A data center (or datacenter) is a facility composed of networked computers and storage that businesses or other organizations use to organize, process, store and disseminate large amounts of data. A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations.
Data center infrastructure services include network hardware, servers, storage and security products. Each product includes hardware components and software to run the hardware. Find out the extent of each candidate's infrastructure knowledge. An understanding of end-to-end technology provides a good foundation for data center oversight.
There are many DCIM tools and suites of solutions on the market, and as with any acquisition, you need to look at each critically and choose the one that best meets your specific needs.
Application management tools are used to monitor technology services in the data center, along with facility services like humidity levels, cooling and power. Determine how well each candidate's experience corresponds to the tools currently used.
Taking a process-based approach to operations management keeps data center services predictable and reliable. Find out what approach each candidate has used. One common answer to expect is Information Technology Infrastructure Library (ITIL).
A cross connection is most often a layer 1 or physical layer connection between two networks. Data center providers typically segment cross connections by type of cabling used to make the connection - copper, coaxial or fiber. Cross connections are usually completed by the data center provider for a non-recurring (NRC) and a monthly recurring (MRC) charge.
Find out how many years the candidate has been working with data center services and what positions he's held. A director should have worked his way up, typically starting with an IT engineer role and progressing into management. Progressive experience provides keen insight into data center operations.
Metrics show business leaders how well things are performing and where attention is needed. Data center metrics provide performance values to gauge technology performance, such as the speed of the network. Find out how candidates select, collect and monitor metrics associated with data center performance.
Data center architecture is the physical and logical layout of the resources and equipment within a data center facility.
It serves as a blueprint for designing and deploying a data center facility. It is a layered process which provides architectural guidelines in data center development.
This is a very common question that is asked in almost every interview. I love this question because it gives you the opportunity to sell yourself. Discuss what makes you standout from the crowd and show them how you can help advance their company. Remember to be specific. This is where all the company research you have done comes into play. You should have an idea as to why the company is hiring or looking to hire someone for that position. What problem do they have that they are looking for people to help them solve? And once you can establish this, you are to show them how you can solve this problem for them.
