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 »

The cloud costing models… Modern Snake Oil or the real cure for cloud computing pricing?

If you talk to anyone who sells cloud computing resources, you typically hear the same message: “The cloud will save you money!” But the truth is, it’s very hard to know how much money the cloud can save you. Cloud providers often do a good job of telling you how much an instance with a… Read more »

vSphere 6 EP6 CBT Bug—Is your data center at risk?

We were chatting about a blog post by Andreas Lesslhumer concerning a recent vSphere 6 bug affecting VMs, snapshots, and backups: http://www.running-system.com/take-care-express-patch-6-esxi-6-can-break-backup-cbt-bug/   We discussed comments Andreas made at Tech Field Day 2016, pointing out that VMware identified a VMware Changed Block Tracking (CBT) Bug within vSphere Express Patch 6 for ESXi 6 (Build 3825889) affecting… Read more »

Why rightsizing is now more vital than ever when planning cloud migration costs

In the mid 2000’s when I first started looking at virtualization, the initial value statement for making the leap from bare metal to virtual was consolidation. Prior to virtualization, the traditional compute model distributed workloads to dedicated servers and OS instances. After virtualization, however, consolidation was often based on an assessment, and on rightsizing workloads… Read more »
