Aviva ST-306的主动全备份设计是为了满足对存储器高可用性能的要求，它的设计能完全满足任何硬盘、RAID控制器、网路、或电源故障后仍完全可用的要求。

15个热插拔的SAS或SATA2硬盘，每个都接到两个RAID控制器，两个主动RAID控制器之间保持同步，在硬盘、RAID控制器、或控制器上的光纤通道或千兆以太网接口发生故障后，资料都能从人何一个主动RAID控制器传输，达到最高的可用性。

High Availability
FC/iSCSI Storage Array

• 两个主动-主动RAID控制器之间相连并保持缓存同步
• 光纤通道或千兆以太网接口同时并存
• 同时支持block I/O或file I/O
• SATA 端口复用，让两个控制器都可以存取


• Every module is redundant & hot-swappable for high availability
• Cache mirrored & battery backed
• LVM & PIT Snapshot
• Built in File I/O (NAS) functionality
• Multi-Chassis Management console
• Disk Group roaming
• RAID 0,1,10, 5
• Open x86 architecture for smoothly value-added software porting

Very easy to service, upgrade and manage; effectively reduce maintenance overhead Fully passive backplane can be replace on the field without any screwdriver or tool

• Global spare & background rebuild
• Bad sector reconstructing
• Online Array expansion
• Serial console CLI & web GUI management
• 1+1 hot-swappable 600W PSU
• 1+1 hot-swappable fan units per controller
• Battery backed cache for 72 hrs protection
• 15 SAS or SATAII HDD in 3U rack mountable unit
• Max 4GB cache per controller
• Dual 2Gb FC & dual GbE iSCSI for host interfaces
• Scale out by cascading optional expansion JBOD
• LED for controller, heart beat & dirty cache indication
• Write back, Write through or Auto flexible cache policy
• Performance SAS HDD for business-critical applications or cost-effective SATAII HDD for flat-budget projects
• SFF-8088 SAS wide port connector for capacity expansion
