In recent years, the end user's storage needs grow faster, both for capacity or performance, their request is not inferior to high-end users. Growth from the market situation, the growth rate of mid-market significantly larger than the high-end market. The end user needs in the end is what? Through in-depth analysis of user needs in China, NEC found the answer: high-performance, economical, but also high value-added.
Rack-mount disk array controller unit configuration
More optimal performance
With the rapid growth in data volume, and frequent visits, SAN network for data transmission bottlenecks are becoming evident. NEC fiber midrange disk array family, a new member - S2500 the first to break the deadlock in support of 4G interface technology, to generate a performance leap. S2500 S2400 not only have all the advantages, and standard maximum 400MB / s high-speed 4Gbps FC host interface, even connect multiple servers, it can achieve high speed response. As a result of RAID6 technology, S2500 in product reliability and availability are a significant upgrade. Increasing hard disk capacity increases, longer recovery time after failure, while the corrupted hard drive is no different from continuous worse. S2500 S2400 inherited the RAID 6 advanced technology, through the double parity, significantly increased the reliability and availability of storage devices. RAID 6 configuration during the user can use the NEC's unique Dynamic Pool function, easy to change the logical disk capacity. Without prejudice to other business situations, the user can smoothly and efficiently as needed to create logical disks.
In addition, S2500 also features mature NEC Phoenix patented technology, the slow response to the hard disk for temporary isolation, automatic implementation of the hard disk scan, such as scanning results showed that there is no fault or failure to change can be restored, then the return to the original hard disk in RAID , thus greatly reducing the replacement rate of the hard disk. Meanwhile, the use of Phoenix technology can slow the server to minimize the occurrence of the visit.
Expand accessibility
According to NEC-related technician, S2500 is a compact, scalable, powerful midrange storage products. With disk prices lower, SATA disk storage application in more and more common, give the user the most direct benefit is realized tiered storage, reducing the total cost of ownership, improved product performance and low cost. NEC S2500 can be achieved within the same array, FC / SATA disk mix interpolation functions that require uninterrupted business operations and high-performance applications, you can use FC drives; for backup applications, you can choose high-capacity, low price SATA hard disk, enabling different based on the nature of business, in an internal storage device to achieve a different division of labor, to help users reduce the cost of backup and archiving.
In addition, S2500 innovation to the controller and disk expansion units can be integrated to the existing structure of compression 6U double, reduced to 3U, significant savings in product placement space. This highly intensive design will not affect the S2500 disk scalability, the basic controller unit, up to 15 hard drives installed. Cascade in the disk of each matching cabinet unit, can be installed up to 15 hard drives, and allow up to 7 disk cabinet to the cascade. S2500 good scalability, enables users to under the business and growth in demand for easy storage expansion, the maximum expandable to 32.7TB of storage capacity and 8GB cache capacity.
Functional diversity
In addition to inheriting and carrying forward the RAID 6, Dynamic Pool, Phoenix NEC storage products such as the unique superiority, S2500 also has a variety of copy functions, in addition to the basic remote data replication, dynamic data replication, snapshots and other dynamic data replication capabilities also increased the dynamic data replication - the dynamic snapshot link function. Through a variety of data replication function in close collaboration, fully meet the low-cost high-speed backup and backup needs. In security terms, S2500 to set the logical unit of disk access, preventing illegal tampering of data. Through the period of protection and to the logical disk unit to write to set the limit to be protected from any server from the logical disk write operation, to ensure data integrity.
The face of fast growth companies changing needs, S2500 high-performance, cost-effective and high value-added outstanding performance in the midrange storage market unique.
