Where the Cloud Touches Down: Simplifying Data Center Infrastructure Management

Thursday, July 25, 2013
10:00 AM PT/1:00 PM ET

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.

A Network Computing Webinar:
SDN First Steps

Thursday, August 8, 2013
11:00 AM PT / 2:00 PM ET

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.

vMotions a Killer App for 10GbE at Vonage

Every year since the first Global 2000 company installed VMware, server virtualization has been at the core of more and more data center architectures. Vonage is one major corporation that is now making the leap, and its architects shared with me how 10 Gigabit Ethernet is playing a key role in how the organization handles vMotions.

With approximately 2.4 million subscribers, Vonage maintains and operates a VoIP network that supports more than 6 billion communications per year to more than 60 countries. Located at corporate headquarters in Holmdel, N.J., is the Vonage Development and QA Lab. It’s here that new technology and products are evaluated before they can enter a production environment. The lab also is where the company's IT architects and engineers develop and certify the standard hardware and software images that will be used in production systems ranging from front-end Web servers to back-end database servers.

Taking advantage of technologies that will allow the company to consolidate infrastructure, reduce costs and speed new server deployments, the Holmdel data center is migrating from a mostly non-virtualized, "discrete" environment to a virtualized data center. This installation features about 40 data center cabinets with 1,100 rack-mount servers, each dedicated to specific applications. The power-hungry rack servers are connected to data center LANs and SANs by more than 3,000 cables, and deploying a new server takes about two weeks from the time a user makes a request.

The migration from discrete data center to virtualized data center involves many new technologies, products and processes. Blade servers, server virtualization and network virtualization stand out as technologies that are key to slashing costs while maintaining application performance and availability.

--Blade servers: Vonage is deploying HP ProLiant BL490c G7 blade servers to perform the same function as rack servers but with far less floor space, power, cooling and cables. By sharing resources through a single enclosure, blade servers will also eliminate a great deal of management complexity and overlap.

--Server virtualization: A typical application server utilizes only 1% to 5% of available CPU. Server virtualization allows Vonage to fully utilize the compute power of each physical blade server by running multiple virtual machines (VMs) and applications. The result is another level of massive consolidation and cost savings.

--Network virtualization: To accommodate the proliferation of VMs, the HP BladeSystems feature virtual networking capabilities that allow server admins to configure unique virtual networks for each VM. Embedded on G7 servers used by Vonage are dual-port integrated HP Virtual Connect 10-Gbit FlexFabric Adapters, which are based on Emulex OneConnect technology. A single HP 10-Gbit FlexFabric Adapter port can be configured as four FlexNICs, with an option to configure one as a FlexHBA for either Fibre Channel or iSCSI storage connectivity. Each FlexNIC or FlexHBA can be configured with its own set of network policies tailored to the needs of specific VMs and applications.

Once Vonage architects got started, they realized the bar was set high. The 1,100 rack servers that form the company's discrete production environment are highly tuned for maximum performance and availability. The rest of the IT team was skeptical that a mass migration to virtual servers could be accomplished without compromising one or both. Therefore, the first step was to pilot the technology with a single blade system chassis and two server blades.
