1 A guide for customers IBM hardware-assisted data migration services Helping simplify data migration to IBM TotalStorage systems with minimal complexity and disruption IBM TotalStorage solutions with their robust function and significant priceperformance benefits can help businesses simplify their infrastructure and move to on demand computing. IBM TotalStorage solutions are designed to provide the flexibility to respond to customer needs, simplify storage management and provide automation that can reduce staffing needs. Whether moving from another vendor s storage to a highly scalable IBM TotalStorage solution or helping clients upgrade, move, consolidate or replace existing IBM storage, data migration can be a challenge. The need for safe, secure and nondisruptive data transfer is a growing concern for most IT departments today. Many IT groups postpone justifiable upgrades because they are concerned that the upgrade process itself might disrupt ongoing business operations. IBM TotalStorage hardware-assisted data migration services, part of the family of IBM migration offerings, can help simplify data migration in open systems and mainframe environments while addressing issues of complexity, disruption, system performance, host availability and data integrity. It combines a migration appliance tool, utilizing patent-pending IBM technology, with the experience of IBM services professionals. Together they can help speed data migration to IBM storage systems, including the new IBM TotalStorage DS8000 and DS6000 series. IBM services professionals can help manage your data migration by: Jointly building a plan for data migration activities Installing and configuring a data migration hardware appliance tool and infrastructure-enabling components, when needed Performing a migration and moving data from source disks to new target disks Reviewing volume migration records, validating results and verifying connectivity from the new disks to host systems Removing the data migration hardware appliance tool Why data migration services? Data migration is becoming an increasingly important issue when switching from an alternate vendor s storage platform, or upgrading, moving, consolidating and/or replacing existing storage. IT environments with a mixture of application servers and 24x7 service levels can make scheduling and executing data migration a complex, expensive and time-consuming task.

2 I ve been in this business for twenty-five years, and the support we get from IBM has been pivotal to the success we re achieving in meeting our customers demands. Many companies do not have an IT staff with the skills, experience and the bandwidth to make a smooth data migration transition. They want to be assured that the migration they need will be accomplished quickly and safely, without the risk of data corruption or loss and with minimal outage. Data migration for open systems The IBM data migration hardware appliance for open systems is a half-height, rack-mounted device with fibre channel (FC) switches, patch panels, an Ethernet hub, a management console, eight data migration engines and dual power distribution all packaged in a rugged box on wheels. There is also a lite, smaller version of the appliance based on the same technology. These tools are designed to enable local and remote migration among multivendor Steve White, Vice President of Information Systems Services, ISO storage and hosts in FC and small computer system interface (SCSI) environments, providing transparent logical unit number (LUN) level copy of data and nondata using a private storage area network (SAN), switches and routers. Data is migrated by using a private SAN positioned between the customer s SAN and storage, while mapping source LUNs to target LUNs. For online migrations, the migration appliance routes all online I/O from host to source LUNs and target LUNs and copies data from source LUN to target LUN. It masks target LUNs from the host during migration and offers support for fully redundant configurations. Host agents need not be installed and removed from production servers. Generally no more intrusive than a fibre channel switch, the data migration appliance is designed for easy installation and IBM services professionals can easily connect it to a host system s storage interfaces. Normally, no changes to customer host systems or SAN fabric are required. The datamoving elements of the data migration hardware appliance report the source storage system s vital product data. Because data does not flow through the management interface, no external access exists to the proprietary data being migrated, helping to maintain data integrity. The data migration hardware appliance is designed to be tuned for maximum host system performance to help reduce the performance impact of a data migration process on end users running their applications. The appliance is also designed to take advantage of multipath redundancy between itself, hosts and storage systems. If a problem occurs, an appliance can be removed from the environment and a system can be returned to its original configuration.

