Corrosive gasses and particulates
Plan for air quality that meets standards for corrosive gases and particulates.
The DS8000 is designed to operate reliably in a General Business class
environment. A General Business class environment is one that has automated
24x7x365 temperature and humidity controls and also operates with the following
specifications for corrosive gases and particulates: G1 for corrosive gases, P1 for
particulates.
Operating vibration requirements
The vibration levels designed for the DS8700 and DS8800 comply with class V1
requirements included in the product classes for vibration.
The DS8700 and DS8800 are designed to operate under the vibration V1 levels
described in Table 65.

Contamination information
You must consider the air quality and contamination levels at your installation site.
Airborne particulates (including metal flakes or particles) and reactive gases acting
alone or in combination with other environmental factors, such as humidity or
temperature, might pose a risk to the IBM System Storage DS8000 hardware. Risks
that are posed by the presence of excessive particulate levels or concentrations of
harmful gases include damage that might cause the DS8000 to malfunction or
cease functioning altogether. This specification presents limits for particulates and
gases that are intended to avoid such damage. The limits must not be viewed or
used as definitive limits because numerous other factors, such as temperature or
moisture content of the air, can influence the impact of particulates or
environmental corrosives and gaseous contaminant transfer.
Attention: In the absence of specific limits that are presented in this document,
you must implement practices that maintain particulate or gas levels that are
consistent with the protection of human health and safety. If IBM determines that
the levels of particulates or gases in your environment have damaged the DS8000,
the warranty is void. Implementation of correctional measures is a customer
responsibility.
The following criteria must be met:
Gaseous contamination

, which states that the
reactivity rate of copper coupons must be less than 300 Angstroms per
month (Å/month, ≈ 0.0039 µg/cm2-hour weight gain)
