  1. Storage Service Providers? Jim Gray Microsoft Research Panel Talk at VLDB 2001

  2. WebDAVhttp://www.ics.uci.edu/pub/ietf/webdav/http://www.webdav.org/WebDAVhttp://www.ics.uci.edu/pub/ietf/webdav/http://www.webdav.org/ • Web Data Authoring and Versioning • File Sharing via the Web • DASL: DAV Searching and Locating • Basis for Web file sharing apps • SharePoint™ and other tools • WebDAV redirector in WindowsXP • WebDAV support in Oracle IFS • Products & Free-Ware in MacOS, Linux,… • But, unit isFile(& directory) not Object • Naming • Versioning • Security

  3. x Business Models: x: xSP • ISP: Thin client-fat server • Presentation at client (browser) • application at server • ASP: fat-client fat server • Presentation, context management at client • Business logic and data at server • SSP: fat client thin server • Presentation, business logic, and DBMS at client • File or Disk Blocks at server

  4. iSCSI SSP? • The SAN story on the Internet? • Client does file management • File does disk space management • Client does security • Client does….. • SAN: • not a good idea in a LAN • Terrible security, naming, performance in a WAN • Not likely

  5. File SSP • NAS Story on the Internet • What many are doing. • Scale8, Others • Disaster backup • Archival storage • A good business for WORN data Write-Once Read Never

  6. WORN Business PlanInternet NAS: 9,000% profit margins • Rich customers buy storage for 1,000$/GB from 3-letter companies. • Poor / shrewd companies buy storage for 10$/GB from no-name companies. • Same disks in both boxes!!! • Can receive data over Internet for 1$/GB. • Profit = 1,000$-11$ = 989$. a chance 8,990%profit

  7. Management Cost: 8$/MB/Y ???(== 8 B$ / PB / Y) • Lets see: • 1 Exabyte of disk shipped last year == 1012 MB • So storage management cost (for last years’ disks):8 Trillion $/y == 10 % of world GNP? • Probably not. • My guess <80B$ (including DBMS) =< 8 cents/MB/Y. (total software + labor + DBMS tax).< 3x disk vendor revenue. • 8$/MB/y seems to be a rumor started by the 1$/MB storage vendors.

  8. Free Advice x = W • Become a WSP (web service provider)if you are service oriented. • Not 9,000% profit, but… • It’s the right place to put the architectural line. • Includes being a WebDAV SP.
