4 Maintaining Other Oracle Exadata Components

Besides the database and storage servers, Oracle Exadata contains other components, such as power distribution units, ILOM, and network switches.

Note:

• All procedures in this chapter are applicable to Oracle Exadata and Oracle Exadata Storage Expansion Rack.
• For ease of reading, the name "Oracle Exadata Rack" is used when information refers to both Oracle Exadata and Oracle Exadata Storage Expansion Rack.

• Replacing a Power Distribution Unit
  
• Resetting a Non-Responsive ILOM
  
• Configuring Service Processor and ILOM Network Settings
  
• Verifying and Modifying the Link Speed on the Client Network Ports for X7 and Later Systems
  You can configure 10 GbE connections or 25 GbE connections on the client network on Oracle Exadata X7 and later database servers.
• Verify the Link Speed on Network Ports
  Ensure you are using the correct link speed for Oracle Exadata Database Machine X7-2 compute nodes.
• Changing from 1 GbE Connections to 10 GbE Connections
  1 GbE network connections can be changed to 10 GbE connections.
• Maintaining the RoCE Network Fabric
  The RoCE Network Fabric connects the database servers and Exadata Storage Servers through the bonded interface to the RoCE Network Fabric switches in the rack.
• Maintaining the InfiniBand Network Fabric Network
  The InfiniBand Network Fabric network connects the database servers and Exadata Storage Servers through the bonded interface to the InfiniBand Network Fabric switches in the rack.
• Modifying the InfiniBand Network Fabric Configuration
  You can change how the InfiniBand Network Fabric network is configured by changing the IP addresses or host names, or by implementing partitioning.
• Configuring Network Routing on Database Servers
  The tasks for network routing are for boot-time routing or real-time routing.
• Changing the DNS Servers
  The configuration settings for the Domain Name System (DNS) servers can be changed after initial setup.
• Changing the NTP Servers
  The configuration settings for the Network Time Protocol (NTP) servers can be changed after initial setup.
• Changing the Time Zone Settings
  You can change the time zones on Oracle Exadata after initial configuration and deployment.
• Managing the KVM Switch
  The KVM switch is only available in Oracle Exadata Database Machine X2-2 racks and Oracle Exadata Storage Expansion Racks with Exadata Storage Server with Sun Fire X4270 M2 Servers.
• LED Status Descriptions
  The LEDs on the Oracle Exadata Rack components help you identify the component that needs servicing.
