I am looking into the write performance and have a few questions on the cache. Hope someone may know the answer.
a. for the smart Array 5i Plus controller, and without BBWC, will there be any cache or memory on the controller?
b. I assume the answer for (a) is no. If so, how can we find out what is the allocation for read/write? will it be 50% for read and 50% for write? can it be changed?
thanks
Solved! Go to Solution.

SolutionFollowing are the answers for your queries.
A. smart Array 5i Plus controller has
64mb onboard memory(apart from the memory that you add on.)
B.To see the performance Read and Write.YOu could use Array configuration utility, Highlight the controller, then Use controller properties or statistics on the right hand side.A new window appears.Which would show you all the details.

Re: Cache on Smart Array 5i plus
With BBWC the cache is use for read and write cache.
If i remember correctly default is 50 / 50%
You can see and change that using the ACU

Re: Cache on Smart Array 5i plus
gregersenj,
does it mean that it is the *same* 64MB cache, but when I included BBWC, then the cache will become writable?
