Course Details
Course Code: CDCS; Duration: 3 Days; Instructor-led
With few exceptions, enterprises today rely on IT for the delivery of business-critical services – often directly to the end consumer. It is therefore vital that the mission critical data Centre is designed, maintained and operated with hi-availability and effi¬ciency in mind. Fact is however that most data Centre’s do not meet the full availability, capacity, safety or e¬fficiency requirements often demanded.
CDCS® will further increase attendees to a level being a compatible sparring partner with suppliers and they will be able to verify offers provided by vendors for correctness, e effectiveness and effi-ciency. CDCS® is a must have certification for professional data Centre managers and Personnel. CDCS® is a pre-requisite for individuals wishing to achieve the CDCE® status.
Audience
The primary audience for this course is an IT, facilities or Data Centre Operations professional working in and around the data Centre and having the responsibility to achieve and improve hi-availability and manageability of the Data Centre.
Prerequisites
Participants must hold a valid CDCP® certificate in order to be able to register for the CDCS® class.
Methodology
This program will be conducted with interactive lectures, PowerPoint presentations, discussions and practical exercises
