Vosity Network Operations Center
|
Located in Needham, Massachusetts Vosity's data center is located in a building that was originally
constructed for heavy machinery operation. The floors and ceilings are composed of steel and poured
concrete. When converted to a data center, poured concrete pads were also added to the concreate floors
to house the computing equipment elevated from any potential water damages.
The data center maintains a consistently cooled and air-conditioned environment with properly
positioned air conditioners, fans, and air filtering systems.
Power
Rendundant Power is supplied by electrical service, redundant ups backup systems on each rack,
and a natural-gas backup generator for the facility.
Security
Access to the facility is provided through a button-coded door locking mechanism. A motion-detected
security system is installed which provides motion detectors and automatic call-back notification
to Vosity personel given a questionable security breach. The security system is connected with local police and
fire for immediate notificaton. Wireless cameras are also installed for remote monitoring and
management.
Internet Connectivity & Bandwidth
Vosity provides 99.999% guaranteed uptime for shared and dedicated internet connections (from partial T1's to OC3's).
Vosity's last-mile internet feed is provided by Verizon and is managed by Savvis Communications with guaranteed 99.999% uptime.
In addition, Vosity has installed an additional internet feed from a wireless internet provider that will also provide failover
redundancy for the internet connection. With this internet configuration, Vosity's goal is to provide virtually 100% uptime.
Any minimal downtimes should only be related to planned and scheduled system maintenance.
Server Architecture
Vosity provides a highly-scalable, fully redundant server architecture
from its internet connections down to its web, mail, ftp and transaction servers.
At the front end of the Vosity server architecture is a high-end CISCO Catalyst 6500 router that takes in dual
internet feeds and connects to a CISCO Firewall (PIX 520). The PIX Firewall is redundant for failover purposes. The Firewalls provide
security and intrusion detection/prevention services. The Firewall(s) connects with with a CISCO Load balancer (LDIR 430).
The Load Balancer is also redundant for failover purposes. The Load Balancers provide a timely distribution of the transaction request to the network of
available servers to optimally service the request, whether it's a web page view or an ecommerce transaction.
The redundant Load balancers are connected to a network of web, email, ftp, and transaction servers.
The Compaq Proliant and Dell
Poweredge transaction servers have RAID arrays to provide disk/failover redundancy for continued operation. A combination of Windows and
UNIX servers are used as ftp servers which are also redundant and serve as the image servers for the web site/store graphics as
well as services for upload/download data transactions.
Networked storage disk farms for data storage and backup purposes are also provided and available.
All servers are configured to be accessible via remote control monitoring software for Vosity personnel to perform local and
remote administration services.
