Configuring the Appliance Network
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.
Configuring Appliance Pools
This section describes design considerations to determine the most appropriate pool
configuration for the 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:
■
Use parity-based protection for general-purpose and capacity-optimized systems:
■
RAID-Z for protection from single-drive failure on systems subject to random
workloads.
■
RAID-Z2 for protection from two-drive failure on systems with streaming workloads
only.
■
Use mirroring for high-performance with incrementally applied backup.
■
Configure pools based on performance requirements:
■
Configure a single pool for management-optimized systems.
■
Configure two pools for performance-optimized systems. Two-pool systems should be
configured by using half the drives from each tray.
■
Configure log device protection:
■
Stripe log devices for RAID-Z and mirrored pool configurations.
■
Mirror log devices for RAID-Z2 pool configurations.
