We have 3 netapp disks bays on our site.
Is it a good practice when we create one zone, to put
multiple bays controllers and one HBA host ?
Should we instead create 3 zones ? On each zone we would have one baie and the HBA host ?
It's easier to create one zone, instead 3 zones, but technically, is there known troubles
with communication, synchronisation, performance on san ?
It there a PDF with good practice with san administration ?

As security reason, i would create 3 Different Zone.

Read this for knowing best practice for zoning.

are you running single NetApp filer head or clustered systems?
Which model are you using and how many target and initiator ports are in your system.
NetApp recommends to use dedicated cards as initiators for disk shelf attachment which are not connected to the SAN and the onboard ports as targets ports.
Onboard cards 0a and 0b are within the same ASIC. 0c and 0d share another ASIC. If you have dual fabric design connect 0a and 0b to fabric 1 and 0c and 0d to the second fabric.
If you have a dual fabric design and the servers are connected to both fabrics I prefer to zone like following example:
zone 1: server1_1, NetappA_0a
zone 2: server1_1, NetappB_0a
zone 3: server2_1, NetappA_0b
zone 4: server2_1, NetappB_0b
zone 1: server1_2, NetappA_0c
zone 2: server1_2, NetappB_0c
zone 3: server2_2, NetappA_0d
zone 4: server2_2, NetappB_0d
NetAppA and NetAppB are configured as a Cluster in Single Image mode. All servers are using NetApp MPIO package or the DSM module.
Take care that you are not using the proxy pathes to access the LUNs within the filer. This will slowdown the performance.
