NEC D3-10 Storage Array

NEC's D3-10 Storage Array is a mid-range model positioned for the medium sized business providing additional capacity, IOPS, and throughput to handle a greater number of hosts and larger storage requirements. Additional support for mixed SAS/SATA configuration meets the demands of differing quality of service requirements. The D3-10 supports four high speed 4Gbps host connections and high performance RAID processors.

As your business needs grow, the D3-10 meets the demand with up to an additional 11 disk enclosures which can be connected to provide a maximum of 108TB with 144 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.

D3-10 is disk array with up to 144 HDD
* Having up to 144 SAS or SATA HDD modules, the maximum capacity is 85.0TB.
* Up to 12 FC ports can be supported.
* 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 RAID-TM (Triple Mirror).

Features

High Connectivity Up to 12 FC ports in just one disk array
D3-10 can have up to 12 FC ports, so that up to 12 servers, up to 6 servers when the path has redundancy, can be connected without FC switch. This reduces space and TCO.

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

RAID Engine
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 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 6 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. Up to 12 host connections are available.

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 D3-10 Storage Array contains an NEC 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. Replace below storage system with new graphics. or leave out

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.

StorageManager
StorageManager is the integrated storage software package that provides basic control to NEC's D3-10 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.

Remote Data Replication (optional)
Replicates business volumes defined for each logical disk, enabling use of replicated data at a remote site.
