IBM Virtualization Engine TS7700 Series Statistical Data Format: Version 1.6

The IBM Total Storage 3494 Virtual Tape Server (VTS) revolutionized the way zSeries customers utilized their tape resources. To help the customer monitor the performance of the VTS various statistics were developed. These statistics appeared in two forms, hourly records sent to the hosts known as SMF94 records and periodic real-time statistics available via the Library's web specialist or in an XML file for use by the Total Productivity Center (TPC). For the next generation of VTS, the TS7700 Virtualization Engine, the statistics design has been revisited. The useful statistics from the VTS have been retained and new statistics relevant for the TS7700 have been added. Also, both Point-In-Time (PIT) and historical statistics are recorded.
