We like our IBM blades. We have lost a few Management Modules, which is
funky and it took us awhile to get 802.1q trunking working with our Cisco gear.
But all in all we like love the remote management options and the blades have
been stable. What issues are you having?

Now if only IBM made fricken blades that fricken work maybe they'd have
something.

IBM Offers New Take on Thin-Client Computing

IBM's new virtual desktop solution emphasizes a centralized, host-based
infrastructure and a lightweight, terminal-esque desktop-and virtualization, too
by Stephen Swoyer
10/25/2005
With its twin emphases on a centralized, host-based infrastructure and
lightweight desktop processing hardware, IBM Corp.'s new PC blade
infrastructure smacks of technology initiatives past. But there's a very new
wrinkle in IBM's vision that could make it a compelling technology solution:
virtualization. Call it the mainframe-ization of the desktop.
A decade ago, a band of technology CEOs-including Oracle Corp.'s Larry
Ellison, Sun Microsystems Inc.'s Scott McNealy, and former IBM Corp. chief
Louis V. Gerstner-celebrated the emergence of a new host-based client computing
model. Proponents of these new "network computers" tallied up their advantages
over bloated, standalone PCs and confidently predicted the inevitable, if not
rapid, demise of the Wintel duopoly's bread-and-butter platform.
Wintel is still going strong, of course, and desktop PCs are more bloated
than ever. In spite of the hype, however, network computing does offer
compelling advantages, particularly for task-based or knowledge workers who
don't need multi-gigahertz PC behemoths on their desktops. As a result, network
(or thin client, as it's now called) computing remains a viable model-albeit
one that's more the provenance of terminal purveyors like Wyse Technology than
database and enterprise applications specialists such as Oracle.
But IBM's new Virtualized Hosted Client Infrastructure isn't just an updated
or renamed thin-client computing solution. For starters, Big Blue is getting a
technology assist from x86 virtualization specialist VMWare and thin-client
computing stalwart Citrix Inc. IBM's plans calls for a healthy dose of its
xSeries and BladeCenter Intel-based servers, VMWare's ESX Server technology,
and Citrix' Presentation Server client-access technology.
In this respect, the Virtualized Hosted Client Infrastructure is quite
different from the thin-client solutions of yesterday-or today, for that
matter. Instead of requiring the use of a single multi-user operating
system-i.e., Windows or Linux-with all of its attendant disadvantages (e.g.,
comparatively poor linear scalability in large SMP configurations, limited
performance and efficiency, and complex administration), IBM's solution taps a
virtual operating system host (VMWare's ESX Server) that can support dozens of
discrete Windows or Linux operating system instances.
While no one would argue that VMWare's flavor of virtualization is as robust
as z/VM, few would deny that it's probably just the ticket for supporting
typical task-based or knowledge workers. More to the point, because ESX Server
lets organizations effectively micromanage their server capacity (exploiting as
much as 80 percent of an xSeries server or BladeCenter system's CPU compute
resources) they can support more Windows or Linux users on a single piece of
hardware than they could using a multi-user approach.
The Mainframe-ization of the Desktop?
The parallels to mainframe capacity management and mainframe client (i.e.,
terminal) access are striking. After all, zSeries operators can maximize
mainframe capacity by micro-partitioning operating system images and workloads
across tens, hundreds, or even thousands of logical partitions (LPAR). They can
easily deploy new images or workloads when the need arises (and if there's
capacity to spare), or re-deploy existing workloads if there isn't. And while
IBM's Virtualized Hosted Client Infrastructure isn't quite that scalable, it
will enable a previously undreamt-of degree of "desktop" capacity utilization.
Best of all, the desktop hardware complement to this back-end processing
horsepower amounts to little more than a high-resolution display terminal.
For these reasons, IBM says its new Virtualized Hosted Client Infrastructure
has all of the advantages of the thin-client or network-computing models with
few, if any, of the disadvantages. Big Blue's virtual Windows or Linux
operating system instances should be easier to manage, secure, and back up.
Cycle for cycle, they should also be more efficient than competitive PC blade
offerings from ClearCube (PC Blade) and Hewlett-Packard Co. (Consolidated
Client Infrastructure). They support most typical end user amenities-printing,
audio, and USB connectivity-and can also support multiple monitors.
The question, of course, is whether IBM's virtual thin client will suffer the
same fate-niche-dom-as that of its network computing forebears. "On paper, the
relative values of network-enabled "thin client" desktop solutions make perfect
sense. Such solutions provide all the applications and power needed for typical
knowledge workers but significantly ease and improve IT performance and
security by centralizing systems management," notes Charles King, a principal
with technology consultancy Pund-IT Research. "But while this concept offers
provable merits, the vast majority of businesses have chosen to stick with the
same old 'employee in every cubicle and a PC on every desktop' approach."
Nevertheless, King suggests, there are a number of reasons why things might
be different this time around. "[A] confluence of factors could be pressing the
market toward a fundamental change. First and most importantly, with most
companies taking an increasingly pragmatic approach to their IT investments,
the cost-effectiveness of hosted desktop environments is likely to garner more
favorable attention than in the past," he writes, noting that companies are
supporting increasing numbers of remote workers, too.
IBM's virtual desktop offering could be an ideal solution for them. "At the
same time, increasing access to Internet-based high-performance network
solutions makes it much easier for remote workers to stay connected to their
employers," King concludes. "In other words, the IT infrastructure required to
support blade-based desktop solutions is more readily and easily available than
it has ever been."
