connected by a Wide Area Network (WAN) - fibre,
ATM, etc.
-
Each clustered scalable to 16 32-CPU
servers
-
Same
single-image cluster server features as single
cluster server design (HP TruCluster)
-
One Internet/Intranet IP address for
users to connect
-
Automatic load balancing to maintain
excellent application response times
-
High availability and automated
failover features designed into single servers,
clusters of servers and now for two clustered
servers that are geographically dispersed
-
Both sets of clustered servers act
as one system and are managed as one system
-
Add and remove clustered server
members on-the-fly
-
Fibre-channel based RAID storage
area network (SAN) arrays constantly updating each
other across WAN network
-
Should one entire cluster fail,
second cluster immediately takes over - users
refresh screen and continue
-
High-speed, high capacity UNIX
servers host key medEncounter applications
-
Standard internet browser application access
-
medEncounter applications and server
platforms designed for high-availability (24x7)
service

Redundant systems and components for
failover capability
-
Scalable by adding additional
servers on network
-

applications via HL7 standards
-
User connect via Virtual Private
Network Internet, Extranet or direct Ethernet
