IBM System Storage TS3500 Tape Library with ALMS: Introduction and Planning Guide
total. In order to calculate the total cooling required by the library (in Btu/hr),
multiply the total power in watts by 3.4. To convert Btu/hr to kBtu/hr, divide
your result by 1000.
Table 45 provides a sample calculation of total power and cooling requirements for
a TS3500 Tape Library configuration consisting of one L23 with ten TS1130 tape
drives and mounting kits, four D23 models each containing six TS1130 tape drives
and mounting kits, one D23 with no drives or enhanced FCA feature (FC 1451),
two S24 models, and one HA1 model.

1. FC 1515: Tape drive mounting kit for L23 and D23 frames.
2. FC 1451: Enhanced frame control assembly for D23 and D53 frames.
Library power consumption is dynamic and usage dependent. Short peaks might
exceed the maximum continuous power values. Typical average power
consumption is lower than the calculated maximum continuous value because all
drives are not likely to be active simultaneously.
