Simple Understanding of Lync/Skype For Business Windows Fabric & Failover

Howdy,

I saw a scary number of Lync 2013 deployments in the last 8 months where the Lync is deployed using an Enterprise pool with only two front end servers, even I saw a couple that have an Enterprise pool with only one front end server, yes you read that right, only one front end server.

So I decided to write another post of my “Simple Understanding” article series aimed to explain the Lync 2013 server architecture, how it utilize windows fabric for high availability and why you should not deploy a 2 nodes Enterprise Edition pool, I’ll try to use small words and simple explanations as I can.

I’m planning also to use this article as a guide to share with customers which have an existing Lync deployment or considering Lync to help them in their decisions.

Migrate Lync 2013 Standalone SQL Store to SQL Mirrored Store Step – By – Step PART-II

Howdy,

In Part-I I wrote about what we can call “Preparation” to migrate the standalone SQL to Mirrored SQL,

Next is to define new SQL Mirrored Store for the enterprise Pool, install the mirrored database and move back the Central management store and server back to the Enterprise Pool and decommission the Standard Edition Pool.

Note: again, I had to do that, because my client wanted to decommission the current Standalone SQL hosting the Lync Enterprise SQL store, and used also by other technologies, they wanted to move the database to dedicated SQL store used only by Lync.

If you just want to make your Standalone SQL a Mirrored SQL store, all you need is to prepare one more SQL 2012 Server (or two in case you want a witness for Automatic failover – check Part-I) and carry on with following steps without moving the CMS to another Pool.

Migrate Lync 2013 Standalone SQL to SQL Mirrored Store Step – By – Step PART-I

Howdy,

I got a request to move the SQL backend store of a Lync 2013 Enterprise Edition pool deployment, from a standalone to a dedicated Mirrored SQL Servers Store for high availability.

Was an interesting task as I am very bad with SQL technologies, so I researched and did my homework and tested it in my lab, before I applied it to the customer which was a good success, so I thought I will write a How-to , step by step to the point guide to help anyone that might have to do so one day 🙂
