Represents a Swedish Premium Business Partner:
●
Presenting the Case Study:
─
IBM Lotus iNotes deployment at Stockholm County Council

3
What is the Stockholm County Council?
●
Stockholm County Council is English for Stockholm Läns Landstings
─
Know in Sweden for its abbreviation SLL
●
SLL's mandate is to ensure that its 2 million residents have access to health
care and public transport as well as preventing health problems.
●
SLL is one of Sweden's largest employer in Sweden
─
─
45 000 employees
96% work in health care

Why iNotes?
●
SLL started in 2002
─
─
●
Each organization within SLL had their own mail solution or multiple solutions
Even though mail solutions were present, there was a lot of drawbacks:
– Basically every available product on the market was in use due to the large
amount of different solutions
– About 30% of all SLL employees didn't have access to mail or where using
group accounts
– There where no or very little security in these solutions
– Availability was delivered on a “best effort” basis
– And there were no or very little protection against virus and spam
Mail was an area with potential for improvements
─
─
SLL IT Council Committee initiated a project to establish and deploy a centralized
mail solution based on IBM Lotus Domino
It was voluntary for the organizations within SLL to join the central mail solution
– The central solution had to show compelling business values in order to make
the organizations move
© 2011 IBM Corporation
5
Why iNotes? (continued)
●
The new central mail environment showed these business values:
─
─
─
─
─
●
Lower TCO
Higher availability
More performance
Added functionality
Easier administration
Why was iNotes chosen in preference of Notes?
─
The organizations within SLL determined that iNotes was:
– Cheaper and easier to roll out
– Cheaper and easier to maintain
– Required less user training
– All in all a lower TCO
© 2011 IBM Corporation
6
How did SLL build their iNotes solution?
●
Combining high availability, high performance and low costs isn't easy
─
●
SLL defined two mindsets to help them keep costs down:
– “Automation instead of administration”
– “Centralized operations, decentralized administration”
SLL first focused on the foundation, the back-end architecture
© 2011 IBM Corporation
7
Back-end architecture
●
The back-end architecture was placed in two geographically separated sites
and placed within the core network of SLLnet
●
SLLnet is SLL's WAN
─
─
Highly available
High performing

Clustering
●
All server roles that needed to provide its services in a high availability
configuration were clustered, mostly in a very common mirrored cluster
configuration
●
However for the Mail Servers SLL chose a different clustering method, a
method that could be explained as a “multiple non-mirrored cluster”. It's actually
a single Domino cluster with eight server members. But the mailboxes aren't
mirrored between the servers, instead they are randomly and asymmetrically
distributed between all eight servers.

Clustering (continued)

the opposite site

Automation & archiving
●
To help keep costs down SLL focused on automation
─
─
●
A product called User Management Tool (from Infoware Solutions) together with
custom administrative applications created an automated user management process
Many additional custom administrative and products were user for additional
automation processes and application used for self administration/service desks.
Server-based archiving
─
─
A product called Mailpak Archiving Tool (from Infoware Solutions) was deployed to
help keep storage costs down
– Low performing (cheap) storage was used for the online archive
The mail servers got added performance due to less data to manage
– High performing storage was used for the mail servers
© 2011 IBM Corporation
12
SLL's iNotes solution
●
Solid back-end sorted out, only thing needed was a front-end
─
─
─
●
SLL wanted transparent failover and load balancing of iNotes
Many different products were looked at and discarded
WebSphere Edge Components were chosen
Front-end
─
─
Products:
– WebSphere Edge Dispatcher (load balancers)
– WebSphere Edge Caching Proxy
– WebSphere Edge Content Based Router
– WebSphere Application Server (LDAP authentication)
Customization:
– Login application
– Web service to CLDBDIR.nsf to get user's mail servers for load balancing
– Proxy plugin for the web service look up
© 2011 IBM Corporation
13
SLL's iNotes solution (continued)
●
Every HTTP request is load balanced
─
Failover is completely transparent to users
●
Since forms85.nsf is located on all eight mail servers, all mail servers are
involved in presenting iNotes data.
●
Since users have two mailboxes, both mail servers holding their mailbox is
involved in load balancing and failover of the content in the mailbox
●
Proxies do URL-masking, user always sees mail.sll.se
●
Firewall between the front-end and back-end ensures that only the proxies can
communicate with mail servers over HTTP
─
─
●
SLL is terminated by the proxies which makes the mail servers gain performance
Only one SSL certificate is needed which help keep cost down
Proxies caches requests for added performance

Lessons learned & best practices
1 Sort out the back-end first
2 You need a front-end
3 Maintenance work during office hours is possible with a front-end
4 With a front-end you only have one place for SSO integration
5 Load balancing utilizes HW better, make sure you don't overscale
6 Notes and iNotes users can co-exist
7 iNotes demands less user training than Notes
●
(depending on your users skills)
8 Automation is a primary key to cut TCO

What's next for SLL?
●
8.5.2 upgrade
─
─
●
Virtualization
─
●
SLL is currently in the middle of an upgrade to 8.5.2 that is planned to be completed
by Q1 2011
With this upgrade they are looking into implementing DAOS to further reduce the
storage costs
Even more cost reducing actions are made with further virtualization of their
infrastructure
Sametime 8.5
─
─
Sametime is being deployed to provide online meetings, chat and awareness.
And of course Sametime will be integrated with iNotes

IBM Lotus iNotes Redirect
●
Overview
─
─
─
Domino application based on the IWAREDIR.NTF template
Allows Lotus iNotes users to access their mail file and mail server using only the
name of the iNotes Redirect server
Uses Domino authentication methods to redirect a user's browser to their mail file
based on their username and password
●
Create Lotus iNotes Redirect application using IWAREDIR.NTF template
●
Configure Redirect application
─
This can be done through the Notes client.

