Scale-Out File Server is designed to provide scale-out file shares continuously available for file-based server application storage. Scale-out file shares provide the ability to share the same folder from multiple nodes of the same cluster. This scenario focuses on how to plan for and deploy the Scale-Out File Server.
Scale-Out File Server for application data :
This clustered file server feature was introduced in Windows Server 2012 to store server application data such as Hyper-V virtual machine files on file shares.
It gives a similar level of reliability, availability, manageability, and high performance that you would expect from a storage area network.
All file shares are simultaneously online on all nodes. File shares associated with this type of clustered file server are called scale-out file shares.
It is sometimes referred to as active-active which the recommended file server type when deploying either Hyper-V over Server Message Block (SMB) or Microsoft SQL Server over SMB.
We have one server configured as a domain controller and iSCSI target in this LAB, and two file servers each configured with two 15 GB iSCSI disks.
In the next screenshots, we create an iSCSI disk of 15 GB and iSCSI target. The iSCSI target is configured with the IP addresses of the two file servers. We will repeat these steps for the second iSCSI disk.
Run iSCSI initiator in the two file servers and make a quick connection to the iSCSI target 192.168.1.100. Then the two disks appear in the Disk Management:
Add the File Server Role and Failover cluster feature to each fil server, repeat the following steps in the two file server:
The following steps create the cluster named “server-cluster” and add the two file server to this cluster.
Cluster Shared Volumes (CSV) enable multiple nodes in a failover cluster to simultaneously have read-write access to the same LUN (disk) provisioned as an NTFS volume. With CSV, clustered roles can failover quickly from one node to another node without requiring a change in drive ownership, or dismounting and remounting a volume. CSV also helps simplify the management of a potentially large number of LUNs in a failover cluster.
CSV provides a general-purpose, clustered file system layered above NTFS (or ReFS in Windows Server 2012 R2). CSV applications include: Clustered virtual hard disk (VHD) files for clustered Hyper-V virtual machines
- Scale-out file shares to store application data for the Scale-Out File Server clustered role. Examples of the application data for this role include Hyper-V virtual machine files and Microsoft SQL Server data.
- Add the second iSCSI disk as Clustered shared volume.
Configure the cluster role as a file server role, then choose “Scale-Out File Server for application data”. The access point for the role named “server-scaleout”.
