The Electrical System
For the sake of business continuity extending even to extreme circumstances when the civilian electrical infrastructures may be damaged, a sophisticated electrical system was designed and constructed that operates on externally supplied electricity from the national grid in times of calm but is accompanied by an additional system for emergencies that includes a UPS and advanced generators enabling the data center to continue operating autonomously with no reliance on electricity from outside.
The topology of the electrical system is based on 2 mutually independent input channels starting at the feed-in point from the electric company’s national grid. The electrical cable enters underground, and each channel is capable of supplying back-up electricity for the entire installation.
The subterranean power system is located in the B wing, with a double wall for reinforcement between the building and its environment. There are two underground diesel tanks for the generators, 30 tons each in volume, located in an underground fixture of reinforced concrete. The volume of the tanks suffices for continuous operation of the generators for 72 hours without external fuelling.
Monitoring the Buildings
Monitoring the Buildings
The entire structure is managed by a building control system which applies monitoring and control to all the building’s infrastructures (electricity, air conditioning, fire detection and extinguishing, and more). With various sensors located in the building’s infrastructure systems, monitoring continues 24 hours a day and any malfunction can be immediately pinpointed.

Israel’s Communications Hub
MedOne serves as Israel’s primary Hub for both external and internal communications.
MedOne established the Med Nautilus subterranean cable system, an optical fiber system configured in an undersea ring and integrated with a landside optical fiber system. Med Nautilus connects Israel with a number of European countries. Its survivability is exceptional, and its bandwidth potential is enormous. The company’s installations are the landing stations for the subterranean cable, and they connect Israel to the internet’s central backbone.
Accordingly, the MedOne installations host the communications providers, internet providers, and telephone companies who operate in Israel. They also host the Israeli Internet Exchange (IIX), a routing system which, upon request, provides connectivity with clients hosted at the installation.
MedOne maintains an MMR (a so-called meet-me room) enabling the company’s clients to connect directly at any required bandwidth, and with any required type of infrastructure, to any of the internet/cellular/communications providers, domestic or international, that operate in Israel.
Each of the company’s installations includes a number of separate, dedicated communications channels for accommodating the communications infrastructures of various providers and for increasing survivability.
MedOne, Israel’s pioneer in establishing data centers has set up some of the world’s most sophisticated and innovative data centers, in subterranean locations, with a unique system of infrastructures that are exceptional in their scale and in their survivability.
The three sites are located at industrial centers in northern and central Israel and together cover an area of 17,000 square meters (180,000 square feet). The data center sites can operate autonomously, , for 72 hours at once, thanks to emergency resources installed at the data centers themselves for use in time of need.
The location of the Data Centers enables clients to have their IT infrastructure hosted at whichever location they consider optimal, both for purposes of production and for purposes of DR.
Spacious Storage Facilities
The MedOne sites offer a total storage area of some 17,000 square meters (180,000 square feet), currently hosting more than 100,000 servers, so that your organization will never be short of space. This vast data centers hosting areas provides our customers with complete flexibility in choosing hosting space and with support for your organization and its IT infrastructures as they grow.
The Air Conditioning System
The air conditioning system has been designed to ensure N+1 redundancy in chillers and in the cooling tower. This system provides advanced cooling solutions that include cooling of water as well and provide for the cooling of cabinets where electricity consumption is high (high server density). The air conditioning system includes the following features:
- Double piping, in an A+B configuration, in the hosting rooms
- Water reservoirs providing for 72 hours of continuous work, under full load, with no external supply of water
- Suitability for operation in difficult atmospheric conditions
- Ability to adjust the temperature as appropriate in the various areas of the installation
- Constant monitoring of humidity
The air conditioning system is based on especially efficient equipment that reduces the operating expense. The circulating cold water is a redundant system making complete cooling backup possible for the client systems, the pipes, the electrical system, and the power generation system.
The air conditioning system also provides for cooling in the hosting room by means of air-cooling through the underfloor space and/or in-row water cooling among the servers, distributed throughout the various client areas.
The air conditioning system is operated by a control system consistent with the operation of the various other systems of equipment.
