[Disksim-users] Problem About the on-board Cache

[hust_mb]

Hi,
I am confused about the on-board cache in disk.  What I mean is not the cache in the controller but the on-board cache in disk.
For example the SEAGATE ST39102LW disk has 1MB on-board buffer while 840KB (also 4MB opertional will 3700KB used) is used for data caching as well as for speedmatching between the bus and the disk media. But the on board cache config parameters is only as a part of disk config. The flush policy and others parameters are not included. While in the reference manual the "3.4.9 Memory Caches" is only for the Controller type, isn't it?    

How can I config my on-board cache except the parameters that in the disk config (in the "3.4.5 Disks" Number of buffer segments, Enable caching in buffer and so on..). Such as flush policy as in the "Memory Caches".

Thank you very much!
