When you are planning to meet the power requirements for the DS8A00 series, consider the
power consumption and other environmental points of the storage system.
The power consumption and environmental information for the DS8A00 is provided in
Table 1.

Notes:
- The values represent data obtained from typical systems, which are configured as follows:
- Model A01, A05, or E05 that contains four fully configured High Performance
Flash Enclosure Gen3 pair and 16 Fibre Channel adapters.
- All frames and configurations that are used in single-phase mode must not exceed 8 kVA.

Notes:
- Declared level LWA,m is the mean A-weighted sound power level.
- Declared level LpA,m is the mean A-weighted sound pressure level computed as the
arithmetic average of the measurements at the 1-meter bystander positions, or it is measured as the
maximum 0.5-meter operator position at the front or rear face with the doors opened.
- The statistical adder for verification, Kv, is a quantity to be added to the declared
mean A-weighted sound power level, LWA,m such that there will be a 95% probability of
acceptance, when using the verification procedures of ISO 9296, if no more than 6.5% of the batch of
new equipment has A-weighted sound power levels greater than (LWA,m + Kv).
- The quantity LWA,c (formerly called LWAd), can be computed from the sum of
LWA,m and Kv.
- Measurements are made in conformance with ISO 7779 and declared in conformance with ISO
9296.
- B, dB, abbreviations for bels and decibels, respectively. 1 B = 10 dB.
- Under certain environments, configurations, system settings and/or workloads, fan speeds are
increased resulting in higher noise levels.
Notice: Government regulations (such as those prescribed by OSHA or European Community
Directives) may govern noise level exposure in the workplace and may apply to you and your server
installation. The actual sound pressure levels in your installation depend upon a variety of
factors, including the number of racks in the installation; the size, materials, and configuration
of the room where you designate the racks to be installed; the noise levels from other equipment;
the room ambient temperature, and employees' location in relation to the equipment. Further,
compliance with such government regulations also depends upon a variety of additional factors,
including the duration of employees' exposure and whether employees wear hearing protection. IBM
recommends that you consult with qualified experts in this field to determine whether you are in
compliance with the applicable regulations.
