24-bay 2.5" SAS/SATA expansion unit
The Synology FX2421 is a 2U rackmount expansion unit that adds 24 additional 2.5-inch drive bays to a compatible Synology FlashStation. It connects via the supplied high-speed expansion cable using SAS IN and SAS OUT ports for online volume expansion without downtime. Drives are not included and the unit supports SAS SSDs, SAS HDDs and SATA SSDs for flexible deployment.
Suits FlashStation owners needing dense capacity
Organisations that already run a Synology FlashStation and require immediate, high-density storage growth will benefit from the 24 hot-swappable bays and seamless expansion. Buyers without a compatible FlashStation cannot use this unit as a standalone NAS and should look at a complete rackmount system instead.
SAS expansion connectivity decides fit
The single specification that determines compatibility is the SAS expansion interface: the FX2421 must be cabled to a FlashStation that provides a matching SAS expansion port, so verify that your existing FlashStation model supports SAS-based capacity expansion before purchase.
