Data Centre

Introduction

A data center requires significant infrastructure to support the center’s IT hardware. These include power subsystems, uninterruptible power supplies (UPS), ventilation, cooling systems, fire suppression, backup generators, and connections to external networks.

Design standards for a data center infrastructure

The most widely adopted standard for data center design and data center infrastructure is ANSI/TIA-942. It includes standards for ANSI/TIA-942-ready certification, which ensures compliance with one of four categories of data center tiers rated for levels of redundancy and fault tolerance.

Tier 1: Basic site infrastructure. A Tier 1 data center offers limited protection against physical events. It has single-capacity components and a single, nonredundant distribution path.

Tier 2: Redundant-capacity component site infrastructure. This data center offers improved protection against physical events. It has redundant-capacity components and a single, nonredundant distribution path.

Tier 3: Concurrently maintainable site infrastructure. This data center protects against virtually all physical events, providing redundant-capacity components and multiple independent distribution paths. Each component can be removed or replaced without disrupting services to end users.

Tier 4: Fault-tolerant site infrastructure. This data center provides the highest levels of fault tolerance and redundancy. Redundant-capacity components and multiple independent distribution paths enable concurrent maintainability and one fault anywhere in the installation without causing downtime.

Datacenter Operation:

Data center operations is a broad term that includes all processes and operations performed within a data center. Typically, data center operations are distributed across several categories such as:

Infrastructure Operations: Installing, maintaining, monitoring, patching and updating server, storage and network resources.

Security: Processes, tools and technologies that ensure physical and logical security in the data center premises

Power and cooling: All processes that ensure enough power is supplied to the data center facility and the cooling system is operational

Management: Creation, enforcement and monitoring of policies and procedures within data center processes
