Array accelerator vs Drive Write Cache on P410i (DL580 G7)
Hello.
I'm newbie on this forum and need your help.
I work with P410i controller but don't understand the difference between the Array Accelerator on the logical device and the Drive Write cache on the Controller.
Can I use Accelerator without drive write cache ?
Someone can help me ?
Thanks for your help.

Re: Array accelerator vs Drive Write Cache on P410i (DL580 G7)
Thanks for your response.
Can you confirm me if the option "array accelerator" works alone. Must I active the option "Drive Write Cache" to use the array accelerator ?
I understood the "Drive Write Cache" is the physical drive cache and not the controller cache and the array accelerator is the controller cache. Correct me if I'm wrong ?

Thanks a lot.
So, this white paper confirm my understanding, the "Drive write cache" is the physical drive cache and the array accelerator is the controller cache.

Re: Array accelerator vs Drive Write Cache on P410i (DL580 G7)
In the facts, I don't want to active the drive write cache.
I lost a battery on my controller few days ago. After replace and charge the Array accelerator board, I suspect the server don't use the cache (low performance), so I tried to understand if the drive write cache is not implicated.
