Appeal No. 2001-0462
Application 08/885,325
logical-physical addresses transformation will
take place). Since only the tracing of data
access requests are monitored without actually
accessing the data, and furthermore, even if a
physical data block needs to be transferred, a
logical to physical address translation/mapping
has to take place first, thus Akyurek clearly
teaches tracing of accesses at the logical file
access level.
We are persuaded by the examiner's reasoning taken with the
teachings and suggestions and reasonable inferences the artisan
would have made based upon the examiner's reliance upon topic 2
at pages 92-93 as they relate to Figure 1 in Akyürek. We, as
well as the examiner, do not agree with the appellants' initial
assertion at page 7 of the brief that Akyürek does not teach
monitoring be done at a logical level, and that tracing of
accesses is done at a physical disk block level rather than at a
logical file access level. The reference stream analyzer in
Figure 1, as correlated by the examiner, appears to us to perform
a monitoring or tracing function, to the extent broadly recited
in the claims on appeal, of logical blocks desired to be read
from or written to the disk shown in this figure. The Hot-Block
Table performs the mapping of these logical blocks of data to the
reserved space in the disk shown in this figure. As expressed at
the bottom of page 92 the "component labeled Hot-Block Table
contains a list of these blocks and their locations in the
