Secure storage for your business
Synology RS2421+/RS2421RP+ are versatile 2U 12-bay storage servers designed to accommodate a diverse set of business environments. Scalable up to 24 drives, they are designed for cost-effective file management and sharing and include powerful backup capabilities designed for businesses with a growing data footprint. The unit delivers 2,200 MB/s 64K sequential read and 1154 MB/s sequential write performance, and can be optionally enhanced with SSD cache and 10/25Gb .
High performance storage for anything
Over 106K/59K random read/write IOPS and up to 2,200/1,154 MB/s sequential read/write throughput ensure ample performance for demanding workloads.
Built for reliability
Redundant power
Reduce the possibility of power disruptions on a single distribution channel or PDU adversely impacting data and service availability.
Near-zero downtime
Pair two identical devices with Synology High Availability and enable automatic minute-level failover between both devices in the event one server fails.
Data integrity and protection
ECC memory brings higher system reliability, while the Btrfs file system helps prevent data corruption, supports snapshot technology, and simplifies data protection.
Customize to suit
Easily adapt the RS2421+/RS2421RP+ to any business environment by adding er networking, local SSD cache, or storage capacity.
10/25GbE ready
Support for 10/25GbE NICs lets you boost maximum network throughput using Link Aggregation (bonding).
Hyper Backup
Back up files, iSCSI LUNs, installed applications, and system configurations to destinations including Synology C2 Storage, public cloud platforms, USB devices, file servers, local folders, or other Synology NAS.
Set and forget backup tasks with regular schedules, enhance security with fine-grained user permissions and encryption, keep backup sizes small with built-in deduplication5, and restore data flexibly with multi-versioning.
Snapshot Replication
Snapshot Replication enables flexible point-in-time snapshots of shared folders and virtual machines with an RPO as low as 5 minutes and recovery within seconds.
Serving remote workforces
Keep your remote workforce connected with powerful out-of-the-box solutions for collaboration, file sharing, and communication.
Storage for virtualization
DSM streamlines provisioning for and management of virtual machines with full certification for VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack virtualization environments.
Synology Storage Console for VMware or Windows platforms lets you manage storage directly from your hypervisor. VMware VAAI integration and Windows ODX help offload storage operations and speed up data transfer.
