StorageReview.com Review:

XS1200 Review (Base Model)
"It certainly is one of the fastest SQL Server storage arrays we have seen so far..."

"Overall the QSAN XCubeSAN XS1200 has a lot of great capabilities to help it make a name for itself in the market. At entry-level midmarket pricing, it outpaced many of the systems we've tested in much higher price brackets."

XS5226D Review
"Overall, the XS5200 did quite well, taking full advantage of the Toshiba PX04 SAS3 SSDs we installed. Performance in total is very impressive, as 6GB/s read and 5GB/s write (64K sequential) out of an SMB SAN is very good."

Wide Ranging Product Portfolio

XCubeSAN models come in multiple configurations to fit your needs and budget. For many the XS1200D system with dual controllers would be the sweet spot. However if you are limited by budget, you can start with the single controller XS1200S and add a second controller later. For applications that serve a larger-than-typical client load, the XS5200 model provides double the CPU power and memory. For even better caching performance memory upgrades are available - up to a maximum of 32GB per controller for XS1200 and 128GB per controller for XS5200 series.

Built-in High Speed 10GbE LAN Ports

Each controller includes two 10gbE ports, and with 40gbps throughput on a dual controller system, the base unit is ready for a variety of applications including data sharing, backup, video editing, and native virtualization support for VMware, Citrix, and Hyper-V.

Scale-up Solution

A unique feature of XCubeSAN is the expansion system. Need more ports? More bandwidth? Fibre Channel? Don't have a 10gbE or FC switch/network in place? No problem! XCubeSAN allows you to expand up to 12 FC or 20 10gbE or 16 1gbE ports!


Custom designed SAN OS 4.0 is designed for ease of use and full of speed, reliability and convenience features such as snapshots, thin provisioning, local volume cloning, automatic SAN to SAN replication, SSD caching, auto-tiering. Full support is provided for VSS, MPIO, MC/S, VSS, ODX and VAII. SANOS supports complete RAID levels including RAID 0, 1, 0+1, 3, 5, 6, 10, 30, 50, 60, N-way mirror, and also RAID EE technology including RAID 5EE, 6EE, 50EE, 60EE for reducing the long rebuild risk. You can choose the appropriate RAID level to best suit the application requirements.


No SAN unit is complete without a high-quality support system. While QSAN Technology is primarily Taiwan-based, they are available during part of US business hours. To bridge the gap, PC PitStop, as well as other QSAN partners in the US, provide first line of support, carry spare parts and assist with any warranty issues.
