Are Grid Computing & Virtualization Blending?

March 21, 2006 by Robin Wauters Leave a Comment

The synergy between Grid computing and virtualization is becoming more and more apparent and is starting to find common ground in Linux.

At Novell’s Brainshare conference, virtualization is taking the spot light.  In fact, Dell made an announcement that it will offer Novell ZENworks for Linux servers.

Adam Fineberg’s (Levanta) view was reported by InfoWorld

Adam Fineberg (Vice President of Engineering at Levanta) sees specific technical reasons why Linux has become the most widely used OS for Grid environments:”Some of the key aspects of an operating system that you really need take advantage of in a Grid computing environment are the networking and file systems. The networking side is very important because of the large number of nodes, the need to quickly / easily add more nodes, exchange information between the nodes with low latency, as well as access shared storage systems and devices. Linux does very good ‘zero copy’ networking, meaning that once the data reaches the network stack, it doesn’t have to be copied again all the way through the rest of the operating system. That really keeps the networking efficient in Linux systems. With respect to file systems — because of the very strong interface that’s defined within Linux, there are a great number of file systems that are available for you. And that’s something that’s fairly unique to the Linux OS. Most of the operating systems don’t actually have a large number of file systems available for them, other than some standard ones like NFS. That makes it relatively easy to pick a file system that’s well-suited for your particular application. So having access to, for instance, XFS or JFS — which are two very high performance file systems that have good characteristics, but by the same token have very different implementations and therefore very different operating characteristics — you can optimize by choosing the file system that’s best suited for your application.”

The embracing of Linux by the Grid / Virtualization community boils down to being able to understand the boundary values of this set of complex use-case equations. Linux, being open source, lets you get at the raw OS kernel code. This gives you access to the “boundaries” of the OS, the way it interfaces to applications and the hardware. An intimate understanding of these boundary conditions are critical to Grid and Virtualization…

Novell Announces Support for Xen 3.0 in SUSE Linux Enterprise v10

March 20, 2006 by Robin Wauters Leave a Comment

Press Release from Novell at BrainShare® 2006

SUSE Linux Enterprise 10 delivers new features for mission-critical operations, including Xen virtualization, improved performance and the industry’s easiest-to-use application security

SALT LAKE CITY —20 Mar 2006—Novell today introduced its next-generation platform for the open enterprise, SUSE® Linux Enterprise 10. Novell’s SUSE Linux Enterprise is a secure and reliable foundation for enterprise computing from the desktop to the data center. It will be first to deliver fully supported Linux* innovations such as Xen virtualization, exceptional performance and scalability, application-level security, and improved desktop usability. As a result, organizations will be able to experience the flexibility, power and reliability of the best-engineered Linux, backed by Novell’s industry-leading support, services and training.

“Novell has a broad vision for open enterprise computing, and no other Linux vendor has a comparable lineup of enterprise-class solutions that address the pressing needs of today’s IT executives,” said Jack Messman, chairman and CEO of Novell. “SUSE Linux Enterprise is the platform for the open enterprise. It delivers powerful solutions built on open standards for all of the most important technology arenas within today’s enterprise – data center, workgroup, desktop, security and identity, and resource management.”…

Virtualization

SUSE Linux Enterprise 10 is the first enterprise platform to include a fully integrated and supported version of Xen 3.0, the emerging open source standard for virtualization services. Xen 3.0 lets organizations consolidate multiple workloads on a single server. With Xen 3.0, customers can configure applications and systems for maximum efficiency. According to Gartner, the average data center server runs at 20 percent of capacity. With Xen virtualization on SUSE Linux Enterprise, customers will have the ability to increase server utilization to nearly 70 percent.
“SUSE Linux Enterprise 10 is the first enterprise Linux distribution to offer full commercial support for the industry’s fastest and most secure virtualization technology, the open source Xen 3.0 hypervisor,” said Simon Crosby, CTO of XenSource. “With Xen 3.0, SUSE Linux Enterprise 10 can take full advantage of Intel and AMD hardware support for virtualization, delivering bare-metal virtualization performance to enterprise customers. Novell is a trusted partner to XenSource, and we look forward to working closely with Novell to deliver compelling virtualization solutions to enterprise customers.”…
