About three months ago, we upgraded from View 5.2 to 6.2.2. We started seeing Persona issues almost immediately, and found that our VNXe CIFS share wasn't enough for Persona. I moved the Persona share to an older, but very capable DB server. The share is hosted on 6 1TB 7200 RPM NL-SAS drives, running Windows Server 2003 R2.
Since around the 6.2 upgrade, but more so since the Persona move, many people have complained about slow computers. The slowness comes and goes, seemingly with little reason, other than our login storm in the morning. I've looked into several things, including CPU Ready, Wait, Disk latency, etc, all are within VMware's recommendations. The only thing I could find amiss is that the drive that the Persona share lives on is pretty swamped at this point. According to perfmon the average write queue is in the 20s and the Disk time % is in the thousands.
That's bad, and I know it, but would a slow Persona share really tank performance system wide? Or is this a red herring?
