The Perfect RAID Expansion Enclosure for QSAN Storage
QSAN XCubeDAS 5300 series is a cost-effective DAS (Direct Attached Storage) or JBOD (Just a Bunch Of Disks) for server expansion. It is also a RAID expansion enclosure for QSAN storage.
XD5300 Series Models
Flexible Expansion
Scale Up Your Storage
The XD5300 series expansion enclosures offer flexible drive configurations. For LFF chassis of XD5324/XD5316/XD5312 models, they support mix and match 3.5"/2.5" SAS, NL-SAS HDD, and 2.5” SAS, SATA SSD. For SFF chassis of XD5326 models, they support 2.5" SAS, NL-SAS HDD, and 2.5” SAS, SATA SSD.
For the maximum number of disk drives support, it depends on the capability of the HBAs and RAID controller cards.
To provide a fault-tolerance and load-balancing storage system, all data paths in the system from hard drives, backplane, expander physical links, and front-end ports to servers have to be both hardware and well-defined firmware redundancy protection. The XCubeDAS 5300 series is built with fully redundant paths and protection to every data I/O and compatible with Microsoft Windows MPIO, Clustering, and Linux Multipathing. The multipath software layers in the operating systems can leverage the redundant paths to provide performance enhancing, e.g., load-balancing, round-robin, failover, and dynamic reconfiguration.
Zoning
Like Using Multiple in One Box
Users can select a specific group of disk slots and define a zone for it. There can be up to 5 zones per system. Each zone can be assigned to at least 1 x 12Gb/s SAS port. The zoning feature provides better security control even in the direct-attached system scenario. Users can use different zones for multiple host servers that connect to the same DAS systems and still have different access control for different zones.
Versatile Topologies
Adapt Various Connections Freely
The XD5300 features all 12Gb/s SAS topologies and permutations of all host and expansion port configurations. The XD5300 series supports all 12Gb/s SAS topologies, including Cascade, Reverse, and Tree. The XD5300 series can be deployed freely to fit various connections to the host servers. With up to 10 x 12Gb/s SAS ports support per system, this feature is crucial for users to plan a well-defined resource arrangement to achieve highly utilized performance and capacity of the XD5300 system.
Cascade
The cascade connection is a daisy-chain topology that connects each device in series to the next.
Reverse
One path is a cascade topology; the other is a reverse cascade to prevent a single point of failure.
Tree
The tree topology will shorten the connection path to achieve balanced performance.
Runtime Configuration
Automatic Detection without Setting
The XD5300 controller’s host and expansion ports can be configured and changed IN / OUT5 during runtime for different applications and environment requirements. The setting is effective immediately without rebooting the system. The 5 IN, 4 IN / 1 OUT, or 3 IN / 2 OUT configurations displayed below are recommended for better performance utilization.
