Red Hat has it both ways with Hybrid Mode

KeithKessinger Keith Kessinger Profile: KeithKessinger

Red Hat revealed a future feature of KVM and Red Hat Enterprise Linux at VMworld 2011 that will allow native non-virtualized applications to run alongside virtual machines and virtual desktops on a host. Called Hybrid Mode, it will eliminate latency issues associated with running workloads inside virtual machines, while still delivering the consolidation and management benefits of virtualization, said Navin Thadani, senior director of Red Hat’s virtualization business.

Virtual machine performance has continued to improve, and more companies are virtualizing tier-one applications. Even so, workloads that require low latency, such as a bank’s financial-trading applications, still have performance issues in a virtual infrastructure.

With Hybrid Mode, you can have bare-metal performance with a native Red Hat Enterprise Linux (RHEL) application on a host that also runs virtual machines and virtual desktops – all of which can be managed through the RHEL interface. At the same time, you can still improve consolidation ratios by sticking workloads normally reserved for physical servers on virtual hosts.

That said, there are some caveats. You will need to use common sense when placing performance-intensive applications on a server with other virtual machines. If the server’s resources are taxed, obviously the workloads will suffer. Also the application is native to RHEL, so it doesn’t have the advantages of virtualization, such as live migration.

Red Hat users shouldn’t get too excited about Hybrid Mode, which will not ship with Red Hat Enterprise Virtualization 3.0 this year.

VMware focuses on end-user computing on VMworld 2011 day two

Lauren Horwitz Lauren Horwitz Profile: Lauren Horwitz

On day two of VMworld 2011 during the technical keynote with CTO Steve Herrod, VMware focused on end-user computing, mobility and desktop virtualization.

At the Tuesday session, Herrod devoted the first 45 minutes of his talk to VMware’s goal to bring anywhere, anytime access to mobile users. One key piece of this puzzle is Horizon Mobile, which delivers work-related mobile applications to devices such as smartphones and tablet computers, and updates to VMware View 5 to deliver a virtual desktop image to workers’ computers.

Herrod and a VMware engineer did a demo to illustrate how VMware has made it possible for workers to separate personal and work identities on phones and tablets. Other key efforts he described include:

  • VMware AppBlast. A new project that allows you to start any application in a HTML5-compatible browser on any device.
  • VXLAN. Technology that facilitates virtual machine (VM) mobility. It provides a layer 2 abstraction to VMs, independent of where they are located.
  • VMware Octopus. A Dropbox-like service for enterprises.

In the second half of the session, Herrod discussed improvements to VMware vSphere 5 to make infrastructure more reliable, available and secure — another effort to support user-focused computing.

Maritz avoids vSphere 5 licensing talk

Colin Steele Colin Steele Profile: Colin Steele

VMware CEO Paul Maritz mentioned “canonical applications” and “cloud” dozens of times each during his VMworld keynote this afternoon. But there was one word buzzword he didn’t mention at all: licensing.

VMware ticked off a lot of its loyal customers last month with its new vSphere 5 licensing policy, which charges users for the amount of memory they assign to VMs. It was the biggest story of the summer, overshadowing the highly anticipated vSphere 5 launch itself.

I know VMware addressed the problem a few weeks later and seemingly placated most of the upset customers. But VMworld is the largest gathering of virtualization pros — 19,000 strong this year — and it could’ve been a good opportunity for Maritz to say how much VMware strives to please its customers and respond to their feedback.

Instead, the elephant in the room went unmentioned.

Veeam scales out with Backup and Replication 6

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

Hyper-V support was the headline when Veeam previewed its Backup and Replication 6 product at Microsoft TechEd. But with the new release, which will begin shipping in the fourth quarter, Veeam’s also branching out in other ways.

A new scale-out architecture is among the additional updates Veeam announced today. Previously, scaling out with Veeam meant adding another Backup and Replication server, which could be managed centrally using Veeam’s Enterprise Manager. With version 6, the Backup and Replication server becomes the manager of separate backup proxies and repositories.

