Oracle Database Appliance• Traditional database
implementation– Installation of OS– Configuring for Oracle RAC– Installation of Oracle, patching– Mitigation of issues
Rise9of9the9Machines4
ODA is a packaged solution– 2 nodes– RAC Database– Storage Built-in– 4U Rackmounted Chassis

Specification• Each node has
– Two 6-core Intel Xeon processors X5675 – Cores licensed independently (pay-as-you-grow)– 96 GB of RAM– The cluster interconnect is via 1GbE (redundant)– Six 1GbE and two 10GbE external NIC ports– Runs Oracle Enterprise Linux 5.5

The Appliance
Rise9of9the9Machines6
• 20X 600 GB 15K SAS drives– 12 TB of raw storage – (triple mirrored; so 4 TB usable) for database alone. – FS on each server are for Linux OS and Oracle software.
• 4X solid state disks of 73GB each for redo logs• Appliance Manager Software
– database deployment, patching and health-checks• Patching the entire appliance I
– including O/S, firmware, Grid Infrastructure and Database

Good for• Organizations that don�t have a large staff to deploy and
administer databases• Small or medium databases where RAC is essential• Smaller upfront investment• It�s not a mini-Exadata
– doesn�t have all the software Exadata has

Unique Features• Smart Scan
– select col1 from table1 where col2 = 2
– filtering done at storage level• Storage Indexes
– Store the min and max values of data on the storage cells• Flashcache• Infiniband

Good for• A super efficient database machine
– Database alone– The filesystem space on compute nodes is very little– Usually for other software such as GoldenGate– DBFS � a cluster filesystem, for ETL input files
• Great for datawarehouses– Smart Scan
• Not so great for OLTP– Flashcache helps
• Migration from Oracle based databases is super easy
