Cisco’s John McCool Talks Virtualization

July 11, 2008 by Robin Wauters Leave a Comment

NetworkWorld published a great interview yesterday with John McCool, senior VP of data center, switching and security at Cisco. McCool sees a great future for virtualization around the company’s most successful product in its entire history, the Catalyst 6500 (and its successor, the Nexus 7000 Series, which was recently unveiled), combined with its own forray into virtualizing the data center with its Data Center 3.0 initiative.

A small excerpt:

What other areas are investment priorities?

Virtualizing services in the branch by centralizing those services in the data center. That’s a trend that’s here to stay. [Application Control Engine] and applications embedded into the network infrastructure would be another area that we’ll continue to drive very heavily.

Do you plan to take virtualization above the network to the server or application level?

You see a component of that already in Unified I/O. So the I/O component, really virtualizing that over a single connection to the network, is very fundamental. And then being able to split that out further in the networking device. That’s getting ingrained in the architecture of the data center, very much touching the connection to the server itself.

Do you plan to invest in another hypervisor vendor, similar to your relationship with VMware?

No announcements to date. We’re continuing to work with all the hypervisor vendors. We are interested in virtualized data centers and to the extent that hypervisor and virtualized servers exist in the data center we think that’s a very powerful construct for customers and one that’s going to take network support.

Exclusive Video: VMware In A Nutshell, By Product Marketing Manager John Gilmartin

July 8, 2008 by Toon Vanagt Leave a Comment

So what’s VMware all about now on a technology level, now that their stock went tumbling and their CEO has been replaced? John Gilmartin, Group Manager, Product Marketing at VMware answered our questions on virtualization in general and their strategy and product portfolio in particular.

After defining virtualization and virtual machines, John dives deeper into what drives prospective virtualization customers (infrastructure consolidation, high availability, business continuity, disaster recovery?). He also shares more on their recently announced VMsafe initiative, which allows trusted partners to ‘peak’ into a Virtual Machine and identify threats from the outside of the operating systems and the applications they try to protect.

John underlines that VMware is offering features far beyond the basic data center consolidation needs; such as life cycle management, Virtual Desktop Infrastructure (VDI), automated provisioning, fail over, disaster recovery and optimize the management tasks for a virtual infrastructure.

All this is part of VMware’s from-desktop-to-datacenter portfolio and makes VMware feel confident and well positioned to compete with Hyper-V from Microsoft.

Gene Fay Leaves EMC, Joins VKernel As Top Sales Guy

July 8, 2008 by Robin Wauters Leave a Comment

After Diane Greene leaving VMware, in comes the story of Gene Fay joining VKernel (check our earlier coverage) as Vice President of Sales. Fay was vice president of worldwide sales and global alliances for the security information and event management (SIEM) business unit of RSA, the Security Division of EMC. He joined EMC after the company acquired Network Intelligence where he was vice president of business development.

Gene seems to be happy with the decision he made:

“I have watched the virtualization space explode over the last five years,” said Gene Fay, “With our innovative virtual appliances for systems management, a very hot market, and a great team, VKernel offers a fantastic opportunity to work with customers who are rapidly virtualizing their data centers and partners that are helping them through the process.”

Rich Wolski on Eucalyptus: Open Source Cloud Computing (Video Interview – 1/2)

July 8, 2008 by Toon Vanagt 4 Comments

A month ago we reported on how you can build your own open source cloud on clusters to make your personal cloud dreams come true! Simply put your datacenter to use by ordering Xen virtualization on the Rocks and then carefully roll it in fresh Eucalyptus leaves.

In order to learn what makes these clouds tick, we have sent our enthusiastic cloud computing koala Toon Vanagt to San Francisco to interview Eucalyptus Director Rich Wolski at the O’Reilly Velocity conference. Below, you can find the first part of this exclusive video interview (we’ll post the second part tomorrow).

Rich’s students came up with EUCALYPTUS, which stands for ‘Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems’ as an open-source tool for doing “cloud computing”. Their tool is designed to stimulate the development, interest, experiments and research into the nascent concept and industry of cloud computing.

Eucalyptus was build in a modular fashion, so it can “mimic” the interface of popular commercial clouds, like the one they started off with, Amazon EC2. The team plans support for several cloud interfaces as long as they are public and well documented.

