SITEC owns the unique Datacenters installed in CorsicaInterconnected, they guarantee a maximum level of availability and continuity of service, while allowing our customers to have direct and privileged access to their installations and data.

The high level of expertise of our engineers and technicians is expressed through a permanent availability of our teams, 24/24, 7 days a year, guaranteeing optimal service in terms of proximity and speed of intervention.

The full range of “Datacenter” services

Public and private cloud rental spaces, dedicated solutions.

Associated services : Outsourcing project management, Information systems outsourcing, Business continuity and recovery plans. 

Telecommunications services:The historic accommodation site of SITEC  is its Ajaccio Datacenter. Since the beginning of 2014, a second Datacenter has been put into production in Bastia.

Thus, thanks to the doubling of operator links which serve these centers associated with an “inter-site” link between the latter, completely new functionalities are today exploited by SITEC.

From high availability production can be carried out in each of the Datacenters.

Depending on needs, one Datacenter can be backed up by the second and vice versa (Disaster Recovery Plan).

High availability production can also be done in both Datacenters simultaneously (Business Continuity Plan).

For these first two examples, the choice of Datacenter in which production takes place is very often linked to the nature of the project and the dependence on the corresponding telecommunications links (proximity, possibility of connecting the customer concerned, etc.).

The treatment centers have a computer room with double air conditioning equipment, with a false floor and false ceiling.

Electrical safety is ensured by:

Two synchronized redundant inverters.

A buffer battery system.

Ajaccio emergency generator (96 hours of autonomy at 70% of the maximum load of the computer room)

Bastia emergency generator (48 hours of autonomy at 70% of the maximum load of the computer room)

Passive safety of buildings is ensured by remote monitoring of installations : intrusion detection and fire fighting, access control and video surveillance.

Our Facilities

Secured access

Access to our facilities is via a system of access control, depending on the levels of accreditation assigned to staff and customers. A system of remote monitoring and intrusion detection completes the security of our various sites. 

Several operating areas (dedicated room, shared room, private room) are used according to the expectations of our customers. This allows us to offer solutions for hosting racks, servers in our shared bays, as well as IaaS and PaaS solutions.

like servers and storage without the need to : (Infrastructure as a Service) is a cloud computing model where the company maintains the applications, runtimes, databases, server software and the cloud provider maintains the virtualization, server hardware, storage, networks.

PaaS :  (Platform as a Service) is a "Cloud computing" model where the company only maintains its applications and the Cloud provider maintains the platform for running these applications (i.e. runtimes, databases, server software, virtualization?) as well as the infrastructure (server hardware, storage and networks).

Air-conditioning

Temperature maintenance (21°) is ensured by independent air conditioning units with reverse blowing (blowing into false floor and return to ambient), these devices are redundant. A temperature control system allows the triggering of additional cabinets in case the temperature exceeds 24°, or simply to take over in the event of maintenance on one of our cabinets.

Low Current Connection

All copper and fiber optic connections are distributed from the main inlet to the switching equipment placed in the racks, via suspended PVC cable trays. This architecture – high current / low current separation – allows to ensure the quality of information without fear of the effects linked to magnetic disturbances.

High Current Connection

Computer racks are equipped with power distribution units (PDUs) administrable et redundant. Each on-board hardware has two emergency power sources by two separate electrical networks.

The maximum permissible load is distributed with regard to the equipment integrated into the racks.

SITEC provides all electrical connections from the distribution cabinets to the IT racks. The provision includes the supply of Plexo boxes placed under the raised floor at the location of the customer's racks. The routing of the electrical connections is carried out on  insulated cable trays in the technical floor. 

The stabilization of the electric current is ensured by two redundant synchronized inverter/battery pairs.

Features of corrugated power supply

Delivered voltage: 230 V
Tolerance: +/- 1% in permanent mode, +/- 5% in transient period
Frequency: 50 Hz +/- 0,04%
Harmonic voltage distortion: < 5%

The autonomy of batteries provides power for all computer rooms for 30 minutes at full load, in the event of a complete power outage. To compensate for a possible power outage, we have generators with a power of 275KVA supplied by fuel oil tanks of 1 to 800 liters.

