Key Features

Density
The layout and chassis design provides four nodes in 2U and up to 84 Nodes in a 42U standard rack which is perfect to save rack space. The four full servers in a 2U chassis are backed up with high efficiency redundant hot-swap power supplies

Performance
With the ability to use the latest in processor technology from the AMD 6200 series CPU, Viglen is able to deliver unsurpassed memory I/O and performance

Cost Reduction
The Viglen 2U HX425T2a reduces TCO and running costs by not only saving rack space but also by incorporating a 90%+ efficient PSU. Having a more efficient power supply means a lower overall power draw which leads to lower electricity and air-conditioning bills.
