Lync 2013 SQL requirements

I have a SQL environment which is used for web apps, ERP, CRM and other databases. Can I install my Lync SQL environment onto this SQL server? is this scenario supported?
or do I need dedicated and separate Lync SQL servers?

It's recommended to use a separate SQL server for Lync (Physical of Virtual), however collating Lync database with other SQL databases will work. Considering the cost of SQL licenses, this is not uncommon.
It is important in either scenario that the SQL servers have adequate resources/performance to be able to handle the load from Lync server in addition to anything else it will be doing.
Also note that if you have multiple front end pools, these cannot share a SQL server. (and creating another instance on the same SQL server also does not work)
Take a look at the Technet information for more: http://technet.microsoft.com/en-us/library/jj205112.aspx and http://technet.microsoft.com/en-us/library/gg398835.aspx

CMS Movement from Lync 2010 to Lync 2013 SQL Mirroring

Hi,
I have read the articles and i know how to move CMS to Lync 2013 , MY question is after moment CMS to Lync 2013 , the new DBs on SQL server will be mirrored automatically or i have to apply some procedure to make them mirror.
Regards
Usman Ghani

Good morning,
If the new Lync 2013 Enterprise Pool you deployed has a mirrored backend, then when you move the CMS to that instance the database will inherently be mirrored. There is no requirement to perform any additional action or procedure.
This assumes that you have an enterprise Lync 2013 deployment as a mirrored CMS would not be available on a standard edition deployment.
Kind regards
Ben

Lync 2013 Deployment Requirements - One Server?

I have an organization that has an offsite Exchange Server 2010, and Windows Server 2008 R2 Domain Controller (for the Exchange Server).
I am trying to figure out what we need for hardware and Windows Server software to implement Lync 2013. I understand that Lync 2013 cannot be put on the same server as the Exchange Server. Can Lync 2013 be put on one Windows server?
Michael

Depends. Without knowing a lot about your environment (i.e users, HA requirements) ideally you'd have two. One as a Lync Standard Edition server (which can support up to 5000 users for Front End Services and Back-End database - but won't have HA) and one
as an Lync Edge server (for outside connectivity - also won't have HA)
Standard Edition will use SQL express as its database and automatically install it on the single server.
As for operating system Windows 2008 R2 or above.
As for hardware you can use this as a guide: http://technet.microsoft.com/en-us/library/gg398835.aspx and use the Lync Capacity planning tool http://www.microsoft.com/en-us/download/details.aspx?id=36828
How many users do you have? (for example the first link has 32GB as recommended memory for a Front End, but if you don't have many users you can use less than that - and the Cap Planner will reflect that)

Lync 2013 SQL Permission after install

We have started to install Lync 2013 Enterprise to replace our Lync 2010 Standard servers. Since we are moving to enterprise I've had to ask the SQL dba to get envolved with the installation. We followed the recommended permission document here..
http://technet.microsoft.com/en-us/library/gg398375.aspx
we gave the install account Sysadmin and local admin on the SQL server.
Now that the install is complete our dba wants to remove sysadmin from the account and remove it from SQL.
Can we do that or does it need to stay in place?
Thanks,
Matt

Hi Matt,
You should be able to remove it now that the databases have been created as it should only be required for installation. You just need to make sure that your users accounts for management are part of the appropriate RBAC groups.
The only caveat I can think of is if you need to do some SQL configuration tasks like deploy mirroring or run an update that may need to drop and rebuild the database. In those scenario you would need to have it reapplied.

Lync 2013 sql database on existing lync 2010 sql server

Dear All,
I have query regarding the SQL server requirement for Lync 2013 enterprise,when there is a co-existence or migration from lync 2010 to 2013, it it possible to use the same Lync 2010 enterprise sql server with different instance name or we have to create
a new sql server for lync 2013, please advice me.
Thanks and regards,
sarma kumar

No it is not possible. Topology builder won't allow it, it needs to be a completely different server name.
When you input the server into Topology builder you enter the server name and instance in two separate fields, it will give you a red X as soon as you try to put the server name in if it's already in the topology.

