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.

VMware's Casado: Network Virtualization The Right Way

The true benefits from network virtualization will come from simplifying the network and applying it to broader use cases, rather than bickering about the finer points of vendors' SDN products, according to VMware's Martin Casado.

Data Center Interconnects: An Overview

It's common for organizations of a certain size to have two data centers as part of a disaster recovery or business continuity plan. A data center interconnect extends an Ethernet network between two physically separate data centers. While the idea is simple, Ethernet wasn't designed to run across a WAN. Thus, a DCI implementation requires a variety of technological fixes to work around Ethernet's limitations. This report outlines the issues that complicate DCIs, and examines the variety of options companies have to connect two or more data centers, -including dark fiber, MPLS services and MLAG, as well as vendor-specific options such as Cisco OTV and HP EVI.

Is Hosted VoIP Right for You? 6 Must-Ask Questions

We outline six questions you must ask when deciding whether to move your telephony system to a hosted VoIP provider, including questions about reliability, branch survivability, E911 capability and whether you�re looking for additional collaboration services. We also outline how to price a hosted VoIP option.

Understanding Flat Networks

A flat network or fabric provides more paths through the network and can maximize bandwidth and better support a highly virtualized data center. We'll look at standards-based approaches to designing a flat network, including TRILL and SPB, as well as proprietary implementations. We'll also discuss the implications of moving to a flat network and provide guidance to help you decide if this approach is right for your data center.

3 Paths To Network Convergence

Separate data and storage networks might have been necessary when Fast Ethernet was pitted against speedy, special-purpose Fibre Channel, but Ethernet's evolution has obviated most of the performance differences. We'll examine the trends behind network convergence, share exclusive research, and outline three deployment scenarios for those who want to merge data and storage networks.

Networking In A Virtualized World

Virtualization is rapidly evolving into a core element of next-generation data centers. This expanded role places new strains on the network. This report explore the technical issues exposed by virtualized infrastructure and looks at standards, technologies and best practices that can make your network ready to support virtualization.
