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.

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. So a lot really depends on what you are trying to eliminate. Any of these would allow you to consolidate and fully utilize the new higher-capacity drives. If you are also trying to eliminate the number of physical drives you use; then a true virtual-tape emulation will be needed. That would either by an IBM VTS, Sun/STK VSM, CA-Vtape, the EMC Copycross or a few others. Most require some specific hardward purchase, but EMC will work if you already have an EMC dasd device and CA-Vtape will work with any dasd devices.

We are going to replace our tape hardware (Tape Library (ATL), VTS). In investigating how our "other operating systems" use tapes I found that they use IBM TSM to talk directly to the ATL - and get high tape utilization (i.e. stacking multiple files on tape). kind of like a software VTS. Is there a product that supports this function on z/OS? ---------------------------------------------------------------------- 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 No virus found in this incoming message.
