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.

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.

Panasas Leads Charge to Parallel NFS

Panasas is so obsessed with an emerging standard for managing NFS file access that it will launch free client source-code this summer. (See Panasas Accelerates pNFS Adoption.)

The question is, Who'll glom on?

The standard is Parallel NFS (pNFS), an extension of the next release of NFS (Network File System), which is working its way through the IETF approval process. As an adjunct to the upcoming NFS 4.1, pNFS describes a way for the NFS protocol to process file requests to multiple servers or storage devices at once, instead of handling the requests serially.

"You could say NFS was invented by Bill Joy at Sun back in 1983, and the thing hasn't had a major performance upgrade in two decades," says Panasas VP of marketing Larry Jones. The I/O processing involved in retrieving stored NFS files is still mostly serial, he notes. It's time to bust the bottleneck by making it parallel.

Clustered file systems are growing in popularity, but not all of them have parallel I/O for NFS (though some claim performance improvements via their own file systems). Panasas's claimed differentiator has been a clustered storage client called DirectFlow that deploys parallel I/O for NFS.
