IBM Storage Sales Strengths of EMC Centera § Allows Single Instance Storage – One and the same object is stored only once – In-band data deduplication § Scalable based on RAIN Architecture – Storage is added via storage nodes (disk only) – Performance scales with access nodes (Ethernet connectivity) – Supports Active-Active Mirroring relation between nodes § Includes Outboard Search capabilities in Centera – Allows to search for Content § Established and recognized Product in the market – Many customer references available, many ISV support EMC Centera API § CAS architecture is a marketing advantage – Content Address can be used to validate content authenticy – Clever idea, but not required by regulations *Based on preliminary findings of internal IBM projections. © 2007 IBM Corporation

IBM Storage Sales Weakness of EMC Centera § Does not offer Tiered Storage or alterative storage technologies – Higher TCO, especially for longer term archiving – Less flexibility for migration to other storage technologies § Data protection only through additional disk – Content Mirroring is not synchronous – No backup of data to less expensive storage media § Sticky Technology – Replacement of MD-5 hash requires application to read all data § Known Performance Issues – According to non-disclosed sources and ISVs – Partially caused by RAIN Architecture (CAS and Centera Network) § No data encryption included *Based on preliminary findings of internal IBM projections. © 2007 IBM Corporation

IBM Storage Sales Key Strengths for IBM DR 550 § DR 550 allows for lower Total Cost of Ownership for long retention times – DR 550 supports true tiered storage (disk, optical, tape) – With removable media storage DR 550 is more energy-efficient – With Centera data is kept on disk for long archival period, less energy efficient § DR 550 includes Data Migration Functions – Centera is disk centric, migration just from disk to disk § DR 550 is not a sticky Technology – DR 550 leverages industry-leading technology such as TSM – Centeras’ CAS implementation is sticky § DR 550 provides flexible options for Data Protection – DR 550 provides synchronous mirroring or backup to tape – Centera requires disk and even more disk § DR 550 has leading Archival – Retrieval Performance – Get real numbers from EMC Centera and compare it to DR 550 § DR 550 includes Data Encryption Techniques – On disk via API encryption, On tape via Tape encryption © 2007 IBM Corporation

IBM Storage Sales Data Migration § Who knows which storage technology is “most appropriate” in the future? – Holographic Storage and solid state disk is just “around the corner” – Storing data on disk for long periods might become really expensive § Long term archiving requires to migrate data to other storage devices and – technologies in the future – As well as migration of client, DMS and other infrastructure § With EMC Centera customers are bound on disk – Migration to other technologies becomes more complicated and might not be transparent to the application § DR 550 has Data migration capabilities built-in – New storage technologies are supported by SSAM – Data Migration is transparent to application © 2007 IBM Corporation

IBM Storage Sales DR 550 Competitive Attack Points IBM DR 550 EMC Centera Customer Business Value Tiered storage with attached WORM or non-WORM tape helps provide lower total cost of ownership Centera data is disk only, which is more expensive due to initial purchase cost, and power, cooling and service costs over long archiving periods Lower TCO with DR 550 over long archiving periods by off-loading “aged” data to lower storage tiers (e. g. tape or optical) and Implements ILM practices Integrated data migration capabilities for long term archiving: DR 550 supports many storage technologies (disk, tape, optical) and data migration functions. As data “outlives the media”, DR 550 provides transparent migration capabilities to new storage technologies. EMC Centera is disk centric, with no media migration path to other storage technologies. Improved operational efficiency for long term archiving and commitment to open architecture Addressing the risk of technology obsolescence High performance archive and retrieve enabling data EMC will not publish performance data. Vendors DR 550 offers improved return on overall IT investment rates of up to 60 MB/sec and more than 2000 report significant performance deficiency of EMC through improved overall system throughput, scalability objects/second. Scalable performance through multi Centera compared to DR 550. and quick access to archived data -object transaction enabled by TSM API. Disaster protection options: DR 550 supports synchronous and asynchronous replication as well as asynchronous replication (backup) and offline vaulting to many external devices. Asynchronous replication only, does not provide integrated capability for backup and offline vaulting. Synchronous mirroring offers higher data protection with better recovery point objective and lowers risk of data loss as result of a disaster. DR 550 maintains data integrity via hardware RAID and embedded Cyclic Redundancy Checks (CRC) EMC Centera Content Addressable Storage IBM DR 550 built-in data integrity capabilities help to (CAS) technology is not future proof. The content assure compliance and enable transparent upgrades of address will become vulnerable, and then the data integrity check methods. application will need to read and rewrite all objects in order to provide a new, more secure content address. The DR 550 has flexible data encryption with the option for transparent key management done by the DR 550 or by the application. Data encryption is not included. Flexible encryption options protect data using tiered storage, and additionally prevent sensitive data disclosure on removable media that could be misplaced. Built-in and cost-free file archiving solution via SSAM Archive Client No built-in file archiving solution. Offers cost efficient file archiving solution. DR 550 scales in three dimensions: storage, performance and price (economies of scale) Only scales in one dimension: storage. It does not scale performance or price. Supports growth, provides investment protection, enables an open architecture for archiving, and lowers TCO. Backup to tape offers lower TCO than backup to disk over long archiving periods. Another option for data encryption is on the tape storage media with key management by DR 550 or another key manager. © 2007 IBM Corporation

IBM Storage Sales EMC Centera on z. OS § Here are some limitation I see with this solution – Not a one-hand solution: 3490 or 3995 emulator from third (either bustech - 3490 or interkom - 3995). – No retention management with this solution, because the leading application on z. OS such as CM or CMo. D does not send the retention time for an object. – Leading application is device dependent, thus future migrations to other device have to be performed through the leading application. – No hierarchical storage management. Thus the data will always be on disk. This causes much higher TCO. – z. OS is IBM-World, thus the integration between hardware and software is much better with an IBM DR 550. – 3490 and 3995 architecture is fairly old. 3490 or 3995 Emulator z.

IBM Storage Sales EMC Centera and TSM § TSM and SSAM support EMC Centera as storage device § There are many limitation making it impossible to migrated data from or to Centera: – No Migration. – No Reclamation. – No Move data into or out of a Centera storage pool. – No Moving node data into or out of a Centera storage pool. – No Storage pool backup of Centera storage pools. – No Restore volume of Centera storage pool volumes. – No Exporting data to a Centera device class or importing data from a Centera device class – No Using a Centera device class for creating backup sets; however, files stored in Centera storage pools can be sent to backup sets. – No Defining Centera volumes. – No Using a Centera device class to back up a database. – No Using a Centera device class for database loading or unloading. – No Using a Centera device class as the target of volume history, device configuration, trace logs, error logs, or query output files. © 2007 IBM Corporation
