NEC D1-10 Storage Array

NEC's D1-10 Storage Array is an entry-level model that offers excellent performance and TCO, including support for a mixed SAS/SATA configuration that meets the demands of differing quality of service requirements. The D1-10 supports four high speed 4Gbps host connections, high-performance RAID processors and up to 72 disk drives.

A disk array for customers with smaller storage requirements, NEC's D1-10 Storage Array has a standard 2U EIA cabinet with the capacity for 12 disk drives. An additional 7 optional disk enclosures can be connected to the D1-10, providing a maximum capacity of 72TB with 72 disk drives. RAID-6 technology is included to ensure continued operation even if errors occur in two hard disks at the same time. This technology greatly enhances the availability of the disk array and can be used together with other storage pools such as RAID-1 and RAID-5.

D1-10 is Entry model disk array device with up to 72 HDD modules

* Having up to 72 SAS or SATA HDD modules, the maximum capacity is 42.5TB.
* Host interface is FC 1Gbps, 2Gbps, or 4Gbps
* High operability with setup wizard which reduces installation time, visualized configuration and mixed use of SAS/SATA HDD.
* High performance with new RAID engine and SAS Wide Link.
* Saving energy with MAID technology.
* High availability and high reliability with (Triple Mirror).

High Performance RAID Processors
Performance is enhanced with new RAID engine which has high internal transfer speed. The load of the processor can be offloaded to the RAID engine.

Centralized management and operation by visualized Web client
The D Series offers GUI of Web client for every operation from installation to administration.

Operational status of the system components such as Storages, connected servers, logical disks and physical disks can be visualized.

SAS technology is leveraged
SAS (Serial Attached SCSI) has been adopted for the disk array. "Wide Link" technology of SAS can use 4 sets of 3Gbps SAS interface in parallel, so that it realizes 12Gbps transfer speed.

RAID-TM (Triple Mirror) with more advanced high availability
RAID-Triple Mirror by high-speed RAID engine is adopted. This technology has high speed of RAID-1 and high reliability of RAID-6 at the same time. The business can continue even when double failure occurs to the HDDs of the same RAID. This technology is useful especially for Database and OLTP which require high performance and availability.

MAID Technology to reduce the power consumption of disk drives
The D Series incorporates MAID technology. This technology allows customers to save power by allowing disks to be powered off.

Standard Four FC Host Ports, Four Gbps Each
Up to two servers with dual paths can be connected without an FC switch, enabling a simple and low-cost configuration. For larger configurations, one to two fabric switches are installed between the storage device and host systems.

Component Redundancy
Redundancy with field-replaceable, hot-swapping is provided for all major components such as controllers, cache memory, power supplies, battery backup units, and fans - insuring business up-time even in the rare event of a component failure.

RAID-6 Technology
RAID-6 technology ensures continued operation even if errors occur in two hard drives at the same time. RAID-6 greatly enhances the availability of the disk array, and can be used together with RAID-1 and RAID-5 storage pools. RAID-6 records two parity values, P and Q, which are generated by two independent equations made from the data. NEC's D1-10 Storage Array contains a ASIC LSI RAID processor, which carries out the complex RAID operations. RAID-6 provides high performance and keeps the device highly reliable.
