AegisSAN Q500

High reliability storage systems optimized for throughput and designed for SMB.

Optimized Throughput

AegisSAN Q500 series are optimized for demanding high-throughput applications. It can deliver more than 6,000MB/s for throughput requirements.


Energy Efficiency

AegisSAN Q500 series adopt power efficient CPU, 80+ Gold PSU, smart enclosure management firmware, and disk auto spindown technologies for more than 60% power saving.

Enterprise Data Protections

Snapshot | Clone | Replication

QSAN array built-in data protection features protect your data under any circumstances without extra charge and without performance impact.


QSAN Data Protection Solution Advantages:

  • Multipath and failover
  • Instant rollback when virus attacks or accident deletes
  • Reduce the impact risks of disk failures
  • Protect data against disasters
  • Increase application availability
  • Automatic data synchronization to avoid traffic jam
  • Flexible configurations for various storage plans

Smart Data Management

SSD Caching | Fast Rebuild
Thin Provisioning | Seamless Roaming | Copy Migration

When the original storage planning or configuration doesn’t fit anymore, QSAN smart data management features can recover the status back to normal quickly and minimise the system risk.

SSD Caching

QSAN SSD caching leverages the strengths of both SSDs and SAS/SATA hard drives to cost-effectively meet both high speed and large capacity requirements. It accelerates application performance by utilizing SSD drive as extended RAID controller cache for hot data while most of the cold data are stored in the hard drives.

Performance improvement is up to x 18 times.

Fast Rebuild

QSAN Fast Rebuild only rebuilds the partitions with data. With embedded hardware RAID engine, it can greatly reduce the system loading, minimize the performance impact, and reduce rebuilding time as well.


Thin Provisioning

The Thin provisioning feature provides efficient use of total available capacity, centralized management, data protection, flexible storage planning, and automatic extension when allocated space runs out.

QiSOE 2.0: QSAN Hardware Offload Engine

AegisSAN LX series adopts a dedicated CPU core to process iSCSI and Fibre Channel packets. From our lab result, both iSCSI and Fibre Channel storage systems have significant performance improvement.

iSCSI write throughput x1.5 times faster                    FC IOPS performance x1.6 times faster
