I already wrote an article on the NexentaConnect for VSAN product after seeing it in action at VMworld last year. More recently, I had the opportunity to play with it in earnest. Rather than giving you the whole low-down on NexentaConnect, instead I will use this post to show the steps involved in presenting a file share built by NexentaConnect to a VM. In this case, the VM and the file share both reside on Virtual SAN. I will also show you how to simply revert to a point-in-time snapshot of the file share using NexentaConnect. To answer the common question, “can VSAN do file shares as well as storing virtual machines?”, the answer is yes. This post will show you how.
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 first encountered Rubrik at this year’s Partner Exchange (PEX) 2015 in San Francisco. They had some promotional flyers made up labeled “Backup Still Sucks”. I guess a lot of people can relate to that. I had a chat with Julia Lee, who used to be a storage product marketing manager here at VMware, but recently moved to Rubrik. Rubrik’s pitch is that customers are currently stitching together backup software with backup storage in order to backup their virtual infrastructures – there is no seamless integration. Rubrik’s primary aim is backup simplicity – they want to provide a “time machine” like approach for virtual machine workloads.
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.
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.
Last year I published a list of storage vendors and partners that I was planning to check out at VMworld 2013. This year is no different, with a number of new arrivals on the storage scene, as well as some super new cool products from many of VMware’s partners. Whilst this is no means a definitive list of what’s on show, these are the ones that I am particularly interested in checking out this year.
I’ve been having some interesting discussions with my friends over at NetApp recently. I wanted to learn more about their new clustered Data ONTAP 8.2 features and its new scale-out functionality. In the storage array world, traditional scale-up mechanisms usually involved either replacing disk drives with faster/newer models or replacing old array controllers with newer controllers. In worst case scenarios, fork lift upgrades are required to do a technology refresh of your array. Another approach, scale-out, is fast becoming the accepted way of handling storage requirements going forward. Scale out storage is now big news. With scale-out, you simply add additional resources to your already existing shared storage pool.
Over the past year I have been to a number of VMUGs (VMware User Group) meetings and have sat in on some of the NetApp sessions on their clustered Data ONTAP release. NetApp have also realized that the demand is there for scale-out, and they have introduced their very own unified scale-out storage solution called clustered Data ONTAP. Basically, this allows you to take a bunch of different NetApp storage array models and cluster them together to provide a single, unified and virtualized share storage pool. Using clustered Data ONTAP 8.2, NetApp customers can now increase scalability using a scale-out rather than a scale-up approach. Let’s look at clustered Data ONTAP and some of the new features it brings in more detail. Continue reading
