- Saving energy with MAID technology.
- High availability and high reliability with RAID-TM (Triple Mirror).
Features
High Operability
Up to 12 FC ports in just one disk array
D4-30 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.
Simple installation
The installation process of the D Series has been thoroughly reviewed and simplified.
The installation of the D Series can be completed by just a few steps of the setup wizard of NEC Storage Manager.
Centralized management and operation by visualized Web client
Operational status of the system components such as Storages, connected servers, logical disks and physical disks can be visualized.
The type of HDD is selectable according to the purpose of the system
Selectable from high-speed/high-performance SAS disk drive and large-capacity/low-cost SATA disk drive. These 2 types of HDD can be mixed within the same disk enclosure.
SAS disk drive with high performance for main business which is most frequently accessed. SATA disk drive with low cost for backup use. SAS and SATA disk drives can be mixed within the same disk enclosure, so Disk to Disk backup in a single enclosure is available..
New 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.
High 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 availabiltiy.
Saving energy
MAID Technology to reduce the power consumption of disk drives
The larger the scale of system becomes, the more power is consumed and it has an impact on running cost. The D Series adopts MAID (*) technology aiming at saving energy.
By dedicated software control, this system turns off the motor power of unused disk drives This lead to reduce max.30% of the power consumption, compared with the conventional models.
