NVGRE standard means more VLANs in the cloud
Microsoft's NVGRE standard offers competition to VMware's VXLAN standard, promising to create more VLANs that stretch across Layers 2 and 3 for multi-tenant cloud networks.
-
Storage virtualization benefits and challenges
Storage virtualization benefits abound, but along with the ability to implement dynamic storage provisioning for the cloud come some complications…including latency.
-
VXLAN extends VLANs for long-distance VM mobility
The VXLAN standard aims to solve the long-distance VM migration dilemma by enabling extended VLANs across geographically dispersed data centers for a multi-tenant cloud network.

Facilities management on your network: Security issues
Linking building and power management systems to converged Ethernet networks brings new security concerns.
-
vSwitch architecture best practices
vSwitch architecture varies depending on the type of traffic being managed and how many physical NICs are connected. Learn these best practices.
-
vSphere vSwitch primer: Design considerations
It takes the right kind of vSphere vSwitch design to implement segmentation for traffic manageability, security, redundancy and failover in a virtual environment.
-
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.
-
Connecting virtual hosts to the DMZ: Best practices
DMZ networks can be used to protect virtualization hosts, but best practices must be considered, including combing virtual and physical firewalls and locking down virtual switches.
-
Mobile Wi-Fi hotspots for the enterprise
Businesses have taken notice of the mobile Wi-Fi hotspots trend and have invested in mobile hotspot devices. Question is, which of several options is most suitable for business?
-
Integrating IT and IP-based building management systems
As IP-based building management systems emerge, networking teams will control integrated IT and building resources as part of an overall enterprise energy management strategy.
-
Does a virtualization networking solution exist?
In a perfect world, virtualization networking would mean non-blocked, any-to-any access between nodes on the network, but that doesn't really exist yet. So what's the alternative?
-
Troubleshooting network routing issues
Expert Patrick Hubbard shares how you can make your life easier by alleviating some annoying network routing issues.
