QSAN XCubeDAS

The XCubeDAS (XD5300 series) is QSAN's fully redundant JBOD expansion enclosure system, and it's the secret weapon for organisations that need to scale storage capacity without replacing their existing infrastructure. These aren't your basic drive shelves — they feature active-active dual controllers with cable-less, fully modularised hardware and 12Gb/s SAS 3.0 wide ports for massive bandwidth.

Performance numbers are genuinely impressive: up to 24,000 MB/s sequential read throughput and over 4.2 million IOPS by distributing I/O loads through multiple paths. That means your expansion enclosures won't become the bottleneck when you add capacity — a common problem with cheaper JBOD units from other vendors.

The XCubeDAS works as a JBOD expansion for QSAN's own XCubeSAN, XCubeNXT, and XCubeFAS arrays, but it also plays nicely with Windows Storage Spaces and any server equipped with SAS HBAs. If you're doing HPC, building cloud storage pools, or running bandwidth-hungry 4K/8K video workflows, the XCubeDAS gives you the raw capacity and throughput to keep up.
