While visiting Cisco Live in Milan this week, I was honored to present at the Cisco’s “Engineers Unplugged” show. Together with my Italian college and personal friend Fabio Chiodini we drew up a relatively new architecture for shared storage.
In this session we showed how you can basically use servers with local storage attached to deliver shared storage out of a software layer.
There are many products out there today that use this storage architecture. During Engineers Unplugged we only described the architecture and didn’t really go into specific products.
This new approach of delivering shared storage purely out of software is some of the new magic that we are starting to see out there. As the trademark of Engineers Unplugged seems to be drawing unicorns, we decided to include a unicorn right into the presentation:
“From hippo to Unicorn… It is easily done in software!”
@Lauren: We beat you to it this time 🙂 Shared storage out of software is so much magic we felt the unicorn should Read the rest of this entry »
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 »
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.
These technologies look south for their storage requirements, abstract this storage and Read the rest of this entry »
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 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 »
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 »
Looking through VMware’s newly announced things at VMworld 2012, the one thing that stood out for me was vSAN or (vCloud) Distributed Storage technology. From what I’ve seen at VMworld sessions, the vSAN technology creates a “distributed storage layer” across ESX nodes in a cluster – yes, up to 32 of them. Disclaimer: Even though I work for EMC, I have NO further insite into this development, nor do I blog for EMC. These are my own thoughts and ideas.
Just a VSA on steroids or way more?
So what is this distributed storage technology? At the first glance, it would appear to be something much like the VSA, but its implementation would be more comparable to Read the rest of this entry »
Announced this year at VMworld 2012 (Watch the Monday general session from 51:26) were several cool technologies coming from VMware in the near future that focus on storage, or rather vStorage: Virtual Volumes (vVols), Virtual SAN (vSAN) and Virtual Flash (vFlash?). So what is this all about, and where is it going?
Virtual Volumes or vVols
How SAN and NAS systems work today, is something that they have been doing for years: Take a bunch of disks, stripe data across Read the rest of this entry »
