High Density 12 Gb/s LFF HDD Storage Server
Data storage capacity continues to expand, increasing the need for enterprise class high density storage enclosures. Today’s business environment requires simple, easy ways to grow capacity as well as providing performance and scalability on demand. The Viking Enterprise Solutions (VES) NSS-4602 High Density Storage Enclosure enables 3.5” or 2.5” SAS/SATA hard disk drive (HDD) and solid state disk (SSD) device connections in a mixed environment. Target device communication and management is enabled via standard serial attached SCSI (SAS 3.0) protocol with enclosure services linked via SES firmware. The enclosure can be configured as a JBOD or NAS.

The VES NSS-4602 Storage Enclosure offers best-in-class performance and capacity, space-saving density, “green” energy efficiency and 24×7 high-availability redundancy of key components.

The NSS-4602 fits into an industry standard 19” rack / 1 meter rack. Its flexible configuration allows it to be deployed in a variety of applications.
