Accelerate your business operations The 12-bay RS3621xs+ is capable of delivering over 238K 4K random read IOPS and 5,819 MB/s sequential read throughput1— a true enterprise powerhouse. With full power supply redundancy, an 8-core processor, ECC memory, advanced snapshot technology, and file self-healing, the RS3621xs+ provides a reliable foundation to any data-driven business. Storage you can trust The RS3621xs+ keeps your data protected while you concentrate on delivering the best results to your customers — even when disaster strikes. Redundant power Dual PSUs provide protection against a PSU failure or accidental cord removal while hot-swappable fans allow them to be replaced without powering down the system. Maximize service availability 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. Tailored to your business The RS3621xs+ includes two PCIe slots for performance, networking, and storage upgrades enabling it to adapt to any business environment2. Double bandwidth Upgrade network bandwidth in minutes by 2x or more with Synology’s range of 10GbE NICs. SSD cache3 Boost read/write IOPS by up to 16 times by enabling SSD cache with our Synology M.2 NVMe adapter cards and SNV3500 SSDs or by installing one or more 2.5” SAT5200 SSDs. Storage expansion Quickly and easily scale up to 36 drives with two RX1217(RP) expansion units. 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. Active Backup Suite Enables administrators to easily backup the entire IT infrastructure to their NAS, including Windows & Linux workstations and servers, file servers, VMware and Hyper-V virtual machines, and Microsoft 365 and Google Workspace accounts. Backups benefit from deduplication, multiversioning, and optimizations to reduce bandwidth and storage used. 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.
