1.8.2 Data protection and retention for SAN Boot In addition to increasing storage efficiency, we need to focus on data protection as well: ► Requirements to ensure that data is protected from disaster ► Demand that data be continuously accessible ► The need to adhere to business and legal requirements In this section, we look at how SAN Boot implementations using IBM disk storage systems and IBM storage software solutions can help storage administrators and CIOs win the data war. Backup and recovery You back up your data so it can be recovered or restored in case of data loss or corruption. Your business cannot afford not to have key data available. But ongoing data growth places more and more demands on backup processes. Solutions IBM offers a wide range of effective, efficient, and secure backup and recovery solutions to ensure that key business information is always available. IBM Tivoli Storage Manager IBM Tivoli Storage Manager enables you to protect your organization’s data from failures and other errors. It does so by storing backup, archive, space management, and bare-metal restore data, as well as compliance and disaster-recovery data, in a hierarchy of offline storage. You can take advantage of a SAN Boot host solution using both IBM disk storage systems and IBM Tivoli Storage Manager. Thus, host backup and recovery processing benefits from high performance disk storage and advanced functionality such as FlashCopy to securely and efficiently meet ever demanding backup and recovery requirements. Continuous operations According to recent research, a one-hour IT system outage can cost a business $1.1M. Your IT systems must be able to prevent and avoid outages and recover from them quickly, Solutions IBM offers a range of reliable, high-performance solutions to ensure that a business can remain operational through component failures or significant disasters. IBM Tivoli Storage FlashCopy Manager Use of IBM Tivoli Storage FlashCopy Manager enables organizations to perform and manage frequent, near-instant, non-disruptive, application-aware backups and restores, making use of advanced FlashCopy snapshot technologies in IBM storage systems. Just as IBM Tivoli Storage FlashCopy Manager takes advantage of IBM storage systems functionality, so can SAN Boot host solutions utilizing IBM storage systems. With the ability to take instantaneous FlashCopies of a host operating system, costly issues, which might be encountered with newly applied operating system or application code, can be quickly restored. By centralizing the location of the host operating system storage with use of SAN Boot, System Administrators are also able to rapidly recover from host hardware errors. By simply re-assigning SAN Boot volumes to standby hardware, recovery times and outage costs are greatly reduced. 18 SAN Boot Implementation and Best Practices Guide for IBM System Storage
Control and automation By automating management and enforcement of storage policies, you can keep storage infrastructure in its desired state efficiently. It can help you improve service quality, improve data protection, recovery, reliability, and integrity while reducing ongoing staff intervention. Solutions Automated lifecycle management tools can help you meet information retention mandates, automate provisioning, backup, and archive to optimize performance, utilization, lower costs, and build agility. IBM Tivoli Storage Productivity Center IBM Tivoli Storage Productivity Center Standard Edition is a single integrated solution designed to help you improve your storage TCO and ROI by combining the assets, capacity, performance, and operational management, traditionally offered by separate Storage Resource Management, SAN Management, and Device Management applications, into a single platform. Implementing a SAN Boot host solution in conjunction with IBM Tivoli Storage Productivity Center can further improve and facilitate Storage Resource Management. By co-locating host operating storage on IBM storage systems, numerous benefits can be realized: ► Capacity can be monitored at the storage system level, not at the individual host level. ► Automation can be implemented to create capacity on demand storage solutions. ► Overall storage utilization can be planned for at the storage subsystem level. Retention and compliance Today, significant amounts of data must be saved to meet business or legal requirements. Solutions As the amount of information stored grows and grows, effective data archiving solutions can help you improve productivity, control both infrastructure and legal costs, and manage compliance and operational risks. IBM Information Archive IBM Information Archive is a simple and flexible archiving solution to help organizations of all sizes address their complete information retention needs: business, legal, or regulatory. With a SAN Boot host solution, retention is enhanced by the functionality of the IBM storage system that the data resides on. Use of centralized storage subsystem functionality, instead of utilizing a mixture of functionalities found with individual host level storage, reduces administrative overhead. In regard to compliance, SAN Boot host data can benefit from FlashCopy snapshots of data and the retention of that data in a locked and immutable state, pending movement to an archive environment such as IBM Information Archive.
