12-bay 2U rackmount NAS
The Synology RS2421RP+ is a 12-bay 2U rackmount NAS powered by an AMD Ryzen V1500B quad-core 2.2 GHz processor with 4 GB DDR4 memory expandable to 32 GB. It provides high read/write performance with RAID for small business and remote office file management, sharing and backup. Redundant power supplies are included. Drives are not included.
Installation and common issues
Mount the 2U chassis in a standard rack and populate up to twelve 3.5" or 2.5" SATA drives in the hot-swap bays. The single PCI Express 3.0 x8 slot accepts compatible expansion cards for SSD cache or faster networking. Only Synology SAT5200 2.5" or SNV3400/3500 M.2 SSDs sold separately can be used for SSD cache; other M.2 drives will not function in that role.
Pre-order checklist
Verify rack depth and clearance for the 22.76" x 18.98" x 3.46" chassis and 26.24 lbs weight. Confirm the operating environment stays within 0°C to 35°C and 5% to 95% RH. Ensure network infrastructure supports the four 10/100/1000M RJ-45 ports and plan for any 10/25GbE upgrade via the PCIe slot. Check that required drives are on the Synology compatibility list.

Questions about this item
How can I confirm the RS2421RP+ is operating correctly after rack installation?
Watch the front-panel LEDs: the power indicator should stay solid, the status light should turn green after boot, and all twelve drive-status LEDs should show steady or blinking green once drives are seated and volumes are mounted.
What ships with the RS2421RP+ and which drives or cache SSDs must I purchase separately?
The box contains the 2U chassis with redundant power supplies, four RJ-45 ports, two USB 3.2 Gen 1 ports, one PCIe 3.0 x8 slot and 4 GB DDR4 installed; you must supply twelve 3.5″ or 2.5″ SATA drives, and only Synology SAT5200 2.5″ SSDs or SNV3400/3500 M.2 SSDs are validated for SSD cache.
Which memory configuration should I choose for the RS2421RP+ given the 4 GB base and 32 GB maximum?
Start with the factory 4 GB DDR4 module; add matched DDR4 DIMMs up to 32 GB total if you run virtual machines, many Docker containers or heavy multi-user file workloads.