Rich underlined that Eucalyptus is designed to experiment and not to compete with industrial strength clouds as Amazon EC2. Although with some engineering, one could take parts of Eucalyptus, mature those and scale to specific needs.

When asked about the underlying virtualization experience, Xen is seen as a very useful technology in ‘cloud’ regards. Rich complements Xen on being well documented and conceptually easy to understand and he looks back at the Xen selection as a good first hypervisor choice. Due to the nature of their specific use, parts of Xen would ‘break’ under load and were modified to meet certain stability needs.

As LibVert is used, Eucalyptus should in theory be relatively easy be able to support other hypervisors such as VMware and KVM. If no major wrinkles appear on the development surface, Eucalyptus therefore expects to support VMware and KVM with its 2.0 release, scheduled for early September 2008.

Rich supportively points to the Enomalism elastic computing platform, an open source cloud platform that enables a scalable enterprise IT and local cloud infrastructure. as an alternative open source virtualization system.

Security remains an issue but in some respects, accountability and authentication are an even bigger problem to the open source community than within commercial projects. “In an academic space, where you are not paying for usage, it is not a credit card that you are accounting to, but a user”. So Eucalyptus had to devise a user accounting system that is based on certificates. On top of that components should not be ‘spoofable’, as there is no message encryption in Eucalyptus (yet). Because these messages can be spoofed, Rich’s team had to take care of an open source implementation of Web Services Security to make sure the cloud controllers cannot be ‘fooled’ by malicious messages of doubtful origin.

The shortage of public IP addresses in university environments was solved by using the open source technology VDE (Virtual Distributed Ethernet). [VDE is an ethernet compliant virtual network that can be spawned over a set of physical computer over the Internet. You can see VDE as the software incarnation of a hardware network switch plus attached cables. Using the vde_switch and vde_plug programs you are able to create quite complex virtual analogies of a network that can span several hosts, even across the Internet.

By creating a virtual Ethernet for every cluster allocation and make that a set of user space processes can tunnel through NATs (Network Address Translation). As a downside to this VDE implementation comes a performance penalty. So Eucaluptus is offered with 2 flavors, linked to the SLA-nature in cloud computing. The first option uses the described very flexible ‘Virtual VLAN’ independent of IP-addresses. The second option bypasses VDE and is faster but less scalable as limits user requests to the confines of a single cluster.

Tomorrow, we’ll publish the second part of this exclusive interview. Stay tuned!

Microsoft Eats Own Hyper-V Dog Food, Deploys Homegrown Hypervisor In Its Global Datacenters (Video Interview)

June 30, 2008 by Toon Vanagt 2 Comments

At last week’s GigaOM VIP reception, just before their Structure 08 conference, we bumped into Arne Josefsberg, General Manager Online Infrastructure at Microsoft. He happened to be passing by in San Francisco and kindly agreed to get on record with comments on Hyper-V adoption at Microsoft. As he answered our late night questions, the party was just breaking up (hence the disturbing background sounds).

Update: also check out this article on GigaOM, since Om Malik caught up with Microsoft’s corporate VP of global foundation services, Debra Chrapaty, for a video chat as well.

Although Arne declined to put exact numbers to the amount of servers at Microsoft, he did confirm he is responsible for dozens of datacenters around the world to support the software giant’s online services. To give you an idea, Data Center Knowledge noted from a Microsoft executive that the company is adding no less than 10 000 servers per month.

Here is a datacenter lesson from Arne:

“As Microsoft obviously deploys a huge amount of processor, compute and storage capacity, [the need for] efficiency and utilization become super important to us. We work very closely with the Windows Operating system division. Hyper-V is actually becoming one of our key-technologies to drive better utilization of the hardware. We have Hyper-V in multiple datacenters in the Live-network, in production environments taking live traffic. It’s going quite quite well. So we are very jazzed about Hyper-V and virtualization as a technology to scale out our infrastructure.”

Arne’s team has been working closely with the Hyper-V development team for over a year and did not limit this collaboration to the hypervisor, but also the management tools and on how to manage hypervisors at very large scale.

When asked about cloud computing, Microsoft refers to its ‘Software plus Services’ strategy which combines software on the desktop (still the major revenue driver for Microsoft) with centralized datacenter-based services. Microsoft seems high on its hybrid flavor of cloud computing and hopes to lead the way in this nascent industry as well.
