In order for management policies and procedures to be effective,
training on the policies and procedures is fundamental. An emphasis
within the standard is to ensure all personnel are skilled, qualified,
trained and competent in the tasks they are required to perform.
This requires ongoing training and verification of understanding
the specific unique operating practices, policies and procedures
implemented in the data center where they are performing those tasks.
BICSI CLASSIFICATIONS AND OPERATIONS
Within ANSI/BICSI 002, there are 5 classes defined
for various levels of redundancy:
Class-0 Single path that does not meet all the
requirements of Class-1 or higher
Class-1 Single path with no redundancy
Class-2 Single path with component redundancy
for components with high failure rates
Class-3 Concurrently maintainable
Class-4 Concurrently maintainable
and fault tolerant
When developing the BICSI 009 standard, it was important to identify
how the various BICSI classes impacted operations.
Standard Operating Procedures
A data center’s standard operating procedures address standards for care
and quality of work, which are typically the same across all BICSI classes.
Maintenance Operating Procedures
When conducting maintenance tasks on a BICSI Class-0, Class-1, or
a non-redundant component or system in a Class-2 data center, a planned
outage is required. If there is a failure in completing the maintenance
task as anticipated, the outage will likely extend beyond the scheduled
time frame.
When conducting maintenance tasks on a BICSI Class-3, Class-4, or
on redundant components or systems in a Class-2 data center, a planned
outage is not required. If there is a failure in completing the maintenance
task, an unplanned outage could occur if the failure cascaded to the
redundant or other components and systems intended to support the
ongoing IT operations.
