Engineering

At NEXITIC we cover the following services

  • Conceptual design
    Previous studies and analyses, preliminary projects and conceptual projects.
  • Basic project
    The basic or schematic project, conceived as an advanced concept with a view to presentation and management before local authorities, is a first step before our clients, with whom a much more refined design advance is developed and closer to the final objective of the investment. .
  • execution project
    We conceive the execution project as a whole, because the Data Center is an organic system whose physical service infrastructure interacts in multiple directions and layers, due to the very condition of its high criticality and service.
  • BIM design
    NEXITIC can approach your designs under a BIM modeling tool; reconciled and linked to project management, BIM design allows cost analysis, precision in the work program, traceability and adjustment of modifications throughout the entire process, from the first conceptual phase to the final tests and “Black Building Test”.

NEXITIC covers the entire field of Data Center facilities infrastructure, covering its main areas of physical infrastructure:

Air conditioning

At NEXITIC we know the Data Center business in its multiple versions, so that our solutions cover physical modularity and scalable development, or IT growth and expansion of various types of IT services for different IT & DC business models, depending on whether it is Co-location, Hyperconvergence, Cloud, Edge Data Centers, Hosting services or Big Data, to name a few: one design strategy or another can then be approached and focused; Even in the case of Data Centers for corporate accommodation, the solutions to be implemented will be far from the usual ones. In chilled water systems, we carefully consider the suitability of constant or variable flow, depending on the hydraulic branches and required redundancy, but without ever forgetting the degree of energy efficiency, "continuous cooling" or the range of operating temperatures. .

The filtering index according to ISO standards and ASHRAE 62.1-2010- "Ventilation for Acceptable Indoor Air Quality" is another aspect that we look at carefully, as well as strict compliance with the most demanding standards that already constitute our know-how.

Design temperatures, the double temperature set-point for free-cooling water, the control strategy according to hot/cold aisles, or the application of overpressure or isothermal impulsion through the wall are some of the multiple approaches with which we approach our design, striving for excellence and the most optimal year-on-year PUE.

We analyze the pair formed by T/HR of the cold air before it enters the servers, according to the guidelines set by TC 9.9, and we even have "IT cooling" and "thermal management" analysts capable of focusing on the impact on the degree of computing and its efficiency depending on the average room temperatures. Our 360/holistic engineering ethos means that hardly anything is left out of plan.

electrical infrastructure

The electrical infrastructure and energy services is an essential field that NEXITIC approaches for its definition from diverse and concurrent points of view: without neglecting the aspect of energy efficiency itself, it looks above all for the achievement of robustness and resilience according to the TIER level or security rating:

  • Systems with double branches for conventional or open busbars.
  • Electrical design strategy according to redundancy level.
  • Intelligent PDU and distribution analysis in 19” rack and 21” rack.
  • ATS and STS.
  • Topology and typology of land networks such as TN-S.
  • State-of-the-art UPS systems.
  • Electrical panels for hot operation, type FORM 4 and other standards.
  • In-rack power distribution at 24 and 48V.
  • •Analysis of autonomy.
NEXITIC scrupulously analyzes the risks of single points of failure or SPOFs within the electrical topology designed to meet the most demanding TIER safety standards.
  • State-of-the-art generator sets and emergency systems.
  • Kinetic energy storage systems (KE Storage) type DRUPS.
  • • Analysis and selection of long-lasting batteries and greater autonomy (Lithium ion or VRLA).

fire protection systems

We design the most appropriate fire protection system, in accordance with national regulations and international standards.

  • Automatic extinguishing systems by chemical or inert means (N2+Ar), CO2 or NOVEC 1230. Protección contra incendios NEXITIC
  • Water mist extinguishing systems. Protección contra incendios NEXITIC
  • Early smoke detection systems by aspiration (VESDA). Protección contra incendios NEXITIC
  • Oxyreduction.
  • Overpressure systems and action on the service infrastructure (HVAC, others), without affecting the continuity of the service.
  • Passive protection systems and analysis of sectorization, fire load and intrinsic risk.
  • On request, modeling of fire development with FDS software is possible.
NEXITIC designs and projects from each application code or specific regulation: UNE, NFPA, FM, BS.

mechanical services

  • Plumbing systems and general sanitation of the building, looking for the most optimal and safe system, always considering the particularities and singularities of a Data Center.
  • Studies for capture and collection of rainwater, and supply to tertiary systems.
  • Sewage treatment.
  • Fuel transfer systems.
  • Treatment of purge, condensation and drainage water through reverse osmosis and post-treatment.

  • Advice and design for compliance with LEED requirements. “water efficiency” and “water use reduction”.

Regulation, BMS and DCIM

DCIM, for years the intelligent paradigm for the control and management of the Data Center, is a matter of analysis, selection and design by our experts. DCIM and BMS converge in the Data Center in order to provide clean rooms with greater autonomy, control capacity, resilience, transparency, monitoring and energy efficiency. DCIM and BMS are the physical infrastructure and server monitoring tools, for whose implementation, combining with virtualization, load balancing strategies, rotation, exploitation peaks, O&M, etc... has become one of the cornerstones, and for this reason NEXITIC looks at and coordinates the best solution for the Data Center with the main market providers.

Combining it with the field of consulting and O&M;, DCIM is not only the software tool capable of managing energy, IT operation and alarm status within the Data Center, but it must also have the capacity and vision to: provide the elements and criteria for the assessment and planning of the life cycle of assets, the capacity for change, migrations and, in general, all the aspects where the peculiarities of O&M converge; of the infrastructure with its own software and IT operation services.

Communications and networks

According to the type of Data Center (Multi-vendor Carrier Neutral, low latency, etc…) and the degree of redundancy and resilience, we project the best communications and network system for the data center, according to:
  • Communications infrastructure. Single-mode and multimode fiber optic network for Data Center interconnection and campus networks.
  • Own local network infrastructure: network electronics, wireless environments and structured cabling.

Intrinsic security, access control and video surveillance

The physical security of the Data Center has always been, and is becoming more and more so, an essential requirement for the full control and good operation of the data center: from both aspects (the security of protection against negligence/attack, and that of the security against natural disasters) the Data Center complex designed by NEXITIC always satisfies both demands, reconciling them with the rest of the requirements that are part of the usual access control and video surveillance operations, at different levels according to authority and field of performance.

SEGURIDAD INTRÍNSECA, CONTROL DE ACCESOS Y VIDEOVIGILANCIA

Electronic security and access control play a special and complex role in the logistics of the entry of goods and people in a Data Center. We design the spaces and their accessibility and easement steps from the origin, contemplating the interaction and affectation of access control and the corresponding video surveillance and biometric control.
SEGURIDAD INTRÍNSECA, CONTROL DE ACCESOS Y VIDEOVIGILANCIA

For this we design the systems related to:
  • Video surveillance
  • Access control
  • Intrusion
  • CHALK
  • Capacity Control
  • Intercom
