The AccuRAID AR442F8R series is a high density 4U rackmount designed for storage hungry applications, and accommodates up to 126TB of storage space. The unit utilizes advanced Fibre technology when operating as direct attached storage (DAS), and could be setup as a storage area network (SAN) with the assistance of a Fibre Channel network switch. In addition, the quad Fibre Channel ports allow the support of clustering, where the unit could be accessed by multiple servers, ensuring continuous uptime in a production environment.
To reinforce the AR442F8R’s ability to overcome hardware failure, two redundant and hot-swappable power supplies and cooling fans are available for added safeguard. Active-Active redundant controllers allows further failure protection when needed. Internally, the AR442F8R supports up to RAID 60, with RAID monitoring, RAID notification, automatic failover, and automatic recovery. Build-in expansion port allow up to two additional JBOD unit (AS424X6R) with up to 126 bays or 378TB. The unit’s built-in Ethernet port with web based management console and SES management features provide instant access to the status of the RAID array and the enclosure to reduce downtime. SAS drives is supported, while SATA can be used with additional mux board.
Note: Sans Digital recommends the use of enterprise hard drives when in use with any RAID controller applications. Standard desktop or green desktop drive may not be supported and may compromise RAID system stability and performance. For more information on the difference between RAID and desktop hard drives, please see the Western Digital knowledge base.
