StorageTek SL3000 Library Guide
■
Power consumption: 1,771W x 3.412 = 6,043 Btu/hr
Cooling
Cooling within the SL3000 library is divided into three areas:
■
Electronics control module
■
Tape drives
■
DC power supplies
Library Electronics Control Module
Two fans, located to the right of the electronics control module, provide cooling for the
electronics in the library. Air is drawn from the sides of the library and flows through
the fans to the rear of the library.
■
The library controller card (HBCR) monitors these fans for proper operation.
■
The amber Fault indicator on the fan assembly indicates a failure.
While there are two dedicated fans, one fan is sufficient to provide adequate cooling
for the library and the electronics. The fans can be replaced without interfering with
library operations. Replace a defective fan when it is detected.
Tape Drives
Each tape drive tray contains a fan for drive cooling. The tape drive's power converter
card supplies power for the fans. Air is drawn from the front of the drive and flows
through the fan to the rear of the drive/library.
DC Power Supplies
Each 1200 Watt DC power supply contains a fan that pulls air from the library, through
the rear of the supply, and out the rear of the library.
Storage Capacity
There are two types of capacity:
■
Physical Capacity — the number of cartridge slots in the library, excluding
reserved slots. Physical storage capacity can range from 205 to 5,925 data cartridge
slots and 1 to 56 tape drives.
■
Active Capacity — the number of slots in the library activated by a hardware
activation file. Only activated slots can be used for data storage and accessed by a
client. Inactivated slots are not recognized by the library.
A diagram of the slot locations within each module can be helpful for understanding
capacity (for wall maps, see
"Library Addressing Reference"
Note:
Oracle recommends adding physical capacity in advance to
meet future storage needs. Although modules can be added to an
SL3000 library at any time, adding a module is disruptive to library
operations.
