Configure Appliance

Manual Configuration of a Sun ZFS Storage Appliance

This section provides general guidelines for manually configuring a Sun ZFS Storage Appliance for use with the Oracle Exadata. For detailed information, see the Protecting Oracle Exadata with the Sun ZFS Storage Appliance: Configuration Best Practices white paper on the Sun Unified Storage Documentation page.

Configuring Networks, Pools, and Shares

The following sections summarize best practices for optimizing Sun ZFS Storage Appliance network, storage pool, and share configurations to support backup and restore processing.

Network Configuration

This section describes how to configure the IP network multipathing (IPMP) groups, and how to configure routing in the Sun ZFS Storage Appliance.

Note: If you used the Oracle Exadata Backup Configuration Utility, configure the network as described in this section. For details, review the Best Practices white paper.

The basic network configuration steps are:

  1. Ensure that the Sun ZFS Storage Appliance is connected to the Oracle Exadata.

  2. Configure ibp0, ibp1, ibp2, and ibp3 with address 0.0.0.0/8 (necessary for IPMP), connected mode, and partition key ffff. To identify the partition key used by the Oracle Exadata system, run the following command as the root user:# cat /sys/class/net/ib0/pkey

  3. Configure the active/standby IPMP group over ibd0 and ibd3, with ibd0 active and ibd3 standby.

  4. Configure the active/standby IPMP group over ibd1 and ibd2, with ibd2 active and ibd1 standby.

  5. Enable adaptive routing to ensure traffic is load balanced appropriately when multiple IP addresses on the same subnet are owned by the same head. This occurs after a cluster failover.

For customers seeking additional IB connectivity, more IB HCAs can be installed and configured. For details, see the Sun ZFS Storage 7x20 Appliance Installation Guide.

The principles in this section can be applied to a 10Gb Ethernet implementation by applying the network configuration to the ixgbe interfaces instead of the ibp interfaces. The 10Gb Ethernet implementation may be configured as active/active IPMP. If the Sun ZFS Storage Appliance is on a different subnet than the Oracle Exadata, it may be necessary to create static routes from the Sun ZFS Storage Appliance to the Oracle Exadata. Consult with your network administrator for details.

Pool Configuration

This section describes design considerations to determine the most appropriate pool configuration for the Sun ZFS Storage Appliance for Oracle Recovery Manager (RMAN) backup and restore operations based on data protection and performance requirements.

Note: If you used the Oracle Exadata Backup Configuration Utility, configure the pool as described in this section. For details, review the Best Practices white paper.

The system planner should consider pool protection based on the following guidelines:

Note: If you used the Oracle Exadata Backup Configuration Utility, proceed to the next topic: Configuring Oracle Exadata for a Sun ZFS Storage Appliance.

Share Configuration

The default options for Sun ZFS Storage Appliance shares provide a good starting point for general-purpose workloads. Sun ZFS Storage Appliance shares can be optimized for Oracle RMAN backup and restore operations as follows:

Additional share configuration options, such as higher-level gzip compression or replication, can be applied to shares used to support Oracle Exadata backup and restore, as customer requirements mandate.

Customers implementing additional Sun ZFS Storage Appliance data services should consider implementation-specific testing to verify the implications of deviations from the practices described earlier.

Configuring Oracle RMAN and the Oracle Database Instance

Oracle RMAN is an essential component for protecting the content of Oracle Exadata. Oracle RMAN can be used to create backup sets, image copies, and incrementally updated backups of Oracle Exadata content on Sun ZFS Storage Appliances. To optimize performance of Oracle RMAN backups from Oracle Exadata to a Sun ZFS Storage Appliance, the database administrator should apply the following best practices:

To optimize buffering of the Oracle RMAN channel to the ZFS Storage Appliance, you can tune the values of several hidden instance parameters. For Oracle Database 11g Release 2, the following parameters can be tuned:

For additional information about tuning these parameters and tuning equivalent parameters for earlier versions of the Oracle Database software, see Article ID 1072545.1: RMAN Performance Tuning Using Buffer Memory Parameters) at http://support.oracle.com.

Oracle Direct NFS (dNFS) is a high-performance NFS client that delivers exceptional performance for Oracle RMAN backup and restore operations. dNFS should be configured for customers seeking maximum throughput for backup and restore operations.
