From electrical load study to commissioning, Sidouni Technologie designs and builds the complete infrastructure — electrical redundancy, precision cooling, high-density cabling, physical security and monitoring — for facilities where downtime is not an option.
What truly sets a data centre apart
A poorly designed data centre does not fail at handover. It fails six months later, when the real load exceeds what was planned, when a Sonelgaz outage reveals that the generator was never load-tested, or when the room temperature climbs because cooling was sized per square metre instead of per watt of heat dissipated.
What we deliver:
Dual-path supply, UPS units sized on the real IT load, generator with automatic changeover, distribution boards dedicated to the server room. In Algeria this is not optional. It is the answer to the reality of the Sonelgaz grid.
Fine control of temperature (18-27°C) and humidity (45-60% RH) to ASHRAE standards. Sized on the actual heat load of the installed equipment, not on the floor area. Standard comfort cooling in a server room is an overheating waiting to happen.
19" racks with cable-tray management, physical separation of power and data runs, a category matched to the required throughput, and an organisation designed for maintenance and future growth, not just for delivery day.
Biometric or badge access control to the server room, CCTV compliant with decree 09-410, addressable fire detection suited to sensitive electronic environments, with gas suppression where the criticality level justifies it.
Real-time monitoring of temperature, humidity, power supply and physical access. Threshold-based alerts with SMS or e-mail notification. A data centre without monitoring is a system whose failures you learn about after the fact.
Redundancy standards
The Uptime Institute defines four redundancy levels (Tier I to IV) matching measurable availability rates, from 99.67% to 99.999%. Many Algerian facilities end up with a Tier I data centre built without redundancy, while the services they host would require at least Tier II.
In practice, for an Algerian institution:
A single power path, no active redundancy. Suitable for non-critical office use. Not acceptable for any service hosting sensitive data or continuous business applications.
Redundant components (UPS units, generators). Allows maintenance without service interruption. Recommended for universities, corporate headquarters and private clinics.
Dual power path, no critical equipment on a single path. Tolerates single failures. Recommended standard for research centres with critical data and strategic public institutions.
Even an Algerian Tier I must include a correctly sized UPS and a generator with automatic changeover. Not to exceed the international standard, but to compensate for the reality of the local distribution grid.
Facilities concerned
Compute servers, research databases, digital teaching systems: services that cannot tolerate prolonged interruption or data loss. This is also the context of our ongoing project at the École Nationale Polytechnique de Constantine.
ERP, e-mail, file servers, IP telephony: an outage costs productivity and reputation. A corporate data centre must be sized on the number of workstations and business applications, not on a rough estimate.
Specifications with documentation requirements: execution drawings, acceptance reports, as-built drawings. Documentary traceability is non-negotiable in public procurement. We deliver the complete file at handover.
Patient records, medical imaging, hospital information systems: data whose loss or unavailability directly affects care. Service continuity is not a preference, it is a functional obligation.
Reservation management, centralised WiFi, satellite TV, access control: services that stop if the central server goes down. A guest without WiFi in the room is a guest who leaves a negative review.
Our approach
A data centre is not sized by eye. The preliminary study produces an electrical power assessment and a thermal load assessment, the two figures on which the whole design rests. Without them, the UPS is under- or over-sized, and cooling chills what does not need it while heating what should be cold.
What our study phase systematically includes:
The handover file includes as-built drawings, commissioning reports and operating manuals. If we are unavailable in three years, your system remains maintainable by any qualified technician.
Frequently asked questions
A conventional server room hosts equipment without redundancy or dedicated cooling. It is often a cabinet in a corridor or a room with a wall-mounted air conditioner. A data centre is designed with guaranteed availability levels, precision cooling sized on the real thermal load and reinforced physical security. The difference is fundamentally a matter of design rigour, not size.
In Algeria, grid instability calls for at least a UPS and a generator with automatic changeover, even for a Tier I. For critical services such as research databases, hospital information systems or corporate ERP, Tier II is the serious minimum. Tier III is justified when an interruption has direct consequences for people or for continuous commercial operations.
Yes, subject to a prior technical survey. We assess the available electrical capacity, the feasibility of precision cooling in the existing space, cabling constraints and the compliance of physical security. It is not always cheaper than starting from scratch, but it is an option worth costing before deciding.
Between 6 and 16 weeks depending on size and complexity, including 2 to 3 weeks of preliminary study before any order. Projects launched without a preliminary study consistently cost more to correct during execution than to design properly from the start.
Yes. CCTV in Algeria is regulated by executive decree 09-410: installation requires a licence from the Ministry of the Interior, whether for a server room, a corporate lobby or a car park. EURL Sidouni Technologie holds a Type 1 licence, which covers all electronic surveillance installations.
