Inline Deduplication and Compression

DataCore Inline Deduplication and Inline Compression provides several unique advantages for capacity optimization. By using one set of deduplication resources for all disk pools and corresponding virtual disks on a server, shared storage can be extended among the greatest number of sources. This provides tremendous flexibility in terms of deployment and use, while also maximizing the storage savings.

While using Inline Deduplication and Inline Compression, it is vital to monitor the remaining Capacity Optimization space that is available per server. If the system exhausts the available Capacity Optimization storage, it will cause the dependent disk pools to go offline, and all dependent virtual disks to fail on the corresponding server. In addition, performance for Capacity Optimization enabled virtual disks will suffer when the available space drops below 15%. See Tracking Capacity Optimization for more information.

To achieve the best results while using Inline Deduplication and Inline Compression, there are some important things to consider. The first, Capacity Optimization in and of itself does not provide any fault tolerance. DataCore recommends using storage with built-in redundancy built into it, such as a RAID configuration. In addition, DataCore recommends using at least two physical disks per server for Capacity Optimization storage. Dedicating only one physical disk can cause inconsistent performance on Capacity Optimization enabled virtual disks.

DataCore Inline Deduplication and Inline Compression is only supported on Windows Server 2016 and later.
