1 Helping provide nondisruptive dataset-level migrations for the mainframe environment IBM Data Mobility Services Softek LDMF With Softek LDMF software, datasets that reside on multiple smaller-capacity volumes can be combined onto one large-capacity volume. Maintains application availability during dataset-level migrations Provides the flexibility to immediately address storage utilization and application performance with load balancing and tiered storage Offers the ability to migrate to high-performance, largecapacity disks Highlights Helps eliminate time-consuming manual dataset-level migrations by providing a nondisruptive migration alternative Enables more rapid storage utilization Establishes unit control block (UCB) management through volume consolidation Streamlines large-scale migrations with the ability to group datasets Performing dataset-level migrations without affecting application availability Many IT organizations that are looking to take advantage of large-capacity volumes on today s high-performance storage subsystems are faced with complex and disruptive data migrations that can have a negative effect on business applications. But with IBM Data Mobility Services Softek LDMF (Logical Data Migration Facility) software, you gain access to the proven technology needed to consolidate data onto large-capacity, better-performing storage volumes without interrupting your ongoing business environment. Softek LDMF host-based software can migrate datasets from virtually any storage vendor array to any storage vendor array in mainframe environments as well as move easily between

2 different disk capacities. As a result, your organization can benefit from increased flexibility and optimized application performance and storage utilization while maintaining application availability. Balancing storage loads to help improve application performance Typically, IT staff members monitor storage usage and activity on a daily basis to maintain the highest level of application performance possible. And, storage administrators may have to move datasets between storage units, volumes or both, based on the input/output (I/O) activity, which can require downtime for the application. But with Softek LDMF software, you can migrate specific datasets from poor-performing volumes to higher-performing volumes, helping increase application performance levels almost immediately. Softek LDMF Now you have the flexibility to improve application performance by relocating datasets to higherperforming volumes. software can also improve application performance by relocating selected datasets when needed, moving datasets in real time without disrupting application accessiblity. Helping you migrate to high-performance, large-capacity disks Making decisions about which application datasets to move to specific locations on new storage can present major challenges to most IT organizations. Extensive planning and preparation are required. 2

3 Data conversion onto large volumes can take weeks to complete. And if significant application downtime is required, it can affect your ability to meet business service level agreements (SLAs). With Softek LDMF software, datasets can be quickly migrated from smallcapacity volumes and merged onto larger-capacity volumes while applications remain online and available. You can minimize migration preparation time by choosing from an extensive dataset selection for application datasets. And you can automatically update the volume metadata and catalog information, allowing you to accomplish tasks without scheduling significant downtime. Although other nondisruptive migration solutions exist in the marketplace today, these solutions migrate data at a volume level, which doesn t address the business need to move individual datasets. However, Softek LDMF software is able to solve these storage deployment issues. Replacing time-consuming manual methods with a sophisticated online alternative Doing something manually can often mean engaging in a project that takes extra work and time. This can be especially true for performing manual dataset-level migrations. Extensive manual work and planning can go into creating control cards for all datasets and into ensuring that enough space exists for migration. Plus, manual migration operations can be risky, with the potential to overlook a critical dataset or run out of space on the target volumes, resulting in data corruption or data loss. The good news is that Softek LDMF software offers one of the only online alternatives to manual dataset-level migrations, which can help you to: Eliminate time spent on manually creating control cards Reduce the risk of running out of disk space by validating that there is enough space on the target volumes prior to starting the migration Support mounting service-level pressures from the business by performing migrations while datasets remain open. Enabling more rapid utilization of storage Who needs unplanned downtime? With the ability to migrate datasets online, you no longer need to wait for a downtime window to move datasets. Your storage administrators and technical 3

4 staff now have the flexibility to move datasets at will when and where they need to without affecting application availability. And you can enable more rapid adoption of higher-capacity volumes and utilization of new technologies. Plus, with Softek LDMF software, you can realize a greater return on your storage investment by: Reducing costs with fewer storage subsystems to manage Enabling more rapid capacity optimization Moving datasets based on storage tiers to help repurpose existing storage Aligning dataset placement with internal and external compliance regulations. Reclaim three UCBs by combining multiple small volumes into one larger volume for continued application growth. Establishing more effective UCB management through volume consolidation Your mainframe UCB limits can constrain data growth. However, by moving and consolidating datasets from multiple smaller-volume subsystems to largervolume subsystems, hundreds of UCBs can be reclaimed and used to support new business expansion initiatives. 4

Storage hardware Supports 3380 and 3390 volumes formatted with z/os technology supporting count key data/extended (CKD/E) format. 5

6 And with Softek LDMF software, you can increase system growth by: Freeing up UCBs to allow continued growth of business-critical information Using nondisruptive migration capabilities to sustain data integrity and business service levels Reducing the number of logical volumes on a device by consolidating several small-capacity volumes onto fewer large-capacity volumes. Grouping datasets for easier management of large migrations Separate migration groups can be created in the Softek LDMF software. Each migration group can include a list of datasets that were created using extended dataset selection. After the migration group is created, specific datasets can be excluded. Target volumes are then identified as the destination for the dataset-level migration. Target volumes can be specifically named or defined by Storage Management Subsystem (SMS) group. Once activated, Softek LDMF software will copy designated datasets to the target volume while the application is up and running. Your IT staff does not have to schedule downtime for applications, helping to ensure ongoing operations in support of your business continuance objectives. More importantly, the entire data migration can be performed through the mainframe and not through any storage subsystem.
