Hi Experts,

I have two new servers for my SQL DB.
Can you help me to install SQL 2014 in the right way ?
The servers are physical and the DB should be installed on premise.
I have heard the Availability Groups are best here, right ?
Do I need a cluster for it ?

I hope you can guide me with this installation.

The best for what?

Do I need a cluster for it ?
Yes, you do need a Windows Cluster. No, you don't need SQL Server cluster instances.

I want to have my DBs on locally disks on my two sql servers.
But when one fails, the other server should take over without mentioned by the clients.
Is it possible ?

Hi,

From SQL Server 2012, Microsoft introduced ALWAYSON GROUP for High Availability and Disaster Recovery. Depending on your SQL Server version:

Standard: supports two nodes
Business Intelligence: supports two nodes
Enterprise: maximum OS supports

Thanks,

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

You mean, use AlwaysOn for High Availability solution. Yes, it's possible.

Yes I have just two nodes. So STD version is enough.
I want to realize this scenario:

When one node crash, the user should still work.
The DB needs to be the same on both nodes.
When I am correct, this is possible with Availability Groups.

Can you help me step by step to set this up ?
What do I have to install first, second and so on.
Maybe you have a nice video or manual for all.
Since now, I have installed WIN2012R2 on both nodes, with the same partition setup :

C : OS
D: DATA
E: TempDB
T: LOGs

Those node supports that Dung Dinh posted is only matter if you are going to use SQL Server Failover Cluster instances. You won't need node supports if your SQL Server instances are stand alones.

Depends on what kind of solution you'll install for SQL Server.
If it's a Failover Cluster instance then yes, you'll need to add disk resources.
If it's stand alone instances then you don't need to add disk resources.

I want to install AlwaysOn for my SQL solutuion.
So I have to install SQL on each node as a single instance.
Right ?

About storage pools or disks, I cannot add these resources.
My resources just local storage.

Do you have a step by step guide for SQL2014 installation ?

Then stand alone instances should be the solution for you.
You don't need a step by step guide to install SQL Server. Just run setup.exe and follow the wizard.
But once again you can search in internet. Here's the guide from MSDN; SQL Server 2014 install

Yes. An installation in each node. In the end you'll have two SQL Server instances.

Also, make sure you set up a witness for your cluster.  If you're not going with shared storage and an AlwaysOn Availability group deployment, a fileshare witness is what you'll use.  WSFC in Server 2012 and up does a lovely job of dynamic quorum calculation where it will dynamically modify the voting rights of the nodes/witness in order to always maintain an odd number of votes.

You should open a question how to use an internet search engine? :)
MSDN has everything about AlwaysOn. You can start with this one and if you get issues return here so we can help you going through.

Right

For AlwaysOn, nothing. But you can use it for clustering, mirroring or log shipping.

Right.

Yes. AlwaysOn it's a better version of mirroring. In Mirror solution the secondary database is not available. And before you ask here's the MSDN article to set up database mirroring :)

They told me, an ENT version for CALs are not available.

Is it right ?

They're right. Server+CAL is only for Standard and BI editions.
For Enterprise Edition it's only available licensing by Processor.

The listener name, always. The listener will know where the database is (if in the primary or secondary replica).

ok thanks.

now just a question about the share which is needed.
I have read it is used to create backups of the primary DBs.
Can I use a share on one of my SQL nodes, because here I have a partition for backups?
Or is it better to create this share on my netapp storage ?

If you're talking about the share for the initialization then you can use one from your SQL nodes since will be used only once.
