Ultra-Dense, Cost-effective SAS/SATA JBOD Expansion
The DataON DNS-1660 Ultra-Dense 6 Gb/s SAS/SATA JBOD solution enables massive data capacity applications, at a price/performance point per Gigabyte (GB) that meets your fast-moving business requirements. Besides functioning as a standalone external direct attached storage (DAS) JBOD for standard serial attached SCSI (SAS) host connect, With up to 60 3.5” form factor SAS and/or SATA Hard Disk Drives (HDDs) per 4U enclosure, the industry-unique DNS-1660 is an ultra-dense, space and power savings solution.
The DataON DNS-1660 fits nicely into a standard 19” wide, 1m long, 42U rack that easily creates a 30TB/U (w/ 2TB SATA HDDs) data expansion building block that can be zoned to up to four different DAS Hosts. Additional DNS-1660 JBODs can be daisy chained to support deeper storage pools as supported by industry standard SAS HBAs and SAS RAID HBAs
|
Host/expansion Interfaces
- One or two SAS JBOD I/O controller modules per system, with each I/O module supporting four 6Gb/sec SAS SFF-8088 connections
- 6Gb/sec SAS SFF-8088 connections can be used for host connections or as a combination of host connection and expansion and support up to 2,400 MB/sec bandwidth
- Daisy chaining of enclosures for overall number of drives will most likely be limited by the specific qualified SAS HBA or SAS RAID HBA used in the configuration
Capacity
