vSphere 6.5 - Round Robin LB Settings (changing iops=1000 to iops=1)

Hi all!

I have bought HP MSA 2052 recently and using it with ESXi 6.5 host. I read "HPE MSA Storage Configuration and Best Practices for VMware vSphere" documentation and there is one section 

"Multipath
With server virtualization environments using vSphere 5.x, HPE recommends using the Round Robin (VMW_PSP_RR) failover policy with all HPE MSA Storage arrays. For optimal default system performance with HPE MSA Storage, configure the round robin load balancing selection to IOPS with a value of 1 for every LUN"

My question is does this settings still valid to 6.5?

Hi,

Yes, for vmware version 5.x or higher, it is suggested to have multipathing policy as Round Robin (VMW_PSP_RR)

and IOPS with a value of 1 for every LUN. This is applicable for vmware 6.5 as well.

"configure the round robin load balancing selection to IOPS with a value of 1 for every LUN"

I can find the "Edit Multipathing" option in the VMWARE web client (Under Storage Devices/Select the DataStore/Porperties"

From there I can select "Round Robin"

Where is the "IOPS with a value of 1" set?

Command 1:  to check the current setting as we can see its 1000

# esxcli storage nmp psp roundrobin deviceconfig get -d naa.60002ac0000000000000162200004210

   Byte Limit: 10485760

   Device: naa.60002ac0000000000000162200004210

   IOOperation Limit: 1000

   Limit Type: Default

   Use Active Unoptimized Paths: false

 

Command 2:  to set  IOPS to 1

# esxcli storage nmp psp roundrobin deviceconfig set -d naa.60002ac0000000000000162200004210 --iops 1 --type iops

 

Hope this helps!
