Chapter 7: Conclusion Chapter 7: Conclusion Overview Introduction to conclusion This Proven Solution Guide details an Oracle infrastructure design leveraging an EMC CLARiiON CX4-960 array, EMC Data Domain DD880, and EMC NetWorker. Also included are various test results, configuration practices, and recommended specific Oracle storage design layouts that meet both capacity and consolidation requirements. This document describes many technologies that enable the benefits outlined below. Conclusion Traditional hardware compression provides substantial cost savings in Oracle environments. However, in this solution data deduplication significantly reduces the amount of data that needs to be stored over an extended period of time. This solution offers cost savings both from a management standpoint and in the numbers of disks or tapes required by a customer to achieve their long-term backup strategy. Data deduplication can fundamentally change the way organizations protect backup and nearline data. Deduplication changes the repetitive backup practice of tape, with only unique, new data written to disk, therefore the deduplicated backup image does not carry the restore penalty associated with incremental backups because the entire image is always available on the device. This eliminates the need for incremental restores. The test results show that, in an environment utilizing RMAN full backups, data deduplication ratio of over 13:1, resulting in a 92 percent saving in the storage required to accommodate the backup data, makes it economically practical to retain the savesets for longer periods of time. This reduces the likelihood that a data element must be retrieved from the vault and can significantly improve the RTO. Although cost savings are generally not the initial reason to consider moving to disk backup and deduplication, financial justification is almost always a prerequisite. With the potential cost savings of disk and deduplication, the justification statement becomes, “we can achieve all of these business benefits and save money.” That is a compelling argument. The solution meets the business challenges in the following manner: • Ability to keep applications up 24x7 • Faster backup and restores – meet more aggressive backup windows, and restore your key applications in minutes, not days • Reduced backup windows – minimize backup windows to reduce impact on your application and system availability • Protect the business information as an asset of the business • Reduced business risk – restore data quickly and accurately with builtin hardware redundancy and RAID protection • Reduced backup windows – minimize backup windows to reduce impact on your application and system availability EMC Backup and Recovery for Oracle 11g OLTP Enabled by EMC CLARiiON, EMC Data Domain, EMC NetWorker, and Oracle Recovery Manager using NFS Proven Solution Guide 76
Chapter 7: Conclusion • Efficient use of both infrastructure and people to support the business • Improved IT efficiency – save hours of staff time and boost user productivity • Correct costs / reduce costs – match infrastructure costs with changing information value via efficient, cost-effective tiered storage In summary, utilizing the solution components, in particular CLARiiON technology, EMC Data Domain, and EMC NetWorker software, provides customers with the best possible backup solution to prevent both user and business impact. Business can continue as usual, as if there is no backup taking place. In customer environments where, more than ever, there is a trend toward 24x7 activity, this is a critical differentiator that EMC can offer. Next steps EMC can help to accelerate assessment, design, implementation, and management while lowering the implementation risks and costs of a backup and recovery solution for an Oracle Database 11g environment.
