Although most of my time is dedicated to Virtual SAN (VSAN) these days, I am still very interested in the core storage features that are part of vSphere. I reached out earlier to a number of core storage product managers and engineers to find out what new and exciting features are included in vSphere 6.0. The first feature is one that I know a lot of customers are waiting on – NFS v4.1. Yes, it’s finally here.
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…
I have been doing a bunch of stuff around disaster recovery (DR) recently, and my storage of choice at both the production site and the recovery site has been VSAN, VMware Virtual SAN. I have already done a number of tests already with products like vCenter Server, vCenter Operations Manager and NSX, our network virtualization product. Next up was VCO, our vCenter Orchestrator product. I set up vSphere Replication for my vCO servers (I deployed them in a HA configuration) and their associated SQL DB VM on Friday, but when I got in Monday morning, I could not log onto…
I’ve been working on some Disaster Recovery (DR) scenarios recently with my good pal Paudie. Last month we looked at how we might be able to protect vCenter Operation Manager, by using a vApp construct and also using IP customization. After VMworld, we turned our attention to NSX, and how we might be able to implement a DR solution for NSX. This is still a work in progress, but we did learn some very useful NSX troubleshooting commands that I thought would be worth sharing with you.
A short note to clarify something that has come up a number of times in recent weeks here at VMware. There have been a number of discussions about whether or not we support NFS over IPv6 on vSphere 5.x, and again, on whether or not we support the VAAI-NAS primitives in the same context. VAAI is an API for offloading tasks to the storage array, but for offloading tasks to NAS arrays, storage vendors need to create their own plugins for the ESXi hosts to achieve this. You can learn more about VAAI-NAS by clicking here. So what about IPv6…
Earlier this week I spoke about our efforts to failover vCenter Operations Manager (vCops) between two sites. In that article I stated that we used vApp containers at DR site, and added vApp variables to the Analytics and UI VMs at the recovery site. While this was painstaking to set up initially, it did provide us with the ability to failover vCops seamlessly to the DR site, with the vApp VMs inheriting their network settings via the vApp construct. At the end of that post, I mentioned a KB article, 2031891, which discusses the DR of vCops using IP Customization…
