Problems Today<br />

Microsoft Firewall clustering<br />
does between not provide <strong>PI</strong><br />
effective redundancy and<br />
Way<br />
ACE<br />
too many <strong>for</strong> things<br />
either <strong>PI</strong> running<br />
limits or ACE on the same<br />
throughput<br />
cluster. Resources<br />
become strained.<br />
Firewall allows access<br />
to the <strong>PI</strong> d<strong>at</strong>a server,<br />
not just the proxy<br />
service.<br />
Multiple connections<br />
needed to each PMU.<br />
Uses double<br />
bandwidth.<br />

Developing a roadmap<br />
� Numerous items to address in the current<br />
architecture<br />
� Still looking <strong>for</strong> the money tree, so prioritiz<strong>at</strong>ion<br />
is needed<br />
� Need to align with the <strong>OSIsoft</strong> product<br />
development roadmap<br />
� <strong>WAMS</strong> is evolving as a technology<br />
� The requirements <strong>for</strong> the infrastructure are a moving<br />
target<br />

Additional Improvements<br />
� Additional tuning of d<strong>at</strong>a exception and<br />
compression specific<strong>at</strong>ions<br />
� Notable improvements have been seen already with<br />
little to no loss in actual usable in<strong>for</strong>m<strong>at</strong>ion<br />
� Move primary d<strong>at</strong>a stores to an enterprise<br />
class SAN storage system (HP EVA system)<br />
� Possible addition of primary interface node <strong>at</strong><br />
the subst<strong>at</strong>ion<br />

Overall benefits<br />
� P<strong>at</strong>h <strong>for</strong>ward <strong>for</strong> <strong>Entergy</strong><br />
aligns with <strong>OSIsoft</strong><br />
development roadmap<br />
� “Horizontal” scalability where<br />
possible allows the use of<br />
commodity hardware<br />
� <strong>PI</strong> pl<strong>at</strong><strong>for</strong>m components<br />
largely centrally managed<br />
� Additional division of duties<br />
among more servers allows<br />
<strong>for</strong> multiple security zones<br />

� High availability provided by<br />
applic<strong>at</strong>ion n<strong>at</strong>ive services,<br />
r<strong>at</strong>her than MS clustering<br />
� Separ<strong>at</strong>ion between realtime<br />
control room d<strong>at</strong>a use,<br />
intense analytics, and large<br />
report queries<br />
� Potential reduced WAN<br />
bandwidth requirements<br />
(subst<strong>at</strong>ion PC and/or 37.118<br />
server needed to fully<br />
realize)<br />
