AlwaysOn advantages Latest and greatest SQL HA solution More reliable
Although database mirroring is still available in its original feature set, it is now considered a deprecated feature and will be removed in a future release of SQL Server More reliable AlwaysOn (one primary, can have up to three corresponding secondary replicas) Mirroring (one primary, one mirror) Multi-database failovers Useful in applications with several databases Databases can be added to an Availability Group that can be failed over between replicas All databases in Availability Group are failed over at the same time © 2012 Microsoft Corporation.

MICROSOFT MAKES NO WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, AS TO THE INFORMATION IN THIS PRESENTATION.

AlwaysOn Availability Groups
Provides high availability by maximizing availability of databases for an enterprise An Availability Group is a set of databases that are failed over together at the same time Supports one primary replica and up to two secondary replicas in synchronous-commit mode Availability Group listener responds/redirects incoming client requests to replicas Each Availability Group replica has local SQL instance and local copy of databases

AlwaysOn Failover Cluster Instance (FCI)
Provides high availability through redundancy at the server-instance level One SQL instance is installed across all failover clustering nodes Single copy of databases are located on shared disk storage which is failed over between nodes

SQL AlwaysOn Planning

9/10/2018 Planning for AlwaysOn New install scenario Install new backend using SQL Enterprise 2012 or SQL Enterprise 2014 Add new Skype for Business Server pool with AlwaysOn back-end to topology Install Skype for Business Server and add databases to Availability Group Upgrade scenario Upgrade an existing Lync Server 2013 pool to Skype for Business Server Upgrade back-end server to SQL Enterprise 2012 or SQL Enterprise 2014 Enable SQL AlwaysOn for Skype for Business Server databases © 2012 Microsoft Corporation.

2013 patching and reliability challenges
Microsoft Skype for Business 9/10/2018 2013 patching and reliability challenges Complex patching process with many steps; deviations from the process might result in downtime for users Ready state-to-start patching not always reliable Could run into unable to start front-end servers after patching Some users are signed in with limited functionality and sign-in performance issues Problems are hard to troubleshoot and solve— particularly for larger pools Understand upgrade domain/other fabric concepts Icon: Bjorn Andersson, Noun Project © 2012 Microsoft Corporation.

Server management Patching

Lync 2013 Skype for Business

Skype for Business Server patching
Simplified workflow leverages Windows Fabric v2 APIs 4 steps: Invoke-CsComputerFailOver to failover (stop) a front end; take the FE out of rotation, move the replicas out Perform patching/upgrade Invoke-CsComputerFailBack to failback (start) a front end; bring FE into active state, move replicas in Do this for all front ends in the pool

Invoke-CsComputerFailOver
Microsoft Skype for Business 9/10/2018 Invoke-CsComputerFailOver Checks for availability of sufficient number of servers Waits for replica stability across the pool Confirm all replicas exists before taking server down Initiate deactivation of the node; wait for success/failure from windows fabric Stops services after successfully deactivating the node © 2012 Microsoft Corporation.

Invoke-CsComputerFailBack
Start services if not already started Activate node—windows fabric will now consider this server for replica placement

9/10/2018 How is this better? Simpler workflow, fewer commands, less errors Faster: 2–3 hrs. for 12 FE pool (down from 8–12 hrs.) More reliable Checks for readiness across the pool within the cmdlet before failover Leverages windows fabric v2 deactivate/activate node APIs ensuring more dependable operation (moving replicas in/out, not move replicas into node going down) Since scope is always one frontend, avoids situations where multiple front ends could be down within a pool (reason servers don’t start) Will not allow fail over of a server if there are existing replica issues in the pool Enforces min server requirements implicitly (if other servers are down) Progress indicators © 2012 Microsoft Corporation.

