Flash volume deduplication
Remove duplicate data on all-flash arrays with volume-wide deduplication to greatly increase storage efficiency. Eliminate redundant data to save up to 65% in storage space use in applications like virtual desktop infrastructure, and virtual machine.3
Complete virtualization platform
Deploy the FS2500 as fast and efficient VM storage and benefit from free native hosting, management, and protection tools in Synology DiskStation Manager (DSM).
Deploy and facilitate storage operations in various virtualization environments with full certification for VMware® vSphere™, Microsoft® Hyper-V®, Citrix® XenServer™, and OpenStack, and a Kubernetes CSI driver for integrated volume management.
VM and container storage on all-flash arrays can benefit from volume-wide data deduplication, a technology that removes identical data to optimize storage use.3
Synology Virtual Machine Manager (VMM) is a hypervisor for Windows® and Linux® VMs or Virtual DSM, a virtualized version of DSM.4 Use your Synology device as an alternative host for VMs to quickly recover services following failure or run failover copies of PCs, servers, and VMs created with Active Backup for Business (ABB), DSM’s data protection tool for physical and virtual environments. Learn more
Manage storage directly from your hypervisor with Synology Storage Console for VMware® or Windows platforms, provision volumes directly from the Kubernetes CLI, and offload storage operations and speed up data transfer through VMware® VAAI integration and Windows ODX. Learn more
