The derived values are averaged over a 5-minute period. For more
information about energy-related commands, see the commands reference.
You can also query power usage and data usage with the showsu
command. For more information, see the showsu description in the
Command-Line Interface User's Guide.
National Institute of Standards and Technology (NIST) SP 800-131A security
enablement
NIST SP 800-131A requires the use of cryptographic algorithms that have
security strengths of 112 bits to provide data security and data integrity for
secure data that is created in the cryptoperiod starting in 2014. The DS8880
is enabled for NIST SP 800-131A. Conformance with NIST SP 800-131A
depends on the use of appropriate prerequisite management software
versions and appropriate configuration of the DS8880 and other
network-related entities.
Storage pool striping (rotate capacity)
Storage pool striping is supported on the DS8000 series, providing
improved performance. The storage pool striping function stripes new
volumes across all arrays in a pool. The striped volume layout reduces
workload skew in the system without requiring manual tuning by a
storage administrator. This approach can increase performance with
minimal operator effort. With storage pool striping support, the system
automatically performs close to highest efficiency, which requires little or
no administration. The effectiveness of performance management tools is
also enhanced because imbalances tend to occur as isolated problems.
When performance administration is required, it is applied more precisely.
You can configure and manage storage pool striping by using the DS8000
Storage Management GUI, DS CLI, and DS Open API. The rotate capacity
allocation method (also referred to as rotate volumes) is an alternative
allocation method that tends to prefer volumes that are allocated to a
single managed array, and is not recommended. The rotate extents option
(storage pool striping) is designed to provide the best performance by
striping volumes across arrays in the pool. Existing volumes can be
reconfigured nondisruptively by using manual volume migration and
volume rebalance.
The storage pool striping function is provided with the DS8000 series at no
additional charge.
Performance statistics
You can use usage statistics to monitor your I/O activity. For example, you
can monitor how busy the I/O ports are and use that data to help manage
your SAN. For more information, see documentation about performance
monitoring in the DS8000 Storage Management GUI.
Sign-on support that uses Lightweight Directory Access Protocol (LDAP)
The DS8882F system provides support for both unified sign-on functions
(available through the DS8000 Storage Management GUI), and the ability
to specify an existing Lightweight Directory Access Protocol (LDAP) server.
The LDAP server can have existing users and user groups that can be used
for authentication on the DS8882F system.
Setting up unified sign-on support for the DS8882F system is achieved by
using IBM Copy Services Manager or IBM Spectrum Control. .
Note: Other supported user directory servers include IBM Directory Server
and Microsoft Active Directory.
