The D3 array has many built-in features and supports NEC’s enterprise-class storage software. A single D3 array can scale from just 300 GB to 288 TB capacity by adding up to eleven 2U 12-drive expansion enclosures.
Aggregate throughput of over 1,100 MB/s to hosts is provided through up to twelve 4 Gbps Fibre Channel ports. These can be connected into a switched fabric SAN or direct-connected as a simple and low-cost DAS configuration. (An iSCSI model is also available.) The disk enclosures are connected to the controller via SAS wide-link connection for 24 Gbps bandwidth to each disk enclosure.
The system is fully redundant to protect against single-point-of-failure, with a battery backup unit for protecting the cache. Failed components are reported via alerts by either email or SNMP traps and in the management software.
