Facility in Citywest opened for business in September
last year. It is a purpose built world-class centre
designed to the highest standards and boasts the
following features:

To find out more about the facility, view
the video clip or alternatively, take
the virtual tour.
The facility measuring 30,000 sq ft, is built to the
highest environmental specifications. The raised floor
is at 900mm from the floor slab, with a clear 3m from
raised floor to ceiling. The environmentals include
FM200 fire suppression systems and automatic alert notification
to the emergency services.
In relation to power, the base load is via a new 10kV
ring main constructed in Citywest by the ESB. Plant
is designed to accept power from a second source as
soon as one is available. UPS systems are designed to
provide 100% redundancy. Battery autonomy time is 10
minutes per UPS at full load. In relation to generators
the design is N+1, with each individual set fuelled
from a day tank, connected to a central fuel supply.
Air conditioning systems and security are designed to
Class A standards, and security includes CCTV monitoring
internally and externally, 24 hour manned security,
biometric scanning and all other elements you would
expect in a world-class facility.

Security
The highest level of security has been implemented
in the rack areas, which is considered to be the zone
of highest importance. Biometric palm sensory access control
covers all entry points to rack areas and any unprotected
potential paths to rack areas. Outside the rack area access
is controlled using Isocards.
All approaches to the buildings are covered by a closed
circuit television system (CCTV) which is monitored by
our 24x7 security presence. A camera matrix involving
a multi-scope digital recorder system has been installed.
The system features Video Motion Detection to capture
images and record them digitally. Full camera coverage
is provided for rack areas. To find out more about security,

Power
Primary backup power in the event of a utility supply
failure is provided by a UPS system. The plant electrical
infrastructure has been arranged so that customers requiring
a redundant supply can be facilitated. UPS is designed
to provide 100% redundancy.
The base load power to the site is via a 10.5kV radial
circuit, supplied in Citywest by the ESB. The preferred
supply criteria for the site is a dual supply. To this
end the plant has been designed to accept a second supply
when one becomes available. The emergency generating
plant supplies power in the event of a utility supply
failure. Diesel generators supply base load power to the
site within 30 seconds of a utility power failure (the
UPS system supplies essential load until generators are
operational).
Busbars are arranged so that each rack has access to a
normal and an alternate supply.
Generator loading occurs in a sequenced manner. Each UPS
is configured to ramp load onto the generator bank in
a sequenced fashion. Generators are arranged in an N+1
configuration to allow for any one unit being out of service.
Depending on building load, Generators can be configured
to provide 100% redundancy (2N). Generation is at 400V,
transformed to 10.5kV. Transformers are dry-type.
Power distribution from the UPS to the racks is via custom
built, individually specified, 400v distribution panels.
Distribution panels supply a network of 160A rated (80A
design current (allows for excessive neutral currents)),
TP&N, under floor busbar trunking. To find out
more about the power system, view
the video clip. |
Environmentals
All rooms at the eircom facility are protected
to IS3218 P1 & BS7273 and associated standards. There
are two systems; a house alarm covering general office
and circulation areas and a fire suppression system in
the Rack Areas. Both systems are analogue addressable.
FM200 is used as the extinguishant. All rack, under floor
areas, and ceiling voids are covered.
Down flow air re-circulation type computer room air conditioning
units are provided for all rack and hosting support areas
that require close environmental control. Each unit is
capable of stand-alone operation, controlling the environment
based on return air conditions to the unit. One standby
unit is provided per individual rack area. Sequencing
control of the standby unit is provided. |

Cabling
The cabling infrastructure for Citywest is based on Avaya
(formerly Lucent Technologies) Category 6 GigaSPEED technology.
The fibre optic cable is primarily single mode throughout
the facility and based on Avaya's "LazrSPEED"
technology. All fibre cable runs are installed in an ADC
Kentrox fibre tray which runs around the perimeter of
each Rack area and is interconnected to allow for diverse
routing of the fibre cables. Fibre trays terminate in
the Telco room where they are cross patched to the Optical
Distribution Frame for connection to the external eircom
Network.
Networks
The Facility at Citywest is carrier neutral ensuring
that network services can be provided to customers either
by eircom, another licensed operator or a combination
of both. This provides true network resilience at the
carrier level.
The facility in Citywest uses Foundry Network's layer
three switches to provide local area connectivity for
servers. Within each Customer POD the network connections
from servers can be grouped into a single Virtual LAN
(VLAN) for segmentation purposes if required. Standalone
Ethernet switches can also be provided to connect administrative
users and the staging area during the Activation/implementation
phase.
Connectivity from a customer POD can be via a fully
redundant switched infrastructure and connection to
our ISP is over diversely routed high capacity links.
This provides a fault tolerant infrastructure to carry
data to the Internet. Customised communication solutions
using Frame Relay, leased links, Business IP or ISDN
can be provided on site.
