F400Q-D424 / F400Q-S424

4Gb FC-SAS 4U 24-bay High Availability RAID Storage



  • Two 4Gb FC ports per controller
  • One iSCSI port per controller
  • Fully redundant & hot pluggable designs: RAID controllers, power supplies, fan modules, battery backup modules, & JBOD expansion
  • Green storage designs: auto disk spin down, advanced cooling mechanism, & 80 PLUS energy-efficient power supplies
  • Advanced data protection: RAID 6, 60, QSnap writeable snapshot, Windows VSS support, QReplica remote replication
  • Flexible volume management for multiple applications & environments: virtualization (VMWare, Hyper-V, Citrix), cloud storage, SQL, Exchange, surveillance, file backup, email, boot from SAN, & etc.
  • High connection availability: load balancing & failover
  • Extendable capacity up to 144TB


The F400Q IOPS and throughput are much higher than other storage systems within the same segment in the current market.


The optimized IOPS and throughput are capable of providing run-time critical online services, such as Cloud storage, SQL, Exchange, and high-end surveillance storages. Furthermore, with the 4Gb FC and GbE iSCSI interfaces, the F400Q is ideal for virtualization environments - VMWare, Hyper-V, and Citrix. Users can install up to 32 OSes in the multiprotocol system through the Boot-from-SAN feature. With this feature, the multiple OSes/Servers can be managed easily and well protected by Qsan’s advanced data protection features, and there will be no system downtime caused by single point of failure.

High Availability

The F400Q multiprotocol system is specially designed for high availability applications and featured with Fibre Channel and iSCSI ports in each controller. The iSCSI ports can be activated for Qsan’s system built-in remote replication function – QReplica or used for widely approved iSCSI functions. The unique multiprotocol feature allows users to integrate the applications and data from the FC and IP networks in the same F400Q storage system without extra infrastructure cost. The F400Q is well equipped with fully redundant components for all major functions, including redundant RAID controllers, power supplies, fan modules, battery backup modules, and SAS JBOD expansion ports. Being hot pluggable, all of them provide non-stop services. In addition, the firmware is high available as well, including RAID 6, 60 support, QSnap writable snapshot, Windows VSS support, QReplica remote replication, and volume configuration restoration; all of these are provided to reduce the chance of rebooting or shutdown. Distinct from others, the F400Q is able to upgrade firmware without system down time. Both firmware image and volume handling are well protected by the redundant RAID controllers; when one RAID controller is down or has lost the connection, the other RAID controller takes over its tasks immediately. The volumes and the services are transferred seamlessly simultaneously.


All F400Q systems are equipped with Qsan’s default green features for power saving. In most cases, the hard drives consume most power. With the auto disk spin down feature and proper configuration, the power consumption of hard drives can be reduced to a minimum, and users will not even notice this feature. The F400Q monitors the environment temperature for cooling mechanism and the fan modules respond accordingly. The power supply modules are all 80 PLUS power efficient for better power converting rate. In virtue of the reduction of hard drive power consumption, the advanced cooling mechanism, and the energy-efficient power supplies, the unnecessary power cost is decreased greatly.
