High Performance Enterprise Class High Density 94 drive Storage Server
The Viking Enterprise Solutions (VES) NDS-4900 High Density Storage Server combines 90 3.5” hard disk drives (HDD) with four 2.5” solid state disks (SSD) at 12Gb/s. There is no need to sacrifice HDD slots to incorporate SSDs for caching.

The enclosure contains either two single or two dual processor Haswell/Broadwell servers. Each server can power 2x 145W processors and 2x full spec PCIe cards. The servers are specifically designed for data throughput. The VES NDS-4900 Storage Server offers best-in-class performance and capacity, space-saving density, “green” energy efficiency and 24×7 high-availability redundancy of key components.

The NDS-4900 fits into an industry standard 19” wide by 1.2m deep rack. Its flexible configuration allows it to be deployed in a variety of applications.
