Hyper-V Server storage tiering

In addition to basic storage virtualization and management, Windows Server R2 Storage Spaces (storage space) can protect data by using snapshots and failover capabilities to support storage availability. Storage spaces use data fragmentation (RAID 0), where data is placed on different disks in segments, and the entire array of disks can read and write simultaneously, improving disk performance. When there is a problem with the disk, it can be rebuilt with an alternate storage space. Regular background scanning can proactively check and correct disk problems, thereby enhancing data integrity.

Windows Server R2 has a variety of functional improvements in storage space. The most notable is the use of data deduplication to improve performance while minimizing storage capacity requirements. The new features of storage spaces in Windows Server2012 R2 include:

1. Storage tiering: Storage tiering allows storage space to create virtual disks using mechanical or solid media, and then transfer the data to the medium that best fits the data usage pattern. For example, frequently accessed data can be dynamically targeted to an SSD thermal layer, while less-accessed data is targeted to the cold layer using the SAS HDD standard. Data can also change the storage location based on changes in the data access pattern. It or storage administrators can also place data directly on the required tiers.

2. Write-back caching: The write-back cache caches new data to the storage array instead of waiting for the physical disk to complete the write operation. This improves storage write performance, allows applications to resume work faster, and reduces I/O traffic for storage networks and subsystems, which is useful in shared storage deployments and hierarchies.

3. Parity space support for failover clusters: Create parity spaces in the failover cluster.

4. Double parity check: Windows Server R2 Storage supports dual parity, which detects and recovers two synchronous disks (not individual disks). When a failure occurs, the disk can be rebuilt quickly using excess storage space, minimizing the impact on storage performance during lengthy disk rebuilds.

5. Automatically rebuild storage space from the storage pool free space: Use the standby capacity in the pool instead of a single hot spare to reduce the time it takes to rebuild storage space after a physical disk failure.

Create a storage hierarchy for storage spaces

1. Log on to the server "bj-vmhost-02", open the Server Manager, click on the file and storage services, click on the disk, confirm that there is a physical disk available
