Cisco Cisco Catalyst Blade Switch 3020 for HP 数据表

For HP c-Class BladeSystem customers, the Cisco

®

Catalyst

®

Blade

Switch 3020 is an integrated switch that extends Cisco infrastructure
services to the server edge and uses existing network investments
to help reduce operational expenses.

• 16 internal 1000BASE ports connected to servers

through the c-Class BladeSystem backplane.

• Up to 8 external Gigabit Ethernet uplink ports.

• 4 external dual-media Ethernet interfaces. Interfaces can be

either 1000BASE-SX SFP or 10/100/1000BASE-T ports. The
Small Form-Factor Pluggable (SFP) cage supports Gigabit
Ethernet Fiber SX SFP modules from Cisco Systems

.

• 4 additional external 10/100/1000BASE-T ports. Two of these

ports can be configured to provide an internal crossover 
connection to an associated additional Cisco Catalyst Blade
Switch 3020.

• 1 Fast Ethernet connection to the HP enclosure onboard

administrator.

• 1 external console port.

• Maintaining the highest availability to meet increasingly 

stringent service-level agreements

• Securing network assets to protect against information theft

• Scaling quickly to adapt to rapidly changing business 

environments

• Enhancing operational efficiency through a common 

management framework and delivery optimization features

• Decreases cable complexity by up to 90 percent and completely

eliminates the required cabling between servers and the integrated
switch.

• Reduces space requirements by providing an integrated 

switch in a chassis that can be more densely populated 
than the traditional server rack.

• Improves manageability to the server edge by using an 

end-to-end Cisco management framework, CiscoWorks, 
and embedded Web-based GUI tools.

• Secures assets by integrating Cisco IOS

®

Software security

features.

• Enhances operational efficiencies by providing a platform 

to integrate common network services to the server edge.

Designed for the HP c-Class BladeSystem Enclosure, the 
Cisco Catalyst Blade Switch 3020 helps ensure consistency across
the network for advanced services such as security and resiliency. 
It also allows customers to use the end-to-end Cisco management
framework to simplify ongoing operations.

Available with a Cisco IOS Software LAN base image, the Cisco
Catalyst Blade Switch 3020 provides network security features such
as extended access control lists (ACLs) and quality-of-service (QoS)
traffic policers to help mitigate flooding and attacks. The switch is
also Network Admission Control (NAC) compliant. NAC allows for
effective admission control, posture validation, and virus detection
at the network level, before serious damage can reach servers or end
stations.

The Cisco Catalyst Blade Switch 3020 also incorporates many
resiliency features such as FlexLink and trunk failover to create 
a highly available integrated switch. FlexLink can coexist with spanning
tree and allows convergence time of less than 50 milliseconds on
switch uplink ports, providing extremely rapid spanning tree recovery
intervals. Trunk failover allows rapid failover to the redundant switch
in the blade enclosure if all uplinks from the primary switch fail,
allowing uninterrupted network performance.

The Catalyst Blade Switch 3020 comes with an embedded GUI
device manager that simplifies initial configuration of the switch.
Also, support for CiscoWorks management software means that 
the Cisco Catalyst Blade Switch 3020 is the right fit for enterprise
and data center customers. CiscoWorks offers automated inventory
collection, software deployment, easy tracking of network changes,
views into device availability, and quick isolation of error conditions.

The Cisco Catalyst Blade Switch 3020 for HP c-Class BladeSystem
enclosures is an excellent choice for data center and enterprise 
customers needing to deploy a secure, resilient, and highly 
manageable blade switch solution.

The Cisco Catalyst Blade Switch 3020 offers superior multilayer,
granular QoS features to avoid congestion and help ensure that
network traffic is properly classified and prioritized. The Cisco
Catalyst Blade Switch 3020 can classify, police, mark, queue, and
schedule incoming packets and can queue and schedule packets 
at egress. Packet classification allows the network elements to 
discriminate between various traffic flows and to enforce 
policies based on Layer 2 and Layer 3 QoS fields.
