ESXi Storage performance issues

I’m running ESXi on a Dell server, with four SSDs in raid 10. The ESXi is hosting 6 RedHat VMs which are running java applications. Lately, I’ve been running into some storage performance issues. Can I do something to tune any parameters at storage level in ESXi?

  1. Hi,

    Have you consulted the VMWare performance white paper? As in you’re using Paravirtual SCSI (if supported with the OS) that’ll improve performance by consuming less CPU. As the SSD’s are in RAID, does ESXI detect the RAID array as flash storage? It may not be using it optimally if it’s treating it as HDD
