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.

VMware Does Complicated Dance With Open Source

November 09, 2012

When it comes to thinking about the future data center, it's well understood that servers and storage will function as pools of virtualized resources that can automatically switch from task to task. Networking is a much harder nut to crack. It remains unvirtualized and has lagged far behind the other two. But without it, we'll never get to the flexible, automated data center of the future envisioned as a "private cloud." That's why I sat down to talk to Martin Casado, the former Stanford grad student whose PhD thesis turned into the OpenFlow networking protocol. Casado co-founded virtual networking firm Nicira, which soon became the lead contributor to OpenStack's virtual networking project, Quantum. VMware bought Nicira for $1.26 billion in July -- not bad for a young company with 100 employees. I'd asked Casado to explain how Nicira was going to continue to lead development of virtual networking in OpenStack, since open source OpenStack competes directly with VMware to manage the virtualized part of the data center that's implementing automated self provisioning, elastic expansion and chargeback -- the private cloud part.

Dell Switch Supports VMware NSX

S6000 connects physical and virtual infrastructures; Citrix NetScaler works with NSX; Gigamon adds multi-tenant traffic visibility; Check Point updates software blade architecture.

A Plug For Plugfests

August 15, 2013

Standards are great, but there can be significant differences in vendor implementations. The University of New Hampshire's InterOperability Lab provides a neutral venue for testing and analysis.

Intel's Data Center Plan: More Than Chips

July 26, 2013

The chip giant aims to shape future data center designs for everything from rack-level systems to software defined networks and servers.

SDN's Next Steps: Product Integration

July 01, 2013

SDN interoperability demonstrations and hackfests point to a small but growing movement toward product integration as software defined networking evolves.

VMware Adds Interoperability With Ubuntu OpenStack Cloud

April 19, 2013

VMware has contributed plug-ins to the OpenStack Project that guarantees the project's networking platform will recognize and work with virtual machines running under VMware's vSphere management environment and VMware's Nicira Network Virtualization Platform.

VMware acquired startup Nicira last July for $1.26 billion and has made its NVP the basis of future virtualized networking in what it terms "the software-defined data center." The Network Virtualization Platform from Nicira, a leader in OpenFlow network protocol concepts, is also the basis for the Quantum networking platform in OpenStack. Nicira was a heavy contributor to OpenStack before the acquisition, and it remains one now. At the OpenStack Summit on Tuesday, VMware gave these contributions a particular cast. Through close collaboration between Canonical and VMware, they will work inside the Ubuntu distribution of OpenStack, according to VMware's VP of vSphere product management Joshua Goodman.

Suse Linux and Red Hat also have distributions of OpenStack. Red Hat's KVM hypervisor is the one native to the OpenStack cloud open source code. Suse Linux is often cited as the version that works most closely with Windows Server and its hypervisor, Hyper-V. Both are keen competitors of VMware's ESX Server.

The move also reflects VMware's growing realization that it is likely to need to live with many OpenStack implementations in the future, despite its early hopes that its own cloud software stack, the vCloud Director suite, would be the basis of private and public clouds everywhere. The collaboration with Canonical gives it an OpenStack partner that is less an immediate competitor than either Red Hat or Suse.

Software Defined Data Center: Marketing or Meaty?

July 19, 2013

The software-defined data center is the latest term being applied to the abstraction, orchestration and automation of hardware-based resources via layers of code. Is it just empty marketing, or is there something you can sink your teeth into?

Big Switch Leaves OpenDaylight, Touts White-Box Future

June 06, 2013

Big Switch is stepping away from the OpenDaylight project, which is building an open-source controller. As it departs, the company says the market clamors for white-box SDN switches. Is that right?

Avaya SPB Fabric Put to the Test at Interop

June 03, 2013

Data center fabrics have been overshadowed by SDN, but vendors are still moving forward with fabrics. This year's Interop was a big, visible test for Avaya's implementation of the Shortest Path Bridging (SPB) standard.
