The primary ServePath / ColoServe data center was by

built by WorldCom in 2000. The building also houses

“super-nodes” for MCI and AT&T local phone service in San

Francisco, so it is considered an “essential” facility because 911

calls are routed here. We share generators, power, cooling, and

fire suppression infrastructure with MCI (formerly Worldcom),

including dual 2 Megawatt generators that support the critical

power requirements and operations of the building.

l Built by Worldcom in 2000 as expansion space

l ServePath / ColoServe reopened it in September 2003

l 20,000 square feet of capacity

l Plenty of available power and cooling

Building ConstructionOur data center is located in the San Francisco Telecom Center,

conveniently located just south of San Francisco’s Financial

District. This 100% occupied telecom building also houses AT&T

and MCI super nodes. The building was originally built in 1924

as a Marine Corps Depot for heavy equipment, so the five story

structure is built of extra-thick, reinforced cast-in-place concrete.

The building was seismically retrofitted in 1999 to convert the

existing warehouse into a Telecom Center in accordance with

San Francisco’s Uniform Building Code, and then retrofitted a

second time to exceed those standards by tenants AT&T and MCI

in accordance with their stringent telecom carrier standards.

l Secure building originally used for storage of military tanks

and equipment

l Built on solid bedrock, seismically retrofit in 1999 to meet

rigorous City of San Francisco building codes

l Six separate fiber entrances with 2 fiber rooms. A large portion

of the Bay Bridge Fiber Consortium terminates in the building

(cross-bay Fiber).

l State-of-the-art redundant systems for power, HVAC, fiber

connectivity, seismic precautions and fire suppression.

Data Center Overview

Fire SuppressionOur state-of-the-art fire suppression is a grid of “VESDA”

AnaLaser-brand laser smoke sensors that are 10,000 times more

sensitive than conventional smoke detectors and capable of

detecting incipient smoldering. This grid has a total of 400

sensors, with 200 located on the ceiling and 200 located under

the raised floor.

The system is monitored 24 x 7 on-site and off-site by both

ServePath and MCI NOCs. The fire suppression is state-of-

the-art TotalPac double interlocked dry-pipe preaction, with

tightly defined zones to isolate and extinguish any fires without

affecting surrounding areas.

l VESDA laser smoke detection with dry pipe suppression

l 200 below raised floor laser sensors and 200 in the ceiling

l Tightly defined preaction zones for localized fire extinguishing

l Monitored and maintained by both ServePath /

ColoServe and MCI

SecurityThe San Francisco Telecom

Center where our data center

is located maintains the

highest possible standards for

physical security. This facility

is home to only three tenants,

MCI, AT&T and ServePath /

ColoServe, and is equipped

with state-of-the-art video and

audio monitoring equipment

and 24 x 7 on-site guards. All people entering the building are

required to register with the security office and leave a valid ID

while in the building. Those not on the access list are not allowed

into the building without an escort. We check in visitors a second

time prior to entry into our data center on the second floor. The

ServePath / ColoServe NOC is staffed 24 x 365 and is afforded a

direct line-of-site view into the data center.

CoolingServePath / ColoServe has tremendous cooling

infrastructure, with dual redundant chilled water

supply loops and multiple Liebert air conditioning

units pumping cold air into the pressurized raised

floor of our data center. Chilled water is provided by

the roof cooling towers, which also provide chilled

water for MCI’s critical systems. Additional chilled water

supply and return valves are already plumbed every

thirty feet along the perimeter of our data center,

allowing for rapid installation of additional Liebert

units should increased cooling capacity be required.

l n+1 Liebert VACs w/n+1 supply loops and chillers:

l Up to 300 tons of cooling capacity that runs on

MCI’s chilled water systems

l Raised floor system for efficient distribution

of cooling

Fiber and Bandwidth ProvidersServePath / ColoServe operates its own screaming-fast network™,

featuring multi-homed bandwidth with connections to over 40

networks. We route traffic over major Tier 1 Internet backbones

such as UUNet/MCI, Level 3, NTT/Verio, and AboveNet, with

no low-quality bandwidth and plenty of network capacity for

maximum reliability and scalability.

Power InfrastructureOur data center power is fed by conditioned UPS

(uninterruptible power supply) electricity, with redundant

feeds from dual 2 Megawatt generators that also support

critical MCI phone switches. One generator can power the

entire building for several days time, and there is 20,000

gallons of reserve diesel fuel on site. These generators are

tested monthly per stringent MCI protocols.

l Redundant power feeds with UPS power

l 2 x 2 megawatt generators that also power MCI’s local

phone switches

l 20,000 gallons of diesel fuel on site, hot-refill ready

l Six separate building fiber entrances with 2 fiber rooms.

The Bay Bridge Fiber Consortium terminates in the building

(cross-bay Fiber).

l ServePath / ColoServe has 2 separate fiber entrances on

different streets (both Spear and Harrison) for an additional

layer of redundancy
