SharePoint Server 2013Problem

Saving a Site Template with activated Publishing Feature is not possible in SharePoint 2013 (menu link missing).

When using the direct browser link (which worked perfect in SharePoint 2010) http://YourSharePointSite/_layouts/15/savetmpl.aspx you get the error The "Save site as template" action is not supported on this site.

Save site as template error

 

Solution 

Modify the SaveSiteAsTemplateEnabled property in your SPWeb object via PowerShell.

# Store your Site in a variable:
$SiteToModify = Get-SPWeb http://YourSharePointSite

# Display the current value of the property:
$SiteToModify.AllProperties["SaveSiteAsTemplateEnabled"]

# Set the property to true:
$SiteToModify.AllProperties["SaveSiteAsTemplateEnabled"] = "true"
$SiteToModify.Update()

 

Screenshot PowerShell

 

When now trying the savetmpl.aspx link again, you can save your template:
http://YourSharePointSite/_layouts/15/savetmpl.aspx

Save as Site Template working

When setting up Exchange Server or any other Enterprise application that provides IIS services (i.e. SharePoint), it might be a requirement to change the default folder path für IIS log files to a different location than the default location (C:\inetpb\logs). Even though todays physical or virtual system drives are in the 100GB range, it might be a design requirement to have the folder path placed on a different volume.

Especially when you have to configure more than one server, you prefer to have configurations implemented by script.

The script Set-Webserver.ps1 provides in its current release the configuration of:

  • IIS log folder path
  • IIS log period
  • Local time filename and rollover configuration

Additional configurations, like logExtFileFlags, logFormat, truncateSize, can be implemented, if required.

The script runs on Windows Server 2008 R2, Windows Server 2012 and Windows Server 2012 R2.

How many characters should have a password in order to be considered safe?

Office 365 limits the password length for users not synchronized with on-premise Active Directories to 16 characters. Can this considered to be safe? 

Office 365 administrators need to be aware of the fact that the new Administrative Tools do not show a warning when a new user is created. When pasting an initial password into the textbox, no warning is displayed. But the password itself has already shortened to 16 characters automatically.

Screenshot Initial Office 365 Password

The summary page shows the shortened password after the new user has been created. The administrator needs to pay proper attention to the status summary to notice the shortened password.

When logging in for the first time the user experience is different. The user is notified that the password cannot exceed 16 characters.

Screenshot Change password after first login

Microsoft should rethink the limitation of 16 characters to enhance the security level for user login. 

 

Update
In May 2019 Microsoft introduced a change to Azure AD to support password with 256 characters in length.

Today's virtualization options provide a wide variety to even virtualize business-critical enterprise applications. Distributed enterprise applications can easily be virtualized but require proper planning. Otherwise, you will end up with virtualized SharePoint Server Farm that does not scale well and perform badly.

This article will provide information on how to virtualize your production environment properly and will not necessarily cover development environments, as those tend to run in over-committed scenarios anyway.

The following table provides a simple overview of the SharePoint farm terminology:

Farm Size Farm Description
Small Farm A simple architecture consisting of two web servers and a single SQL Server.
One of the two web servers hosts the Central Administration while the other serves content to end-users.
A small farm is supposed to serve about 10.000 users.
Medium Farm A more complex architecture consisting of at least two Web Servers, at least two application servers and more than one SQL Server.
When you start with a small farm, you can easily scale out to a medium farm.
A medium is supposed to serve about 10.000 users per web server. 
Large Farm After scaling out your medium farm you will end up with a large farm.
In a large farm, you group your servers according to their role (web server, application server, SQL Server). If required you scale-out per group.

 

Never ever start a SharePoint production deployment with a single multi-role SharePoint Server.

The following figure illustrates the architecture of a SharePoint Server 2013 environment example.

SharePoint 2013 Example Architecture

Capacity and Performance: These two key aspects are the most important aspects when you plan your SharePoint virtualization infrastructure. You need to plan for enough disk capacity to host all of the content databases and data that is cached to disk by the web server and application server roles. Your overall capacity should be planned at least for a three year period. The requirements for CPU and memory sizing of the virtual hosts depends on your server requirements. A virtual host should always be equipped to the physical maximum. If you leave CPU sockets empty, there is no guarantee that you will get the CPU for that socket in the future. The memory banks should be filled in the proper ratio per CPU as well. Otherwise, you will not be able to fully benefit from the virtualization of your servers.

 

Virtualizing the Load Balancer

Mostly all of the major vendors of hardware load balancers offer virtualized load balancers as well. As long as the virtual load balancer is not running on an over-committed host, and sufficient performance is provided, there is no legitimate reason to not virtualize a load balancer. 

Especially when you maintain a large virtualization platform you are heavily interested to not add additional hardware complexity to your network infrastructure by adding hardware load balancers. Any additional layer of complexity adds an additional layer for support as well.

Some of the major vendors are (purely alphabetical):

 

Virtualizing the Web Server role

Web servers are easy to scale because web servers generally provide much better performance by adding additional CPUs and memory resources. This is the reason why the webserver role within a SharePoint deployment is the easiest to scale out. Because it is so easy to just add additional resources it is not automatically the right approach. Performance-wise you will reach a point where adding an additional web server makes more sense. This decision if you extend the resources of an existing server or add a new virtual machine depends on the overall virtualization infrastructure and the available hardware resources.

