High Availability
D1-QIG iSCSI system is specially designed for high availability applications. The D1-QIG 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, Opslag 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,D1-QIG 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.
Outstanding Performance
D1-QIG IOPS is 200,000 at maximum, much higher than other storage systems within the same segment in the current market; besides, its throughput is 900MB/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 iSCSI interface, D1-QIG is ideal for virtualization environments - VMWare, Hyper-V, and Citrix. Users can install up to 32 OSec in the iSCSI system through the Boot-from-SAN feature.With this feature, the multiple OSec/Servers can be managed easily and well protected by OPSLAG’s advanced data protection features, and there will be no system down time caused by single point of failure.
All D1-QIG systems are equipped with Opslag’s default green features for power saving. In most cases, the hard drives consume most power. With the autodisk spin down feature and proper configuration, the power consumption ofhard drives can be reduced to a minimum, and users will not even notice this feature. D1-QIG 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.
