7.1.2 Supported switches for zoning
For TotalStorage Productivity Center for Fabric to be able to perform zone changes to a SAN
fabric the switch hardware will need to be supported. The following link takes you to the latest
device compatibility page for devices supported by TotalStorage Productivity Center for
Fabric:
http://www-306.ibm.com/software/sysmgmt/products/support/IBM_TSANM_Device_Compatibility.html
Figure 7-1 TotalStorage Productivity Center for Fabric device compatibility Web page
Either scroll down this page to the Switches section or jump directly to it as shown in
Figure 7-1. If the switch you plan to use is not listed or is not a re-branded equivalent to one
listed then it is not supported by TotalStorage Productivity Center for Fabric.
Locate the switch you plan to use and click on it to view the detailed breakdown of its
functional support. Figure 7-2 on page 335 shows a device support details page. If you see a
Yes either in Zone Control Supported (either In-band or Out-of-band) then TotalStorage
Productivity Center for Fabric will be able to work with TotalStorage Productivity Center for
Disk to perform zone administration at LUN allocation and assignment time.
Important: Do not assume that a switch will support zoning changes just because it
appears on the device compatibility Web page. Not all switches support all functions that
TotalStorage Productivity Center for Fabric can provide so it is important to look at the
specific details of the device you plan to use.
334 Managing Disk Subsystems using IBM TotalStorage Productivity Center
There are two methods by which TotalStorage Productivity Center for Fabric can
communicate with a switch to effect zone changes. The method used is determined by the
switch vendor.
In-band method: This means that a switch accepts zone change control information
through instructions sent to it through the fibre channel network (in-band).
Out-of-band method: This means that a switch accepts zone change information through
instructions sent to it on its IP network interface know as out-of-band.
Important: For switches that use the in-band zone control method you will need to deploy
at least one TotalStorage Productivity Center for Fabric agent on a server that is fibre
connected to the SAN fabric you want to control.
For switches that use the out-of-band zone control method the TotalStorage Productivity
Center for Fabric manager machine talks directly to the switch over TCPIP and no agents
are required to implement this function.
The out-of-band method will require SNMP network access between the TotalStorage
Productivity Center for Fabric manager machine and the SAN switch. It may be necessary
for an organization to make firewall or network changes to allow this to take place.
Out-of-band is the simpler than In-band to setup because it does not require and agent on
a SAN connected host.
If you establish that an in-band agent will be required to perform zoning change with your
switch and you currently don’t have in-band agents there are a number of things to
consider. A TotalStorage Productivity Center for Fabric agent will need more IP ports than
SNMP to communicate with the Fabric server and will require CPU, RAM and disk
resources on the SAN connected server.

redbook IBM TotalStorage Productivity Center - Getting Started, SG24-6490.
