Can I mark a local RAD1 as SSD when the ESX is not recognizing it as one in 7.0.3

[erickpty]

Good day,

Can I mark a local RAD1 as SSD when the ESX is not recognizing it as one in 7.0.3?

This is a pair of Dell SSD in RAID1 (EXS+datastore1)

I looked here: https://kb.vmware.com/s/article/2013188  but the article is for nmp and my RAID does not show in nmp.

Here is my config:

[root@ESX02:~] esxcli storage core device list -d naa.62cea7f0c4cce400298be079e4cd3c7d

why do you need to mark it as an SSD?

[erickpty]

Because that RAID1 is made of 2 SSDs.

/dev/disks/naa.62cea7f0c4cce400298be079e4cd3c7d

is a Raid1-array - not a SSD

Yes you can mark it as SSD if you like or have a need fore. If there is already ESXi content like .locker, ha or other system related stuff on it you will get an error and a host reboot is needed to take changes effect. If not than ESXi can do it on the fly during runtime.

Does is make sense? Most likely not because speedwise it does not make any difference.  ESXi needs to know if its a SSD when you would like to use a disk for Cache,Swap or ....

But if you mark it as SSD it won't change anything when it comes to ESXi and how it uses the device?
