Cisco Server Virtualization with Red Hat

Install Linux on Cisco UCS

View detailed instructions about installing Red Hat with Cisco UCS to virtualize your servers.

For consolidated environments to be effective, virtualization must deliver scalable application performance, security, management efficiencies, and cost-savings. Through its open source lineage, Red Hat Enterprise Virtualization (RHEV) inherits the performance, scalability, and robustness of Linux -- supporting large memories and numerous virtual CPUs for each virtual machine.

Along with these benefits, organizations improve network performance through Cisco VN-Link technology. They also get security benefits from SELinux security technology, as well as from Cisco VN-Link technology's ability to view and control connectivity down to the virtual machine level.

Using Cisco service profiles, each organization can deploy an infrastructure much more quickly, eliminating time-consuming and error-prone manual provisioning tasks. This unique combination of technologies helps you:

  • Overcome limitations of traditional virtualized environments
  • Improve total cost of ownership (TCO)
  • Obtain a faster return on investment (ROI)
  • Gain an effective, scalable, and secure infrastructure

Reduce Costs and Improve Efficiencies

Cisco infrastructure simplification and Red Hat's cost-effective subscription models combine to reduce short-term and long-term costs for delivering virtualized solutions. In addition, organizations can use Cisco innovation backed by the open source community -- resulting in an open, integrated, and tuned environment for virtual infrastructure deployment.

Gain Hardware-Accelerated Virtual I/O

Cisco VN-Link technology, in tandem with Red Hat Enterprise Virtualization (RHEV) server virtualization technology, provides hardware-accelerated virtualized I/O benefits to open-source products. These benefits include:

  • Higher visibility and network control
  • Improved network performance
  • The ability to manage the virtual network infrastructure while managing your physical infrastructure

Server Virtualization with Red Hat integrates Cisco-VN link into the RHEV virtual server environment. Cisco Virtual Network Link (VN-Link) provides a set of features and capabilities to individually identify, configure, monitor, migrate, and diagnose virtual machine interfaces in a way that is consistent with current network operation models for physical servers.

To deliver VN-Link technology, support for the Cisco UCS M81KR Virtual Interface Card is integrated into the open-source, kernel-based Virtual Machine (KVM) hypervisor provided with RHEV. Combined with Red Hat support of Linux I/O virtualiza¬tion, this solution delivers multiple 10 Gigabit Ethernet network interface cards (NICs) to virtual machines, which:

  • Improves network throughput
  • Frees CPU cycles to deliver greater application performance
  • Enhances virtual machine density

These benefits are amplified by the intelligent performance of Intel® Xeon® processors, which can increase processor frequency when more application performance is needed.
