Cisco Cisco Catalyst Blade Switch 3120 for HP White Paper
Design Guide
Figure 7 depicts a service switch deployment. The aggregation switches for each data center
modules are Layer 3 attached to the core. In addition, the aggregation switches house the service
modules required to support the server farms. The aggregation layer provides the connectivity layer
for the various access layer switches. In a typical Data Center network, this layer will have
connections from Blade and non-Blade switches, providing connectivity for all the servers in the

Data Center Scaling with Service Switches
The data center core is a mechanism to replicate and horizontally scale the data center
environment. In the recommended design the aggregation and access layers are regarded as a
module that can be duplicated to extend the enterprise. Each data center module provides its own
network services locally in the aggregation switches. This approach allows the network
administrator to determine the limits of each data center module and replicate as necessary.

Management
The Cisco Catalyst Blade Switch 3120 is accessible for management and configuration by any of
the following traffic paths:
the following traffic paths:
●
Out-of-band management
●
In-band management
●
Serial console port
These traffic paths provide three different management options for network administration and
support different user and application interfaces to the Cisco Catalyst Blade Switch 3120. The
remote management of the blade servers within the blade enclosure is critical to an efficient and
scalable data center. The various Blade Server vendors offer connectivity options provided using
the enclosure to the blade servers are also discussed. See the particular Appendix for your
enclosure type.
