Our Environment and Data Centres
OUR HOSTED EXCHANGE ENVIRONMENT
Our Exchange environment is built for constant uptime and the highest reliability.
Using the latest Microsoft best practices for running Exchange, the system includes
complete redundancy – with no single points of failure – across our
network, servers and data connectivity. In fact, our hosted Exchange is far more
robust than the email servers at many major corporations.
SERVERS & STORAGE
Our Exchange servers are based on a passive-active cluster server configuration
to provide seamless failover when a cluster node is unavailable or is taken offline
for maintenance. Redundant and load-balanced Exchange front-end servers also increase
reliability.
Your data resides on a storage area network (SAN) by EMC, the premiere storage brand.
With total redundancy – clusters of disks in a RAID array – if one should
fail, the system continues working. Intra-SAN and tape back-ups ensure there is
no single point of failure anywhere in the storage system.
NETWORK
Our highly-resilient network has two diverse network entry points which manage traffic
flow to the Internet, with another dedicated high-speed link to a separate California
location. That second location itself has a failover link to a third location nearby
for ultimate uptime in connectivity.
Traffic inside the Exchange environment is managed by Cisco routers and switches,
with HP rack distribution switches. An advanced Netscreen firewall protects the
[COMPANY NAME] Exchange infrastructure, with all ports closed except for essential
ones and 100% of incoming traffic monitored by anti-spam and anti-virus applications.
24x7 MONITORING
Exchange servers are monitored 24x7 using a comprehensive and state-of-the-art MOM
management system. This allows immediate detection of both potential and actual
issues, which are tackled by our multiple technicians – on standby, day and
night. MOM looks at a full range of metrics, including CPU, memory and disk space
utilization, the size of the mail queues, the status of Outlook Web Access (OWA),
different Exchange-related ports and RPC latency.
OUR HOSTED EXCHANGE DATACENTER
When you host your business-critical email system with [COMPANY NAME], your email
and data will be hosted in one of the world’s premiere datacenters. It includes
all the latest technology in server, data connectivity, power, cooling, security
and infrastructure.
ENVIRONMENT
The datacenter is equipped with the latest environmental control units that give
a 100% SLA-guaranteed temperature and humidity within a certain range. It also uses
the most advanced fire-suppression systems available. The datacenter has an 18-inch
raised floor and is zone 4 certified for earthquakes.
POWER
With main power supplied by Silicon Valley Power, ranked in the top-quartile nationally
in reliability, our class-A data center is designed for N+1 redundancy and is equipped
with redundant power feeds, HiTEC uninterruptible power supply systems and back-up
diesel generator power. This gives a guaranteed 99.999% availability for power.
CONNECTIVITY
Our datacenter is a carrier-neutral facility with two diverse network entry points
and a direct Internet backbone connection. Failover arrangements ensure that data
connectivity never goes down. With our hosted Exchange, you always have reliable
access to your server, both from your desktop or via Outlook Web Access wherever
you travel.
SECURITY
As a world-class datacenter, our premises are closely monitored and guarded, 24x7x365.
Sophisticated pan/tilt CCTV cameras cover every part of the datacenter and access
to our servers is restricted to a limited number of authorized engineers.
Security is strictly enforced using the very latest technology, including man-trap
technology between lobby and datacenter, motion sensors and controlled ID key-cards,
as well as security guards stationed at every entrance to the site.
