Cisco blade switches provide an easy, smart, and flexible blade server I/O solution that allows customers to reap the
full benefits offered by the blade server architecture:
●
Easy: Easy to operate and deploy
◦
Because there are fewer switches to manage with VBS technology, helps solve the problem of switch
sprawl
◦
Provides consistent management interface and tools throughout the Cisco data center and blade switch
portfolio, accelerating service provisioning and simplifying troubleshooting
◦
Through VBS technology, provides operational transparency and efficiency during replacement and
addition of switches
●
Smart: Feature-rich, “server-smart” networking solution
◦
Provides highly resilient LAN uplinks to increase blade server and virtual machine availability using
innovations such as trunk failover and EtherChannel
◦
Helps secure application servers and virtual machines using private VLANs and access control lists (ACLs)
◦
Provides intelligent congestion management mechanisms to optimize network bandwidth using quality of
service (QoS)
◦
Provides advanced Layer 2 and 3, IPv4 and IPv6, and multicast capabilities to facilitate smart end-to-end
server networking in the data center
●
Flexible: Flexible solution to scale resources and facilitate data center virtualization
◦
Through VBS, provides flexibility to configure network topology based on application needs such as
performance, scalability, and resiliency
◦
Through VBS, provides investment protection and a flexible transition path with the capability to mix and
match Gigabit Ethernet and 10 Gigabit Ethernet switches
◦
Provides flexible options for configuration and management such as a command-line interface (CLI) and a
GUI
