The Impregnable Server System



Modular approach

Groundbreaking Technology

The S1U401-SHS secure storage server "Hurricane" is an ultra-rugged, 1U rack mount, lightweight Intel® Xeon® "flash server" system with expandable and removable Direct-to-disk™ storage at the drive- and cartridge-level, with 12x or 24x 1GbE Ethernet ports and dual QSFP+ sockets for 10/40 Gbits/s Ethernet add-in modules. The Secure High Speed Storage (SHS) in Hurricane integrates with high-performance processing, encrypted and removable RAID storage, networking, high speed I/O, and a MIL-SPEC power supply plus an optional APU in a small, ultra-rugged 1U high rack-mount enclosure with the greatest possible performance per dollar and per watt.

High Speed Storage

Flash solid state disks (SSDs) coupled with the Intel® Xeon® E5 and PCIe/SAS/SATA 3rd generation busses make this the fastest “flash server” in the rugged market.


General Micro Systems' SecureDNA™ software suite, firmware and system architecture assure that data is protected at-rest and in-flight via RAID controller-side encryption.

Multi Domain

System architecture simplifies deployable MIL-SPEC technology for Multiple Independent Levels of Security (MILS), NSA Red/Black network separation, or system redundancy.

Ultra-High Performance

The S1U401-SHS is fundamentally a high-performance rack mount server that supports the latest, most power-efficient Intel® Xeon® E5 with Hyper-Threading for a total of up to 18 physical cores (36 logical cores) operating up to 2.1 GHz and having the ability to TurboBoost up to 3.3 GHz. To harvest this incredible CPU performance, the CPU is coupled with up to 256 GB of DDR4 RAM organized in four banks with ECC support (2-bit error detection and 1-bit error correction). All these Xeon® cores with Hurricane's I/O can be used to create multiple secure virtual machines (VMs) that can replace up to 36 separate single-processor systems in only 1U: this is a stunning size, weight and power (SWaP) savings.

Drives, Secure NAS Cartridges and RAID


Expandable and removable storage at the drive- and cartridge-level.

Primary Direct-to-disk™ storage comes from four front panel removable SSD flash drive trays which can each accommodate one SAS-3 or SATA III drive. Software RAID is provided by Intel® RSTe to these drives. Additionally, an optional encrypting hardware RAID controller and two 8-drive removable cartridges can be added to provide 16 additional SAS/SATA/NVMe (PCIe) drives and a whopping 128 TB of storage (using 8 TB drives). RAID 0, 1, 5, 10, 50 or custom configurations are possible, allowing redundancy and fault tolerance of drive groups, both cartridges, or user-customizable clusters. Drives can be self-encrypting (OPAL), FIPS-197 or FIPS-140-2 certified, and the cartridges use either HDDs (for low cost) or SSDs (for ultimate speed and reliability).


Supports one 1 Gigabit Ethernet service port and 12x or 24x 1 Gigabit Ethernet ports (copper) as standard. Two QSFP+ sockets which each can be populated for 10/40 GbE using copper or fiber and many combinations are available via add-in QSFP+ modules.


The CPU platform supports PCI Express Gen 3, USB 3.0 and SATA III for the highest performance possible on a server platform. On Hurricane, General Micro Systems has used PCI Express Gen 3 extensively as the backbone of the S1U401-SHS system.


Additional standard I/O includes: four USB 3.0 ports, a 1 Gigabit service Ethernet port and high-definition VGA/DVI-I console video (no audio). Using a GMS SAM I/O™ PCI-Mini add-in module, SMPTE HD-SDI long-reach video can be added via panel-mounted BNC connectors.


Three internal fans act as a multi-redundant thermal system with intelligent fan control (or optional BMC-based control), providing high confidence and high MTBF. Should one fan fail, the others can contain operational temperature for a period of time sufficient to shut down the system. The storage subsystem also includes dual TwoCool™ fans to maintain acceptable cartridge temperature.
