Setup Considerations
Installation & Setup

Install The Bits – Follow the Basic
Steps
1. Plan and Prepare; Verify hardware and software requirements
2. Install the required software updates on all farm servers
3. Install the SharePoint 2013 prerequisites on servers in the application and Web tiers
4. Install SharePoint 2013 on the application server and the Web servers
5. Create and configure the SharePoint farm
6. Provision service applications as needed
7. Complete post-deployment tasks as required

Prepare the Servers
SharePoint Preparation Tool
◦ Checks for presence of prerequisites
◦ Installs and configures required packages
◦ Requires internet connection to pull down missing prerequisites
◦ Can be run w/o internet connection to check for missing prerequisites

Public Updates and Hotfix Packages
◦ Update WFE & App servers as appropriate
◦ Ensure SQL Updates installed
◦ Ensure all SharePoint servers are at the same patch level

Request Management (RM)
The purpose of the Request Management feature is to give
SharePoint knowledge of and more control over incoming
requests
Having knowledge over the nature of incoming requests – for
example, the user agent, requested URL, or source IP – allows
SharePoint to customize the response to each request
RM is applied per web app, just like throttling is done in
SharePoint 2010

RM – Goals
RM can route to WFEs with better health, keeping low-health WFEs alive
RM can identify harmful requests and deny them immediately
RM can prioritize requests by throttling lower-priority ones (bots) to serve
higher-priority ones (end-users)
RM can send all requests of specific type, like search for example, to specific
machines
Isolated traffic can help troubleshoot errors on one machine
RM can send heavy requests to more powerful WFEs

RM Components
Request Manager (RM)
Request Throttling and Routing
Throttle if appropriate, or select which
WFE’s the request may be sent to

Request Prioritization
Filter WFEs to only ones healthy
enough for the request

Request Load Balancing
Select a single WFE to route to, based
on weighting schemes like health

New Replacement for Web Analytics Service

The Analytics Platform replaces the Web Analytics service
application
Some of the reasons for that included:
◦There was no concept of item-to-item recommendations based on user
behavior, i.e. people who viewed this also viewed foo
◦Couldn’t promote search results based on an item’s popularity (as
determined by # of times an item was viewed)
◦It required a very powerful SQL box and significant storage and IO
◦Lists don’t have explicit view counts
◦The architecture could have problems scaling to large numbers

How the New Platform Improves on
Analytics
The new Analytics Processing engine aims to solve these issues:
◦Find relevant information (improve search relevance) – based on views, click thru, etc.
◦See what others are looking at (“hot” indicators and usage numbers – i.e. what’s popular
based on # of views as well as # of unique users to view)
◦Understand how much content is being used (i.e. viewed) and how it compares to other
documents
◦See discussion thread usage and find the hot topics
◦Use this popularity info to populate views through the Content by Search (CBS) WebPart
◦The model is extensible for 3rd parties to build into the platform

Processing and Storing Analytics Data
•Data goes through an analysis and reporting process that is
contained within the search service application
•Things like views and counts are combined with click-thru and other
search metrics and pushed into the reporting database
•Some data like view counts are also pushed into the index so it can
be included in search results, sorted on (i.e. what’s most viewed),
etc.
•An analytics processing job examines data for clicks, links, tags, etc.,
as well as the usage data to create the data points used for
reporting

New Cache Service
•There is a new distributed cache service in SharePoint 2013, based on
Windows Server AppFabric Distributed Caching
•It is used in features like authentication token caching and My Site social
feeds
•SharePoint 2013 uses caching features that cloud-based cache (Windows
Azure Cache) does not support at this time, so only local cache hosts can be
used; may change in the future
•SharePoint ONLY supports the version of caching that it ships – you cannot
independently upgrade it.

New Cache Service (cont.)
•A new Windows service – the AppFabric Caching Service – is
installed on each server in the farm when SharePoint is installed
•It is managed via the Services on Server page in central admin as
the Distributed Cache service
•The config DB keeps track of
• which machines in the farm
• are running the cache service

Cache Setup
•The farm account is used as service account for Cache Service
•Like user profile service in SharePoint 2010, during setup the
service account should have elevated privileges (i.e. local
admin)
•After setup is complete you should lower the privileges for the
account

Cache Architecture
For caching in farm, scale points have not been
determined yet
◦How many servers are needed, what resources should be built
out (CPU, memory, etc.)

Themes
•The themes engine has been completely reworked
•Everything is now based on HTML instead of proprietary format – including support
for HTML5
• PowerPoint is no longer used to create custom themes
•You get much richer themes and common building blocks for customizing them
• A background image, palette and fonts with live preview
•You can “try it out” to see how it looks

This is what the new theme gallery looks like, along with a sample of an HTML 5 based theme:

Sharing – Problems
Sharing in SharePoint 2013 is designed to solve these common problems from
previous versions of SharePoint:
Granting access to a site can be a bit convoluted
◦Users don’t understand what permission level to grant to other users
◦Users generally don't know who all has permissions on a site
◦Users can’t see the invitations that have been sent out to external users.
◦Users don’t understand what rights they are giving people when they add
them to a SharePoint group

Sharing - Problems
Access requests on SharePoint are very limited
◦You can only request access if you have no access at all
◦No obvious ways to ask for additional access
◦You can’t share with others if you don’t have Grant Permissions right, which only
Owners have
◦Users have no way of seeing the status of their requests
◦Sharing is typically done for the whole site, when usually the only thing people
want to share is a web, list or library
◦Site owners don’t have a place to see all pending requests and to manage them
Users can’t see the level of access they have

Sharing - Solutions
Sharing in SharePoint 2013 is designed to address these limitations with the
Sharing feature:
◦ A Sharing dialog for adding users, distribution groups, and security groups
◦ An email invitation with a message that can be customized when it’s sent out
◦ A “request on behalf of” feature, where if you don’t have rights to add someone to the site,
you can send a request on someone else’s behalf.
◦ A requests management page where admins can view and respond to all requests
◦ A Personal Permissions page where users can request more permissions than they currently
have
◦ A conversation component to requests, so admins and users can have a dialog about the
request

Sharing Process
Users can share a site from the Site Actions menu
Users request access via the access denied page, like before
If a user has the Grant Permissions right, they can share themselves
Otherwise the requests must be handled by an admin
NOTE: You MUST have configured the outgoing SMTP server for a
web application or the “Share this site” menu option will not appear
for anyone but site collection admins

Sharing Process
•The admin sees the list of all the pending requests in the Access
Requests and Invitations page
• A link also shows up on Site Permissions when request are pending
•You can accept or decline a request, or add comments to
request additional details
•Users can view all of their own pending requests from the Site
Permissions page
•They can also see and respond to admin comments
