  1. EMC Centera Technical Review

  2. Storage Costs Information’s Business Value EMC Centera for Information Governance and Compliance • “Purpose-built”, active archiving platform • >5,500 customers and >370 PB shipped • >11,000 systems shipped • Assured content authenticity and online access • Highly available, high performance • Five-9s: No single point of failure • Integrity protection at all levels • Continuous disk scrubbing • Multiple file protection • Self-healing: files, data bases, disks

  3. Content Authenticity Easy to manage Low TCO EMC Centera—An Archive Solution • Content authenticity ensures: • Internal storage—content/data faults detected and automatically healed • Network transmissions—transmission errors detected and transfer repeated • Easy to manage • Administrators can manage up to 50 times greater quantity of content • Works with any application or any platform • Centralize archive silos from multiple data repositories • Enable thousands of users to share single multi-application repository • Helps meet governance and compliance requirements

  4. Four node 16-node cube 2 cubes/ cabinet Multiple cubes form a single cluster ARCHITECTURE Redundant Array of Independent Nodes (RAIN) Centera node • Storage nodes/access nodes • 2.8 GHz P4 processor • 1024 MB DDR RAM • Four - 1 TB or 2 TB SATA-II • Two 1 Gbit network-interfaces • One 1 Gbit to outside LAN (copper/optical) • A node can be in one of 3 modes • Access node • Storage node • Access/storage node Centera network • Dual 24-port cube switches • Gigabit Ethernet connections to facilitate additional cubes • Redundant connection to each node Extreme scalability • Massive parallel processing • Add storage: processing power, memory, bandwidth

  5. Centera Stores and Retrieves Objects ARCHITECTURE Objects have metadata date name <My_Archiving_Application> <MagazineCover name=“Time” photo=“Annan” date=“Sep 4, 2000”/> <Reviewer name=“Jones, Ted”/> </ My_Archiving_Application> photo • Applications create metadata associated with one or more objects • Objects are stored independent of volume/directory information

  6. Centera Requires No Backups ARCHITECTURE Centera • Dramatically reduces opportunities for errors to affect data access or authenticity • If an error occurs, it can be discovered and healed How? • Fixed content prevents data overwrites by applications • Content authenticity, independent copies, self-monitoring, self-healing • Detection and healing of bad disk blocks • Content regeneration from loss of entire disk • Detection and healing of FS errors • Content regeneration from total loss of FS Limited configuration • Human error cannot affect the archive filesystems or disks • No active management of these resources

  7. Centera Failure and Self-Healing Model ARCHITECTURE Failure Detection Remedy Regenerate node Regenerate disk • Regenerate database • Regenerate blob • Regenerate filesystem Presence of node Presence of disk • Database health • Read/write errors Disk scrubbing Blobs Metadata Blocks • Connectivity • Software heartbeats Node failure Full disk failure • Database failure • Block failure Filesystem failure • Network failure • Software failure Restore data • Alert EMC

  8. ARCHITECTURE Single Instance Storage Duplicate information stored only once. song G Regardless of how many copies of an object are sent to the Centera, the object is only stored a single time.

  14. Centera: Low TCO MANAGEMENT No complex storage area networking management No file systemmanagement No LUN/RAID Group carving or allocation • Investment protection—multi-generation hardware support • One addressable pool—ingestion machine for content • Constant validation of content objects and structures

  18. Centera Console EMC Centera Console is a web-based user interface which enables administrators to monitor their EMC Centera environment. It can be used to: Monitor EMC Centera alerts View capacity and performance data in real time or over a defined period View replication topologies and status Check the progress of self-healing tasks Export data to comma-separated-value (CSV) and HTML file formats MANAGEMENT

  20. SCALABILITY Centera Virtual Archive—Vision Information Policy Mgmt across a large virtual archive. Serving up authenticated & secure information wherever needed. Allowing Content to migrate freely in and out of the archive.

  21. SCALABILITY Centera Virtual Archive: Breakthrough Technology • Ultimate scale, without disruption • Seamlessly aggregate multiple clusters • Virtualize new and existing clusters • Increase single view capacity (PBs) • Improved manageability at scale • Applications interact with a single virtual environment • Retrieve objects stored on any cluster • Better resource utilization of available capacity • Eliminate geographic boundaries • Overcome the limitations of space and distance Virtual Archive

  22. Virtual Archive Federation Gen2/Gen3 CentraStar 4 Gen4 (LP) CentraStar 4 GenX CentraStarX ? Centera Virtual Archive software Centera Virtual Archive 1.0 SCALABILITY Technology agnostic Advancing the abstraction of archive implementation • Life time of a digital archive far exceeds the life of a computer technology; hardware, software or architecture • Centera/VE is software, hardware and architecture agnostic • Older and newer technology live concurrently in a Federation • Seamless CAS functionality for different technologies in one digital archive • Support for different Software versions

  23. Centera Virtual Archive software Centera Virtual Archive 1.0 SCALABILITY Adding Virtual Archive to an existing cluster • Install the Centera cluster • Install the Virtual Archive software • For replication, install the target site in the similar way and enable replication • The application is communicating directly with the Virtual Archive software installed on the new cluster • Virtual Archive will redirect any traffic to the existing cluster as needed

  24. Pool 1 Pool 1 Pool 1 Pool 2 Pool 2 Pool 3 Pool 3 Pool 3 AVAILABILITY Distributed Content for Business Continuity and Disaster Recovery • Pools and replication • Replicate selected Virtual Pools • Replicate all Virtual Pools Source Target

  25. LAN LAN Application server Application server AVAILABILITY Centera Replication • Asynchronous over IP • Unlimited distance • Unidirectional, bidirectional, chain or star • Ability to “pause” replication • No host or human resources • People are not duplicating optical platters or worm tapes • The same content address exists in both clusters Router Router A study by the University of Texas reveals that only 2% of companies suffering from a catastrophic data loss survive after one year. The ability to resume normal operations and productivity rapidly is a critical business requirement.

  26. COMPLIANCE Centera and Compliance Centera Basic • Provides all functionality without enforcement of retention periods Centera Governance Edition • Process-centric on the lifecycle of electronic records and enabling policies and technologies • Restricts the retention and deletion of data but does not conform to SEC regulations • Suitable for most regulations Centera Compliance Edition Plus (CE+) • Designed for the strictest of regulation requirements, specifically SEC 17a-4 • Restricts the retention and deletion of data according to SEC regulations

  27. Set litigation hold Remove litigation hold CentraStar: Guaranteed Object Lifetimes COMPLIANCE CentraStar provides both fixed and variable retention periods, along with an on-demand legal-hold facility fixed retention deleteallowed C0 event not specified fixed retention event-based retention deleteallowed C1 fixed retention event not specified event-based retention deleteallowed C2 event not specified fixed retention event-based retention deleteallowed C3 Time C-Clip Created Event

  28.
