High Availability

The dual active controllers plus fully redundant and hot-swappable designs make AegisSAN Q500 series system a highly available system. It offers multiple paths and load balancing features such as MPIO, MC/S, Trunking, and LACP to better ensure the reliability.

Enhanced Data Security

The innovated USB LCM allows AegisSAN Q500 storage to avoid data leakage in data centers, lower TCO and enhance the manageability for IT administrators. This series includes QSnap for writeable snapshot and QReplica for remote replication to maximize customers’ return on investment. The battery backup module keeps cache data safe in the event of power outage.

Great Performance & Efficiency

The proprietary QiSOE (Qsan hardware iSCSI offload engine) boosts the performance for the disk array. The outstanding designs of the controllers make AegisSAN Q500 series system provide great IOPS and throughput for performance demanding applications. The hardware RAID makes the reliability better and volume robust.

The ultra high density storage system features QThin, the thin provisioning function to provide more physical resources than actually available capacity so that IT administrators can avoid allocated but unused storage and purchase only the disk capacity they actually need to significantly raise storage utilization and to save cost.

AegisSAN Q500 series supports VMware vSphere 5 VAAI (vStorage APIs for Array Integration), Citrix and Hyper-V for highly virtualized environments. With VAAI certification, the disk array can offload server and network loading, speed up provisioning of new virtual machines and increase VM density.

Software Value Add-ons

AegisSAN Q500 series system offers top-notch functions including QSnap (copy-on-write snapshot), volume cloning, QReplica (remote replication), Windows VSS, N-way mirror and so on for well-rounded data protection.


Green Designs

AegisSAN Q500 disk array adopts Intel’s latest S1200 series CPU and it’s the SAN solution with outstanding energy efficiency and cost effectiveness. This platform includes key features such as error code correction, 64-bit support and virtualization technologies.

In addition, AegisSAN Q500 system is equipped with 80 Plus Gold power supplies to achieve 90% energy efficiency as well as peak reduction and improved power quality.

The auto disk spin down function enables the system to reduce power consumption of hard drives which account for the most electricity in the storage system.



Deliver the Best Price-Performance Value for Budget-constrained Enterprise & SMB

QiSOE (Qsan Hardware iSCSI Offload Engine)

AegisSAN Q500 iSCSI series system features QiSOE (Qsan hardware iSCSI offload engine), which adopts a dedicated CPU core to process iSCSI packet. With QiSOE the performance will be booming up dramatically.

Thin Provisioning

AegisSAN Q500 series delivers thin provisioning to provide more physical resources than actually available capacity so that organizations can avoid allocated but unused storage and be able to purchase only the disk capacity they actually need. Therefore, thin provisioning feature can significantly raise storage utilization and help enterprises to save cost.


Disaster Recovery: QSnap & QReplica

Data protection and backup solutions play an important role in storage systems. QSnap the snapshot feature is a very cost-efficient application to protect valuable business data. A snapshot primarily creates a point-in-time copy of the data and with Qsan’s “copy-on-write” technique QSnap only copies the changed data instead of copying whole data so as to be highly space efficient. QReplica is the remote replication tool that deploy full data copies across storage systems at different sites through LAN or WAN. In addition, QReplica supports to replica multiple logical volumes in one system at one time

product-Q500-P21-1Virtualisation Technologies

Virtualisation refers to the creation of a virtual machine that acts like a real computer with an operating system. It adds a new layer of software and hardware between storage systems and servers so that applications no longer need to know on which specific drives, partitions or storage systems their data resides. This greatly enhances the flexibility, agility, scalability and manageability. AegisSAN Q500 storage system supports virtualisation technologies of VMware, Citrix and Hyper-V enabling improved performance, superior scalability and better agility in the highly virtualised working environments.

Hardware Redundancy

Qsan storage systems are equipped with fully redundant components for all major functions, including dual active RAID controllers, power supplies, fan modules, battery backup modules, and SAS JBOD expansion ports. Being hot swappable, all of them enable non-stop services for enterprises.
