Up to 900MB/s High Performance
With active-active controllers and LACP/ Trunking, the AccuRAID AR316IR and AR424IR (dual controllers) are capable of delivering up to 900MB/s* and 200K IOPS*, while AR316I and AR424I (single controller) are capable of reaching 450MB/s* or 120K IOPS*.

* Performance varies based system hardware.


Single Upgradeable or Active-Active Redundant Controllers
AccuRAID's innovative design allows customers to start with a single controller, offering quad GbE iSCSI ports, and upgrade to active-active redundant controllers at a later time. AR316IR and AR424IR with dual controllers provide high-availability and robust storage capabilities in enterprise IT environment. Both the AR316I(R) and AR424I(R) offer a peace of mind due to their high quality constructions and redundancy features.


Redundancy Modular Design for High Availability
In addition to hot-swappable redundant controllers, the AccuRAID iSCSI units are also designed with redundant power supplies and cooling fans, providing protection against hardware component failures. With modularized design for easy replacement and service, the AccuRAID iSCSI units provide highly reliable storage for the most demanding IT storage application.


SAS Storage Expansion
Storage expansion via built-in SAS expander supports up to a total of 96 hard drives (192TB in raw capacity) with up to 3 additional JBOD units, providing the best return on investment. With built-in multi-RAID volume support, online expansion and RAID migration, IT administrators could now increase storage capacity without service interruptions or system down time.


Built-in Snapshot and VD Clone

Feature-rich AccuRAID iSCSI units are designed with a snapshot feature without the need for additional software. Snapshot provides a point-in-time copy of the data and allows IT administrators to roll back the snapshot copy to recover previous data. Up to 16 volumes (32 snapshots are supported per volume), total 512 snapshot volumes per system, are supported. The high-performance hardware RAID processor is built-in into the AR316I(R) / AR424I(R), freeing CPU utilization to other task, avoiding performance impact on the host server when such feature is in action.


Based on Snapshot technology, the VD Clone feature allows two virtual disks to create the exact same copy of data, resulting in an additional copy of volume data for security purposes.


iSCSI Applications

iSCSI uses SCSI protocol over Ethernet to provide high-speed block level data transfer. By utilizing Ethernet, iSCSI is not limited by physical location limitations, where the storage unit must be in close proximity to the server or hosting computers utilizing the iSCSI storage service. The AccuRAID iSCSI units provide excellent data transfer throughput via Ethernet and are excellent choices as storage building blocks for high performance SAN (Storage Area Network) due to their high availability, high performance and expansion capabilities.


Clustering consists of two servers using the same volume. With dual controllers, dual network cards and dual network switches, the AR316I(R) / AR424I(R) eliminates single point of failure, acting as a mission critical solution meeting clustering computing requirements.


Virtualization provides benefit such as high availability and disaster recovery. With virtualization softwer, VMware vSphere, Microsoft Hyper-V and Citrix Systems XenServer, AR316I(R) and AR424I(R) provide native iSCSI support for virtualization environment, simplifying the IT environment and increasing the ROI.
