Summary |
Safeguard your business assets
Synology RS3621RPxs is a powerful 12-bay storage server. Its 6-core processor enables compute-intensive services while its redundant power, ECC memory, and Btrfs file system safeguard mission-critical data. Capable of delivering 189,098 4K random read IOPS and 4,718 MB/s sequential read throughput1, it is ideal for small businesses.
Reliability first
Service continuity is at the core of the RS3621RPxs design.
Redundant power
Dual PSUs provide protection against a PSU failure or accidental cord removal while hot-swappable fans can be replaced without powering down the system.
Near-zero downtime
Synology High Availability (SHA) pairs two identical units together creating an active-passive cluster with minute-level failover.
Next-generation file system
Btrfs prevents data corruption and reduces maintenance overheads with advanced storage technologies and optimized snapshots.
Customize to suit
The two built-in PCIe slots allow users to customize the RS3621RPxs to satisfy unique performance, networking, and storage requirements2.
10GbE ready
Support for 10GbE NICs expands the throughput of the unit by up to 5x times using link aggregation.
SSD cache3
Boost read/write IOPS by up to 16 times by enabling SSD cache via our Synology M.2 NVMe adapter cards and SNV3000 Series SSDs or by installing one or more 2.5” SAT5200 SSDs.
On-demand drive bays
Expand to 36 drive bays using two RX1217(RP) expansion units with minimal intervention.
Hyper Backup
A comprehensive backup and recovery solution for securing data stored on Synology servers. Backup data locally, to another Synology device, rsync server, or cloud-based storage such as Google Drive, Dropbox, S3-compatible destinations, and Synology C2. Deduplication4, integrity checks, and incremental transfer technology reduce bandwidth and storage used.
Snapshot Replication
Easily schedule flexible point-in-time backups of shared folders and iSCSI LUNs with an RPO as low as 5 minutes and recovery in seconds. Set up replication and failover to other Synology storage systems for fast RTOs and minimal service disruption.
Storage for virtualization
Synology iSCSI storage supports mainstream virtualization solutions with an easy management interface to enhance usability. VMware vSphere 6.5 and VAAI integration helps offload storage operations. Windows Offloaded Data Transfer (ODX) speeds up data transfer. OpenStack Cinder support turns your Synology NAS into a block-based storage component. Additionally, Synology Storage Console enables even more simplified storage provisioning and management options in VMware and Windows environments
Works best with Synology drives
Engineered to handle intensive 24/7 workloads, Synology drives consistently deliver top-grade performance. |
