About Attaching and Cabling Storage Shelves
Review these options and best practices for adding storage shelves for Oracle
Database Appliance X6-2-HA.
Storage Shelf Options for Oracle Database Appliance X6-2-HA
Oracle Database Appliance X6-2-HA can be shipped with one or two storage shelves.
You can obtain the second shelf at a later time to double your storage capacity.
If you originally deployed Oracle Database Appliance with one storage shelf, then you
can add a storage expansion shelf at any time without having to shut down your
databases or applications.
Best Practice Guidelines for Adding Storage Expansion Shelves
Oracle recommends that you add a storage expansion shelf when you have relatively
little activity on your databases. When the system discovers the new storage, Oracle
ASM automatically rebalances the disk groups. The rebalance operation may degrade
database performance until the operation completes.
Caution:
Review cabling instructions to ensure that you have carried out cabling
correctly. Incorrect connections can cause data loss when adding a storage
expansion shelf to Oracle Database Appliance with existing databases.
Do not attach cables to Ethernet ports in the I/O modules labeled "SERVICE
ONLY" when cabling the system. These ports are intended for use by service
engineers only.
How to Cable a Storage Expansion Shelf
The following figure shows you how to insert the required cables into the storage
expansion shelf of Oracle Database Appliance. The cables for the two nodes and the
original storage shelf are included in the illustration for reference.
The cables are color-coded. Match the colors of the labels at the ends of each cable
with the colored line shown in the illustration. Also match the cable colors to the
background colors of the socket identification labels. You can also use the callouts in
the diagram to identify the cables and ports. Because all cables with the same
terminations are interchangeable, you can ignore the color coding. The back panel of
each node contains three PCIe generation 3 terminal slots, with two sockets in each
slot. The PCIe slots are labeled X PCIe3, where X is the PCIe slot number. Review the
callout table that follows the figure for more information.
