Platform
Redundancy
BDS maintains
two independent and totally redundant data sites located 27 miles apart for
redundancy live disaster recovery. This redundant architecture provides fail-safe
performance should a client's application or database becomes unavailable
due to communications or hardware issues.
Each site
maintains a full complement of application, database, and email servers that
provide duplicate capacity. Server file structures are "clustered"
to maintain real-time duplication of inbound and outbound data files, update
scripts and any other system s support files. Database servers at each site
use Microsoft SQL Server technology and are synchronized in real time providing
a virtual database for our clients.
A dedicated
T-1 Line provided by Southwestern Bell (SBC) ensures high-capacity, real-time
communications between the Woodlands and CyrusOne site. For frame relay customers,
access to both data centers is provided via dual frame ports at a minimum
512k CIR (committed information rate).
At the
clients option, its hosted databases, module applications, and raw data files
are replicated real-time at an alternate location to provide additional insurance
against downtime due to primary data center disaster or unavailability. This
secondary system run as a "hot-site" can be brought online within
hours. The CyrusOne site is a fully staffed "co-location" site that
provides full back-up capabilities with consistent power supplied by backup
comprised of battery systems and diesel generators.
  
An
SBC-supplied dual-circuit line provides Client connections to both Woodlands
and Cyrus data centers. BDS works with the individual Clients to implement
custom network-to-network security configurations to meet the Clients' requirements.
Recovery
Procedures and Drill
For all
its ASP clients, BDS recommends the development of a plan, customized to each
client and its interfaces, to recover from unavailability of one of BDS' data
centers. The BDS DR Plan, developed over a two-week period, provides: |
