Quantum QXS Maintenance — vendor-independent service for block storage
We service Quantum QXS Block Storage after reaching EOSL — for fleets from the Dot-Hill acquisition era running technically clean but no longer getting Quantum renewal. QXS-312, QXS-412, QXS-424, QXS-424-D, QXS-484 with OEM disks and controller boards from our own warehouse. Up to 70 percent below former Quantum list price.
Which QXS models we service
QXS is Quantum's block storage line from the Dot-Hill acquisition in 2015. Five model classes: QXS-312 (12-bay 2.5" entry), QXS-412 (12-bay 3.5" entry), QXS-424 (24-bay 2.5" mid-range), QXS-424-D (deep archive variant), QXS-484 (84-bay high capacity). The platform is technically related to the HPE StorageWorks-MSA family because both are based on the common Dot-Hill OEM design.
Why TPM maintenance is the only path for QXS
QXS is now a Quantum niche. After the Dot-Hill acquisition in 2015, Quantum consolidated its focus on backup, archive and workflow — block storage as a category is no longer strategic. Result: QXS renewals are no longer available in most configurations, or only at rates designed to economically force a refresh. For DACH QXS fleets — typically mid-market IT sites with small block storage needs — TPM is the only economic path.
We service QXS with OEM SAS and NL-SAS disks of all sizes, controller boards and FC/iSCSI connectivity. Advantage: QXS is technically very similar to the HPE StorageWorks-MSA family (common Dot-Hill OEM design) — many components have high availability. For very rare QXS-specific components we work with certified refurbishing partners.
Generations timeline & TPM coverage

EOSL status of QXS platforms
QXS from the Dot-Hill era (acquired 2015) has largely reached EOSL. Quantum has not actively developed the line — refresh recommendations typically lead away from QXS toward third parties or ActiveScale Object.
