P500Q 10GbE iSCSI system is specially designed for high availability applications. The P500Q 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, and volume configuration restoration; all of these are provided to reduce the chance of rebooting or shutdown. Distinct from others, P500Q 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. P500Q IOPS is 220,000 at maximum, much higher than other storage systems within the same segment in the current market; besides, its throughput is 1300MB/Sec. at maximum. 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 10GbE iSCSI interface, P500Q is ideal for virtualization environments - VMWare, Hyper-V, and Citrix. Users can install up to 32 OSes in the 10GbE 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. All P500Q 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. P500Q 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.  | P500Q-D424 | P500Q-S424 | | Hardware Components | | RAID Controller | Dual controllers | Single & upgradable controller | No. of Host Channels
