Appendix B. SAN Volume Controller physical installation
planning
Before the IBM service representative can set up your SAN Volume Controller
environment, you must verify that the prerequisite conditions for the SAN Volume
Controller, the uninterruptible power supply, and optional redundant ac-power
switch installation are met.
SAN Volume Controller 2145-CF8 environment requirements
Before the SAN Volume Controller 2145-CF8 is installed, the physical environment
must meet certain requirements. This includes verifying that adequate space is
available and that requirements for power and environmental conditions are met.
Input-voltage requirements
Ensure that your environment meets the following voltage requirements.
Voltage
Frequency
200 V to 240 V single phase ac
50 Hz or 60 Hz
Attention:
v
If the uninterruptible power supply is cascaded from another uninterruptible
power supply, the source uninterruptible power supply must have at least three
times the capacity per phase and the total harmonic distortion must be less than
5%.
v
The uninterruptible power supply also must have input voltage capture that has
a slew rate of no more than 3 Hz per second.
Maximum power requirements for each node
Ensure that your environment meets the following power requirements.
The maximum power that is required depends on the node type and the optional
features that are installed.
Table 5. Maximum power consumption
Components
Power requirements
SAN Volume Controller 2145-CF8 and 2145
UPS-1U
200 W
For each redundant ac-power switch, add 20 W to the power requirements.
For the high-speed SAS adapter with from one to four solid-state drives, add 50 W
to the power requirements.
Circuit breaker requirements
The 2145 UPS-1U has an integrated circuit breaker and does not require additional
protection.
