Very informative, very clear, very easy to understand videos. I think that those are the best informative vSAN videos I’ve ever seen in the UA-cam. Thank you very much. One little correction for 16:35 if I don’t misunderstand what you said: Actually there is a limit for the number of the SSD/NVMe drives per host, it’s 24 NVMe drives per host maximum as for 8.0 U1 for the time being.
Nice catch.. From what I was told. vSAN ESA does not have disk limits like OSA. The limit is more on the host side of things. Check out config max and look under vSAN.. Drive limits are mentioned for OSA. Hope this helps and have a good one.
very nice video, a couple of comments: - HCI infrastructure are more used today than a couple of years ago, but mostly on large enterprises (DELL VXrail, Vsan Ready nodes) - if you go on the VMware configurator now raid-5 can be done also with 3 hosts. keep on with this kind of videos that elevate the level that is on Internet just made for home labs....
Thanks for the info.. As for the RAID 5, The documents still show that you need 4 fault domains. (Hosts). Now if you have "Force Provisioning" set to yes, it will let you do it with 3 hosts, but you have no protection.. I will do a video discussing force provisioning and go over this. Thanks again for the comment, and have a great day..
I stand corrected. Just noticed that the new ESA vSAN will allow a 2+! Raid 5, therefore only 3 hosts.. I will have to update that. Thanks for bringing that to my attention..
I would like to express my sincere appreciation to Mr. Steve for his dedication, hard work, and valuable contributions. I strongly encourage all system administrators to take full advantage of the lectures he has shared.
Thanks, Steve, for your excellent work. I have a question: I have one host with 12 SAS, which has 12 disks (12TB each) and 2 NVMe drives (2TB each). Additionally, I have two other hosts. Each host has one SSD disk (1TB) as a cache without SAS disks. What would be the ideal solution to implement vSAN with this configuration? What is the perfect solution to make vSAN with this
Since you have a mix off SSD and SAS, you will need to create Disk groups on each server. Each disk group needs at least 1 SSD for cache and 1 SAS for Capacity.. You 2 other servers will need to have some SAS Drives installed. Thanks for watching and have a great day
In my work we have spent alot of time defining logical data stores to be associated with 1 and only 1 physical block array and we monitor the health of each LDS and the VMs attached to it so we can find noisy apps/VMs that are choking physical devices. How do we monitor the performance health of disk i/o between VMs read/writes and the physical storage with VSAN when it sounds like all VMs do read/writes through one LDS ?
Great question.. I will do a performance vid for vSAN really soon.. You can still look at the VM's performance and in the individual disk performance which I cover in my Performance series.. Thanks for watching and have a good one.
unhealthy status on vsan disk: I have 6 hosts in my vCenter that have their disks participating in vSAN. Due to some disks testing, I had to remove one of the disks from vSAN several times and replace it with a new one. Ultimately, this caused an "unhealthy" error to appear in the disk management section of vCenter, with a red icon next to the disk. Now, the entire disk group is in an "unhealthy" state, and that disk group is in out of service. Is there a hardware issue with this disk, or is there a firmware problem on disk? I doubt it's a hardware issue since we purchased this disk recently. If you have any solutions, I would appreciate your guidance. Thank you.
Sorry to hear this. Sounds like perhaps the cache drive is offline.. (assuming this),. It could be a firmware issue or even a controller issue. I am not sure what brand server you are using, but I would reach out to the manufacturer and see if there are any updates available or any service bulletins for the drives or controller. Have a good one
@@TechUnGlued Thank you for taking the time to answer my question. If the issue is with the SSD firmware, how can I fix it? How can I update or reinstall the SSD firmware? my servers are HP Gen10. Thank you again.
@@sabamailfarajollahi8189 Hello. We are assuming here.. Reach out to HP and see if there are any updates for your server.. That is where I would start first. If things are up to date, then you will have to ask them why is the same drive failing several times.. See if there are diagnostics you can run on it. I am not an HP server expert, but I am sure the server would have some sort of logs in iLO capturing the errors. I don;t have the server in front of me, so quite difficult to diagnose from here.. Al else fails reach out to HP support/
Thanks a lot Steven. Was waiting for vSAN series. Will be waiting for the remaining ones for the series.
Your welcome. P2 coming real soon
Thanks!
Thanks so much for the super thanks. you have a great day

Thank you for the vSAN content. Looking forward for the installation and set up videos.
You bet!. Part 2 very soon. Have a good one
Excellent Job!
To make the presentation even more well-organized, I suggest associating each concept with a PowerPoint slide ...
Thanks for watching. Good advice. Have a good one.

Simplified teaching make a dumb to understand the principle very easily.

Thank you soo much im really excited for this vSAN series all the best
I'm glad you like it. Have a great day
Thanks Steve for this wonderful training...
My pleasure!
Thanks Steven. It is easy to follow up. Can you please post a video for vsphere HA in more details configuration and settings ?😀
Thanks for watching. I have this video on HA.. Let me know if there is something missing. Have a good one..
