Data centers are essential for traffic, processing and storage of information
- Where: Size and number of data processing / storage equipment to be housed.
- How: Physical location, weather conditions and access.
- Robustness: Level of redundancy against computer, electrical and mechanical failures.
- Resources: Amount of cooling, energy needs, type of wiring.
- Security: Rigorous internal and external access control.
Systems in a data center
The solutions developed by ETICSA for data center infrastructure are based on the design considerations and components of the ANSI / TIA / EIA-942 standard, which are summarized in:
Air conditioning (HVAC)
Distribution (Boards, Wiring)
Generation (Generating Set)
Energy Backup Units (UPS)
EPO (Emergency Power Off)
Wiring System (Copper and Fiber)
TOPOLOGY FOR A DATA CENTER
A Data Center requires a dedicated space, which depending on its size could be divided into:
- Entrance (Entrance Room (EA)).
- Central Distribution Area (Main Distribution Area (MDA)).
- Horizontal Distribution Area (HDA).
- Zone Distribution Area (ZDA).
- Equipment Distribution Area (EDA).
CLASSIFICATION OF A DATA CENTER ACCORDING TO AVAILABILITY (TIERS)
TIER I: BASIC
Design data center of the basic type, susceptible to failures. Minimum capacity level for energy distribution and cooling, but there is no redundancy. Total loss of function in case of failure or maintenance.
TIER II: REDUNDANT COMPONENTS
Tier 2 datacenter with redundant components, less susceptible to disruptions, planned or not. It has a technical floor, UPS and generators. There is talk of N + 1 redundancy for UPS, but the system has only one distribution path.
TIER III : CONCURRENT MAINTENANCE
In this case, datacenter Tier 3, any planned activity of the datacenter infrastructure is allowed, without the interruption of the hardware operation. These activities can be preventive, scheduled maintenance, repair and replacement of components, addition or removal of components, testing, etc. All systems have N + 1 redundancy, but only one active path.
TIER IV: TOLERANT TO FAILURES
These data centers allow any planned activity without interruption to the critical load. For this, simultaneous trajectories are designed, that is, two separate UPS systems each with N + 1 redundancy.
