Mark as flash Disk?

[RKDRnD]

Hello all, I have a few questions about this feature.

1. What does "Mark as Flash Disk" actually do?

2. Is there an advantage of marking an SSD LUN which is falsely recognized as HDD as Flash Disk, in a non-vSAN cluster. In this case the LUN is presented from a SAN backed by a pool of physical SSD drives.

3. In a scenario where a LUN presented comes from a tiered SAN pool, i.e.: mix of HDD and SSD drives where Software-Defined SAN moves hot\cold blocks up and down from\to HDD and SSD, would it not be recommended to mark that LUN as FLash Disk?

Hi,

I would also be interested in an answer on that questions.

Is there a deeper reason no one can answer this for two years? Hello, is there anybody out there ...?

No, there's no benefit. This was added to the UI just to make it easier to change the incorrect identified devices for vSAN. It doesn't do anything other than that.
