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.

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.

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, enabling up to 12Gbps in transfer speeds.

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

DynamicPool

Traditionally, logical disks could only be managed in units of the physical sets of disks that made up the RAID, users had to install a fixed number of disks even if they were not necessary. The new dynamic pool function permits logical disk capacities to be changed dynamically. Physical disks can be added one at a time. The logical disks required can be managed efficiently, and the system is free from physical restrictions.

Phoenix Technology for Advanced Preventative Maintenance

Using Phoenix Technology, a disk drive causing a delay in response can be separated from the RAID pool, and a background diagnosis automatically performed. If no defects are found, the drive can be returned to the original RAID configuration without the need for switching to a hot spare disk. Phoenix technology can reduce the need to do rebuilds by up to 50%.

Flexible Equipment Configuration and High Scalability

Flexible hard disk drive options are offered to meet a wide variety of needs:

In addition, the D1-10 Storage Array has dual controllers, supports SATA 750GB drives and can be intermixed with high performance SAS drives within the same array or device enclosure. RAID-1, RAID-5, RAID-10, RAID-50, and RAID-6 can be installed in mixed configurations. Four host FC ports are built-in as a standard. A maximum of 7additional disk enclosures, each capable of mounting 12 disk drives can be connected to equate to 96 HDD. The D1-10 Storage Array can support 1 GB of cache per controller.
