Abstract: Virtualized Application Delivery with Cisco Application Control Engine (ACE) By Cisco Systems

Deployed as a service module in the Cisco Catalyst 6500 Series Switches for ease of deployment and use, the Cisco ACE delivers superior performance, scalability, high-availability, application acceleration, and data center firewalling capabilities. Cisco ACE simplifies the application infrastructure by offering a single point of policy control in the network with the industry's only virtualized architecture.

The Cisco ACE solution provides the following benefits:

- Application rollout velocity: Reduces time required to deploy and upgrade crucial applications

- Data center cost reduction: Reduces costs and resource requirements associated with data center application infrastructure

- Application performance: Provides the industry-leading performance, scalability, and availability for data center application delivery

- Application infrastructure control: Gives IT organizations a next-generation solution to better control the way they deploy, operate, and manage data center application infrastructure with virtual partitioning and RBAC

- Data center firewalling: Helps ensure that crucial applications, infrastructure, and data are protected from abuse and misuse

- Network simplification: Minimizes the cost and complexity of the network and reduces the number of devices and vendors required

The unique virtualization capabilities of Cisco ACE enable the support of numerous applications and departments in multiple isolated virtual devices on a single Cisco ACE module, resulting in optimized capacity utilization, decreased deployment costs, improved workflow, and decreased power consumption costs.

It is important to note that the Cisco virtualization implementation is at the device-level, allowing all aspects of the physical device to be virtualized. Other vendors limit their support of virtualization to access-control capabilities and do not offer device-level virtualization equivalent to that offered by Cisco ACE.

Abstract: Network Implications of Server Virtualization in the Data Center By Cisco Systems

Virtual machine environments place unique demands on network infrastructure. Although virtual machines can simplify the physical server infrastructure, they can add complexity to the LAN and SAN fabrics within the data center. The effect on the LAN and SAN in terms of resources consumed is amplified because each virtual machine is identified by a unique MAC, IP, and WWN address.

Cisco Catalyst switches support functions that delivers predictable application performance, security, and availability for dense virtual machine environments, as well as tools that simplify management and operation of the virtual machine environment.

In the SAN environment, the Cisco MDS 9000 family provides technologies such as VSANs and IVR to enable integration of the SAN fabric and virtual machine environments in a way that preserves the functional objectives of the virtual machine strategy while maintaining the segmentation necessary for proper information security and regulatory compliance.
