Synology® Introduces Versatile RS2421+, RS2421RP+, and RS2821RP+

Synology has launched its new 12-bay RackStation RS2421+ and RS2421RP+, and 16-bay RS2821RP+, built to excel in large-scale infrastructure backup, business-level file serving, and private cloud services.

“The RS2421(RP)+ and RS2821RP+ units are high-performance storage solutions aimed at SMB customers,” said Julien Chen, Product Manager at Synology Inc.

“Abundant storage capacity, upgraded performance, and redundant power make these units perfect as dependable file servers,” Chen said. “They also support essential remote work applications, such as Synology Office, Synology Drive, and Synology Chat — our file sharing and productivity solutions that keep workers connected and company data accessible.”

More than twice as fast

The new RackStation units boast significant performance improvements over their predecessors.1 The RS2421(RP)+ delivers 103% higher random write IOPS and 161% higher read IOPS, while the RS2821(RP)+ delivers 115% higher random write IOPS and 162% higher read IOPS.2

Customize for your business requirements

The RS2421(RP)+ and RS2821P+ can be fitted with a dual-port Synology 10GbE or 25GbE NIC3 to improve network throughput, or with a Synology M.2 adapter card and fast NVMe SSDs to create an SSD cache,4 a cost-effective method to boost random read/write IOPS of hard drive arrays without occupying standard drive bays. The rackmount units support up to 32 GB of DDR4 ECC memory.5 By attaching an RX1217(RP) expansion unit, drive bays can be expanded to 24 bays for the RS2421(RP)+ and 28 for the RS2821RP+. The units are covered by Synology’s 3-year limited warranty.7
