NEC D1-10 Entry level SAN/DAS Storage
OverviewNEC'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
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 5 optional disk enclosures can be connected to the D1-10, providing a maximum capacity of 54TB 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 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, enabling up to 12Gbps in transfer speeds.
FeaturesHigh availability, high reliability
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.  Saving energy
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. 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:
SoftwareStorageManager
StorageManager is the integrated storage software package that provides basic control to NEC's D1-10 Storage Array. This software features GUI display for the configuration, monitoring, error reporting, and performance information on logical disks and controllers.
AccessControl (optional)
Access to the logical disks can be set for individual ports or hosts (LUN masking).
PerformanceMonitor (optional)
Includes real-time status of information on the array's performance, load monitoring, and statistical analysis.
ReplicationSuite (DDR+DSV) (optional)
DDR or Dynamic Data Replication provides for full copies of LUNs. Generally these copies are fractured and re-assigned to other connected hosts for such needs as batch processing, testing with production data, or even parallel backup. DSV or Dynamic Snap Volume provides for a copy of the changed data between two points in time (PIT). This technology facilitates advanced recovery of data from up to 16 earlier states without the need to locate and search through traditional tape medium. Since only the changed data is written, cost savings is realized over the full copy methodology
