In this post I will now show you the steps involved in creating a Docker Swarm configuration using docker-machine with Photon Controller driver plugin. In previous posts, I showed how you can setup Photon OS to deploy Photon Controller and I also showed you how to build docker-machine for Photon Controller. Note that there are a lot of ways to deploy Swarm. Since I was given a demonstration on doing this using “Consul” for cluster membership and discovery, that is the mechanism that I am going to use here. Now, a couple of weeks back, we looked at deploying Docker Swarm using the “cluster” mechanism also available in Photon Controller. This mechanism used “etcd” for discovery, configuration, and so on. In this example, we are going to deploy Docker Swarm from the ground up, step-by-step, using the docker-machine with photon controller driver, but in this example we are going to use “Consul” which does something very similar to “etcd”.
Cohesity have released their next version (2.0) of the Cohesity Data Platform. I met Cohesity at VMworld 2015, and I wrote about my first impressions of the solution in a blog post from back in August 2015. In a nutshell, Cohesity are positioning their Data Platform as hyper-converged secondary storage. They want to stop the silo’ing of different storage for backups, file shares and analytics in the data center, and offer you a single platform for all of your secondary storage needs. Now they are ready with the next version, so lets take a quick look at what is coming in this new release.
I had a heads-up recently on a new company, ClearSky Data, who only exited stealth today. I want to make it clear that I have not yet been briefed by the folks from ClearSky, but I am definitely hoping to chat with them at VMworld 2015 (they’ll be at booth 441). Therefore a lot of what I have in this post is conjecture on my behalf. It seems to me that their goal is to help change how
Rubrik, who exited stealth only a few months ago, and launched their r300 series of converged data management appliance, have just announced version 2.0. You can read up of the Rubrik launch here. The 2.0 version has a new service called “Unlimited Replication” and a new appliance to the r300 series, the r348 “Hybrid Cloud Appliance”. Rubrik co-founder and CEO, Bipul Sinha, stated in the press release that Rubrik continues to transform “how companies approach data protection and recovery at scale”.
As usual, there have been loads of things happening over the last 12 months in the storage space. The Solutions Exchange at VMworld is always a great place to meet new storage startups, and get some further information on their respective products and innovations. This year, I’ve made a note of a few startups that I wish to catch up with at VMworld 2015 and find out what issues are they trying to address with their technology, and why should a customer choose their solution over some of the others in the storage space.
Disclaimer: Please note that I am not endorsing any of these vendors. This is simply technology that I am interested in, and something I want to learn more about at VMworld. I’d urge any readers attending VMworld to do the same. For those not attending, my goal is to learn enough about these new startups so that I can write an article about them at some point (if I haven’t already done so).
A couple of months back, I wrote a short article on Rubrik. They were just coming out of stealth mode and had started an early access program. Since they had not officially launched, there wasn’t a lot that I was allowed to say about the company, other than give a high level overview. As they have now officially launched their r300 series of products, along with news of a massive $41 million Series B of funding, I can now share some additional details about their products and technology. Just to recap on what Rubrik do, they are offering a converged and scale-out backup software and backup storage appliance. The Rubrik appliance (Brik) is a “rack and go” architecture, with the ability to scale from three to thousands of nodes (unlimited) using industry standard 2U commodity appliance hardware.
The whole pitch is the idea that “backups suck”, and they want to give administrators a much better back and restore experience, similar to Apple’s ‘Time Machine’ feature.
I guess the next big tech preview at this year’s VMworld was around Virtual Volumes. Yes, we’ve done this before, but this year there were so many vendors showing demos of their VVol implementation, and so many presentations/sessions on the topic that I believe folks are beginning to realize that we are very close indeed to finally having this feature ready. It’s hard to believe that this was first discussed at VMworld 2011, and I alluded to this when I presented a VVol session that I co-delivered with the folks from Nimble Storage at this year’s VMworld.
This topic is going to be huge, and it is going to change the way storage is designed for virtualization environments. And I think almost every storage partner I spoke to at the show is on-board. In fact, “The Register” asked the question last month if there was ANY storage vendor that wasn’t doing a VVol implementation?
I’m not going to get into any technical details of Virtual Volumes in this post – there will be lots of time for this later. Instead, I’m going to share how we believe VVols will now enable Software Defined Storage (SDS) for SAN & NAS arrays, similar to how we have achieved this already with VSAN.
