Welcome Paul! I enjoyed reading your article.

Re: Defining 'Software-Defined' -- Virtualization Review

JJSim, I agree. Many functions' need for extremely high performance or total control of a computing environment means that placing them in a virtual environment won't work as well as desired. Enterprises sometimes do it anyway because other benefits overwhelm the problems. When extreme transaction processing, realtime computing, digital content creation and other very intense workloads are considered, virtual environments are not always the best choice. This is why I suggest that decision makers understand the requirements of each workload before making broad, product-oriented decisions that are good for many things but, create problems for other things.

If we jump into the wayback machine for a moment, I remember having to write a device driver in COBOL for an organization that had decided that everything must be written in that language.

I was fortunate that this exercise was being done on a Digital VAX/VMS system. The VMS System library included a number of really wonderful things that made it possible to access very, very low level system functions from any language such as VAX BASIC, VAX COBOL, VAX Fortran, VAX C, and VAX PL/I.

I'm fearing that the use cases AppZero is currently promoting and their technology's capabilities and how their technology _could_ be used are being confused here. AppZero's technology is very flexible and can be used in a number of ways, ways that the company currently isn't promoting.

Re: The Day the MacBook Died: A True Backup Story -- Virtualization Review

It eventually turned out that Syncmate was the cause of the problem. After recovering to Yosemite, I removed Synchmate. I then upgraded again. This time, the upgrade worked fine and stayed stable. I'm sad to have to say good bye to Syncmate.

Nigel, when you say dominate are you referring to share of desktop revenues, share of desktop shipments or share of desktop installed base?

Re: Gartner Lists VMware, Microsoft as Leaders in Server Virtualization -- Virtualization Review

DKusnetzky — Thu, 15 Oct 2015 15:40:43 -0000

Painting Gartner with such a broad brush isn't totally reasonable either. I know quite a number of their analysts and they're really good, very knowledgeable and make every effort to create useful research.

MaatDPX, actually the software can make a very good guess if it is in the test environment. Is the steering set straight ahead? Are all 4 wheels turning or not? There are other indicators such as the airflow coming in the front of the car as well.

The agent wasn't kind enough to share what about my configuration was causing the issue. So, I just downgraded to Yosemite and got back to work.

Re: Nutanix and the Problem of Performance Testing -- Virtualization Review

DKusnetzky — Wed, 26 Aug 2015 07:10:30 -0000

Having managed teams of people analyzing performance tests, I can understand vendor concerns about publishing the results of half-baked testing. Minor changes in variables such as memory available, types of storage in use and configurations of the operating system, database engine, and applications can result in major changes in the results. I also understand that if a vendor makes it impossible for reliable labs to publish results that it would be wise to ask them why. It is likely that they are trying to hide something.

Re: Take Another Look at VDI -- Virtualization Review

DKusnetzky — Wed, 29 Jul 2015 07:41:07 -0000

I believe VDI's niche status has much to do with IT observance of Golden Rule #4:

"Good enough is good enough. Although it would be nice
to have the luxury of unlimited amounts of time, resources and funding
and be able to develop every conceivable feature, most IT executives
know that they are only going to be allowed the time, the resources and
the funding to satisfy roughly 80% of requests for new capabilities."

While many of the features of VDI appear attractive, the would require changes in IT procedures, beefing up of server memory, storage and processing power, beefing up of network infrastructure, adoption of new management tools and in the end, many obviously have come to the conclusion that the benefits are simply not worth the effort in view of the move to smartphones, tablets and Web-based applications.

Re: VMware and Nutanix Battle Over Testing and Fear -- Virtualization Review

DKusnetzky — Tue, 14 Jul 2015 14:23:24 -0000

I have spoken with representatives of both companies in the recent past. Representatives of both companies clearly have consumed their own company's kool aide. Both believe that their approach is the best and should win out over anything else. Both companies have interesting technology that, in the right place, can satisfy business requirements.

Why all the hot rhetoric? It sells.

Re: Whatever Happened To the VDI Revolution? -- Virtualization Review

DKusnetzky — Tue, 14 Jul 2015 14:16:47 -0000

Thanks, Jon, for an interesting article.

I'm reminded of something a former colleague at IDC suggested. He would tell clients that adoption of technology often follows the "Five one fifth" rule. That is the new solution must provide five times the performance or operate at one fifth the cost. Otherwise enterprises will largely continue to do what currently works for them.

Rather than quibble over the proper ratio, that is whether the real number is five, four, ten or some other number, the formula appears about right to me. VDI clearly hasn't met either qualification.

That being said, it may be the best solution for enterprises serving highly regulated markets or needing very high levels of security.
