1 NIC Intel 82599 10 Virtual NIC E1000 Gigabit (SR-IOV) (Xen PV NIC model) Intel 82576 1 Igbvf Gigabit (SR-IOV) (Intel 82576/82599 VF) Sender/Receiver Intel i7 CPU/Intel 82599 10G NIC, Intel 82576 1G NIC Table 2.
The MAC address of the virtual NIC in the VM and an interrupt destination processor can be assigned to each hardware receive queue.
In addition, SMC's virtual NIC support (VNIC) provides a clean and efficient way to maximise network and CPU efficiency in virtualised operating system deployments.
IBM and Emulex co-developed the VFA technology for BladeCenter, and each of these cards is able to support exclusive virtual NIC (vNIC) functionality that optimizes network performance, scalability and flexibility for virtualized servers when combined with IBM's switching modules.
In this solution, instead of a hypervisor virtualizing an I/O device in the software and sharing that emulated virtual NIC with multiple VMs, a single I/O hardware itself is subdivided logically to appear as 128 virtual NICs.
License upgrades can further enhance adapter functionality with Fibre Channel over Ethernet (FCoE), delivering a future proof connectivity solution for IBM BladeCenter that enables multiple virtual NIC and FCoE ports on the same adapter.
Data synchronization was performed on wide-area Infiniband via an iSCSI connection on a virtual NIC (Network Interface Connection) by using Xsigo Systems virtual I/O technology.
This I/O consolidation and scale out, which results in significant cost and power savings, is achieved transparently as operating systems and applications running in the virtual machines continue to run over traditional virtual NIC and HBA interfaces available in VMware virtual machines.
5% reduction in network devices; 17 times more VMs per hardware device; 66% less cabling; real time performance monitoring of virtual NICs and virtual HBAs; as well as improved power consumption and uptime.
lt;p>Crossbow not only provides technologies like Virtual NICs (VNICs) and Virtual Switches for isolating applications on virtual machines (VM), but includes resource management and flow controls to provide such features as bandwidth management and quality of service for separate VMs.
With up to 4 virtual NICs per port, MPF delivers flexible allocation of bandwidth and eliminates the need to dedicate a real NIC for each traffic type.
Xsigo virtual I/O eliminates numerous cards and cables associated with server I/O, replacing them with a wire-once infrastructure and virtual NICs and HBAs that allow redundant connections to be configured on-the-fly, without server downtime, the company said.
