This feature has many names. Creating a larger config vVol. Creating a sub-vVol datastore. Creating an ISO repository. Etc.
In 7.0U2, VMware added a new feature that supports creating a custom size config vVol–while this was technically possible in earlier releases, it was not supported. Also, I should note that this is not supported by all vVol vendors, so of course speak to your vendor first.
First to review what a config vVol is check out this post:
In short, it is a mini VMFS that gets created when you create a directory in a vVol datastore (most commonly created by creating a new VM). This defaults to 4 GB in size. Enough to store the general VM files; some logs, VMDK pointers, vmx file, and some other frivolities.
The issue though is that this was not large enough to store large things like ISOs or vib files or whatever. So if you tried to upload something to a vVol datastore folder it would fail with an out-of-space issue. And you cannot upload to the root of a vVol datastore because a vVol datastore is not a file system. So you had to use VMFS or NFS to store those objects.
The vSphere “update” releases are much more significant than they used to be–traditionally most of the new features came in the major releases. 6.5, 6.7, etc. vSphere 7.0U2 just released and there are quite a bit of storage-related features.
In a few weeks, I will hit 7 years at Pure Storage. It has been REALLY fun. Helping to build our VMware integration ecosystem, pushing the vVol adoption/use case/efforts forward. Building what I believe to be a world-class solutions team that I manage.
I’ve hit my seven year itch. What is next? What should I tackle? Where can I make a big(ger) impact? What is something that is uncomfortable for me, that will allow me to grow?
Clearly, public cloud is a thing. Like, duh. Our customers see that, the industry sees that, and of course Pure Storage sees that. I think the potential there is really just starting–and I think tapping that potential is really going to accelerate efforts on-premises too. I think some of the work we are doing with Equinix Metal is proof of that.
I’ve focused on VMware, specifically VMware storage for my entire career. My first job out of university was just that. The VMware ecosystem though is not going away, and in fact is doing some really cool stuff too. Tanzu. VCF. VMware Cloud. vVols. NVMe-oF. A lot of exciting and differentiating work in that realm. One could easily remain there and perform super satisfying and impactful work. So continuing my focus there is definitely a great option.
Hello- my name is Nelson Elam and I’m a Solutions Engineer at Pure Storage. I am guest writing this blog for use on Cody’s website. I hope you find it helpful!
With the introduction of Purity 6.1, Pure now supports NVMe-oF via Fibre Channel, otherwise known as NVMe/FC. For VMware configurations with multipathing, there are some important considerations. Please note that these multipathing recommendations apply to both NVMe-RoCE and NVMe/FC.
