As Timothy stated, there are may options. Some (CA-1/Copycat, TLMS/Copycat, Tivoli Tape Optimizer, TAPESAVER, FATSCOPY) will copy tapes files AFTER they have been created and stack them together. CA-Vtape is a true virtual-tape emulation that uses existing dasd as the cache and then stacks the copies on the backend high-capacity cartridges.

Is there a product that supports this function on z/OS? Apples and oranges. Similar, but different. TSM is an *application* using *real* tapes in efficient way. The closest comparison to TSM is DFSMSHSM or FDR/ABR. However that means you should write directly to your tape, no DD names pointing to tape datasets. While it's quite good idea, it could require changes in your processing. On the other hand, VTS, VSM and some other solutions do similar thing on hardware side, thus (almost) no changes are required on software side. There are also some products which 'fill the gap' - those product TRY to optimize media utilization with minimal changes to current job processing. IMHO it is better to change current processing than spend money on products which partially solve the problem.

Re: Software only VTS?
John, If a licence to enable DFSMShsm, ABR, or install similar software is required then I would have to agree with you. I've only ever seen one Production LPAR that was not running a migration product... but they were for it anyway. Ron --- snip -- That's almost true Ron. Some product has to move the data to tape.

Is there a product that supports this function on z/OS? If the goal is to get higher tape utilization, there are many ways to do that. Tape stacking is one good way, and there are many such products. One example is IBM Tivoli Tape Optimizer for z/OS: http://www-306.ibm.com/software/tivoli/products/tape-optimizer-zos/ And there are many other products in this general category. Here are some that might be applicable: CA - BrightStor CA-Vtape CA - BrightStor CA-1 CopyCat UNICOM - CARTS/TS OpenTech - Tape/Copy Innovation Data Processing - FATSCOPY BetaSystems - Beta 55 Storage Optimization Manager SEA - ZELA Tape Stacking Cartagena Software - TelTape/390 There have been a lot of discussions in the IBM-MAIN archives about hardware VTSes and when they have value. That's probably worth some study. It could very well be that hardware VTS is the way to go. Also, I couldn't quite tell if you know about Tivoli Storage Manager for z/OS. Sounds like it, but just mentioning it. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] -- 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

Is there a product that supports this function on z/OS? TSM is primarily a backup/archive utility. Under z/OS those functions are handled primarily by products like HSM or FDR/ABR. I'm not sure about HSM, but ABR does an excellent job of filling up tapes. -- Tom Marchant -- 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

Re: Software only VTS?
Afaik Control-T has the ability to stack files on tapes in order to optimize/utilize tape space. You probably do not want to mount tape all day to copy files from one tape to another and do only one write on the proper tape. You should use a tape library product like CTT, but I am sure this is not the only one in market that does that. Other option is to use cheap (read SATA) disk arrays with an emulation control unit that mimics 3390. There are some players in this market like Bustech.
