iSCSI-SAS 4U 24-bay High Availability RAID Storage



  • Four iSCSI ports per controller
  • Up to 200K IOPS & 900MB/s throughput
  • Fully redundant hot pluggable designs RAID controllers, power supplies, fan modules, battery backup modules, JBOD expansion
  • Hardware iSCSI offloaded engine
  • Disk spin down, advanced cooling,  80 PLUS energy-efficient power supplies
  • Advanced data protection: RAID 6, 60, QSnap writeable snapshot, Windows VSS support
  • Flexible volume management for multiple applications and environments: virtualization (VMWare, Hyper-V, Citrix), cloud storage, SQL, Exchange, CCTV, file backup, email, boot from SAN etc.
  • High connection availability: load balancing, failover
  • Extendable capacity up to 144TB


The P400Q's powerful RAID controllers provide much higher IOPS and throughput than other storage systems within the same segment in the current market. The P400Q can minimize your cost and optimize your investment, simplify storage planning, and integrate more applications.


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 iSCSI interface, P400Q is ideal for virtualization environments - VMWare, Hyper-V, and Citrix. Users can install up to 128 OSes in the iSCSI 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

P400Q iSCSI system is specially designed for high availability applications. The P400Q has fully redundant components including redundant RAID controllers, power supplies, fan modules, battery backup modules and SAS JBOD expansion ports. All of these components are hot-swappable to create a high availability platform and provide non-stop services. Special features in firmware are RAID 6, 60 support, QSnap writable snapshot, Windows VSS support, volume cloning, QReplica remote replication, and volume configuration restoration. All these features are designed to add an extra layer of protection to your valuable data. To raise the bar higher, P400Q can 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 disconnected, the other RAID controller will take over all tasks immediately and seamlessly.


All P400Q system has Qsan’s default power saving feature. 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. P400Q 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, we can use energy more efficiently and reduce unnecessary carbon footprint.
