Interpath Technology Saves Client Millions of Dollars per Day in Lost Financial Transactions

 

Server consolidation & Virtualization save a great deal of money in total cost of ownership & capital equipment.  However, it seldom goes smoothly.  Server Consolidation & Virtualization can also cost big money in lost productivity - vendor costs - damage to an IT Manager's reputation. 

Co-hosted environments - Virtualization, - Server Consolidation - collapses several different servers into one.   Interpath Technologies recommends a "stitch in time" approach with Single Transaction Analysis for Pre-Production & Parallel Production builds.  Load testing is not enough.  Single transaction analysis - before production deployment - is critical.  Countless applications pass load testing only to fail in production.  Single Transaction Testing will discover problems early & easily.

A large Financial Organization underwent a relatively small server consolidation from an outdated system to a cluster of fast Servers on FiberChannel.  After cut-over, new system began to lose transaction at a very alarming rate.  A very high profile project - an expensive problem - costing millions of dollars per day - in lost financial transaction.  Vendor worked this problem for several days with no improvement. 

Client engaged Interpath Technologies Corporation to perform an Enterprise Transaction Analysis. 

 

We designed a systematic approach - we examined all possible pathways - not just those designed by Vendor or those that were expected.  It isn’t an inspired process - just a thorough one.  We discovered - Oracle based traffic from lost transaction - which should have been exclusively in FiberChannel - on a 100Mbs Half Duplex copper segment!  Data had been falling into "bit bucket."  Once problem was understood, they reconfigured network interfaces - no further transaction were dropped.
