EVO:Rail – VMware enters the hyperconverged space

A very exciting announcement was made at VMworld today: EVO:Rail. I’ve known for a while about this under the codename “Marvin” (and EMC’s appliance related to this codenamed “Mystic”), now it is out there with it’s official naming. But what is it? Disclaimer: I work for EMC, but what I write here are my own opinions.

First things first: A quick intro to hyper-converged

First we had converged infrastructure. Converged infrastructure operates by grouping multiple components together into a single, optimized computing package. Components of a converged infrastructure may include servers, data-storage devices, networking equipment and software for IT infrastructure management, automation and orchestration. VCE’s Vblock is a prime example of converged infrastructure. Below that we have reference architectures like EMC’s VSPEX and NetApp’s Flexpod.

So on to even higher integration and automation: “hyper-converged”. Hyper-converged architectures consolidate and manage compute, Read the rest of this entry »

Software-defined Storage = Virtualized Storage = vSAN?

I recently get more and more into discussions around Software-defined storage and storage virtualization. Is it the same, is it partly the same, is it something totally different? In this blog post I’ll try to shed some light on the technologies of today around these buzzwords and try to make some sense at the same time.

What we used to call virtualizing storage

Before we launched the idea of the Software-defined Datacenter (SDDC) and Software-defined Storage (SDS), we were already putting hardware between storage and hosts creating an abstraction layer between the two. Good examples of this technologies are IBM’s SVC and EMC’s VPLEX.

A good example of abstraction of storage from the underlying hardware - VPLEX in a metro configuration abstracting the underlying storage to add value of stretching a LUN across phyisical locations

These technologies look south for their storage requirements, abstract this storage and Read the rest of this entry »

Software-defined Storage: Fairy tale or Reality?

Nowadays the air is filled with the Software-defined Datacenter or SDDC for short. The idea behind this is awesome: As soon as we are able to define and manage compute, storage and networking using software only, we can define, build, scale and destroy virtual datacenters at the press of a button. On top, there’s a web portal. Underneath, there is just a generic x86 hardware platform.

Software-defined Storage

Software-defined compute is something that has been going on for years already. Most vendors that sell hypervisors, especially VMware have a lot of work into the software-defined pillar that is called “compute”.

But when we look at the storage component of the Software-defined Datacenter (often called SDS or Software-defined Storage), things aren’t as advanced as in the compute pillar. Or are they? Read the rest of this entry »

My Dutch VMUG 2012 presentation: Software Defines Virtually Everything – Storage

Last week I did a presentation at the Dutch VMUG event around SDDC with a techical focus on the storage bits and pieces you could build inside the hypervisor to accomodate this. I want to share this presentation with you together with a little background on the subject.

Software Defines Virtually Everything

VMware has taken a big step towards the Software Defined Datacenter (SDDC). This is where things are going for sure (also see my related post Cool Tech Preview: VMware’s distributed storage). The idea is that since “everything” runs on x86 anyway, you can potentially run all code on a common platform. From that view, everything will run in software. Read the rest of this entry »
