System Storage. TM Benefits of Premium Features Storage Partitioning • • Allows the sharing of capacity across multiple servers User can define which server(s) can have access to specific data Flash. Copy • • • Supports utilization of separate data copies, for a variety of uses such as hot backups or application testing No affect to production data – remains online accessible Instantaneous Volume. Copy • • • Allows for redistribution of data from older, slower disk drives to faster and/or higher capacity drives Optimizes application performance and/or capacity Complete separate physical copy of data that can be used for analysis or testing with no effect on production data IBM Internal and IBM Business Partner Use Only © 2007 IBM Corporation

System Storage. TM What is Storage Partitioning? • A logical unit consisting of one or more volumes that can be accessed by a single host or shared among hosts • Host A Host B Host Group C One or more volumes are mapped to an individual host or host group • This volume-to-LUN mapping defines what host or host group will have access to the volume • Partition access is maintained at the controller level Logical partition A Logical partition B Logical partition C LUN 0 LUN 1 LUN 2 unmapped volumes IBM Internal and IBM Business Partner Use Only © 2007 IBM Corporation

System Storage. TM What is Flash. Copy? • A point-in-time (Pi. T) image of a logical drive • Logical equivalent of a physical copy • Features: C’ Instantaneous copy • Requires less disk space than a full copy • Map-able to any host • Can be read from, or written to • • Primary uses: ABC Base Logical Drive Flash. Copy Logical Drive C’ Flash. Copy Repository Pi. T backup image • File restoration • Data mining / analysis • Physical Logical A point-in-time image can be created in seconds IBM Internal and IBM Business Partner Use Only © 2007 IBM Corporation

System Storage. TM What is Volume. Copy? • Complete (byte-by-byte) Pi. T replication of one logical drive (source) to another (target) within a storage system Production Server Analysis Server Target logical drive also referred to as a clone • Eliminates I/O contention on the primary logical drive • • Primary uses: Full Pi. T data set available for analysis, mining, testing, backup • Migrating data between storage tiers • Source logical drive Pi.
