What allowances does SmartProduction make for Virtual Tape environments?
SmartProduction includes various cases for cartridge and tape devices, including Virtual Tape Systems (VTS). For example, the following issues are addressed for VTS: – Over-allocation of drives: Each VTS has a fixed number of virtual tape drives. During peak hours, jobs requiring a tape drive may be delayed when there is no free tape drive available. Therefore, it is important to ensure that each job using the VTS allocates only the number of tape drives required. – Operational delays: For example, when two jobs request the same tape volume serial number, the operating system will delay one of them. – Inefficient I/O: slow access mode, non-optimal blocksizes. back to FAQ 21.
