Architectures:From Video Storage to Campus Rich Media Services Alan McCord and Dan Hague University of Michigan SURA/ViDe Conference March 26, 2003 SURA/ViDe
Agenda • 0-10 minutes • Introductions, Al setting the stage for Dan • 11-30 minutes • Dan describing his IP SANS solution • 31-50 minutes • Al weaving the IP SANS solution into a model architecture for rich media on campus • 51-60 minutes • q/a and discussion SURA/ViDe
Introduction • Individual campus video projects can easily require many Gigabytes of storage for even a short ten-minute asset. Once stored, those assets need to be cataloged, streamed and otherwise re-purposed. SURA/ViDe
Remember This Scene? Digital video of patient interview Tape of 1975 orchestra concert Brent Scowcroft dialog 1962 Robert Frost poetry reading Championship field hockey game Yesterdays’ CHEM101 lecture SURA/ViDe
The Campus Challenge • We need to acquire, index, access, use, and archive “perishable IP” for • Course delivery (on-campus and DL) • Archives and collections • Research projects • External communications (Web, Broadcast, and print) SURA/ViDe
Why DAMS Is Important • Our networks can support digital video payload • Students use P2P to manage media assets • BUT • Rich media still absent from most instruction • Lack of large-scale rich media services • Faculty and librarians lack experience / tools for managing rich media individually or institutionally • Lack of tools to manage IP rights • Lack of rich media workflow tools SURA/ViDe
How Do We Do This? • A campus-wide collaborative approach • Metadata standards • Ingestion, cataloging, and retrieval tools • Lots of bandwidth • Lots of storage • Disk attached storage (DAS) inexpensive but lacks speed and scalability • Traditional storage area networks (SAN) are difficult to manage in highly decentralized organizations • IP-based iSCSI storage may serve campus-wide needs for fast, inexpensive, scalable video storage SURA/ViDe
eStorage - UM Mass Storage Large Scale storage as applied to the Unified Messaging project and the Video Storage, Logging and Retrieval solution SURA/ViDe
Unified Messaging • High Availability • Redundant Architecture • Scalability Port • Load Balancing Between Ports • Load Balancing Between Switches SURA/ViDe
Video Storage, Logging, Retrieval • “Huge” Storage Volumes (68 GigaByte up to 1 TeraByte) • Performance & High Throughput • IP Network Centric • Standards Based • Utilize UM Purchasing to drive down costs SURA/ViDe
High Availability • If one switch fails the hosts are served by the redundant switch. SURA/ViDe
Redundancy • Redundant Power Supplies • Redundant Cooling Fans SURA/ViDe
Scalability Port • To cascade between switches there is a scalability port that allows the creation of a director class switch. SURA/ViDe
Load Balancing Between Ports • Four (4) FC storage ports are available per switch. SURA/ViDe
Load Balancing Between Switches • The load can be spread over multiple switch ports • Each switch has 3 GigE ports • Each switch has 4 FC ports or 6 SCSI ports SURA/ViDe
4 each JBOD chassis 28 each 73 GigaByte FC drives (68Gig after formatting) 2 each controllers / switches development 2 each controllers / switches production Huge Storage Volumes SURA/ViDe
Performance and High Throughput • 7000 packets per second using 1500 Byte packets ~ 84 M throughput • 11,000 packets per second in other tests • MPEG-2 4:2:0 remove video encoding from the Media Union to Arbor Lakes • Clustering of MS Exchange Servers to support Unified Messaging SURA/ViDe
IP Network Centric • Dedicated Fibre Channel SAN islands are becoming a thing of the past • Leverage large qualified support staff that support existing campus IP network • Storage is available on demand to IP connected devices from any high speed IP faceplate SURA/ViDe
Standards Based • iSCSI draft standard has been ratified by the ITEF and new beta products are showing up every month • Microsoft will include the iSCSI driver in Windows2003 (previously Windows.net) • Cisco and IBM will continue to deliver iSCSI drivers until the OS versions are stable SURA/ViDe
Additional Storage via UM Purchasing • Traditional vendors require storage upgrades to be purchased from the switch manufacturer • 2 more Terabytes are needed and the acquisition will go through UM Purchasing • More vendors are entering this market every quarter driving down the cost SURA/ViDe

Storage Summary • We are applying iSCSI storage today for: • Unified Messaging • Video on Demand • We are looking at applying iSCSI for: • Archiving 70,000 .wav files for the hospital • Increasing the storage on existing NAS servers internally within our department • Driving down the cost of file storage to allow the DAMS solution to reach more students and faculty SURA/ViDe
What Are We Up To? • Potential DAMS “early wins” • Course management systems • Digital libraries • Personal > unit > institutional repositories • Evaluating three COTS DAMS product suites • DAMS not a core competency • Leverage developer investment • Focus on open standards and tools SURA/ViDe
Market Segments • Content repositories (brand management) • Workflow management (marketing production) • Content and version control (Web production) • Digital media ingesting and logging • DAM infrastructure tool suites • Digital rights management • Encryption and content distribution systems • Systems integration services • Hosting services SURA/ViDe
What Are The Components? • Integrated repository for content & metadata • Infrastructure to manage digital media assets • Ingesting and format conversion * • Metadata tagging and cataloging * • Searching and retrieval • Packaging and delivery to creative and production environments * • Managing flow and control of assets * • Managing IP rights and rules * SURA/ViDe
Digital Asset Management Content Management and Production Media Assets Database Audiences Web - Internet Web - Intranet Internal UM Information External Publications Controlled Access Search Assets Preview and Edit Production Publish/Distribution • Search on: • Text content • Keywords • Speech • Sound/music patterns • Image descriptions • “More like this” search on: • Image content • Audio content • Video content • Parallel preview (thumbnail) and Rich-data view: • File/Asset size • Compression type • Quality • Language • Translation • Preview edit • Compressed format • Rich format • Rights & royalties • Searchable • Display • Reporting • Translate • HTML • XML • Text • Video formats • Audio formats • Publish • To multiple media formats • Distribution via • Network • User-defined industry standard output devices (DAT, BETA-SP, ZIP, CD-RW, etc) • Edit tools • Application tools and integration of industry standard tools for applications where requested by customer (e.g., MS Word, Avid Media Composer, Adobe PhotoShop, etc.) • Content • Size • Cropping • Output Format/File type What DAMS “Is” To Us What DAMS “Is” SURA/ViDe
