Power requirements for frames

A description of the power requirements for frames in the TS3500 tape library.

Table 1 lists the electrical characteristics for the TS3500 tape library frame models.

Leakage current 1 mA 8 mA maximum with 12 drive power supplies installed
Notes:
  1. Maximum certified electrical limits for a single frame. Nameplate limits should not be used to calculate product power or cooling requirements.
  2. Models HA1, SC1, S24, and S54 do not connect to external ac power.

Table 2 lists the power consumption of the TS3500 tape library models, power consuming features, and drive canisters.

Notes:
  1. These models come equipped with dual ac line cords. The figures in this table show the total power consumed, including power consumed by redundant power supplies. Each individual line cord supplies approximately half of the power.
  2. Frames with no frame control assembly (FCA) or enhanced FCA consume no power and require no cooling.
  3. S-frame power is for internal lighting and is provided by the power supplies in frames that are equipped with power.
  4. The HA1 frame is not connected to ac power. The power shown is the total consumed by the second accessor and is provided by the power supplies in frames that are equipped with power.
  5. Drive mounting kit power includes ac/dc conversion losses in drive power supplies (including redundant power), but does not include power consumed by the drive canister.
  6. Drive power includes the drive and canister cooling fan, but does not include power losses in external ac or dc drive power supplies. Idle power is consumed when the drive has no tape cartridge loaded. Maximum continuous power is consumed when the drive is actively writing to a tape cartridge.
  7. "Off" refers to power consumed when the library is connected to an ac power source and the library on/off switch is set to off.
  8. Model SC1 power is provided by the library frames to which it connects. The idle power is the power consumed by each shuttle station when no shuttle car is present. The maximum continuous power is the power consumed by the shuttle station when the shuttle car is present.

In order to calculate the total power consumption (in watts) of a particular library configuration, multiply the quantity of each power consuming item in the configuration by the corresponding value in Table 2 and calculate the 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 3 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.

  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.