SQL always on Known issues

Issue 1 Clients go into resiliency mode after failing over Availability Group to secondary replica Reason: The Availability Group wizard does not replicate the SQL logins from the primary node to each of the defined secondary replicas Workaround steps: 1. Launch Topology Builder and download topology 2. Change the SQL machine FQDN value to the AG Listener FQDN 3. Publish the topology and wait for CMS replication to occur 4. Use Cluster Manager to failover the AG Listener cluster resource to one of the replica servers 5. Run Install-CsDatabase –Update (which creates the missing SQL logins on the replica server) 6. Repeat steps 4–5 for each additional replica server Note: If you want to create a new database you will need to repoint the SQL Machine FQDN to the Primary Node in the Availability Group RTC Universal Groups are missing

Issue 2 Unable to move from SQL mirroring to AlwaysOn Availability Groups due to location of CMS database Reason: If the CMS database is homed on or paired with the pool where you are attempting to move to AlwaysOn Availability Groups, you will be unable to change the HA model for the backend database Workaround steps: If the pool is not paired, use the Move-CsManagementServer cmdlet to move the CMS database to another pool. If the pool is paired and the CMS is not homed locally on the pool where you are attempting to change the backend HA model: Disable pool pairing and uninstall the CMS database Change the HA model from SQL mirroring to Availability Groups Reinstall the CMS database and re-enable pool pairing Add the CMS databases to the Availability Group If the pool is paired and the CMS is homed on locally on the pool where you are attempting to change the backend HA model: Use Invoke-CsManagementServerFailover cmdlet to failover the CMS database

Issue 3 Creating an Availability Group with only a single replica
Reason: For test environments, you may want to create an Availability Group with only a single replica. If you attempt to use SQL Management Studio to do this, you will be blocked as it requires a minimum of two replicas. However, you can use PowerShell to work around this limitation Workaround steps: Use the powershell cmdlets to set this up # Create an in-memory representation of the primary replica $primaryReplica = New-SqlAvailabilityReplica -Name "lab2-sql5\Instance1" -EndpointURL "TCP://lab2-sql5.contoso.com:5022" -AvailabilityMode "SynchronousCommit" -FailoverMode "Automatic" -Version 12 -AsTemplate # Create the Availability Group New-SqlAvailabilityGroup -Name "MyAG" -Path "SQLSERVER:\SQL\lab2-sql5\Instance1" -Database "cpsdyn" # Add additional database to the Availability Group Add-SqlAvailabilityDatabase -Path "SQLSERVER:\SQL\lab2-sql5\Instance1\AvailabilityGroups\MyAG" -Database "rgsconfig" Add-SqlAvailabilityDatabase -Path "SQLSERVER:\SQL\lab2-sql5\Instance1\AvailabilityGroups\MyAG" -Database "rgsdyn" Add-SqlAvailabilityDatabase -Path "SQLSERVER:\SQL\lab2-sql5\Instance1\AvailabilityGroups\MyAG" -Database "rtcab" Add-SqlAvailabilityDatabase -Path "SQLSERVER:\SQL\lab2-sql5\Instance1\AvailabilityGroups\MyAG" -Database "rtcshared" Add-SqlAvailabilityDatabase -Path "SQLSERVER:\SQL\lab2-sql5\Instance1\AvailabilityGroups\MyAG" -Database "rtcxds" # Add Availability Group Listener (note port number - you will get an error if default SQL port 1433 is already in use) New-SqlAvailabilityGroupListener -Name lab2-sqlclu1 -StaticIp ' / ' -Path "SQLSERVER:\SQL\lab2-sql5\Instance1 \AvailabilityGroups\MyAG“ -Port 1431

Issue 4 Clients go into resiliency mode after failing over Availability Group to secondary replica Unable to create AlwaysOn Availability Group Listener due to connection failure Reason: The Availability Group wizard does not replicate the SQL logins from the primary node to each of the defined secondary replicas. Reason: For named instances, SQL Server listens for connections on a dynamic TCP port. Some admins may wish to configure SQL to listen on either the default port (TCP/1433) or use a SQL alias to configure SQL to listen on a non-default static port (e.g., 1499). If you configure your SQL Servers to listen on the default port, you will encounter an error when attempting to create the Availability Group listener for SQL AlwaysOn due to a port conflict Workaround steps: Use a SQL alias to configure SQL to listen on a non-default static port (e.g.,1499) if default SQL port 1433 is already in use ( Verify that exceptions have been added in Windows Firewall for the port used by the Availability Group Listener
