h730 has a cachebypass setting that can be changed through perccli

But neither perccli manual nor poweredge-rc-h730/330-userguide provides any details of this mode.

CLI reference guide gives only information about the way to change it

I.E

This command sets the cache bypass size and cache bypass mode on a virtual drive.Input example:

perccli /c0/v0 set cbsize=0 cbmode=7

Options:

cbsize:

0 — 64k cache bypass

1 — 128k cache bypass

2 — 256k cache bypass

cbmode:

0 — Enable intelligent mode cache bypass

1 — Enable standard mode cache bypass

7 — Disable cache bypass

 

Where can I find information about Cachebypass Modes ?  Specifically how "intelligent mode" is different from "standard" mode. what type of IO are bypassed, what are pros/cons of enabling/disabling this mode ?
