The Physical Structure:
Located at 511 Congress Street in Portland, ME, Know Technology's
(KT) data center (DC) is part of a larger office space (Office).
The building is owned by 511 LC, and is currently managed by
Boulos Management Company. KT's Office is located on
the ground floor right side corner of the building and has
2 entrances from the street, both of which are separate from
the building's main entrance. The Office is a large open
space with about 3,300 square feet, having originally been
designed for a bank. The DC is a separate 350 sq.ft (32' x
11') room within our Office that utilizes the systems
described below. Also described is the vault (former bank
vault), which contains data and power sources for our data center.
Electrical Systems:
Power is supplied by Central Maine Power to the building's
transformers from the city's underground power grid,
the same high availability grid that powers Maine Medical
Center. The 3 transformers are located at the back of the
building, and are locked within their own concrete and fenced structure.
From the building power supply KT has a 277/480 volt feed
from the basement to our Office. There is a 150 amp automatic
transfer switch for our onsite generator and a manual
transfer switch on the ground floor for use with a mobile
generator. Our onsite generator is a Generac 100kw unit and
is capable of providing enough power to operate the DC and its environmental
systems. Following the transfer switches the power is distributed
to various locked sub panels all available within the Office
space.
Power to the DC room is from one of four sources.
Commercial power which is straight from a panel located
in the locked vault, and either of three APC 16kva Symmetra N+1 UPS units,
also feed from the vault panel. All power
into the DC is delivered in conduit from 30amp circuits to (40) labeled
30amp twist lock connectors suspended under the cable tray
above the racks. The UPS units each feed their own locked sub panels providing
three uninterruptible power sources for most racks. The UPS
units are monitored via SNMP networking monitoring system
described later. All power equipment and rack enclosures are grounded
to the buildings electrical ground.
HVAC Systems:
Heating, Ventilating and Air Conditioning for the Office
is provided by the buildings equipment. Air Conditioning
for the DC room is provided by (3) 5-ton Trane AHUs sharing
two Trane rooftop condenser units. The units are
each connected to their own thermostats. One unit is configured
as a backup, to operate only when the primary system is
unable to meet the cooling demands. The vault is cooled by a third unit.
Air distribution within
the DC is designed so cool air is supplied at the front
of the racks and the warm air is returned from the back.
All HVAC systems are regularly maintained as part of a service
agreement, including 24x7 emergency services.
Fire Protection:
The building's fire protection system, which the office is
part of, includes central monitoring, alarms, and a wet
sprinkler system. The DC room has its own Inergen fire protection system,
and its roof and walls are sealed to prevent the building's
wet system from entering. The Inergen system protects the vault
and DC. There are a combination of photoelectric and ionization
detectors in each space, any two of which must trip for the
system to discharge. There are also 3 labeled manual pull stations,
2 within the DC room and one outside the entrance, capable
of discharging the system. The system issues a series of alerts
with strobe, bell, and horn, to indicate system warnings. KT
has had all of their onsite employees trained in the use of
this system. The Inergen is a mixture of gases used to lower
the oxygen levels within a confined air space which suppresses a fire.
This system is safe for both humans and electrical equipment.
The gear is tested as part of a regular maintenance program.
Security Systems and Access Control:
The building has its own surveillance system covering the
back of the building and the major entrances/exits. Furthermore,
the building landlord contracts after-hours security to provide hourly foot
patrol of the outside of premises.
The access control system uses a key "fob" issued
to customers who are current data center customers and have
gear in the KTDC. The access control system manages one outside
door, an interior Office door, and the door to the KTDC room.
Each key fob enables the system to allow, block, record and
monitor all incoming access attempts. The system also monitors
open door conditions and alerts when predefined time limits
are exceeded.
KT uses environmental monitoring and a video feed
to monitor conditions within the DC room. The environmental
monitoring is reading light, temperature and humidity levels every 30
seconds. If the reported readings are outside our predefined
limits our network monitoring system puts a series of notifications
into action.
Network Monitoring System:
Monitoring and alerting of critical systems is provided by KTL's network monitoring system.
The system is configured to use various protocols to collect and report on all systems critical to the KTDC operation. When a problem is picked by the monitors, a series of alerts are triggered to notify management staff.
Data Systems:
Data services are provided to the building over a sonet fiber
optic network and enter our Office through the
vault. Oxford Networks, our data provider, has internet data connections ranging from OC-3 to OC-12
with AT&T, Cogent, MCI and Sprint. All Data Services are delivered
via redundant Cisco and HP Routing and Switching systems.
