Redundant Hardware Architecture - The NET1Plus
Hosted Exchange infrastructure is implemented as a front-end/back-end
configuration. The load-balanced front-end cluster processes all
inbound SMTP, HTTPS, RPC-HTTPS and Wireless Sync connections. The
back-end servers handle all message stores and are connected to both DAS
and SAN storage subsystems.
The front-end/back-end design secures the back-end servers and
provides robust performance as well as redundancy and scalability. It also
allows us to perform maintenance and add additional capacity as needed without
causing downtime.
Immediate Hardware Replacement - We maintain an
inventory of cold spare servers that are identical to our live production
servers. By having spare complete servers available the risk of
downtime due to unavailable spare parts, shipping delays and compatibility
issues is virtually eliminated.
Here's the non-technical version of that - For
those of you who are not so technically savvy to understand what all that means
-- basically it means that there multiple computer servers performing the same
tasks and they all share the workload. In the event that one of the servers
fail or is taken out of service for maintenance, the others will continue to
operate ensuring no interruption in mail service. Additionally we have
spare servers standing by in the event that we have to replace hardware
quickly.
Data Center and Internet Connectivity - Our Hosted
Exchange infrastructure is housed in a state-of-the-art, 24x7 Monitored Data
Center, with redundant Internet feeds, fire suppression, generator
back-up, advanced cooling and climate controls, keycard access, and
digital video recording. We also maintain equipment at a secondary Data
Center where we house secondary DNS Servers and Secondary Mail
servers. This approach ensures that, on the remote chance, if any
equipment, connection or network component fails at the primary data
center making it unreachable, mail will be delivered to the secondary mail
server for later final delivery.
