This article discusses issue that you must consider when you use mounted folders together with versions of Microsoft SQL Server in stand-alone and clustered environments.
The availability of support for mounted folders depends on the version of SQL Server and on whether the instance of SQL Server is a stand-alone or clustered instance:. Note Mounted folders are also known as any of the following:. However, the SQL Server Setup program requires the base drive of a mounted drive to have an associated drive letter. If the base drive of a mounted drive does not have an associated drive letter, the Setup program will assign the next available drive letter to the drive.
Note If all the drive letters are already assigned, the Setup program will fail. For more information, click the following article number to view the article in the Microsoft Knowledge Base:. The clustered installations of SQL Server are limited to the number of available drive letters. Therefore, if you use only one drive letter for the operating system, and if all other drive letters are available as normal cluster drives or as cluster drives that are hosting mount points, you are limited to no more than 25 instances of SQL Server per failover cluster.
A mounted volume, or mount point, lets you to use a single drive letter to refer to many disks or volumes. For example, if you have a drive letter R: that refers to a regular disk or volume, you can connect or "mount" additional disks or volumes as directories under drive letter R: without the additional disks or volumes requiring drive letters of their own.
Additional mount point considerations for SQL Server failover clustering include the following:. SQL Server Setup requires that the base drive of a mounted drive has an associated drive letter.
For failover cluster installations, this base drive must be a clustered drive. Volume GUIDs are not supported in this release. The base drive is the drive that is assigned the drive letter. The base cannot be shared among failover cluster instances. This is a usual restriction for failover clusters but is not a restriction on stand-alone, multi-instance servers.
Be careful when you set up your failover cluster to make sure that both the base drive and the mounted disks or volumes are listed as resources in the resource group. SQL Server Setup validates drive configuration as part of a failover cluster installation. Note As a best practice, do not use the letters A or B for a cluster. However, this reduces the number of possible instance to 23 instances per cluster.
Mount points and the host drive must be displayed as a cluster physical disk resource. Additionally, the physical disk that has a drive letter and each mounted volume must also be added as a SQL Server dependency.
If you perform a new installation, the correct dependency permissions are set on the physical disks that have an associated drive letter and on the mount points. The dependency permissions are set automatically during setup. This includes the cumulative update and the required service pack.
Important If you use a merged slipstream, that version of the slipstream must remain available in its original location as long as the instance of SQL Server exists. Additionally, you must set the correct dependencies in installations that are missing the required dependencies. If only the root physical disks dependency is added and the mount points dependency is not added, database corruption will occur on failover.
Database corruption may also occur during a SQL Server restart should disk resources go offline and return to online state even without failing over.
Warning If you previously installed SQL Server to a root directory, you may be unable to install service packs or cumulative updates. Cluster Shared Volumes. Create a dependency in the mounted volume disk resource that specifies the disk that is hosting the mount point folder.
This makes the mounted volume dependent on the host volume, and it makes sure that the host volume comes online first. Note In Windows Server and later versions of Windows, this practice is no longer necessary. If you move a mount point from one shared disk to another shared disk, make sure that the shared disks are located in the same group. Try to use the root host volume exclusively for mount points. The root volume is the volume that hosts the mount points.
This practice greatly reduces the time that is required to restore access to the mounted volumes if you have to run the Chkdsk. This also reduces the time that is required to restore from backup on the host volume.
If you use the root host volume exclusively for mount points, the size of the host volume must be at least 5 megabytes MB. This reduces the probability that the volume will be used for anything other than the mount points.

There are some grammatical errors where at times you have to reread the sentence to understand the point the author is trying to make but overall this is not that bad and you can generally figure out the meaning.
The very frustrating part is that the examples are inconsistent. In some cases there are very clear instructions on how to do a specific part in the 'Time for Action' examples and in other cases it just instructs you to do something, without any direction, so the reader is stuck trying to figure out what to perfect photo 9 free. At times I am left frustrated and I have to walk away and come back to it. In other cases it appears the author just took for granted that after you have done something one time way back in the beginning читать далее the book you will remember it pages later.
It doesn't necessarily have to be spelled out but at least having a reference to the page where the previous action took place would be nice. This book is also very syntax driven. I understand this is a beginner's book but I just expected more of an explanation on why AND how things are done.
The first part of the book talks about building the Data Warehouse but it doesn't explain in very much detail about how the dimension and fact tables were constructed, what читать статью the methodology behind it and why they were designed the way they were. To me that is important information to understand and this book just gives you a link to an already created data warehouse that you download and use.
To me it would have been MUCH more helpful to guide the reader продолжить чтение the actual creation microsoft sql server 2014 business intelligence development free the data warehouse so that a clear understanding of why the dimension and fact tables were created and the path to get to that point.
I microsoft sql server 2014 business intelligence development free not recommend this book for someone who is trying to understand the concepts of creating a data warehouse. As a book about how to perform actions once it is created it is ok for that, but microsoft sql server 2014 business intelligence development free great. As others mentioned, it feels like a walkthrough that doesn't include a как сообщается здесь of detail. The author also seems to take it for granted that you have installed both MDX and Tabular editions of SSAS they're mutually exclusive on a server and jumps from one to the other по этому адресу in the book.
However, more frustrating is that seems like nobody actually walked through the exercises when the book was complete. However, he neglects to tell you that you need to process things on the server before any data will appear.
When Creating your SSIS package, there is a typo in the database name, causing you to use the wrong name in one place. Report abuse. This is not a good beginners guide. It does not explain why all these steps are being done. I tried the sample book before purchasing; it read with promise. However, the sample really oversells it.
I don't recommend this book. I agree about the grammar errors but overall a great book if your starting out and trying to understand Business Intelligence.
