Colleagues who have experience with RAID on SSD in ESXi 6.x?

Question

System administration

There is a patient in the form of ESXi, the patient has been getting worse and worse lately ... I.e. slow down became "raids"!
Works for a long time and mercilessly on HDD, and without a RAiD array, solo.
And since many of us took the oath of our iT Hippocrates, the idea came (in the form of catching up from the boss) to bring a valuable patient back to life by transplanting instead of a worn HDD - SSD implant, and even in a RAiD array.
I heard many healers know about the intricacy of this adventurous event... There are rumors about 100% compatibility of ESXi only with INTEL SSDs. And there is something "ay-yay-yay" about RAiD ... What can you say about this case, gentlemen? How to avoid pitfalls in the "kidneys"?

Ps It is planned to use disks of 500 GB each.

Answer 1

ESXi is whimsical to iron RAIDs. They are highly recommended to him. But a limited number of models.
No problems were noticed with SSD (through RAID, of course, not directly).
Nuance - ESX does not recognize disks as SSDs. You can force it to do so using the command line method. But, IMHO, not necessarily. Didn't notice the difference. From that, ESX thinks that it does not have an SSD - it works the same way.

Answer 2

Any SSD will work, but the RAID controller will only work from the ESXi compatible list. Software RAID controllers (which are built into the motherboard) are completely ignored by ESXi. A RAID 1 array created on a compatible controller is recognized by ESXi as a "non-ssd" disk, the hypervisor does not know anything about the SSD models themselves, and it doesn't care what disks are there.
