Designed For Platform Longevity
Pegasus 2008 is the 3rd Major Release of the Pegasus Platform, scheduled for deployment to
Production, at Entergy Services, Inc., in late 2008. Pegasus 2006 is currently running in
Production at Entergy, at 5 Geographical Sites, on 13 Servers (operating 7x24 in an Unattended
Production Environment).
Pegasus 2003 (the 1st Production Release of Pegasus) was developed using 100% “Managed
Code” on .NET Framework 1.1. Pegasus 2006 (the 2nd Production Release of Pegasus) was
developed using 100% “Managed Code” on .NET Framework 2.0. Pegasus 2008 will be deployed
to Production as 100% “Managed Code” using .NET Framework 3.0. The PDC integrates tightly
with the EMS SCADA Databases, is written 100% in C++, and is the only Pegasus Platform
Subsystem not written as “Managed Code” on the .NET Framework.
All Pegasus Data Server Applications are fully multi-threaded and most can be configured to
additionally run as multiple Application Instances (with each App Instance fully multi-threaded).
This allows Pegasus Servers to take full advantage of the latest Multi-Core CPU Technologies and
large RAM sizes. The Pegasus Smart Client is also fully multi-threaded and uses the latest UI
techniques.
After deployment of Pegasus 2008, all Pegasus Data Servers Applications will be ported to
native, 100% “Managed 64-bit Code” using Microsoft’s latest 64-bit .NET Framework. This
allows Pegasus Data Server Applications to take full advantage of 2009 – 2010 hardware with
very large RAM (128 GB or more, per Server). Large RAM sizes allows Pegasus to scale to very
large EMS SCADA and Network Databases for very large Utilities and large Utilities that also
model devices external to their Grid in their EMS SCADA & Network Databases, for improved
Grid reliability and operations.
Because Pegasus is 100% “Managed Code” executing on Microsoft’s latest .NET Framework,
Pegasus can be easily migrated to the latest Microsoft Platforms, Tools, and Operating Systems
for many years to come. The .NET Framework is Microsoft’s Development Platform of choice for
the next several years. Also, because Pegasus does not require any specialized hardware nor
specialized Operating Systems (or Operating System Extensions), Pegasus can take advantage of
newer, faster off-the-shelf hardware running the latest Microsoft Operating Systems.
