How to connect hardware to SAN Swithes in terms of fault tolerance and bandwidth usage

Good day!
There are two SAN fabrics:
SAN fabric 1: 'HP Blade System SAN Switch-1' + 'HPE SN3600B FC Switch-1'
SAN fabric 2: 'HP Blade System SAN Switch-2' + 'HPE SN3600B FC Switch-2'

VMware ESX servers and NetApp2750 datastore are connected to SAN switches.
The datastore contains virtual machines, this storage NetApp2750 consists of two nodes, each node has two FC-dapters.

Server ESX-01, Server ESX-02, Blade System SAN Switch-1, Blade System SAN Switch-2 are included in the HPE Blade Enclosure.

How to connect hardware more correctly in terms of fault tolerance and bandwidth usage:
like Sample-1 or Sample-2?

SAMPLE-1:

SAMPLE-2:

Re: How to connect hardware to SAN Swithes in terms of fault tolerance and bandwidth usage

Hi KPN,

I see that you would like to know which fabric configuration is best for fault tolerance and bandwidth from the SAN topology diagrams provided ( SAMPLE1 and SAMPLE2 ).

I would always suggest that you go ahead with the configuration mentioned in Picture named "SAMPLE-1". As per this configuration, HOPS are same from server to storage on all paths.  Two fabrics provide fabric level redundancy as well.  All the connections on servers and storages are redundant.   I would also suggest that you add one more link from blade switch to external switch SN3600B in each fabric (In case of SAN Fabric 1- Add one more link from Blade System SAN Switch-1 to HPE SN3600B FC Switch-1. In case of SAN Fabric 2- Add one more link from Blade System SAN Switch-2 to HPE SN3600B FC Switch-2 )

Thank You!
