The big portion of it is the VDIs, XenDesktop VDIs. I would say that our biggest deployment for VDI is approximately 15,000 users.
Our team actually maintains the solution and deploys the updates, etc. We have two people that handle all maintenance-related issues. Mostly me but I have support from another person.
VxRail does not require fiber switches or external storage. It's easy to replace and manage. It's centralized management through VxRail Manager.
The upgrade process is still not finished up. Sometimes during the upgrade process of VxRail, we experience errors that have nothing to do with reality and I cannot troubleshoot them without calling Dell and bringing in an engineer to figure it out.
If the VxRail upgrade fails on one of the particular nodes in the cluster, it doesn't stop, It pauses. When a problem's fixed and you retry it, it starts from the beginning.
For example, If I have 32 nodes in a cluster and I have a problem with the 31st node, I have to start from node 1 to check everything. To get to node 31, it takes up to three hours.
I have been using VxRail for three and a half years.
Stability is not related to VxRail. It's related to vSAN. Because VxRail has nothing to do with vSAN. VxRail's just aiding automation and the orchestration processes to vSAN, the VMware vSAN. Overall, the stability is pretty good if the hardware is stable.
The scalability is 10 out of 10. I can add or remove hosts at any time. I have no problem with that.
I'm really pleased with the technical support because it's centralized. It's not just VxRail support, it's hardware support and vSAN support, VMware support. If I call Dell for any problems relating to VxRail, I don't have to call anybody else.
In any case, if we need VMware engineers, it's just a matter of internally bringing somebody on the call, and then we figure it out together.
The initial setup is straightforward. As soon as I prepare a JSON file I have no problem.
Usually deployment depends on the number of nodes — it's taken up to two hours.
I was not involved in the licensing of this solution.
If you're interested in using VxRail, use your judgment. There are multiple solutions and all of them are geared toward different use cases. Some people will prefer HyperFlex, others will prefer to go with Nutanix, VxRail, or, for god's sake, vSAN ReadyNodes.
VxRail has some limitations. For me, it's limited from doing what it's supposed to do because it's provided by VxRail — it's automated and orchestrated by VxRail. For example, I cannot use VMware Update Manager. I have to use a bundle, which is produced by Dell, and usually, they are at least a month to a month and a half behind VMware.
Overall, on a scale from one to ten, I would give VxRail a rating of eight.
