• The z/OS Distribute Data backup feature is disabled on all DS8000 systems in the environment
(local and remote sites).
• Thin provisioned volumes (ESE or TSE) are not used on any DS8000 systems in the environment
(local and remote sites).
• On zSeries systems there is only one tenant running in an LPAR, and the volume access is controlled
so that a CKD base volume or alias volume is only accessible by a single tenant’s LPAR or LPARs.
Restriction of hazardous substances (RoHS)
The DS8900F system meets RoHS requirements. It conforms to the following EC directives:
• Directive 2011/65/EU of the European Parliament and of the Council of 8 June 2011 on the
restriction of the use of certain hazardous substances in electrical and electronic equipment. It has
been demonstrated that the requirements specied in Article 4 have been met.
• EN 50581:2012 technical documentation for the assessment of electrical and electronic products
with respect to the restriction of hazardous substances.
Logical conguration
You can use either the DS8000 Storage Management GUI or the DS CLI to congure storage. Although the
end result of storage conguration is similar, each interface has specic terminology, concepts and
procedures.
Note: LSS is synonymous with logical control unit (LCU) and subsystem identication (SSID).
Logical conguration with DS8000 Storage Management GUI
Before you congure your storage system, it is important to understand the storage concepts and
sequence of system conguration.
Figure 2 on page 12
illustrates the concepts of conguration.
Figure 2. Logical conguration sequence
The following concepts are used in storage conguration.
