Smart Array 5i Controller settings

[donkarnash_1]

Hello,
We have a DL380 with Smart Array 5i Controller with 6*146G HDD which are configured in RAID5. I checked the ACU and the controller cache settings is 100% read and 0% write. I want to change this but cannot see any option to change it. Can anyone advise. Thanks

Do you have the battery backup write cache?

It's a battery that goes on the Controller. It's like a $30 part.

You'll need that before you can change the cache settings.

Hi, I don't think there is a battery for the controller. Do I need HP to provide me one ???

hi

Dl380 G2? or G3?

Some server have a simple 5i controller and other 5i plus which have the capacity to upgrade BBWC in order to be able to change read/write

check this

in case you have 5i plus this is the part you need