Lync 2013 certificate requirements for multiple SIP domains

Hi All,
I am engaged with a client in respect of a Lync 2013 implementation initially as a conferencing platform with a view to enabling EV functions (inc. PSTN conferencing) in the future. They initially need to support 30 SIP domains and eventually
around 100 SIP domains which is proving to be either not possible or severely cost prohibitive. Their current certificate provider, Thawte, can only support up to 25 SANs and have quoted them 5 figures. We tend to use GeoTrust as they are cheaper but they
appear to have a limit of 25 SANs. GoDaddy appear to support up to 100 SANs for a pretty reasonable cost. My questions are as follows:
Is there a way that I’m missing of reducing the number of SANs required on the Edge server?
Use aliases for access edge FQDNs - Supported by desktop client but not by other devices so not really workable
Don’t support XMPP federation therefore removing the need for domain name FQDNs for each SIP domain
Is there a way that I’m missing of reducing the number of SANs required on the Reverse Proxy server?
Friendly URL option 3 from this page:
http://technet.microsoft.com/en-us/library/gg398287.aspx
Client auto-configuration:
i.
Don’t support mobile client auto-configuration in which case no lyncdiscover.sipdomain1.com DNS records or SANs would be required.
ii.
Support mobile client auto-configuration over HTTP only in which case CNAME records are required for each SIP domain (lyncdiscover.sipdomain1.com, etc. pointing to lyncdiscover.designateddomain.com) but no SANs are required.
iii.
Support mobile client auto-configuration over HTTPS in which case DNS records are required for each SIP domain and a SAN entry for each SIP domains is also required. This is because a DNS CNAME to another domain is not supported over
HTTPS.
If the answer to 1 and/or 2 is no, are there certificate providers that support over 100 SANs?
How do certificate requirements differ when using the Lync 2013 hosting pack? I would think that this issue is something that a hosting provider would need to overcome.
Would the Lync 2013 Hosting Pack work for this customer? The customer uses SPLA licensing so I think is eligible to use the hosting pack but not 100% sure it will work in their environment given that client connections are supposed
to all come through the Edge where their tenants will be internal and also given the requirement for an ACP for PSTN conferencing.
Many thanks,

Many thanks for the response.
I was already planning to use option 3 from the below page for simple URLs to cut down on SAN requirement.
http://technet.microsoft.com/en-us/library/gg398287.aspx
What are the security concerns for publishing autodiscover over port 80? I.e. Is this only used for the initial download of the discovery record and then HTTPS is used for authentication? This seems to be the case from the following note on the below page:
http://technet.microsoft.com/en-gb/library/hh690030.aspx
Mobile device clients do not support multiple Secure Sockets Layer (SSL) certificates from different domains. Therefore, CNAME redirection to different domains is not supported over HTTPS. For example, a DNS CNAME record for lyncdiscover.contoso.com that redirects
to an address of director.contoso.net is not supported over HTTPS.
In such a topology, a mobile device client needs to use HTTP for the first request, so that the CNAME redirection is resolved over HTTP. Subsequent requests then use HTTPS. To support this scenario, you need to configure your reverse proxy with a web publishing
rule for port 80 (HTTP).
For details, see "To create a web publishing rule for port 80" in Configuring the Reverse Proxy for Mobility. CNAME redirection to the same domain is supported over HTTPS. In this case, the destination domain's certificate covers the originating
domain.”
I don’t think SRV records for additional SIP domain access edge is a workable solution as this is not supported by some devices.
As per the below article:
http://blog.schertz.name/2012/07/lync-edge-server-best-practices/
“The recommended approach for external client Automatic Sign-In when supporting multiple SIP domains is to include a unique Access Edge FQDN for each domain name in the SAN field. This is no longer a requirement (it was in OCS) as it is possible to
create a DNS Service Locator Record (SRV) for each additional SIP domain yet have them all point back to the same original FQDN for the Access Edge service (e.g. sip.mslync.net).
This approach will trigger a security alert in Windows Lync clients which can be accepted by the user, but some other clients and devices are unable to connect when the Automatic Sign-In process returns a pair of SRV and Host (A) records which do not share
the same domain namespace. Thus it is still best practice to define a unique FQDN for each additional SIP domain and include that hostname in the external Edge certificate’s SAN field”.
===================
1. Basically the requirement is to initially provide Lync conferencing services (minus PSTN conferencing) to internal, external, federated and anonymous participants with a view to providing PSTN conferencing and therefore enterprise voice services later.
2. The customer currently supports close to 100 SMTP domains and wants to align their SIP domains with these existing domains. The structure of their business is such that “XXX IT Services” provide the IT infrastructure for a collection of companies who
fall under the XXX umbrella but are very much run as individual entities.
Question:
Would you agree that I’m going to need a SAN for every SIP domain’s access edge FQDN?
Thanks.

