VSAN + VCSA– New 2 Host deployment

Hey All

We’re deploying 2 new hosts in our DMZ for some redundancy – we currently only have a single, failing host.

I’ve never utilized Vsan before, so this is a bit new to me.

We’ll also need to deploy VCSA to manage the nodes.
I assume I’ll need to get Vsan working properly before I can install VCSA (since that vm would sit on the storage I plan to use for vsan)?

Any guidance here is appreciated

  1. Well, if your planning to deploy VMware’s VSAN you will at least need to purchase and additional host. In an effort to save some money and minimize the hardware footprint, the best option would be the deployment of StarWind’s VSAN, which doesn’t have a requirement for a witness host or dedicating flash storage for caching.

    They have minimal system requirements, hardware-agnostic and can be deployed on bare-bone Windows Server hosts or in the form of “Storage Controllers” in an ESXi environment.

    We’ve implemented them multiple times in the past, received nothing but kudos from our clients about their support.

    BTW, they also have a free version.

  2. Nope, you can install vcsa into a new vsan. Just be sure to place the check in the box to do so. It will be on the same screen you set the appliance name. For a short time, you will have a single node vsan until you add the second node.

    Btw. In a 2 node cluster, you will need a witness. This witness will not be able to run on either of thee hosts. So expect to deploy a small physical machine to run the witness process (old host would be a good canidate, after you stabalize the hardware of course).

    Going the route of vsan, do some extra study on how the storage actually works. Most of my customers get confused on how they can have 22TB of available storage, but run out of space after putting 11TB of VM data on the system. Hopefully you got vsan ready nodes to make your life easy.
