Check the resources and performance of your infrastructure.

Increase the performance of your datastore, or decrease the number of VMs on the datastore.

BUT is this Alert present ALL the time, or just blips!

Check my EE Article, and learn how to identify performance bottlenecks

HOW TO:  Performance Monitor vSphere 4.x or 5.0

This message just came up when I moved all the virtual machines from the old current host . How do I increase the performance of my data stores ?

So compare the old host datastore setup with the new host datastore setup.

Old host are decommissioned. Is there a setting that I can change ? I thought drs and ha would fix the issue . I thought about restarting the virtual machines
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
So you have no idea or any documentation of what hardware configuration the old hosts had, and cannot compare that hardware with the new hardware.

RAID type, number of disks, speed of disks, server RAM or CPU ?

Configuration of vSphere, VMware HA or DRS are not going to help you.


Do you have this alert ALL the time ?

This alert just happened . I will go look at other host to compare. I just want these error messages to go away .  When the old host were turned on I didn’t get any kind of error messages . When I moved all virtual machines to the new 4 host I got this error message on 3 vms
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
we would expect if loading your datastore you would get alerts, if moving 3 VMs concurrently, the question is, does this alert happen all the time, or is it normal baseline activity.

Are these alerts still occurring, or was it only when you moved VMs to this datastore, this could be normal activity and nothing to worry about, and you'll not see alerts again.

Monitoring Alerts is all about understanding what is normal behaviour for your environment, and if you get an alert can you work out what cause it ?

in this case, you moved three VMs to a datastore, and got an alert!

So...you know what caused the alert, but does this alert impact performance of any services ?

did you ever move the same three VMs to the old host and get an alert ?

Just because you got a single alert does not mean, PANIC stations....

Validate that the datastore that has the host associated, have enough space to store those 3 vm, otherwise it increases the capacity of your datastore.

Are the alarms still appearing?