All of these devices make it possible to ensure platform stability whatever the distribution conditions of the electricity network.

Fire Protection

Fire protection is carried out through a automatic extinguishing system by inert gas A2+.

Our service offer

Server Solutions

Data centers SITEC are monitored and maintained by a team of technicians and engineers for a service on 2 levels of competence which covers 24/24.

Our teams are proficient in most server technologies on the market, namely:

Standalone rack servers
Rack servers with partially or fully relocated disks
Blade servers.
Virtual servers

virtualization

We master hypervisor solutions from VMware and Citrix XenServer, and we market our infrastructure solution on demand. Our customers can then manage their own virtual data center from start to finish (virtual networks, VMs, firewalls, VPN access servers, virtual storage, data backups, etc.)

.

Infrastructure accommodations

Our offer DCaaS (DataCenter as a Sservice) is intended for customers wishing
have an optimal hosting environment while maintaining control
total of their IT infrastructure.

It allows you to rent floor or cabinet space in our two Datacenters
in which our customers install their own server and network equipment.

Our customers can also benefit from: additional services, such as data backup or internet connection.

They have 24/7/365 access to their equipment, in a highly secure environment constantly monitored by our teams.

Storage

A complete range of storage solutions guaranteed a range of services
customizable as desired:

Storage Physical (Raid0 to Raid6)
Storage Virtual (Raid0 to Raid10)
Storage in cloud with synchronization and versioning

All our bays are equipped with dual controllers / dual ports.

Our data replication solutions enable us to offer disaster recovery plans (DRP) on remote sites, as well as file replication solutions and inter-datacenter array replication devices.

Network solutions

The availability of hosted applications is ensured by the redundancy of our network links.

Our accommodation infrastructure is served by 2 distinct fibers provided by the historic operator, and have installations positioned in regional POPs, allowing the use of fiber provided by Corsica Link Network (operated through a regional public service delegation).

Network links between the continent and Corsica

Our network benefits from 2 IP transits delivered by 2 different operators, and using 2 separate fibers.

The systems implemented by our teams in the Ajaccio and Bastia Datacenters make it possible to offer ISP redundancy to our customers. They allow us to satisfy the availability of hosted services independently of the contractual commitments of restoration time guarantee (GTR) subscribed to with local operators (GTR 4 hours).

Flow security devices

The Internet streams entering our facilities are Secure by stacking 2 layers of Firewall/Routers of different technologies. The servers hosted within our Datacenters are located in zones adapted (MZ, DMZ etc.) to the required activity.

Backbone

The heart of the network at SITEC is made up of switches configured in high physical and software availability, allowing for the tolerance of a possible failure of one of these materials without interruption of service.

SITEC Level 3 private networks coexist thanks to the implementation of VLANs (802.1Q), ensuring their watertightness. 

QoS Management

SITEC ensures fine management of QoS thanks to dedicated equipment (prioritization of flows by protocol, by IP addresses, by networks, regulation of flows, optimization of performances thanks to “shaping”). 

Anti-intrusion, Anti-spam

SITEC is equipped with probes (IPS) that protect its customers against network, application, or Internet attacks (detection and prevention mode).

Methodology and performance

We have developed our own SLO (tool for measuring quality of service) in order toanalyze availability applications hosted on our Datacenters. This tool is based on a set of "probes" positioned inside and outside the company. In the case of a WEB application, our probes simulate the navigation of an Internet user by cyclically repeating scenarios established according to the client's specifications, in order to measure actual airworthiness.

Data backup and outsourcing

We use robotic backup solutions and have LTOx type storage. specially developed scripts interface between backup robotics and backup servers for monitoring the operation and management of media outsourcing.

Backup servers are replicated between our two Datacenters.

The combination of all these devices allows us to guarantee the data restoration at the finest level.
