Yes, the system disk area is similar to the VNX one.

There are a lot of differences, but the system drives are still mirrored across the 4 initial drives.

hello again ....

I found no Document ( in public ) but that is not big deal...

BTW if double fault occurred, what will happen ? DL for system space ?

thanks

The internal structure of the system drives isn’t documented customer facing.

If you have more than one system drive failed then you work with customer service to recover.

when you create a pool, are these system drives included or selectable?
