HDslim 4U Rugged High Density Modular Server

Optimized High Density Storage

The HDslim can deliver up to 480TB of storage with 24 direct attached HDD/SSD drives and accommodates existing and upcoming rear I/O RES-HD modules. With double the compute density, it enables a 50% savings in rack space and reduces system weight by 50%.

Minimum Size, Weight, and Power (SWaP)

Only 9.9” (25.1cm) wide, 20” (52.6 cm) deep, and 4RU high (17.5 cm) high, the HDslim is small enough to fit in commercial airline bins. Typically weighing 40lbs with four modules, the system can be carried aboard commercial airliners, aircrafts, and vehicles with ease. Power options include two 1200W AC, two 1100W 48V DC, or two 800W 28V DC power supplies.

Modular Composable Configuration

Simplify Maintenance, Streamline Deployment

With over six processor, storage, high-speed switch, global fabric extension, and system management modules, operators can configure and reconfigure the HDslim according to application needs. Rather than removing and opening up the entire server – simply “plug and pull” modules during technology maintenance or upgrades. Modules themselves can be mixed and matched – reducing costs associated with spares.

Reliability You Can Trust
