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.

AVSM5-VTSS connects to IBM S/390-equivalent data-streaming architectures and relat- ed hardware2, and has front-end and back-end FICON connections. ESCON connections are not available for VSM5-VTSS.

VSM5-VTSS Environmental Requirements

Table 2-2. VSM5-VTSS Environmental Requirements

Environmental	Shipping Environment	Storage Environment	Operating Environment
Factor	Limits*	Limits#	Limits
Temperature	-40oC to +60oC	10oC to 40 C	16oC to 32oC
	(-40oF to +140o F)	(50o F to 104o F)	(60o F to 90o F)
Thermal Change	15 C	15oC	5oC
(maximum rate/hr)	(27o F)	(27o F)	(9o F)
Humidity‡	10% to 80%	10% to 80%	20% to 80%
Altitude	0m to 15,240m	0m to 3050m	0m to 2439m
	(0 ft. to 50,000 ft.)	(0 ft. to 10,000 ft.)	(0 ft. to 8000 ft.)

Notes:

• Abbreviations key: C = Centigrade; F = Fahrenheit; ft. = foot / feet; m = meter(s)

• * The shipping environment must not exceed the storage environment limits longer than 10 days.

• # The storage environment must not exceed the operating environment limits longer than 60 days.

• ‡ Humidity specifications exclude conditions that may cause condensation on disk drives.
