Another hyper-converged storage company has just emerged out of stealth. Last week I had the opportunity to catch up with the team from SpringPath (formerly StorVisor), based in Silicon Valley. The company has a bunch of ex-VMware folks on-board, such as Mallik Mahalingam and Krishna Yadappanavar. Mallik and Krishna were both involved in a number of I/O related initiatives during their time at VMware. Let’s take a closer look at their new hyper-converged storage product.
The embargo on what’s new in vSphere 6.0 has now been lifted, so we can now start to discuss publicly about new features and functionality. For the last number of months, I’ve been heavily involved in preparing for the Virtual SAN launch. What follows is a brief description of what I find to be the most interesting and exciting of the upcoming features in Virtual SAN 6.0. Later on, I will be following up with more in-depth blog posts on the new features and functionality.
In a previous post, I discussed the difference between a component that is marked as ABSENT, and a component that is marked as DEGRADED. In this post, I’m going to take this up a level and talk about objects, and how failures in the cluster can change the status of objects. In VSAN, and object is made up of one or more components, so for instance if you have a VM that you wish to have tolerate a number of failures, or indeed you wish to stripe a VMDK across multiple disks, then you will certainly have multiple components making up the VSAN object. Read this article for a better understanding of object and components. Object compliance status and object operation status are two distinct states that an object may have. Let’s look at them in more detail next.
Whilst at VMworld 2014, I had the opportunity to catch up with the Nexenta team who have been working on a very interesting project with VMware’s Virtual SAN (VSAN). The Nexenta Connect for VSAN product, running on top of VSAN, is designed to provide file services, which allows VSAN to not only store your virtual machines, but also to provide SMB and NFS shares for those virtual machines. I caught up with Michael Letschin and Gijsbert Janssen van Doorn of the Nexenta team to learn more and get a tech preview of the product.
There was a very interesting discussion on our internal forums here at VMware over the past week. One of our guys had built out a VSAN cluster, and everything looked good. However on attempting to deploy a virtual machine on the VSAN datastore, he kept hitting an error which reported that it “cannot complete file creation operation”. As I said, everything looked healthy. The cluster formed correctly, there were no network partitions and the network status was normal. So what could be the problem?
Maxta are another storage vendor that I managed to get talking to at this years’ VMworld conference in San Francisco. Although they were present at last year’s VMworld, they only announced themselves in earnest last November (11/12/13) with the release of the Maxta Storage Platform (MxSP). I spent some time with Kiran Sreenivasamurthy, Director of PM & PMM at Maxta, and he was very open in sharing details on the Maxta product.
If you read the blurb on Maxta on the VMworld sponsor/exhibitor list, it states that they eliminate the need for storage arrays, provide enterprise class data services and has full virtualization integration from UI to data management.
So on the face of it, Maxta is another converged solution, similar in many respects to VMware’s own Virtual SAN, Nutanix, Simplivity, etc. So what makes Maxta so different? Kiran shared his views with me here.
As many of you are aware, I was at VMworld in San Francisco last week. I wrote a number of articles about some VMware storage announcements, such as EVO:RAIL, VAIO and VVols. However there were, as usual, quite a number of storage vendors at this years conference. One of the vendors that I really want to learn more about was Kaminario, an all flash array vendor that I’d heard a lot of things about. I had the pleasure of spending some time at the Kaminario booth with Shai Maskit who is a senior Product Manager with Kaminario. I posed my usual set of questions to learn a bit more about their AFA products. Continue reading
