I have a question in regards to some issues we’ve been experiencing. We have a server running around 10 different projects and controlling Vision clients on various machines. We’ve been noticing some pretty sever lag spikes around the facility (sometimes 20+ seconds). We haven’t had any of the HMI screens come up with Gateway errors, it just seems to be weird behavior with the HMI screens themselves. It’s not related to a specific project. We’ve also checked PLC load, client hardware and network traffic and none of those seem to be related to the issue. I think at this point, this post is my only clue:
The server we are using has mechanical SCSI drives in it running in RAID 1. Is it a possibility that the mechanical drives are the cause of this issue we’ve been experiencing? I’ve checked drive health, and all seems to be good, but because project files are stored on the drive, it seems to be the only thing I can really think of.
Would anybody have any suggestions?
