  Data Compression Transfer Log Page (39h) (Sony Unique) 

The page allows the initiator to monitor the performance of the ALDC compression. The PC field in LOG SENSE 

determines whether current cumulative or current/default threshold values are returned. The page has the 

following format:

Entities Written/Read:

 The total number of complete entities written to or read from the tape since the last 

power-on or Clear Log operation. 

Records Written/Read:

 The total number of records (both compressed and uncompressed) written to or read 

from the tape since the last power-on or Clear Log operation. 

Kilobytes to/from Data Compression:

 The total number of kilobytes written to or read from the tape since the 

last power-on or Clear Log operation. For Kilobytes from Data Compression, this number may be greater than the 

number of kilobytes transferred to the initiator due to read ahead. 

Logical Entity Size:

 The logical size of the last entity written to or read from the tape: size = number of record in 

entity 

×

 record size in bytes 

Physical Entity Size:

 The physical size of the last entity written to or read from the tape: size = entity header 

uncompressed data length 

Uncompressed Entities:

 The total number of times non-ALDC entities have been encountered on the tape during 

read operations since the last power-on or Clear Log operation.
