• Particulate contamination
Attention: Airborne particulates and reactive gases acting alone or in combination
with other environmental factors such as humidity or temperature might pose a risk to
the server. For information about the limits for particulates and gases see
“Particulate contamination” in ThinkSystem SR850 Maintenance Manual.
Operating systems
Supported and certified operating systems:
• Microsoft Windows Server
• VMware ESXi
• Red Hat Enterprise Linux
• SUSE Linux Enterprise Server
References:
• Complete list of available operating systems: https://lenovopress.lenovo.com/osig.
• OS deployment instructions: “Deploy the operating system” on page 126.
Note: To maintain component reliability system performance might vary at ambient temperature higher than
35°C while all the fans are functioning. With one fan failing system performance might vary at ambient
temperature higher than 27°C.
Particulate contamination
Attention: 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
device that is described in this document.
Risks that are posed by the presence of excessive particulate levels or concentrations of harmful gases
include damage that might cause the device to malfunction or cease functioning altogether. This
specification sets forth 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
Chapter 1.Introduction 7

moisture content of the air can influence the impact of particulates or environmental corrosives and gaseous
contaminant transfer. In the absence of specific limits that are set forth in this document you must
implement practices that maintain particulate and gas levels that are consistent with the protection of human
health and safety. If Lenovo determines that the levels of particulates or gases in your environment have
caused damage to the device Lenovo may condition provision of repair or replacement of devices or parts
on implementation of appropriate remedial measures to mitigate such environmental contamination.
Implementation of such remedial measures is a customer responsibility.
Table 2. Limits or particulates and gases
Contaminant imits
Reactive gases Severity level G1 as per ANSI/ISA 71.04-19851:
• The copper reactivity level shall be less than 200 Angstroms per month (Å/month ≈ 0.0035 μg/
cm2-hour weight gain).2
• The silver reactivity level shall be less than 200 Angstroms per month (Å/month ≈ 0.0035 μg/
cm2-hour weight gain).3
• The reactive monitoring of gaseous corrosivity must be conducted approximately 5 cm (2 in.) in
front of the rack on the air inlet side at one-quarter and three-quarter frame height off the floor
or where the air velocity is much higher.
Airborne
particulates Data centers must meet the cleanliness level of ISO 14644-1 class 8.
For data centers without airside economizer the ISO 14644-1 class 8 cleanliness might be met by
choosing one of the following filtration methods:
• The room air might be continuously filtered with MERV 8 filters.
• Air entering a data center might be filtered with MERV 11 or preferably MERV 13 filters.
For data centers with airside economizers the choice of filters to achieve ISO class 8 cleanliness
depends on the specific conditions present at that data center.
• The deliquescent relative humidity of the particulate contamination should be more than 60%
RH.4
• Data centers must be free of zinc whiskers.5
1 ANSI/ISA-71.04-1985. Environmental conditions or process measurement and control systems: Airborne
contaminants. Instrument Society of America Research Triangle Park North Carolina U.S.A.
2 The derivation of the equivalence between the rate of copper corrosion growth in the thickness of the corrosion
product in Å/month and the rate of weight gain assumes that Cu2S and Cu2O grow in equal proportions.
3 The derivation of the equivalence between the rate of silver corrosion growth in the thickness of the corrosion
product in Å/month and the rate of weight gain assumes that Ag2S is the only corrosion product.
4 The deliquescent relative humidity of particulate contamination is the relative humidity at which the dust absorbs
enough water to become wet and promote ionic conduction.
5 Surface debris is randomly collected from 10 areas of the data center on a 1.5 cm diameter disk of sticky
electrically conductive tape on a metal stub. If examination of the sticky tape in a scanning electron microscope
reveals no zinc whiskers the data center is considered free of zinc whiskers.
