22. #2 – Get yourself ready !! Server Architecture
● Think very carefully about the feature:server/cluster ratio
─ 12 features (inc. new Forum feature): 12 WAS servers (JVMs) is usually too many
– wasted memory, hard to maintain, difficult to tie up errors across servers
─ 12 features : 1 WAS server is often too few
– log files get very very busy, administration not granular enough, takes too long
to start/stop
● 3-6 servers works best
● This is my favoured model:
─ pcserver
– Profiles, Communities and Forum
─ infraserver
– Homepage, News, Search and Mobile
─ appsserver
– Activities, Blogs and Dogear (Bookmarks)
─ fwserver
– Files and Wikis

23. #2 – Get yourself ready !! Server Architecture
● This architecture keeps co-dependent features together, scale/tune based on
load/users/volumes, allow fast start/stop if customizing
● An example four-server single-system
architecture

24. #2 – Get yourself ready !! Focus on Profiles
● Spend at least three times as long planning Profiles population, integration and
customisation as planning the Connection environment itself
● Can be a massive area for scope-creep - define, document and stick to plan!
● Involve all the relevant stake-holders at an early stage
─ Particularly Human Resources, Communications/Marketing, Reception/Telephony
groups etc.
● Phase your Profiles rollout - often feedback from pilot groups can be opposite to
expectations
● Profiles population usually the most important factor influencing Lotus
Connections adoption
● Pre-populate Profiles photos, no matter what it takes!
● Consider using TDI to populate LDAP then populate Profiles
● Plan for business card use elsewhere, and for Lotus Sametime presence
awareness