Lync 2013: SQL instance - Shared or Not Shared !?

I'll keep this straight to the point... I'm implementing Lync 2013 at my company and we stumbled on one SQL Cluster situation that's causing some questions on the DBA team.
So the situation is....
Background:
We currently have a two node SQL 2008 R2 (SP2) Cluster with two instances in it that are shared for other applications.
Question:
Is it recommended by Microsoft (or any Lync Expert at all) to use one of these instances for Lync 2013 databases, or should it be a separated instance to host Lync 2013 Databases?
Note: If to be created the new instance, that instance will be living in the same cluster.
Thank you all in advance for comments on this.

Thanks to both for the replies. It does help me thinking about the subject.
I've meanwhile opened an advisory case with MS to check what they say about it. (I'm posting the results afterwards of course to share their advice)
I agree with both of you, and in fact I don't really like the idea of having a shared instance for Lync 2013 with other products (specially one of them that's in there that is Sharepoint 2013). I'm quite curious on knowing how will the instance behave once
Sharepoint 2013 decides to "eat up" all the resources...
I think that having the separated instance adds at least 2 very good (and important values) that is:
1 - Security (at the instance level.. no unwanted sysadmin's - we have persistent chat by some God forsaken reason... though I don't like the idea that a DBA with the right knowledge to read our C*O's chat's going around...)
2 - Resource assignment control (better memory control, possibility of "shifting" the instance to another place if necessary + if someone "brings down" the shared instance for any reason, lync can continue to function)
The IO concern regarding lots of SQLServer.exe running around, it's also a valid concern in my opinion, though at IO level is basically the same story because what matters is the DB file read-write operations that are ongoing and that will consume the same
resources either you're in a dedicated instance or separated one...
Still our DBA brings up the fact that we need to use a shared instance for everything and he wants me to put Lync all together with the other DB's (Sharepoint 2013 included...).
What are your thoughts about this?
Thanks once again for your time and comments.

Lync 2013 SQL versus Exchange Archiving

Our organization has setup an internal lab for Lync and is trying to decide what the best option would be for deploying archiving with Lync and what the pros vs cons are.
We currently have one Lync 2013 FE Server and an Exchange 2010 server, which I already know does not support archiving. Would it be best to deploy a SQL server for archiving or upgrade Exchange 2010 to 2013? We can do either, but was is the recommended approach
and best practice/pros/cons?
I was planning on utilizing SQL server as the preferred for approach and so we don't have to upgrade Exchange -- just seems easier and will keep any additional load off the Exchange server and once deployed to a production environment.
Thanks.

Agree with Michael.
This data stored in Archiving database is not searchable, but it can be exported to formats that are searchable using other tools.
You can check the difference between these two archiving options at

Lync 2013 SQL Mirroring

I have Lync server 2013 SQL mirroring in place. My firm is looking to decrease our SQL server count. Can I collocate none Lync databases on the Mirror Lync SQL instance? Thanks.

Hi TTMing,
It’s not recommend collocating Lync Server databases with other databases, this might affect availability and performance.

Lync 2013 SQL Backend Witness replacement

Can we replace backend SQL witness server via lync 2013 topology builder as H/W of existing witness server needs to be released due to some technical reason.
We don’t prefer P2V. I want fresh installation of SQL witness server with SQL 2012 express edition and then move the witness role
What is the procedure for the same?
Please help me for the same

Hi,
deploy the new SQL server which dedicated for Witness. Configure the topology and associate the new SQL server as the witness server and publish. remove the old SQL store which was configured as the Witness form the topology.

