From a vSphere perspective, what is latency? What is good latency?

[vmmedmed]

On the network side of the house - latency it most commonly used

in reference to ICMP ping rtt. But in VMWare vSphere what exactly

is being measured if I go to Server/Monitor/Performance/Overview

and look at the section "Disk"? It's clearly not the rtt which is

about 1ms at most in the data center. Is it time it takes to

read or write to the disk? How do you determine if this

latency is smokin' fast or nor very good? Are there vmware

utilities that provide a deep analysis of disk performance?

Thank you.

You can use VMware esxtop Command. Refer my below blog.

Hi there, in a perpective of latency in storage you can check this links:

Hope that helps!
