Hello,
I wonder what is a maximum number of datastores that I can create on single ESXi hypervisor? In vsphere-65-configuration-maximum there is section 'Storage Maximums' in chapter 'ESXi Host Maximums' , but I can't find the right number of datastore that can be created on a hypervisor.
In "vCenter Server Maximums" is stated: " Datastores 256" and "Hosts 21". Can I assume that I should be able to create 256/21 datastores on single ESXi?
Can someone explain it to me?
I have platform with 11 drives but I can create only 6 datastores. After seven I am getting: "Failed to create VMFS datastore ds7 - Cannot change the host configuration. "
What connection speed are you using ? I have used 1gug and had over 100. I believe its something like 1000+ paths.
Maximum number of datastores that you can create on single ESXi is 512. Please refer Page13 in your attachment.
Try to add 8th LUN, by connecting to ESXi directly using vSphere client and post the status.
Hi ,
Could you please share below information
Type of LUN - iSCSI / FC ?
Using vCenter or Only one ESXi host ?
How many path using to connect ?

I have two 1 gig network card.

Ok, thanks.
I am connecting to ESXi directly using vSphere client.
@RAJ_RAJRAJ_RAJ
Only ESXi host. Disk are SSD.
I think LUN is iSCSI.
How can I determine "How many path using to connect ?"
Hi ,
VMware MAX - iSCSI Physical LUNs per server 512 will support . Check that iSCSi LUN is allocated and provided required access from storage console .
Path you can check from data store , check below image (click on manage paths )
I am using direct web clinet to ESXi so I don't have this option.
Are you able to add new datastores, after connecting to ESXI directly using vSphere client?
How can I determine "How many path using to connect ?"
Hi,
Use CLI

I think upto 512 no. of datastore to be created on ESXi hypervisor. Does your storage is directly attached storage ?. Also it depends on the type of storage you using and storage protocol you used.
Yes it is
Also look for the below solution provided on video,
