EVA 4400 read/write ratio

Is is possible to set read:write ration on EVA 4400 LUNs ?

I can't find this anywhere in EVA CV, it looks like it uses default value when creating VDISK ?

Hello,

why do you want to set something like disk? Luns can be presented as read-only or read/write - no other options there.

Yes I'm aware of that.

But as I know on EVA 4xxx caching ration is 70% read and 30% write.

We're having an impact on disk performance (LUN) inside virtual machines. Read is between 50-100MB/s, but write is only 5-10MB/s, so I'm thinking if changing RW caching ratio to 50:50 is possible, just to do some testing ?
