Datacenter a dedicated space within a building, or a group of buildings used to house computer
systems and associated components, such as telecommunications and storage systems.
In-house Datacenter Setup Checklist-
The assessment is done on the basis of following factors: - How many servers are expected to be placed in the DC.
- What would be the growth rate of these servers.
- Data holding capacity of these servers.
- How many users will be accessing the servers from the DC.
- Nature of Users accessing the servers from the DC.
Tier-2: A tier-2 data center setup has two UPS systems that run in parallel to ensure redundancy. So if one fails, the other takes over.
Tier-3: This setup has three UPS systems to help the organization ensure redundancy and concurrent maintainability. It requires at least n+1 redundancy, that is, when one path is running, the other is redundant.
Tier-4: This setup has four UPS systems to assure concurrent maintainability and fault tolerance. In addition to redundancy that is on the supply front, right from the first point of upstream; you need to have two sets of input power: two DGs, four UPS systems. (2+1 is the fault tolerant and n+1 is the redundant UPS which is concurrently maintainable).
- Enough space should be available in the front and back of the rack for the support engineers to work.
- Place UPS systems away from the server room to protect it from the electromagnetic field.
- Reduntent cooling system in the DC room
A Data Center Hardware Overview
A data center is a facility that houses hardware pertaining to data storage, processing and transfer. A regular data center contains hardware units catering to the computing, data storage and networking needs of the system. They are designed to centralize data processing and keep processes running with as little downtime as possible.
