How many Enterprise Licenses to Buy?

We are building up a clustered server configuration with two nodes. Each
node will be an HP ML580 or DL 580 with 4 processors per server. Do we need
to buy two Enterprise licenses (one for each 4-processor server) or 8
licenses (one for each processor on each server)? I am getting conflicting
information on this. Thanks for any info.
How many instances are you going to run in the cluster? You license per active instances (unless you
will run several instances in the same node, i.e., the other node doesn't do any SQL Server
processing at all). And, if you license per processor, you need to multiply with the number of
processor sockets you use in the machine.

|||It depends.
First, check with your local Microsoft office. Make sure you have a person
knowledgable about SQL licensing in a clustered environment.
Here is the base page with links to the licensing information:
http://www.microsoft.com/sql/howtobuy/default.mspx#EEAA
Here is the FAQ page
http://www.microsoft.com/sql/howtobuy/faq.mspx
The relevant question and answer are here:
Q. How does licensing work for computers that run SQL Server 2005 in
failover scenarios?
A. Failover support, where servers are clustered together and set to
pick up processing duties if one computer should fail, is now available in
Workgroup, Standard, and Enterprise editions of SQL Server 2005. Under each
of these editions, keeping a passive server for failover purposes does not
require a license as long as the passive server has the same or fewer
processors than the active server (under the per processor scenario). For
details on which failover methods are available under each edition, visit
the SQL Server 2005 Features Comparison page.
Finally, SQL 2005 supports failover clustering on Standard Edition with up
to four processors on each host. If you do not need any other Enterprise
Edition features, you will save a considerable amount of money on licensing
by using Standare Edition. Oh, and look at the DL/ML 585 series wutl
Dual-Core processors. IMHO, the best bang for the bucks.

As for the licensing, since you don't have any internet access to the
server, choose whichever licensing model (per-processor or CAL) is cheaper.
That is why Microsoft has multiple licensing models.

your help. I don't think our software supplier is asking us the right
questions, as they went straight for the per-processor option even though the
device CALs option is much better suited for our situation.

There is no technical enforcement measure for CAL enforcement built into SQL

configuration through that so you have a single point of maintenance.

How many drives can be mapped to 2 SQLServer on cluster

Dear all,

We have just configured a SAN system and 2 SQLServer clustered(A/P).

The vendor has mapped 2 logical drives each one is accessed by each SQLServer

ex:

Logical Drives on SAN :- H: and G:

Server S1 have accesses to H: and Server S2 have accesses to G: but at a time we can see both logical drive on each system but can access there mapped drives.

Is this possible to have 2 logical drives on each server mapped with each other on the cluster server.

Server 1 having drive H: and G:

Server 2 having drive H: and G:

Note : Vendor told us that there is a BUG in SQLServer 2005 that only one drive can be mapped with each sqlserver in a cluster.

Please help

Is there can Document Released from Microsoft Regarding Clusting SQLServer2005 Please the link.

Regards

Mohd Sufian

This is not a bug, but functionality. You can only add one drive to each cluster group. If the drive is already used by one SQL server instance, you can not use the same with other instance.

Here is a webcast on 'How to custer SQL Server 2005':

http://support.microsoft.com/kb/891798

And here is a white paper:

http://www.microsoft.com/downloads/details.aspx?FamilyID=818234dc-a17b-4f09-b282-c6830fead499&DisplayLang=en

|||This is technically not a problem with SQL. Most SAN's don't allow you to point more than 1 computer to 1 logical volume on the SAN.

How licences work in a backup computer

Hello,
I have found that if you have a clustered and log-shipping environtment you
don't have to buy licences for the passive computer. But in my environtment
I have the main server and then more computers with SQL Server installed but
not used (the service stopped), but in case of failure of the server, I can
restore the backup database on one of this other computers to continue
working.
I suppose that it's the same case than in clustered and log-shipping, if I
just use only one SQL Server at a time, I only have to buy licences for one
server. But I haven't found anything of than in Microsoft site. Does anyone
know how it works?
Thank you in advance,
Josep.The way I had it explained to me was that if the "standby" instance don't do any work normally, then
it doesn't need a license. And that this is regardless of what technology you are using. But I'd ask
an MS rep to be certain...