This takes processing load off the main backup server and offloads it to the proxies, which can scale out as needed and improve performance, the company said. Enterprise Manager will remain available, with the added ability to edit and clone backup jobs. (Previously, this product was limited to a read-only reporting role.)

Catbird not buying vShield App, vendors say

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

Catbird Networks and VMware will announce plans next week to deliver VMware vShield controls into Catbird vSecurity.

Catbird disclosed the OEM plans this afternoon in response to a report (since corrected) that said the company would acquire VMware’s vShield App technology.

“There was no purchase of the vShield product by Catbird from VMware,” said Tony Keller, a PR rep for Catbird. “It’s still very much their product.”

A VMware spokesperson also said in an email that the report was “completely false and inaccurate.”

RHEV 3.0 beta supports up to 2 TB of RAM per VM

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

Red Hat is emphasizing KVM’s scale-up capabilities with today’s beta release of Red Hat Enterprise Virtualization 3.0.

The updated KVM hypervisor supported with Red Hat Enterprise Virtualization (RHEV) 3.0 is based on Red Hat Enterprise Linux (RHEL) 6.2. Among its capabilities is support for up to 2 TB of memory and up to 64 virtual CPUs per virtual machine (VM). By contrast, VMware’s forthcoming vSphere 5 will support up to 1 TB of memory and 32 CPUs per VM.

VCP, VCDX losing value, survey says

Alyssa Wood Alyssa Wood Profile: Alyssa Wood

VMware certifications may still look good on your resume, but the value of some has plummeted.

The value of the VMware Certified Professional (VCP) has decreased 12.5% in the past six months, and the VMware Certified Design Expert (VCDX) has gone down 22.2%, according to Foote Partners surveys.

These results are significant downgrades with several likely causes, CEO David Foote said. For one, it’s common for the value of a certification to spike and then lose value over time as the supply of workers with that expertise catches up to the demand, he said — especially when a vendor and training companies push it so aggressively, as is the case with VMware.

“People see [certifications] as a career extension or a place to go for job security, so they go out and get certified,” he said, but the mad rush ends up devaluing the certification in the end.

Killers to play VMworld 2011 party

Colin Steele Colin Steele Profile: Colin Steele

The Killers will headline the VMworld 2011 party.

Today’s announcement of The Killers as the VMworld 2011 party band makes up for several years of lackluster musical guests at the virtualization industry’s premier event. Foreigner headlined VMworld 2009, followed by INXS last year.

The Killers hail from Las Vegas, which, coincidentally or not, will host VMworld 2011. They’re most well known for their 2004 — That’s this century! Good job, VMware! — album Hot Fuss, which has sold more than 7 million copies thanks to hits such as “Somebody Told Me,” “Mr. Brightside,” and “All These Things That I’ve Done.” (Although “On Top” is the best song on the album. This is not up for debate.)

The VMworld 2011 party takes place Wednesday, Aug. 31 at 7 p.m.

Standing out in the market: How startups can fit in

Alyssa Wood Alyssa Wood Profile: Alyssa Wood

As virtualization and cloud vendors make more acquisitions (see: Citrix buying and dive deeper into IT infrastructure (see: vSphere 5), are the small guys getting squeezed out?

Smaller vendors are trying to make a name for themselves and increase competition, which can only be a good thing for customers. These vendors can differentiate themselves by offering capabilities and features that companies such as VMware do not.

“They have to support vSphere at a minimum and have to have a solid angle that is addressing a key pain point,” said Forrester analyst James Staten. He cited workload management, capacity management and workload placement as a few areas where small vendors could shine.

Netflix streaming, VMware licensing and the end of the world as we know it

Colin Steele Colin Steele Profile: Colin Steele

At its core, virtualization is the abstraction of data from the physical world. We tend to look at virtualization as the abstraction of operating systems and applications from servers and PCs, but with this broader definition, it applies to a lot of the changes happening in society today.

Print news is no longer tied to newspapers, thanks to the Internet. Books are no longer tied to bookstores, thanks to e-readers. Music is no longer tied to CDs, thanks to Napster and iTunes and Spotify. Movies are no longer tied to DVDs, thanks to Netflix streaming.

Our whole world has been virtualized.
