Note: A mix of SAN Client job loads where some clients use four or more FT pipes
concurrently with several other SAN Clients that only attempt to use a single FT
pipe at a time increases the odds that a higher –ncp setting may cause FT media
server imbalance.
For four gBit/s links, there may be situations where overall throughput can degrade
when some or all SAN Clients are using multiple concurrent data streams. This
scenario may be especially true for NetBackup 5220 appliances. In those situations,
nbftconfig –setconfig –ncp 3 may be a better option.
Configuring Fibre Transport for optimized
duplication and Auto Image Replication over FC
Table 4-4 provides an overview of how to configure Fibre Transport(FT) on the
appliance for optimized duplication and Auto Image Replication over FC.

FT configuration process for optimized duplication and Auto Image
Replication over FC
DescriptionActionStep
Identify your appliance HBA configuration.
See “About the NetBackup 5230 rear panel configurations”
on page 18.
See “NetBackup 5240 Appliance I/O configuration options”
on page 20.
See “NetBackup 5330 Appliance compute node PCIe slot I/O
configuration options” on page 23.
Determine whether your appliance HBA configuration supports FT
for optimized duplication and Auto Image Replication.
See “About Fibre Channel feature support with appliance HBA
configurations” on page 14.
Determine whether your appliance
HBA configuration supports FT for
optimized duplication and Auto Image
Replication.
Note: The HBA configuration of 53xx
C and 5240 H support optimized
duplication and Auto Image
Replication over FC, but can only
support using the appliance as a
source.
Step 1
See “About Fibre Transport for optimized duplication and Auto Image
Replication between appliances” on page 11.
Learn about FT for optimized
duplication and Auto Image
Replication.
Step 2
See “About FTMS reserved HBA ports and the factory default port
mode configuration” on page 32.
Learn about default HBA port mode
for optimized duplication and Auto
Image Replication over FC.
