In most data centers, DCIM rests on a shaky foundation of manual record keeping and scattered documentation. OpManager replaces data center documentation with a single repository for data, QRCodes for asset tracking, accurate 3D mapping of asset locations, and a configuration management database (CMDB). In this webcast, sponsored by ManageEngine, you will see how a real-world datacenter mapping stored in racktables gets imported into OpManager, which then provides a 3D visualization of where assets actually are. You'll also see how the QR Code generator helps you make the link between real assets and the monitoring world, and how the layered CMDB provides a single point of view for all your configuration data.
This webinar will help attendees understand the overall concept of SDN and its benefits, describe the different conceptual approaches to SDN, and examine the various technologies, both proprietary and open source, that are emerging. It will also help users decide whether SDN makes sense in their environment, and outline the first steps IT can take for testing SDN technologies.
Software clients are clearly the next step for WAN optimization: Most organizations have employees who don't work in a corporate office all the time, and most laptop hard drives now have enough space to spare for the large dictionaries required by data reduction. Laptop software can even lead to a greater performance boost than appliances when used with browser-based applications through SSL VPNs, as it applies reduction to unencrypted data without requiring any key sharing. However, performance takes time (and bandwidth) to ramp up, as the dictionary must be built anew for each machine: Some organizations may also be put off by the security risks of giving every laptop a large data cache that includes SSL session contents, though device theft is a problem even without this.

Citrix Systems this week introduced new client-based software to improve application performance over the WAN for mobile and branch-office workers.
Most WAN-optimization appliances do the majority of their work on the server, so mobile users in particular are often left out of the optimization equation. The new Citrix WANScaler client addresses that problem by putting optimization smarts on the local client. The software also works in conjunction with Citrix Access Gateway SSL VPN to combine secure network access with WAN optimization.
