One san zone with multiple disks baies and one host ?

Hi,

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 ?

Thanks.

Patrick LAURENT.

As security reason, i would create 3 Different Zone.

See the Fabric OS Administrator Guide

Thanks for your answers.

We will try to change our zones and place one bay and one host in a zone.

Re: One san zone with multiple disks baies and one host ?

Hello Patrick,

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:

Fabric 1

zone 1: server1_1, NetappA_0a

zone 2: server1_1, NetappB_0a

zone 3: server2_1, NetappA_0b

zone 4: server2_1, NetappB_0b

Fabric 2

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.