Lync 2013 DNS requirements in a multi tenant deployment

Hi All,
We are planning to deploy lync 2013 enterprise in a two site (pool) deployment. Both the sites are separated by a WAN link.
Our primary SIP domain is xyz.com
For site A, we have
1) A pool name siteApool.xyz.com
2) 2 FEs name siteAfe001.xyz.net and siteAfe002.xyz.net
3) A edge for external access siteAedge
For site B, we have
1) A pool name siteBpool.xyz.com
2) A FE name siteBfe001.xyz.net
Site B users will use the edge at site A for external access.
As per the r&d we know that following records are required for external access
Access/webcon/av.xyz.com
_sip_tls.xyz.com
Apart from that we also need following service URL records as well
dialin.xyz.com
meet.xyz.com
admin.xyz.com
sip.xyz.com
Our problem starts here and because we only manage xyz.net dns not the xyz.com dns (its is our public dns), which rises two questions -
1) As both the internal and external users are going to use same service url records (dailin/meet/admin/sip.xyz.com), how can we make sure that when a user uses lync on office LAN the service urls will be resolved by xyz.net dns and will not get routed to
xyz.com (public dns) for dns resolution.
2) As i told we have a two site deployment and we need common service url records (dailin/meet/admin/sip.xyz.com) to be used by user at both site , how can i make sure that when a user at site A ask for dailin/meet/admin/sip.xyz.com it gets routed to
siteApool.xyz.com and when a user at site B ask for dailin/meet.xyz.com it gets routed to siteBpool.xyz.com. We need such functionality to save unnecessary WAN traffic.
Please help me to figure out the most suitable design.
Thanks,
Mohit Taneja

Hi Mohit Taneja,
Some additional information.
About the DNS requirements, you could refer to the following article.
http://technet.microsoft.com/en-us/library/gg398082.aspx
About the network traffic, it depends on where exactly the user is hosted. Central site does not decide the media traffic . If user is hosted in site-B and organize the meeting , media has
to travel via WAN if you don’t have edge server in site-B.
Best regards,
Eric

Lync 2013 sql mirroring with different doamin sql server.

Hi,
can I create lync BE sql mirroring with different domain sql server with one AD forest?
Thanks.

Hi,
You can note the sentence “Using Topology Builder or cmdlets to set up and remove SQL mirroring is supported only when the primary, mirror, and witness (if desired) servers all belong to the same domain. If you want to set up SQL mirroring among servers
in different domains, see your SQL Server documentation.” In the link below:
http://technet.microsoft.com/en-us/library/jj204992.aspx
So I think in Lync server if you use Topology Builder or cmdlets to set up and remove SQL mirroring only if when the primary, mirror, and witness (if desired) servers all belong to the same domain. If you want to set up SQL mirroring among servers in different
domains you may do some steps on SQL server and you can also post a case on SQL forum, thank you for your understanding.

Licensed required for LYNC 2013, Sql, Edge

for 1500 users for IM presence, audio video, HA, DR, archive
proposed design :- archive collacted with backend,
DC:- 2 FE server, 2 Edge server, 2 Sql Mirrored,
DR :- 1 FE, 1 Edge, 1 SQL
is there any flaw in sizing?
Licenses :- 3 FE license, (FE in DR will need license as it is passive?)
3 SQL licenses :- how to calculate it per core, in my case how much core and how many licenses required?
thx

Yes, you'll need 3 Lync licenses (you only license the front end and passive will need to be licensed).
For SQL, yes 3 servers. This article will help calculate your core licensing:
http://www.microsoft.com/licensing/about-licensing/briefs/licensing-by-cores.aspx
Sizing is fine provided everything has adequate resources. 3 FEs in the DC pool is recommended.

LYnc 2013 sql witness collocation

Hi,
I have 1500 users, 3 FE server, 2 edge servers, 2 peristent chat, 2 back end, 1 sql witness.
instead of installing sql witness on separate server, want collocate it with any server, basically want to save the one windows license...any idea?

You can colocate it on any server as long as it's not either of the two SQL servers that you use for Lync. So if you have another SQL server floating around that is not part of your topology and is at the appropriate version (even if it's SQL Express)
you can use that.
