The fairytale of Hypervisor Commodity

We hear some people chanting that the Hypervisor is a commodity. What they actually mean is that for an administrator it doesn’t really matter that much if his Windows VM / Application is running on an ESXi, Hyper-V or KVM host. We have a certain level of maturity in virtualization that the differentiation of choice is in higher levels of management. What is a commodity? A commodity is a service/product where the choice of manufacturer/vendor is irrelevant and interchangeable without any impact on the consumarization. In technology we can plug a server in 220V power off the grid the same

you startups challenge my basic knowledge

DISCLAIMER: the companies named in this blogpost COHODATA: sponsor of Storage Field Day 4, where I was an attendee and my T&E was covered by the collectiveness of all sponsors. DIABLO TECHNOLOGIES: a very recent out-of-stealth technology with whom I have no affiliation (yet?) SCALECOMPUTING: I am currently working on a marketing project to help ScaleComputing with brand awareness. If you want to read this post as sponsored by them I will allow you to 🙂 Today I got inspired by J.Metz’s article The Napkin Dialogues: “Open”-ing up to SDN where he admits being caught in speed by new technologies. Sometimes

Say nay to the naysayers – serverside storage for believers

DISCLAIMER: I am currently working on a Marketing project for ScaleComputing, one of the players in the HyperConverged platform market. The heat is on! That’s the least you can say about datacenter marketexture. There are two big trends going on in the datacenter design:  on the logical side we are drastically changing from a client-server age to cloud-computing age (or however we are going to call this era in 10 years time). on the physical side we are drastically changing from a silo-design to a node-based design. this goes hand in hand with the ‘software-defined’ trend Most of you know

The Economics of VSAN – it’s all in the design

Thank you for everyone that got in touch after my “Is VSAN affordable” post of a few days ago. I have enough new thoughts to give the post the extent it deserves and share a few new thoughts/questions. First of all it has become pretty clear that my assumptions that the VSAN VDImark benchmark was CPU constraint appeared to be correct. The only true conclusion we can make from the original VMware post is that VSAN in G.A. has more CPU reduction than in beta which made them able to run about 5% more VDI seats on the same CPU’s.

is VSAN more affordable?

I was very pleased to see actual results coming on the VMware blog concerning VSAN 5.5 GA benchmarks in the lab. First of all please read the blogpost first before going to my analysis/questions. Secondly if you are looking for answers, this is not going to be the place as I am just going to ask more questions. That being said let’s have a look at the actual results. If we simplify the results of the benchmark these are the finding: VSAN does scale lineair, up to 1600 heavy duty VDI’s on a 16-node cluster response times scale linear as

Products are sold, tools are free!

Everyone knows I am a huge community fanboy and I will highlight when a vendor acknowledges the community with free tools. A great historical example was Veeam FastSCP. Veeam had done a lot of work optimizing the traffic in and out of ESX(i) hosts for backup purposes that they released a free tool for the VM admin to get the same benefits for their manual transfers like ISO’s or VM templates. Today one of the leaders in free tools from the vendor side is definitely Solarwinds. Not only do they have a very thriving tech community (THWACK) that is second
