FICON best practices for Virtual Fabrics

NOTE
In the 8-slot Backbone Chassis, ports 48–63 of the FC 8 GB 64-port Blade are not supported in the
base switch, and ports 56–63 are not supported as E_Ports on the default logical switch. The 4-slot
Backbone Chassis does not have these limitations.
FICON best practices for Virtual Fabrics
Use the following recommended best practices and considerations for configuring Virtual Fabrics in
a FICON environment when following the procedures under
•
When configuring the logical switch in the New Logical Fabric Template or New Logical Switch
dialog box (Fabric tab), use the following parameters. Note that the New Logical Fabric
Template dialog box creates a fabric template. You can always rename the fabric and change
parameters after the new fabric is created.
-
Logical Fabric ID (FID) – Use any FID as long as all switches in a fabric have the same
Fabric ID. The default Fabric ID for the default switch is 128, which leaves 1 through 127
for newly created fabrics.
-
256 Area Limit – “Disabled” is not supported for FICON. As a recommended best practice,
use “Zero Based Area Assignment” as this will work for any configuration.
-
R_A_TOV, E_D_TOV, WAN_TOV, Maximum Hops, BB Credit, Data Field Size – Do not change
these parameters unless otherwise directed by your switch service provider. Any change to
these parameters is a rare case.
-
Interoperability Mode – With Fabric OS 7.0.0 and later, only “Brocade Native” mode is
supported, so this parameter cannot be changed.
-
Base Switch or Base Fabric for Transport (XISL) - Do not select these check boxes as they
are not supported for FICON.
-
Sequence Level Switching, Per-Frame Routing Priority, Suppress Class F Traffic – Do not
select these check boxes.
