NEC's D-Series SAN Storage arrays provide highly available and easily scalable storage for your SAN without sacrificing performance and flexibility. They include high-end features you won't find on other mid-range arrays, but at a lower cost than other systems. There are four models -
D1 Small to Medium Fibre Channel (up to 72TB FC)
D3i IPSAN (up to 144TB, iSCI attach SAS, SATA, and SASD/SATA intermix)
D3 Large Fibre Channel (up to 144TB, Fibre attach SAS, SATA, and SASD/SATA intermix)
D8 Data Center (up to 1.5 PetaBytes, 4-64 ports, 3-1,536 HDDs}
as well as a complete array management suite for businesses of all sizes that includes snapshots, replication, performance management, multipathing, failover, compliance, energy conservation, and more.
NEC D3i
The D3i array has many built-in features and supports NEC's enterprise-class storage software. A single D3 array can scale from just 219 GB to 144 TB capacity by adding up to eleven 2U 12-drive expansion enclosures.
Aggregate throughput of over 400 MB/s to hosts is provided through up to four 1 Gbps iSCSI Ethernet ports. These can be connected into a network or direct-connected as a simple and low-cost DAS configuration. (A Fibre Channel model is also available.) The disk enclosures are connected to the controllers 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.