Another important topic to think about is the migration of virtual machines between hosts and the high-availability functionality of your virtualization platform. A virtual machine can be moved between virtual hosts more quickly when the virtual machine is not over-sized. The larger the assigned resources are, the more time it takes to migrate a virtual machine. You need to keep this in mind not only for migrations due to maintenance reasons or virtual hosts fail-overs. The same is true when you utilize the automatic load balancing of virtual machines.

NUMA nodes are an additional important topic. Microsoft provides dedicated information to NUMA nodes SharePoint here. Even though the article is focusing on Hyper-V, the general NUMA node requirements are valid for other hyper-visor platforms as well. As per Microsoft performance can decrease by up to 8% when a virtual machine needs to access remote memory from another NUMA node.

The proper sizing of memory resources ensures that your web servers perform as expected. You need to ensure that the webserver does not require to swap memory and make heavy use of the page file. Any use of the page file results in unnecessary disk I/O. And depending on the disk subsystem the required I/O reduces the performance dramatically. Even though the operating system supports the hot-adding of virtual memory, not all application functions make use of added virtual memory. Some components recognized available memory during the start-up of the operating system and do not adjust themselves during run time (e.g. Distributed Cache).

Your SharePoint server running the webserver role should be configured with at least:

  • 2 CPU
  • 8 GB Memory
  • Single Volume hosting the operating system and the SharePoint Server application files

 

Virtualizing the Application Server role

The CPU demand of SharePoint application servers depends heavily on the applications that are running on those servers. Some applications might be more CPU resource-intensive (e.g. Search), others might be more memory intensive. To find the proper sizing for your specific requirements you need to monitor the system resources not only on a general level (e.g. System CPU usage, system memory consumption) but on a more granular level (per service, per application pool, per worker process). 

Your SharePoint server running the application server role should be configured with at least:

  • 2 CPU (4 CPU, if running multiple applications on a single server)
  • 8 GB Memory (16 GB, if running multiple applications on a single server)
  • Single Volume hosting the operating system and the SharePoint Server application files

 

Virtualizing the Database Server role

The virtualization of SQL Server is a separate topic that will be covered in more detail in a separate blog article. But it would be unfair to leave this section more or less empty.

First of all, it should be said that even SQL Server can be virtualized. If virtualizing SQL Server is an option for your IT infrastructure depends on the SQL Server and data warehouse design of your company. Some companies prefer to host SQL databases in central SQL Servers serving all data applications within the company. Other companies prefer to host SQL databases on different SQL servers and group those by SQL Server SLA and/or by the type of data stored in databases.

In this example, we assume that there are three SQL Server 2012 dedicated to SharePoint in use. The following table gives a brief overview of the recommended memory sizing for SQL Server virtual machines:

Combined size of Content Databases Recommended RAM
Small deployments 8 GB
Medium deployments 16 GB
Large deployments (< 2TB) 32 GB
Very large deployments (2 TB - 5 TB) 64 GB
Extremely large deployments (> 5 TB) 64 GB and more

 

SQL Server 2012 provides a new functionality called AlwaysOn Availability Groups (AAG). The AAG provides a much better experience and performance when it comes to database fail-overs. But at the same time, you need to plan resource requirements in a different way than you were used to with classic Windows Clustering capabilities. An AAG does have a primary replica of a database and many secondary (passive) replicas of the same database.

AAGs can be operated in two different availability modes:

  1. Asynchronous-commit
    The primary replica commits transactions without waiting for confirmation by the secondary replicas.
    This mode is similar to high-performance mode with database mirroring.
  2. Synchronous-commit
    The primary replica waits for the acknowledgment of all secondary replicas.
    This mode is similar to high-safety mode with database mirroring.

 In our example we have two different AlwaysOn Availability Groups configured:

  1. AAG1: Synchronous-commit
    This AAG supports the databases for Central Administration and the SharePoint configuration databases.
    These databases do not rely so much on database performance, but we want to make sure that the data is properly protected.
  2. AAG2: Asynchronous-commit
    This AAG supports all SharePoint content databases.
    We want to achieve the best performance for the content databases. 

Summary

The SharePoint 2013 farm example ends up in the following virtual host demands:

SharePoint Server Role CPU (Cores) Memory Disk
Web Server Role 3 x 2 3 x 8 GB 3 x 100 GB (OS, SharePoint)
Application Server Role 3 x 2 3 x 8 GB 3 x 100 GB (OS, SharePoint)
Database Server Role 3 x 4 3 x 16 GB

3 x 100 GB (OS, SQL Server)
3 x 1 TB (Databases)

Total 24 96 GB 1,9 TB

 

To be able to have a single virtual host in maintenance, but still have redundancy we need to plan for at least three virtual hosts. But even in this case one of the two can fail. Therefore you need to protect yourself from a failure while having on a virtual host in maintenance. The disk subsystem is connected to each host by fiber channel or iSCSI on a dedicated 10GB network.