─
How to look up mail file and mail server
Fixed
– Force redirection to the specified url, eg user comes from domino.acme.com
and setting is set to mail.acme.com, the URL will become mail.acme.com
Dynamic
– The url is built from the incoming URL request. eg. mail1.acme.com
MailServer
– Rewrites the URL to be the home mail server.

(continued)
●
Reverse Proxy field can be used to add name of reverse proxy server that will
be used as “junction” name in the redirection URL
─
NOTE: This does NOT provide reverse proxy functionality; you still need a reverse
proxy server
© 2011 IBM Corporation
27
IBM Lotus iNotes Redirect Server Settings

●
In general, when working with reverse proxies, use the Fixed mode
─
Leave the server name field blank

28
IBM Lotus iNotes Redirect Server Settings
(continued)
●
To assist load balancers working in a clustered environment, a form called
“ServersLookup” (new to 8.5.2) has been made available and will reside in the
Redirect database
─
─
When requested by the load balancer
The ServersLookup form will return one of two HTTP response headers in the
format X-Domino-xxxxx, each containing a comma separated list of servers.
– X-Domino-ReplicaServers is returned when the service finds the relevant path
within its own cluster
– X-Domino-ClusterServers is returned only when the mail servers are part of a
different cluster.

30
IBM Lotus iNotes Redirect Server Settings
(continued)
●
Coming in 8.5.3
─
Omit http protocol from redirect URL
– Default is No, which means the redirect URL will include the http(s) protocol
– This is useful in scenarios where external users will be using https as provided
by a reverse proxy and internal users will be using http against the back-end
Domino server
© 2011 IBM Corporation
31
IBM Lotus iNotes Redirect Server Settings
(continued)
●
Coming in 8.5.3
─
Use home mail server for Domino Directory lookups
– Default is No, which means lookups will be done against current server hosting
the Redirect server
– This is useful when supporting multiple Domino domains, each with its own
Directory, and using one Redirect server. Previously, lookups would only be
done against current server which could result in improperly constructed
redirect URLs. Allowing lookups against the user's home mail server will ensure
the redirect URL is properly built.
– Note that this will need the Redirect server to be added to the Trusted Servers
field on the remote server

IBM Lotus iNotes Redirect UI Settings
●
UI Setup
─
─
─
Personal Options allow users to specify which iNotes area they want to start in, eg.

IBM Lotus Sametime Integration with reverse
proxies
●
Requirements when deploying with a Reverse Proxy server
─
─
─
●
Edit stlinks.js (located on both Sametime and Domino iNotes servers)
– var ll_RProxyName=”https://ReverseProxyHost.acme.com”;
– var ll_AffinityID=”st8”;
– Note: The stlinks directory which contains stlinks.js may get overwritten during a Domino
server update. It's recommended to backup stlinks.js and hostInfo.js, which may have
been customized.
Edit stconfig.nsf --> Meeting Services (located on the Sametime server)
– Reverse Proxy Enabled: True
– Reverse Proxy Alias: st8
Reverse Proxy example settings
– Proxy /st8/communityCBR/*
http://sts.acme.com:8082/communityCBR/*
– Proxy /st8/*
http://sts.acme.com/*
– ReversePass http://sts.acme.com/* https://ReverseProxyhost.acme.com/*

Requirements for WebSphere Caching Proxy Server
─
Enable PUT and DELETE method directives as required by the Sametime Proxy server
─
Add rewrite and mapping rules for iNotes and Sametime with junction points in order for
requests to be sent to the proper server
─
Lastly, in order to keep access secure, it's recommended to configure SSL between the client
browser and the reverse proxy server.

IBM Lotus Sametime Proxy 8.5 configuration
(continued)
●
Domino Server Configuration
─
The Sametime Proxy server used by iNotes users is defined on the Domino server by setting a
notes.ini var. There are two possible server settings, iNotes_WA_SametimeProxyServer and
iNotes_WA_SametimeProxyServerSSL. We recommend using both settings as follows:
– For intranet/internal users, set iNotes_WA_SametimeProxyServer to the URL of the actual
Sametime Proxy server.
●
iNotes_WA_SametimeProxyServer=http://stproxyServer.company.com:9080
– In the case where intranet/internal users are required to make a secure connection
●
iNotes_WA_SametimeProxyServer=https://stproxyServer.company.com:9443
– For internet users, set iNotes_WA_SametimeProxyServerSSL to the URL of the reverse
proxy
●
iNotes_WA_SametimeProxyServerSSL=https://revproxy.company.com
