Overview:

RackStationRS1221+/RS1221RP+
A powerful storage solution for businesses and IT enthusiasts with redundancy and service continuity features.

Compact and reliable
The RS1221+/RS1221RP+, at only 30 to 38 centimeters deep, is built for space-sensitive deployments. Boasting over 100K 4K random read IOPS and 2,315 MB/s sequential read, the RS1221+/RS1221RP+ is equipped to handle heavy workloads in data-intensive environments. The RS1221RP+ additionally features an extra level of protection with redundant power supplies.

Features:

A compact design for space efficiency
The RS1221+ and its RX418 expansion units are designed to help you save space in compact deployments. At only 30 centimeters, half the length of a typical 2U unit, it fits perfectly snug onto 2-post or shallow rackmount enclosures. The RS1221RP+ with dual power supplies comes in at 38 cm, also fitting most shallow depth enclosures.

• Fits into shallow rackmount enclosures
• Easy-to-install on 3-post racks

Redundant power
Reduce the chance that power disruptions on a single distribution channel or PDU causes data and service availability degradation.

Maximize service availability
When paired with another identical unit, Synology High Availability enables automatic minute-level failover between two clustered servers in the event of a server failure to minimize service downtime.

Data integrity and protection
ECC memory and the Btrfs file system bring higher reliability and snapshot capabilities to help prevent data corruption and simplify data protection.

High performance storage for anything
Up to 2,315/1,147 MB/s sequential read and write throughput and over 100K/54K random read/write IOPS ensures ample performance for demanding workloads.

With room to grow with you
Easily upgrade the RS1221+/RS1221RP+ to match your usage environment, whether its for performance, faster networking, or higher storage capacity.

• SSD cache Boost read/write IOPS over HDD-only arrays by 16X or more with NVMe or SATA SSD Cache
• 10GbE ready Improve I/O with faster SFP+ or RJ-45 networking
• Storage expansion Expand to 12 drive bays with a RX418 expansion unit

Data protection solutions, built-in

• Maximize data availability
• Protect your entire IT infrastructure

Hyper Backup
A comprehensive backup and recovery solution for added data protection. Create backup destinations locally, on another Synology device, rsync servers, or cloud-based destinations, such as Google Drive, Dropbox, S3-compatible destinations, and Synology C2 Storage, a dedicated backup destination for Synology devices. Deduplication, integrity checks, and incremental transfer technology reduce bandwidth and storage use.

Snapshot Replication
Easily schedule flexible point-in-time backups of shared folders and 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.

Fully certified storage virtualization solutions
Synology iSCSI storage fully supports mainstream virtualization solutions to enhance work efficiency with an easy management interface. VMware vSphere 6 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.

Synology High Availability
Seamless transition between clustered servers in the event of a server failure to minimize the impact on applications.

Virtual Machine Manager
Run various operating systems in isolated sandboxes. Seamlessly clone, store, and migrate virtual machines.

Synology Drive
Instantly access your NAS files across multiple devices whenever you want, wherever you are.

Central Management System
Conveniently manage your fleet of Synology NAS from a centralized console.

Surveillance Station
Complete surveillance solution for recording, monitoring, and management.

Collaboration Suite
Satisfy all team collaboration needs behind the safety of your own private cloud with Synology Office, Calendar, and Chat.
