UMIS’ Hosting Centre is a state-of-the-art
facility designed to host and manage business-critical I.T. solutions
around-the-clock. Our Hosting Centre utilise the latest technologies
in order to provide the highest infrastructure reliability and availability
in the industry.
UMIS’ Hosting Centre has been designed to be entirely redundant
and is maintained through a strictly controlled maintenance scheme
on all systems. This allows for any infrastructure component to
be maintained while its counterpart performs the tasks at hand.
The third component is on standby to deal with outages of the active
components.
Electrical
System
To guarantee uninterrupted availability of main power, 3 x 1600KVA
and 2 x 2000KVA Synchromeshed Generators back up the site power.
The generators start up immediately when a drop or mains' failure
is sensed and are able to cater for full load within approximately
30 seconds after start-up.
There is a 50 cubic meter diesel tank on site containing 15000 litres
of fuel. This provides 15 hours of continuous full load power for
the 3 x 1600KV generators. There are also another two separate tanks
each containing 4600 litres of fuel that supply the 2 x 2000KVA
generators. This provides 12 hours of continuous full load power.
Fire Detection System
VESDA (Very Early Smoke Detection Apparatus) systems continually
sample the air for non-combustible matter and combustible ion particles.
They immediately report any irregularities to the facility staff
and the Network Operation Centres.
All detectors generate a ‘live’ signal every few seconds.
Should a detector not send this signal, a controlling device higher
up the hierarchy generates an alarm report.
Fire Suppression System
If the volume of detected combustible particles reaches a pre-defined
threshold, inert gases will flood the endangered room from above
to force out the atmosphere – including the oxygen and combustible
particles it may hold. The gas itself holds no water and will therefore
not damage any device hosted in the Center.
To rapidly remove the combustible atmosphere large vents are automatically
opened for a short time span. They are then again closed to trap
the non-combustible atmosphere in the danger area. The inert suppression
gases are stored in a separate compartment of the building and are
monitored continuously.
Note: Fires exist with the presence of three
components: combustible matter, oxygen and a temperature at which
the combustible matter ignites or burns. The fire suppression system
will remove at least one from these (oxygen) and, under most circumstances,
even a second (combustible gases). Removing just one of these three
guarantees the fire will terminate.
Air Cooliong
and Handling Systems
The Data Centre utilises a chilled water system for environmental
control using Stulz Modular-Line air conditioning systems. The particular
unit model is determined on a suite-by-suite basis and provides
the following environment:
Temperature: 22°C +/- 2°C
Relative humidity: 50% non-condensing
Air filtration: Class EU5
The capacity of the units are designed to handle 400 Watts per square
meter and are installed on an N+1 basis (one more than is required
to provides resilience in the event of one unit failing).
Security Systems
CCTV from the Centre’s Security Station monitors the exterior
of the building whilst uniformed security staff control access to
the actual Data Centre. Only authorised personnel are allowed access
to the site, with a minimum of 24 hours notice being required for
security clearance before access is granted.
All visitors must sign in at reception for clearance verification.
Once authorised visitors are issued with a key-card which is programmed
at the time of issue and allows access only to the areas appropriate
to the visitor. The key-cards are valid for one visit only.
Additionally, internal CCTV ensures that all doors to clients’
suites are supervised and monitors the corridors throughout the
centre.
The Data Centre will tailor its security to any of its individual
clients’ needs, with all security systems being able to meet
client insurance specifications. The Data Centre is also capable
of monitoring and transmitting all alarm specifications to provide
the highest customer satisfaction.