3 Recent IBM TotalStorage data migration engagements Industry Challenge Solution Benefit Travel The client outgrew its three-vendor storage environment and needed the capability to support corporate growth while reducing storage maintenance costs. IBM upgraded the client s IT environment and consolidated storage on its IBM TotalStorage Enterprise Storage Server Model 800. The simplified storage environment saves operating costs and system maintenance costs after three years, while doubling server capacity to accommodate significant data growth. Manufacturing The client needed to consolidate part of its storage infrastructure to improve efficiency, performance and return on its IT investment. IBM configured several IBM TotalStorage storage systems and fibre switches, and migrated data to them quickly. The client was able to leverage the advanced function technology and cost benefits of IBM TotalStorage. IBM provided rapid data migration services to help avoid additional lease expenses while enabling data integrity. Government The client was looking for a solution to increase data sharing across locations and a storage infrastructure to support it. Two IBM TotalStorage Enterprise Storage Servers (ESS) became the sole disk solution, with backups being performed over the SAN for all attached servers. Data was quickly migrated from the existing EMC disk to an IBM disk. Estimated cost savings have been projected, as well as improved performance, reliability, data management and scalability for future growth. Healthcare The client wanted to replace EMC disks with IBM TotalStorage ESS disks, leverage its advanced technology features and rapidly migrate the date within a four hour outage window with the help of a specific IBM Business Partner. IBM, working with the IBM Business Partner, successfully implemented a new solution and moved 150 mod 3 volumes in less than two hours. The client has benefited from increased system throughput and storage growth for data and information. Data migration for mainframe systems The IBM data migration hardware appliance for mainframe systems is based on an IBM S/390 Multiprise 3000 enterprise server with the IBM z/os operating system, and is equipped with up to 22 ESCON adapters for data migration use. This appliance is mounted in a standard 30-inch rack on wheels, uses standard 110V AC power and requires no communication connections. It uses a specialized preloaded software utility called FDRPAS from Innovation Data Processing that is designed to move data with little or no degradation to host processing cycles for IBM mainframe systems. This IBM service is designed to allow the migration of MVS, OS/390 and z/os volumes, including SYSRES volumes, other system volumes, open catalog volumes, application data volumes, IBM CICS volumes, data volumes, IBM DB2 volumes, time-sharing

4 option (TSO) volumes, systemmanaged storage (SMS) volumes and work volumes. The migration appliance also supports parallel access volumes (PAV) and consistency groups. Special considerations and planning are required to process volumes containing active local page data sets. The data migration appliance is designed for easy installation. IBM services professionals can simply connect it to a host system s storage interfaces. If only IBM FICON adapters or ports are available on the target storage, the IBM team can provide temporary ESCON adapters for use during the migration. Because the data migration appliance can be configured before it is placed in a data path, the time to physically attach and remove it can be as little as fifteen minutes. Because data does not flow through the management interface, no external access exists to the proprietary data being migrated, helping to maintain data integrity. The speed of data migration depends on a number of factors: the number of channels provided for the source and target storage systems, whether data goes through a director and the level of volume activity when volumes are moved. The data migration appliance is also designed so that if a problem occurs, it can be removed from the environment and the system can be returned to its original configuration. It is also designed to help reduce or eliminate the impact of a power failure or initial program load (IPL) during migration from source volumes. The volumes being copied would need to be restarted but all volumes previously swapped before the event would be on the new disk subsystem and no action is necessary. Advantages of using IBM data migration services Using this hardware-assisted approach and its prescribed tools, IBM can deliver migration services for both open systems and mainframe data by transferring data between source and target volumes with host servers online or offline. These services can help speed data migration, avoid disruption of production servers and minimize the potential impact on application performance. Migrations normally occur with minimum dependency on IT staffs. Because the CPU cycles or MIPs used to perform migrations are on the data migration hardware appliance tool and not on customer systems, users can continue to run their applications as before. Another advantage of the IBM hardware-assisted migration approach is that once an online migration begins, its speed can be decreased or increased to meet specific processing needs. For example, if applications running during a migration require additional resources, IBM can slow down the migration process. IBM can also help when specific volumes of data need to be migrated by a certain deadline or within a specific time frame. In addition, data can be moved, application by application, unlike most competing solutions that usually migrate from one subsystem to another. Above all, IBM hardware-assisted data migration services can help businesses gain a competitive advantage and reap the benefits of IBM storage technologies by enabling essential storage upgrades without the complexities and risks of traditional data migration approaches. Note: Some systems such as VM/ESA and VSE/ESA can be migrated in offline mode only. For details about this mode and other migration issues, please contact your IBM sales representative or IBM Business Partner.
