Upgrading a DDR Fabric Board to a QDR Fabric Board

Upgrading a DDR Fabric Board to a QDR Fabric Board

Upgrading a DDR Fabric Board to a QDR Fabric Board involves removing the existing Fabric
Board from the Fabric Interconnect and replacing with the new QDR Fabric Board. The Fabric
Board is not hot swappable, so you will need to power down each Fabric Interconnect that will
receive the QDR Fabric Board.
For the upgrade, you will need the following equipment:
#2 Phillips (cross-head) screwdriver
■
an ESD wrist strap
■
an ESD-safe workspace for the Fabric Boards when they are not in the Fabric Interconnect.
■
The ESD bag that ships with Oracle modules is an option if a grounded workspace is not
available.
Note -
performing the hardware upgrade.
Some considerations exist for upgrading a DDR Fabric Board to a QDR Fabric Board:
The QDR Fabric Board has 20 ports instead of the 24 ports on the DDR Fabric Board. Due
■
to the difference in number of ports, data centers that use an SNMP management tool can
experience port index number problems (portIfIndex). If your data center uses an SNMP
Management tool, you will need to rediscover the devices through the SNMP manager to
correctly enumerate the devices' port IDs.
Also, due to the different number of ports on the QDR Fabric Board, you might need to "fan
■
out" the IB network. For example, if your existing DDR Fabric Board has full deployment
of 24 servers, the servers connected on ports 21 through 24 cannot be connected directly to
the 20-port QDR Fabric Board.
To reconnect the servers that were on ports 21 through 24, you will need to connect an IB
expansion switch to one of the ports on the QDR Fabric Board. This IB expansion switch
will then fan out the IB network, and allow you re-connect the servers that were on ports 21
through 24 of the DDR Fabric Board.
When the new Fabric Board boots up, QDR fabric ports are brought online at QDR rate if
■
QDR HCAs are installed in the connected servers.
No license key is required to activate the 40 Gbps QDR fabric.
■
To support the QDR Fabric Board, the Fabric Interconnect must be running XgOS version
■
3.0 or later. There is no minimum firmware version required on the HCAs, but you should
always use the latest version of firmware recommended by Oracle.
