MSA 2050 Jumbo Frame 'issue' - Best Practice guide wrong?

[IT-Dreamer]

Hello All

We have an MSA 2050 connected through it's own VLAN, via a HPE FF5700 to 5 HPE Gen10 ESX 6.7 servers.

We have created the datastores in VM on the SAN.

I have read the best practice guide for the MSA which states the Jumbo frame size should be set to a maximum of 8900.

If we set this, on all relevant interfaces and devices, we can see the datastores but have no write access to them from ESX.

If we set the jumbo frame to 9000 we have full access with read and write to the datastores.

Can someone please explain why? Am i missing something? It works with 9000 but not 8900

Thanks

Jumbo frame can contain a maximum of 9000 bytes for larger data transfers.
We have tested this in our labs , with the frame size set to 8900. 

If you have issues  when the value is set at 8900 , I would recommend you log a case with the support team to have further details checked..
