- The Core refers to central point of
the network, and therefore reducing the number of problems involving the core
will communicate that information traffic is running smoothly and efficiently.
- Server Consolidation is being offset
by new hosting agreements (department servers) and major new systems (ERP and
ERMS, etc.).
- TB = Terabyte. GB = Gigabyte. Mbps = megabits per
second.
FUTURE BUDGET CONSIDERATIONS:
-
The network infrastructure is critical to the effective
delivery of electronic government solutions.
Future funding will be needed to enhance, repair, replace, and/or
upgrade infrastructure. Broadband
connectivity will reach a majority of the County's homes and businesses within
the next two to three years. When it
does, the County's infrastructure must be able to accommodate secure
high-bandwidth, anytime, anywhere access.
-
Upgrade/refresh server capacity and performance to
industry standards in order to support county enterprise system and
internet/intranet needs.
-
Converge voice and data into a single integrated network
for efficiencies.
-
Research implementing multi-media applications that
integrate voice, data and video for the provision of customer service.
-
Enhance and expand existing video services for County
staff.
-
Deploy server consolidation and virtualization process
to result in more cost-effective and efficient management of backend systems.
-
Enhance ability to provide emergency network
infrastructure services (data, video, and voice) and support for Arlington
County first responders and emergency operations personnel.
