ESXi Hardware RAID ISSUE.

Hello,

I have A Dedicated Server of Asus & Supermicro, I am trying to Configure Intel Hardware RAID on ESXi 7.0, Like I am trying to Configure RAID 0 With 2 Disk on 1TB After Configuring RAID From Intel Bios, and after that, I boot up to ESXi and during Installation, it shows 2 Separate Disk of 1TB but it should show 1Disk of 1TB, Any Solution For that?

Intel RST/RSTe is not true hardware RAID. It is pseudo-RAID/software RAID.

For ESXi RAID, you need a true hardware RAID controller that is found in the VMware ESXi HCL.

Any Solution For that?

Yes, use a supported RAID controller and supported server-class hardware. Also, unless you truly don't care about your data you should never be using RAID-0 for a VMFS datastore.

So it means I will not be able to create a Hardware RAID on intel based controller, is there any way to configure Soft RAID.

OK Hardware RAID is not Supported Except HCL as replied below, Noted That.

Is there any way that I can configure the Soft RAID VIA CLI Method, For Ex Something zpool, in ZFS Filesystem.

Not in ESXi there is not. And software ("fake") RAID is generally terrible and should generally be avoided.

oh that's sad because there are other hypervisors like proxmox which support's both, also I'm sure ESXi is not based upon any Linux distro.

Correct, ESXi is not Linux nor is it based upon it.

"you should never be using RAID-0 for a VMFS datastore"

Why?

It looks like Intel RST Volume Management Device (VMD) with RAID 1 for NVMe drivers is supported as of early 2022 for both boot and data volumes:  Using Intel VMD driver for vSphere to create NVMe RAID1

I have no idea whether using Intel VMD for RAID 1 is a good idea or not. But, RAID 0, even if it was supported, remains a horrible idea regardless 🙂
