Will Virtualization Doom Server Sales?

From the article:

The promise behind virtualization has long been that one well-equipped server could do the work of several. So what happens once customers begin following that idea — and buying fewer servers?

That scenario is cause for concern, according to industry analyst Infiniti Research. This week, the firm published a study indicating that server sales will trail off in coming years, and even decline, as virtualization reduces the need for physical hardware.

The company’s TechNavio online research unit released the findings to coincide with the upcoming Storage Expo conference in London next week.

The study suggests that sales will slow to two percent in 2008 — representing a marked decline from the 5.9 percent annual growth rates that fellow market researcher IDC saw in 2006, and the 8.9 percent from a recent Gartner study.

AMD’s Virtual Experience is a pretty cool marketing/virtual tradeshow where you can view videos and short presentations on a variety of technologies related to AMD — such as SUSE Linux Enterprise in the Novell booth.

Of course, you could visit the other vendors at the virtual trade show, but why not start by checking out the Novell booth and learn how SLE takes advantage of the technologies in the latest generation of AMD Quad-core Opteron processors…

Just wanted to let you know that there is technical overview paper and a great step-by-step “lab” document available from Novell’s website which describes how to set up a lab environment with four exciting (and included, supported) features within SUSE Linux Enterprise Server 10:

  • iSCSI
  • Oracle Clustered File System (OCFS) v2
  • Heartbeat v2 – cluster service
  • Enterprise Volume Management Service (EVMS)

These features are collectively known as the High Availability Storage Infrastructure (HASI) and provides an out-of-the-box capability to implement a fully clustered storage system. You don’t have to pay for clustering as a “premium” services with SUSE Linux Enterprise Server (SLES) 10.

The document gives you step-by-step instructions that will allow you to get your hands dirty and try this out. You can even combine HASI with the Xen virtualization capabilities to implement a live migration of a virtual machine from one physical server to another… similar to VMotion — but again, included with the base OS, SLES 10.

If you’re interested, I also found this “lighter weight” how-to article at SearchEnterpriseLinux.com which talks about how to setup Heartbeat clustering on SLES 10.

IBM’s Developerworks continues to impress me with the level and quality of content related to Linux and Open Source.

Continuing in that theme is the “Anatomy of the Linux Networking Stack” by M. Tim Jones. The article starts out at the OSI 7 layer model and all the way up to the device driver level.

A good read.

A technical white paper is now available from Novell that explains some of the details of what’s supported (officially) in terms of virtualization technology related to SUSE Linux Enterprise Server 10 SP1.

You know what Samba is, right? For those of you who suddenly looked at the title of our blog to make sure you aren’t on the Strictly Ballroom fan site, I’m talking about Samba the Open Source CIFS server implementation. Samba has been around a while and does an excellent job of emulating a Windows system for File and Printer Sharing, WINS Server emulation, replacement of NT 4.0 Primary and Backup Domain Controllers and much more.

I ran across a very nicely done introduction to Samba the other day, something which should help explain the project and product,  how it’s installed and used, particularly to newcomers to this integration method.

Of course there is always the various documentation offerings about Samba either from standard publishing houses or from the community itself, take a good look at the following for a deeper view of Samba’s capabilities:

  • Samba.org – the official site for the Samba project
  • The Official Samba 3 HowTo and and Reference Guide – Like the Holy Bible for Samba, this has just about everything in it to really understand Samba, available in printed or online versions
  • Samba 3 By Example – John Terpstra’s excellent reference guide that walks you through every step of different scenarios for small, medium and large installations, literally a cookbook for getting Samba installed and running in almost any organization.
  • Using Samba – O’Reilly and Associates venerable tome that has been updated to include V3, this online/print book has been probably the most referenced Samba documentation source since the /usr/share/packages/samba files.
  • Samba.org Documentation pages – The most sources all in one spot for Samba, watch this page for new resources as they come available.
  • Samba.org Wiki – The official Wiki site for the Samba Project, get out there and contribute some words if you don’t code!

Enjoy,

If you haven’t taken a look at SUSE Linux Enterprise Desktop 10, visit the product page first.

If you have, then you’re probably well aware that it does offer a substantial amount of applications (all supported) and functionality out of the box – unlike Windows, which comes with SOME, but not ALL of the apps.

For example, you would need to buy an office productivity suite (word processor, spreadsheet, presentation, etc.), project management software, digital photo editor, and more IN ADDITION to the Windows OS.   That makes the ROI possibilities for a Linux desktop even MORE attractive to the bean counters and makes that “automatic upgrade” to Vista and Office 2007 all the more difficult to justify.

SLED includes:

  • Office suite (compatible with MS Office, btw)
  • Web browser
  • Email/Calendar clients
  • Citrix/Terminal Server clients
  • and MUCH MORE!!!

Well, what exactly is that “MUCH MORE” claim??  I’ve created a document which lists many of those additional applications.  I’ll email it to you upon request – just ask.  I’ll let you know when I get it posted somewhere too.  In the meantime…
