2 Market Growth Trending Disk Space

3 A Growing Issue in the Environment Unstructured content growing faster than traditional information or structured content –Database or transactional data 75% to 90% of data is unstructured –Requires unique capabilities for archive management Exabytes

4 Changes in Legal Discovery Traditional archiving technologies cannot retrieve relevant content in a timely manner –How long would it take to retrieve 10,000 or 100, 000 items? Traditional storage technologies do not have the functionality required for archiving and discovery FRCP –Rule 26f: Within 100 days of a suit being filed parties must meet and disclose any issues relating to disclosure or discovery of ESI

5 Litigation E-Discovery Timelines Pre Amendment E-Discovery Rules Suit Filed Motions Negotiations Discovery/Productions Trial Suit Filed Motions Negotiations Discovery/ Productions Trial Summary Judgments Settlements December 1st, Amendment E-Discovery Rules “Meet and Confer” Days and weeks versus months and quarters to discover

6 Discovery Defensibility Can you found all electronic documents? Do you know everywhere to look? Are there unknown copies that will emerge later? Does the other side have something we don’t? Will we find out the answers to any of these during the trial? Will we face sanctions for not finding it?

7 Different Schools of Thought “Delete every after 30 days” –Users aren’t supposed to keep PST files but do “If you want to keep something after 30 days then print it and save it” –How do you ever find it? “Sure we archive, we save our backup tapes” –Backups are not an archive “ We maintain strict limits on file server capacity. Anything over the limit is deleted” “All employees who leave have their data deleted” “We don’t know what we have so we don’t delete anything” –Sometimes this happens by itself or by a court order See HDS Whitepapers by Contoural

8 Six Critical Steps to Managing ESI* 1.Create an ESI Survey Data Map System description, scope, data flow, organization, data formats 2.Update records retention and deletion policy and then execute it Is it realistic? Is it flexible? 3.Effective litigation hold and discovery process 4.Delete documents the business does not need 5.Designate and prepare a Rule 30 (b)(6) witness Someone that understands the data Typically from IT or the Business Unit 6.Audit your process and refresh your policies on a periodic basis See HDS Whitepapers by Contoural

9 Content Awareness What Do We Have? –Some applications have built-in classification and search capability ECM Archiving Databases –Many do not systems without archiving File servers How Do We Find It? –How many places do we have to go to search across the enterprise? –What if a common storage system could have full text search of everything?

10 Home Grown Application Medical Imaging Supports multiple applications and content types Embedded full-text indexing and search High-performance, scalable and secure storage File System Document management Archive Software Discovery Module Hitachi Content Archive Platform: How it Works

11 Key Concept: Archive Object Management Fixed content files contain reference content that must be preserved or retained Metadata contains descriptive attributes about the file Policy information is special metadata that governs file retention, disposition and protection, plus guarantees file authenticity over time Users and applications write and read files; internally, they are managed as objects

12 Navigators provide drill down by key terms, file type, and retention View additional file system and archive metadata Search Result Set Support for: 370 File Formats 77 Languages Full-text, metadata and system data indexing Set/Release Retention Hold Export Results Discovery Optional Advanced Search Capability

13 NFSWebDAVCIFS/SMB HTTP or HTTPS  Performance close to HTTP gateway  Supports RFC 2518 compliant clients  “MountPoint” just part of URL  Compatibility interface, primarily for UNIX  Mount by cluster reference  High protocol overhead  POSIX  Compatibility interface, primarily for Windows  Map network drive to cluster file system path (data or meta data)  Fastest gateway  Many good client libraries  GET, PUT, EXISTS, DELETE operations  Can specify metadata in URL Access Protocols SMTP  Fastest gateway using batch mode  Supports standard SMTP mail clients  Ingestion only – no read NDMP  Standard backup/restore gateway for the archive.  Data and metadata packaged into transportable objects

14 Document management Instant messaging Data creation applications server Database sever HCAP Accessibility Standard and open gateways make access easy. Content searching makes access even more immediate. Preservation and RAS with HA SAN Heterogeneous cluster storing fixed content is self managing, scalable, and permanently available. Open Standards NFS, CIFS, HTTP, WebDAV, SMTP, NDMP Custom applications HCAP

15 Key Features: Preserve and Protect P Protection  Self-configuring and self-healing with automated policy enforcement, failover and ongoing integrity checks  Ensures specified number of replica copies are maintained to tolerate simultaneous points of failure by maintaining 1 to 4 internal copies depending on value of data  Policies enforce document retention, authentication and file replication combine to secure valuable digital assets  Keep management “soft costs” to a minimum Encryption of Data at Rest (optional service at installation)  Protects content from being recovered from stolen media using patented “Secret Sharing” technology  Transparently encrypts all content, metadata and search index X X X X XX X X X X Shredding  Ensures no trace of file is recoverable from disk after deletion  Complies with DOD specs Replication  Object based: Bi-directional  Files, metadata and policies  Options for compression and encryption in flight built into HCAP 21 May May WORM, Immutability and Retention Write once, read many file system where content is stored in an immutable format with the ability to set file-level retention

16 Duplicate Elimination  Find and inspect duplicates  Remove duplicates, but maintain integrity Key Features: Optimize File Compression  Reduces the physical size of the data stored in Hitachi Content Archive Platform  Enables greater storage efficiencies, scalability and enhances TCO Open Interoperability Supports UNIX and Microsoft file systems, can store standard file formats such as XML and HTML, and can leverage other Hitachi SAN storage platforms Single Archive Name Space All objects are stored in a single, archive-wide global name space, a well understood paradigm Open and easy to navigate with standard tools and applications Simple Monitoring and Management Can be configured and monitored through a Web-based interface and through SNMP Scalability Provide enterprise scalability and upgrade paths to create a long term archive
