor, which directs them to their respective virtual machines. Relieving the
Hypervisor of packet filtering and sorting improves overall CPU usage and throughput levels.

The adapters have complete iSCSI support for proven native OS and VMM iSCSI initiators as well as
iSCSI boot. Historically, CRC32C computation has degraded system performance, but now with the CRC
instruction set included in the latest Intel Xeon processors, CRC validation is possible with minimal
impact to network throughput while delivering data integrity.
