What is a cluster in storage?
2) In personal computer storage technology, a cluster is the logical unit of file storage on a hard disk; it's managed by the computer's operating system. Any file stored on a hard disk takes up one or more clusters of storage. A file's clusters can be scattered among different locations on the hard disk.
What is cluster server and how it works?
A server cluster consists of a group of servers working simultaneously under a single IP address. Clustered servers are commonly used for servers that include files, prints, databases, and messages. These clusters increase data protection and maintain the consistency of cluster configuration over time.

How is data stored on a cluster?
Most of the data on a cluster is kept in separate storage units that have multiple hard drives. These units are called file servers. A file server is a computer with the primary purpose of providing a location to store data. Regular users do not login to file servers.
Can one file stored in more than one cluster?
In Microsoft's operating system (like DOS, WINDOWS, etc.), the smallest unit of file management and storage, is called "cluster". A file is usually stored in one or more clusters. But it should occupy a "cluster" at least. That is to say two files cannot be stored in the same cluster.
How do computer clusters work?
A computer cluster is a set of connected computers (nodes) that work together as if they are a single (much more powerful) machine. Unlike grid computers, where each node performs a different task, computer clusters assign the same task to each node.
Can a cluster contain more than one file?
As you'll recall, clusters are the smallest unit of storage space on a hard disk. This means that you can't share a cluster among multiple files. If you have a tiny file and a huge cluster, the portion of that cluster unused by the file is wasted.
Why should domain level groups be used in defining share level permissions?
Only domain level groups should be used in defining share level permissions because local groups and user accounts do not reside on the other node, and the permissions will not take effect when the file share is failed over. The only exception to this is if all nodes in the cluster are domain controllers.
What is a share name in NetBIOS?
The "Share Name" is the name of the share that will be created for the UNC when clients connect. This needs to be a valid NetBIOS name, and is recommended to be a valid URL name as well.

What is a cluster shared volume?
Each Cluster Shared Volume hosted on a coordinating node cluster creates a share with a name that looks like a GUID. This is used by CsvFs to communicate to the hidden CSV NTFS stack on the coordinating node. This share points to the hidden NTFS volume used by CSV. Metadata and the File System Redirected IO are flowing to the Coordinating Node using this share.
What is the node for clustered CSV disk?
The node where NTFS for the clustered CSV disk is mounted is called the Coordinator Node . In this context, any other node that does not have clustered disk mounted is called Data Servers (DS). Note that coordinator node is always a data server node at the same time. In other words, coordinator is a special data server node when NTFS is mounted.
Why is clustering important?
Cluster guarantees that only one node has NTFS in the state where it can write to the disk, this is important because NTFS is not a clustered file system . CSV provides a layer of orchestration that enables NTFS or ReFS (with Windows Server 2012 R2) to be accessed concurrently by multiple servers.
What is a CSV namespace filter?
The CSV Namespace Filter (CsvNsFlt.sys) is a file system mini-filter driver at an altitude of 404900:
Can you create multiple volumes on a disk?
In practice, you can create multiple volumes on a disk and CSV fully supports that as well. When you move a disk ownership from one cluster node to another, all the volumes will travel along with the disk and any given node will be the coordinator for all volumes on a given disk.
Can you see hidden shares in CSV?
There are also couple hidden shares that are used by the CSV. You can see them if you add the IncludeHidden parameter to the get-SmbShare cmdlet. These shares are used only on the Coordinator Node. Other nodes either do not have these shares or these shares are not used:
Can node 1 and node 2 see disk?
Both Node 1 and Node 2 can see the shared disk - they can send reads and writes directly to the disk completely avoiding sending data over the network. The Node 3 is not in the diagram on the Figure 7 Direct IO Flow since it cannot perform Direct IO, but it is still part of the cluster and it will use block level redirected IO for reads and writes.#N#The next diagram shows a File System Redirected IO request flows. The diagram and data flow for the redirected IO is very similar to the one for the metadata from the Figure 6 Metadata Flow:
How to add a new disk to a cluster?
Right-click the new available disk in FCM and select Add To Cluster Shared Volumes. The disk will go offline for a second and then reappear back online as a new CSV. Note that the volume is now mounted under what looks like a folder (see Volume1 in the below screen shot) in C:ClusterStorage on each node in the cluster that has access to the disk.

Why use CSV in failover clustering?
CSV was added to failover clustering in W2008 R2 to provide a file system that could be shared and active across each node in the cluster. This means that you can store lots of virtual machines one a few easily managed volumes (try to have one per cluster node) and run those virtual machines across any or all of the cluster nodes. The W2008 R2 version of CSV was restricted to being used just for storing Hyper-V virtual machines. Windows Server 2012 (WS2012) expanded this to include the SOFS, and Microsoft continues to evaluate other scenarios where CSV can be of use.
What is a LUN in a cluster?
The LUNs are zoned/connected to every node in the cluster. At this point, the LUN is only accessible by one of the nodes in the cluster (known as shared-nothing).
How many CSV files per LUN?
Create and format a new volume that fills the LUN; you should have one CSV per LUN. Do not assign a drive letter to the volume; the CSV will be mounted in the C:ClusterStorage folder on each node instead.
Who creates CSV owner?
Don’t worry about the CSV owner role. It is created by Windows for you and managed by Windows. The role is highly available.
How to create a volume in Azure Stack?
First, launch Windows PowerShell from the Windows start menu. We recommend using the New-Volume cmdlet to create volumes for Azure Stack HCI. It provides the fastest and most straightforward experience. This single cmdlet automatically creates the virtual disk, partitions and formats it, creates the volume with matching name, and adds it to cluster shared volumes – all in one easy step.
How many parameters does the new volume cmdlet have?
The New-Volume cmdlet has four parameters you'll always need to provide:
What is Azure Stack HCI?
To help you create such volumes, Azure Stack HCI provides default tier templates called MirrorOnMediaType and NestedMirrorOnMediaType (for performance), and ParityOnMedia Type and NestedParityOnMediaType (for capacity), where MediaType is HDD or SSD. The templates represent storage tiers based on media types and encapsulate definitions for three-way mirroring on the faster capacity drives (if applicable), and dual parity on the slower capacity drives (if applicable).

What is a CSV in Server 2012?
In Windows Server 2012 Cluster Shared Volumes (CSV) has been more tightly integrated into the Failover Clustering feature. The process for a cluster Physical Disk Resource (PDR) to be enabled for CSV has been simplified and streamlined. In this blog, I will show you the new experience of adding storage from the Available Storage pool of your cluster to Clustered Shared Volumes. The Available Storage pool contains disks that have been added to your cluster but not assigned to a specific use in your cluster.
