Infinite Combinations

We welcome the VMware vCenter Server on IBM Cloud Simulator, bringing Superhero insights to mere mortals.

In the movie Avengers: Infinity Wars, Doctor Strange takes on the daunting superhuman task of viewing all the possible outcomes of the Avengers chances at beating their rival Thanos. With millions of possibilities, Doctor Strange saw only one positive outcome where they succeeded. If only we could possess this skill in IT we could model the ideal hardware configuration with the ideal performance, size, and costs. This power of vision to see the ideal outcome should not be the skills of just superheroes.

How Cloud Providers Win with VMware’s VMC on *

Working with cloud providers is the best and the worst possible decision VMware could have made. For VMware, this is a win in that they see cloud adoption, but for the cloud providers, this is the Trojan horse that will move customers from VMware to cloud-based SaaS solutions and away from virtual machines. First and… Read more »

Sockets, Cores, and Threads – When Performance Modeling, 1 + 1 is not Always 2

Capacity planning and modeling requires a firm understanding of the resources you are using.  Planning capacity solely on workload-defined resources will often get you in trouble and lead to contention or waste. A good understanding of the processor and your workloads can ensure you maximize your resources.   When helping customers onboard to the new… Read more »

Maybe Goldilocks was onto something

Managing a virtual data center and hundreds of virtual machines (VMs) is a lot like the old children’s tale of Goldilocks and the Three Bears: too hot, too cold, too firm, too soft, etc. At some point, you find one that is just right. However, with virtualization, we seem to be on the path of… Read more »

The pitfalls of treating vSphere Licensing as an “All You Can Eat Buffet.”

This is a story on vSphere License Management within vCenter and the chaos that admins endure on a daily basis. A number of years ago, I worked as a Pre-Sales Sr. Systems Engineer at VMware. We often engaged our strategic customers to review their license usage prior to their renewing an Enterprise License Agreement (ELA)…. Read more »

Costing Elastic Scalability with Hybrid Clouds

VMware has now announced its partnership with AWS to host vCloud workloads on Amazon hardware. That means we are starting to see the dream of a hyper-converged hybrid cloud become reality. This convergence brings the need for a new TCO and ROI calculation that dramatically differs from our previous models—so is consolidation ratio back in… Read more »

Rightsizing Can Lower Your Costs Like Magic—But You Need to Get it Right

Rightsizing workloads correctly in the data center can be a dark art. Most tools available today look at vCPU utilization and vRAM usage over the course of a day, week, month, or longer, as well as measure the peak usage of the workload. However, peak workload usage can be misleading. Looking at a history of… Read more »

If it Ain’t Broke, Don’t Fix It—Replace It!

Have you ever visited a data center and seen row after row of servers still in production that should have been retired years ago? I am talking about single-processor, single-core tower servers or behemoth rack-mount servers with four or eight single core CPUs. I still see old servers with vSphere 3.x or 4.x running two… Read more »

Data Center Management Tools Surveys Results

If you have never been to VMworld, especially in Las Vegas, then you need to understand the scope of the event. The user community, partners, and VMware employees provide a unique ecosphere of the totality of IT. Attendees are not here just for the hypervisor anymore. The draw is every major hardware and software vendor… Read more »

You don’t know what you don’t know—but now you can!

All too often, when we start using a new platform, we only scratch the surface of its features. I think about products like Microsoft Excel 2016: the features are so vast, deep, and obscured that I would never know you could merge analysis of pivot tables to find a derived output. Luckily, I found the… Read more »
