VTSS Configuration Planning
■ VTSS Configuration Planning
A VSM5 system consists of Virtual Tape Control System (VTCS) host software, Virtual
Tape Storage Subsystem (VTSS) disk hardware (tape buffers)
1
, real tape drives (RTDs)
which attach to an Automated Cartridge System (ACS), and automated cartridge systems
(ACSs), a.k.a. tape libraries.
A VSM5-VTSS connects to IBM S/390-equivalent data-streaming architectures and relat-
ed hardware
2
, and has front-end and back-end FICON connections. ESCON connections
are not available for VSM5-VTSS.
VSM5-VTSS Environmental Requirements
VSM5-VTSS Physical Characteristics
1. Both a primary VTSS and secondary VTSS can be used within a single system configuration.
2. Including, but not limited to: OS/390, z/OS, MVS, and VM host systems and FICON directors (switches) by Brocade, CNT, and
McData. Check with Sun product marketing for the latest certification and compatibility information for VSM systems.
