Network energy efficiency starts in the LAN closet
Many look to data center servers and storage to cut power use, but network energy efficiency can start inside the LAN closet with switches, routers and security devices.
-
Addressing virtualization security challenges
The network plays a role in addressing virtualization security challenges, but typical firewalls are not necessarily part of the solution.
-
Protecting virtual environments with DMZ networks
Connecting virtualized environments to DMZ network architecture creates new challenges. Network managers must learn new design methodologies to protect virtual traffic in the DMZ.
