allowing consistent visibility, control, and isolation of
applications in a multi-tenant architecture. The unique

Cisco ACE is the industry’s only fully virtualized applica-
tion delivery solution designed to meet the today’s
requirements for application delivery. ACE is a state-
of-the-art virtualized load balancer and an application
delivery solution that improves application scalability and
availability while improving the utilization of infrastructure
resources by delivering offloading and compression
technologies.

The Cisco Nexus 7000 Series offers unique virtualization
features that enable greater flexibility in network design
to fully use existing or new data center space. The
virtual devices on the Cisco Nexus 7000 Series Switch
segregate different service groups inside the same
physical Cisco Nexus 7000 Series Switch, consolidating
the aggregation layer while preserving operations and
service delivery organizational structure.

What Does Muli-Tenancy with the Cisco ACE and
Cisco Nexus 7000 Series Do?
Cisco Nexus 7000 Series Do?
Cisco multi-tenancy enables a single physical device
to be logically partitioned into many virtual devices.
Each virtual device has all the capabilities of the actual
physical device, and each virtual device is independent
and isolated so that it appears to be a unique physical
device from the viewpoint of the network and the network
administrator. With virtualization, each virtual device can
be allocated its own resources and quality of service
(QoS). Each virtual device can also be assigned its own
configuration files, management interfaces, and access-
control policies in which access control privileges are
assigned to users based on their administrative roles.

Multi-tenancy with Cisco ACE and Cisco Nexus 7000
Series enables faster rollout of applications. Adding new
application support simply requires the addition of a new
virtual partition to create a new virtual device within the
existing physical device. The virtual devices are com-
pletely isolated from each other, allowing IT administra-
tors to closely and efficiently manage system resources,
application users, and services. In addition, the strength
and security of ACE role-based access control (RBAC)
can be used to restrict individual users to see only
servers that they have rights to manage and to perform
only those ACE tasks for which they are authorized.

Data centers are evolving from a physical device model
that uses dedicated hardware to support a given applica-
tion or customer to a model that uses virtualization to
abstract the underlying data center hardware. Some of
the main customer benefits of the transition to a virtual
infrastructure include:
