Certified Data Centre Specialist

Overview

CDCS® (Certified Data Centre Specialist) is a 3-day advance level for training data centre design/build professionals.  The CDCS® course will cover engineering calculations on the various components in a data centre facility.  CDCS® will further increase attendees’ competences to a level of a compatible sparring partner with suppliers and verify offers provided by vendors for correctness, effectiveness and efficiency.

CDCS® is the second training in the EPI Design and Build training track under the EPI Data Centre Training Framework. Participants must hold a valid CDCP® certificate in order to be able to register for the CDCS® class. CDCS itself is a pre-requisite for persons wishing to achieve the CDCE® status.

Audience Profile

The primary audience for this course is an IT, Facilities or Data Centre Operations professional working in and around the data centre (representing both end-customers and/or service provider/facilitators) and having responsibility to achieve and improve high availability and manageability of the Data Centre, such as: Data centre managers, Operations / Floor / Facility managers, data centre engineers, network/system engineers, data centre sales/consultants.

Prerequisites

Participants must hold a valid CDCP® certificate in order to be able to register for the CDCS® class.

Exam: Certified Data Centre Specialist (CDCS®)

Attendees will take a 1.5 hour CDCS® exam. The exam is 60 questions, multiple choice, closed-book. The passing mark is 45 out of 60.

Attendees passing the exam will be awarded the internationally accredited and recognized ‘Certified Data Centre Specialist’ certificate (CDCS®).

CDCS® is globally accredited by EXIN, a fully independent exam and certification institute. The CDCS® certificate is valid for 3 years, after which recertification is required.
