HP SAN

I need information or list of questions to ask vendor that installed our medical Imaging (PACS) on How their SAN is configured for optimization that would provide optimal performance.

Medical Imaging department is not satisfied with their system and it has been a chronic issue.

Back end bottleneck have been identified as database, application and SAN. No Network latency. All have been shown to be related to application delays.

One would assume that you have less disk IOPS available than before since computers are 4 times as fast as 3 years ago but disks are the same speed as before. What were the specs of the old systems including disk layout and what do you have now in place of it? Presumably people weren't complaining about poor preformance previously.

have you accurate measurements of all the particulars ? They need hard figures not 'it seems slow'. Where exactly are the bottlenecks? Unless you can answer these questions then contacting the vendor will be a waste of time as they will ask for the same details.

I am attaching our finding for review and suggesting on how to come up with a tacticle approach with the PACS vendor.

connection resets - check the cabling.  Run a performance test on the SAN, are you storing the images in a database? if so then check the database performance. Solarwinds has a lot of free trial programs that can assist you.

Please ask admin to unaccept answer, you haven't given us enough info yet and I was simply asking for more spec on your old and new system.
