  1. Content Addressed Storage (CAS) Module 3.5

  2. Content Addressed Storage (CAS) Upon completion of this module, you will be able to: • Describe the features and benefits of a CAS based storage strategy. • List the physical and logical elements of CAS. • Describe the storage and retrieval process for CAS data objects. • Describe the best suited operational environments for CAS solutions. Content Addressed Storage (CAS)

  3. Lesson: CAS Description and Benefits Upon completion of this lesson, you be able to: • Define CAS. • Describe the key attributes of CAS. • List the features and benefits of CAS. Content Addressed Storage (CAS)

  4. What is Content Addressed Storage (CAS)? • Object-oriented, location-independent approach to data storage. • Repository for the “Objects”. • Access mechanism to interface with repository. • Globally unique identifiers provide access to objects. • Extensible metadata that enables automated data management practices and applications. Content Addressed Storage (CAS)

  5. What Is Fixed Content? Generate New Revenues Improve Service Levels Leverage Historical Value Digital Assets Retained For Active Reference And Value Electronic Documents • Contracts, claims, etc. • E-mail and attachments • Financial spread sheets • CAD/CAM designs • Presentations Digital Records • Documents • Checks, securities trades • Historical preservation • Photographs • Personal / professional • Geophysical • Seismic, astronomic,geographic Rich Media • Medical • X-rays, MRIs, CTI • Video • News / media, movies • Security serveillance • Audio • Voicemail • Radio Content Addressed Storage (CAS)

  6. Challenges of Storing Fixed Content • A significant amount of newly created information falls into the category of fixed content. • Fixed content is growing at more than 90% annually. • Often, long-term preservation is required (years-decades). • Simultaneous multi-user online access is preferable to offline, or near-line storage. • New requirements and service level agreements have created the need for faster access to records. • Need for location independent data, enabling technology refresh and migration. • New regulations require retention and data protection. • Traditional storage methods are inadequate. Content Addressed Storage (CAS)

  7. Shortcomings of Traditional Archiving Solutions • Tape is slow, and standards are always changing. • Optical is expensive, and requires vast amounts of media in order to store data of any size. • Both solutions require 3rd party media management. • Many times companies retire tape products without warning. • Many times recovering files from tape and optical is time consuming. • Data on tape and optical is subject to media degradation. Content Addressed Storage (CAS)

  8. Benefits of CAS • Immutability and authentication • Location independence • Single instance storage • Faster record retrieval • Record-level retention, protection, and disposition • Technology independence • Online (like Disk) • Optimized TCO • Scalability Content Addressed Storage (CAS)

  9. Lesson: Summary Key points covered in this lesson: • CAS Definition • CAS Description • Benefits Content Addressed Storage (CAS)

  10. Lesson: Elements of CAS Upon completion of this lesson, you will be able to: • Describe the Physical Elements of CAS. • Describe the Logical Elements of CAS. Content Addressed Storage (CAS)

  11. API Physical Elements of CAS • Storage devices (CAS Based) • Servers (to which storage devices get connected) • Client Client Server CAS-basedStorage Content Addressed Storage (CAS)
