Smart array 5300 with cache 64MB

[Viviane]

Good afternoon to all! My friends, I am with a doubt, and would like to verify if some of you can help me removes it it. I am with one smart Array 5300 with one cache of 64MB, however in smart Array configuration utility, in settings of the controller, the part of Accelerator Ratio, where shows to the total memory available, is appearing only 48MB. Will be that some of you would know to say me because of this? Since already I am thankful.
