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