Cannot change Accelerator Ratio on Smart Array 641

I have a Proliant ML350 G3 with a Smart Array 641 raid controller in a raid 5 configuration. Using either firware 2.48 or 2.58 I am unable to change the Accelerator Ratio. It is set at 100% Read with no other options available. I am booting with Smartstart 7.40 to try and change it. If I let the server boot into Netware and use Smart Array Config 2.77, I cannot change it either. There is one logical drive created.

Thanks for any help.

Keith,
SmartArray 641 in default configuration doesn't have battery backed cache.
You cannot use write cache without BBWC, therefore you cannot change Read/write ration for 641 controller.
You can buy and install BBWC Enabler Upgrade
for your SmartArray 641 controller

Thanks. You're right, I looked at another ML350 that I am able to change it on and it does have the module. I'll have to get that ordered.
