StoreVirtual 4330 - enabling Physical Drive Write Cache and changing Cache Ratio

Hello guys,

 

We have some StoreVirtual 4330 SAS nodes to "play" with. We are doing some performance tests and we'd like to test with different cache ratios on the Smart Array and with DWC enabled and disabled. The problem is that the Lefthad OS seems to overwrite the settings we set in the Storage Administrator (before boot). I've checked and if the Lefthand OS doesn't boot, the settings remain in place. If it boots, the cache gets set to 50/50 and the DWC is disabled. Is there any way we can override this behaviour?

 

And yes, I know it may not be a supported configuration and that normally DWC doesn't make that big of a difference, but we need it nonetheless :)

 

Thanks!
