I have a question for Smart Array P410i .

I built Raid 1 array on P410i.

and I'd like to enable "Disk Write Cache" on this Array Controller.

Drive Write Cache seems to be enabled...

>Cache Backup Power Source: Capacitors

But this controller is without battery?

>No-Battery Write Cache: Disabled

so Do I have to Enable "No-Battery Write Cache"?

or is "Drive Write Cache" already enabled?

hi,

The controller has a battery/capacitor

"Battery/Capacitor Count: 1"

and the write cache is already enabled.

Everything seems to be fine.

Thanks
