Agenda Motivation/Need Importance of collaboration servers Leading Products
IBM/Lotus Discovery Server Microsoft SharePoint Portal Server 2003
Comparison & Contrast Deployment Considerations Conclusions
Motivation/Need Formalize knowledge markets Discover patterns of knowledge Identify covert experts Capture knowledge formally
Best practices Technical reports Status of documents/projects
Collaborative Servers Bring people together
KRD type information Act as electronic librarians
Search for expertise, papers, etc. Manage projects Provide “total view” of company
Avoid blindness Selective blindness
IndustriesBusiness practices and processes that focus on information access, knowledge sharing, business application availability, and collaboration between remote users are the best candidates to be implemented within a portal framework across business domains that include financial services, manufacturing, and telecommunications companies.
- Cognizant Technology Solutions (2002)
Enterprise Portal Market
Leading Products IBM/Lotus Discovery Server
1550 worldwide installations (2002)
Microsoft SharePoint Portal Server 2003
IBM/Lotus Discovery Server Search Expertise Location Capture “relevant experiences”
Extracts, analyzes, & categorizes “Reveals” relationships Automatically generates and maintains K-maps Generates & maintains user profiles – “uncovers”

Microsoft SharePoint Portal Server “Connects users, teams, and knowledge” Enterprise solution Single log-on (point of access) Customization & personalization of portal
Organizational role Team membership Interest Security
Locate documents, processes, and best practices Integrates into existing applications
Searching Files Web servers Microsoft Exchange Server folders Lotus Notes
Automatic/push notification on additions and changes
Document Management Versioning Approval workflow Check-in and check-out Status tracking/profiling
Customized Information
Searching
Document/Information Sharing
SharePoint PerformanceNumber of users Recommended topology
< 1,000Single server with Microsoft SQL Server 2000 Desktop Engine (MSDE)
< 10,000 Single server with SQL Server 2000
< 25,000 *
Small farm: Front-end Web server (1),
SQL (1+, optionally clustered)
< 100,000
Medium farm: Front-end Web server or search (2),
index or job (1), SQL (1+, optionally clustered)
> 100,000Large farm: Front-end Web server (2+), search (2+), index (1+), SQL (1+, optionally clustered)
Single ServerServer type RAM Hard disk CPU
Web, index, search, and database
1 gigabyte (GB) 100 GB Dual 2.8 GHz Pentium 4
A system built with the hardware described in the preceding table should have the following performance characteristics:
Process 15 requests per second (Peak common action) (including 2 searches per second) with MSDE
Note MSDE has a database size limit of 2 GB and a limit of 5 concurrent jobs.
Process 32 requests per second (including 4 searches per second) with SQL Server
Index 5 documents per second
Store up to 100,000 documents (using SQL Server)
Index up to 1 million documents (using SQL Server)
Host up to 10,000 team and personal sites
Host up to 5 portal sites (using shared services)
Large Server FarmServer type RAM Hard disk Number of computers
Web servers 2 GB 100 GB 2
Search servers 2 GB 200 GB 2
Database server 2 GB 200 GB 1
Index management server
2 GB 100 GB 1
A system built with the hardware described in the preceding table should have the following performance characteristics:
Process 100 requests per second (Peak common action) including 15 searches per second
Index 10 documents per second (up to 625-1105 of various types if scaled)
Store up to 1 million documents
Index up to 5 million documents
Host 50,000+ SharePoint sites and personal sites
Comparison/Contrast Both offer
Searching Document sharing/managing Contact information
Discovery Server Discovers knowledge, relationships K-maps
SharePoint More customized view (portal: calendar, news, etc.)
Deployment Considerations Consider existing IT infrastructure
Lotus Notes → Discovery Server Microsoft Office/Exchange → SharePoint
Integration to other systems possible, but potentially problematic Upgrades could break links
Leverage existing interfaces K-map rules/relations may require
“oversight”
Conclusions Online collaborative tools vital
Sharing documents Version control, profiling
Personnel directory/searching Provides views of company Access to experts
Tool selection dependant upon current technologies in place Document/user size may be a consideration