The Fire Extinguishing System
The fire extinguishing system is based on advanced circles of deployment for detection, alerting, and extinguishing. They include a sampling system located in the clients’ rooms and cabinets. The system complies with Israeli and NFPA standards, and it is monitored by the building’s control system. These are the fire extinguishing system’s main features:
- The fire extinguishing system is selective, dividing the installation and the hosting rooms into distinct fire areas. If fire erupts in one area, the aim is to halt it before it can have any effect on other areas.
- All areas —the hosting rooms, electricity and equipment rooms, underfloor space, roof, and passageways — are continuously monitored by a fire detection system. The equipment in the hosting rooms will continue to operate even if fire has broken out in the building or in one of its systems.
- To halt any fire that breaks out in the rooms of the site, the fire extinguishing system installed there floods the protected area with inert fire-extinguishing gas (FM-200).
- The fire detection system in the protected areas operates as follows: The ventilation and cooling in the area where the fire broke out are turned off when the system signals an alarm. At the same time, the alarm is sounded audibly inside the same area for 10 seconds; and then the fire-extinguishing gas is released.
- An additional system is present for backup, based on a pre-action water system that is triggered only if and when the temperature reaches a pre-specified level indicating that the gas-based system has failed.
The Facilities, Security
For maximum survivability, each MedOne site was planned as two separate buildings, one constructed inside the other. The gap thus created, together with the engineering characteristics of each of
The physical security system is strict and uncompromising. During the planning and construction of the IT installations, strong consideration was given to a wide variety of threats such as sabotage, concealed or unconcealed attempts at intrusion, and attempts to introduce electronic equipment for monitoring or disturbance. Because the information stored at the sites is sensitive and is of interest to hostile elements (both commercial and nationalistic), exceptional care is exercised with respect to the means of safety and security.
In order to withstand external threats, the installations are protected by a massive double enclosure of reinforced concrete. The entire site and the project rooms inside it have been checked for resistance to the danger of explosives from outside, including direct hits at the structure’s critical points and penetration through unprotected openings (balcony/window) as well as explosions inside. Also taken into account are scenarios such as a nearby hit and an underground explosion near the structure’s wall. The installation’s special-purpose equipment — both for IT and for power — is located at underground levels, inside an internal structure which occupies an outer enclosure of reinforced concrete, so that the equipment is maximally protected against most of those threats.
The installation’s infrastructure systems are located in a separate structure inside the IT installation itself. They too are inside an underground building within the walls of the structure. Thus they are protected every moment of the day and night by the underground structure’s double enclosure of reinforced concrete, by the installation’s security system (access control and CCTV), and by its staff of guards.
The installation’s human guard regime represents the highest standard in terms of the installed systems employed, in terms of the staff’s selection and training, and in terms of the security procedures in force on site.
Altogether there are eight circles of security deployment, external and internal, including fencing, cameras, gates, guards, a magnetic card system, a palmprint system, caged areas, and separation of rooms. Access to various sections of the installation requires various different levels of permission, and sally ports — where one door closes behind an entering visitor and the next door inward will not open without another step of authentication — prevent unauthorized wandering.
The security staff has been careful chosen, having qualified through many levels of selection and succeeded in comprehensive tests of personal reliability. The staff consists of combat unit veterans and graduates of military command courses.
The security scheme at the facility is arranged so that each of its constituent systems supports and backs up the others in real time.
All the door and entranceways are monitored by an entry control system that uses proximity cards, biometric hand readers, and sally ports for maximal separation between the various parts of the facility as each visitor is guided in the appropriate direction. Most of the doors are also monitored by an intrusion detection system that handles warnings in additional cases. The installation is photographed throughout the day and night by a closed-circuit surveillance and recording system that covers all the external views as well as the interior.
To manage the complex and varied deployment of systems inside the MedOne installations, a sophisticated command-and-control station has been put in place. There all the activity on all the systems can be monitored and supervised in keeping with current needs and scenarios.
the buildings, protects the overall configuration from external sources of damage such as shock waves from explosives and earthquakes.
The buildings are 15 meters underground (49 feet), and there is a distinct physical separation between the hosting rooms and the support system rooms. The hosting rooms’ internal design and engineering characteristics make them suitable for hosting all existing server types, with almost no weight limitation.
