IHS Markit is your source for the DCOS from EPI.
Until now, organisations delivering data centre services focus on building highly resilient facilities by designing redundancy at various levels typically in accordance with standards such as ANSI/TIA-942, ANSI/BICSI-002 and others. However, many organisations have come to realise that without having adequate processes and maintenance programs, the availability levels would be seriously impacted and "erode" the investment made in the data centre facility.
The DCOS® has been written to provide organisations with a structured and progressive approach to improve data centre operations management ensuring that the investment in the data centre is safe-guarded. Implementing DCOS® will enable the organisation to deliver services which are well defined and have a consistent level of quality. This standard is the first and only standard available in the market addressing all data centre operations and maintenance requirements.
