VMware

I need information or list of questions to ask vendor that installed our medical Imaging (PACS) on How their VMware 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.

ask them for the specification of the Virtual Machine, also ask how the SAN datastores have been configured, and what topology?

what testing has been performed and signed off?

I woul also ask for documented tests and benchmarks that have been recorded.

"database, application and SAN" makes me think:

1. Disk speed (RPM) 7,500 vs 10k or faster
2. NIC speed  100M vs 1G
3. RAM How much

as places to begin the research.

As a fellow profession with PACS on site can I ask what your hardware infrastructure is? What servers is PACS hosted on? Virtualised on VMWare? What is your SAN make/model? Disks?
Is it just SAN or DAS also?

As much info as you can give will help us to diagnose where problems may lay.

All very pretty but if you start off by answering the questions we ask, we might get somewhere a little quicker.

You probably don't need a list of questions, just a list of disks in use in system previously and those in use now to give to us. Then we may be able to suggest the obvious question to ask them "did you honestly expect this to work when it has half the IOPS of the previous setup" although I won't be posting since I've just looked at your grading record.
