Hi, Thank you for your video I want to setup a new vSAN 2 node system. for a witness separate host (server). Do I need to buy a vSphere license to deploy ESXi and witness appliance there?
Really good question. The witness appliance is a ESXi host in a VM format. So it needs to run on an ESXi host. Now before Broadcom you could run it on the Free version of ESXi, but they dropped that.. So looks like you will have to have a licensed copy of ESXi for the witness to run on. As usual check with your Account rep.. Have a good one.
Super Channel, all your videos are great. I learn something from every one I watch. Can you do a future video where you setup a Home lab environment 2 Node vSAN ESA on using non certified equipment? Cover issues, gotchas, etc. Cover in a video migration from data on a local disks to a vSAN ESA setup? I'm planning to setup a 2 node home lab but already have disks (NVME) and host, would like to migrate from local disks to vSAN ESA for redundancy.
Thanks for watching and the super thanks. Appreciate it.. I won't be able to the do the video on non certified equipment, as I don;t really have it. I use VMware Workstation for most of my lab.. the main thing to look out for is the network card and the disk controller. Make sure ESXi recognizes both.. As for transferring local disk to vSAN.. I will assume you want to use the vSAN datastore as a backup for you files.. It is not really designed for that, but I can do a video on setting up the vSAN datastore as a file share.. Thanks again for watching and you have a great day
Hello You dont need to run esxcli "vsan network ip add -i vmk0 -T=witness" on each host ? or it have been added automatically because you used quick wizard setup ?
Thanks for watching. The only time you would need to run that command is if your vSAN network (the vmkernel ports used for vsan) is unable to reach the Witness vSAN network. I.E You do not have routing setup.. at that time you need to tell vSAN which vmkernel port to use to reach the witness host.. Hope this helps.. Have a good one.
Hello, let me ask questions, please. 1. If we connect nodes directly to each other for vSan traffic, and put the command for witness communication through management, then what happen when we loose management traffic for a host isolation? We know that we might loose management traffic but HA has ability to check if the host is truly isolated or not communicating with datastores. My question is, what would happen if we lost management traffic but host is not really isolated? 2. I assume we can use 2 Node vSan cluster for "room" failure, right? Let say put each node in a separate rooms and create 2 Node vSan cluster. In this case, can we use affinity rules to distribute VMs compute between both hosts? Part of VMs running on one host other part on second host and when failure occurres, all VMs run on survived host? Thank you.
Great Questions.. Question 1. vSAN with HA does not use Datastore heart beats, unless you have some form of shared storage between the host other than vSAN.. To answer you question, if the management network fails, both node would still be able to see each other on the vSAN network, but they won;t be able to see the Witness, so vSAN would still function. Just treat it as a Witness Failure. Just check this article.. core.vmware.com/resource/vsan-2-node-cluster-guide#sec7423-sub1 Question 2. Don't see why you can't do that.. Thanks for watching and have a great day.
