There are 2 kinds of compression. The outboard kind that takes place in the tape unit is one example. there is no difference in the z.os cpu time for writing a compressed tape.
the operating system kind which is always software. the software compression can be either just software or hardware assisted software. the case for SMS is that it is hardware assisted software. this means that the cpu used is much less than normal software compression but it does affect z.os cpu time. -- Mike ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
