DNS 1640 is a high-availability, cost-effective
2U SAS (Serial Attached SCSI) to SAS (Serial
Attached SCSI) JBOD, which provides 24 pcs
2.5” hard drive carriers to support various
types of hard drive, including 6Gb/s SAS hard
drive, and 6Gb/s SATA III hard drive with in-
terposer card. In addition to 24 pcs hard drive
carriers, DNS-1640 system supports two 550W
Full Redundant Power Supplies and two SIM
modules.
High Reliability: Redundant SIM modules,
power supplies modules design secure “No
Single-Point Failure”. Active-Active Dual
6Gb/s SAS I/O Module Architecture, hot-
swappable hard disk, and dual SAS and SATA
II paths with Interposer Card ensure that DNS-
1640 has high reliability and achieves 24x7
availability.
High Scalability: Each DNS-1640 system sup-
ports a maximum of 24 6Gb/s SAS/SATAIII
hard disks per system, and up to 96 drives by
daisy-chaining JBOD.
High Flexibility: DNS-1640 system supports
both SAS and SATA disks depending on cus-
tomer’s needs. This feature provides the most
cost-effective storage pools for different kinds
of data and provides a better management
for ILM (Information Life Cycle Management)
applications.
High Performance: The Active-Active Dual
6Gb/s SAS I/O Module Architecture ensures
