Ozark 3U VPX Storage Module

The Ozark is a mass storage module that integrates the latest high speed PCIe/NVMe SSDs into a rugged 3U VPX package. The SSD conforms to the common U.2 form factor and its specifications can be tailored to the end-user’s requirements.

MSS provides a variety of field-tested features including:

  • OpenVPX compatibility
  • Multiple interface and capacity options
  • Shock & vibration protection
  • Extreme temperature resistance
  • Simplified PCIe integration
  • Direct-attached storage (DAS)
  • Removable storage
  • AES 256-bit encryption
  • Military erase algorithms

The Ozark can be modified to widen its capabilities, including aligning it with the latest SOSA standard.

MSS is always open to consider specific requests and customizations. We listen closely to our customers and their needs by building strong, collaborative relationships with OEMs and Suppliers.

Simply put, no one can match MSS’s meticulous attention to detail and proven track record of delivering world-class performance in harsh, demanding environments.

1. Depends on SSD selected.
2. Depends on final system configuration, transfer block size, thermal throttling, etc.
3. Sequential performance is measured with 128KB transfer size, QD 32 and 4KB align with IO Meter.
4. Thermal value is the rail edge temperature.
