The Grizzly is a rugged embedded server unit (ESU) featuring an Intel 16-core processor, two 10 Gigabit Ethernet SFP+ ports, four Gigabit Ethernet ports, and up to 128 GB of ECC memory. This combination makes it ideal for applications requiring very high performance processing and high data bandwidth. Additionally, two Mini PCIe sockets and a PCIe x4 M.2 site provide for on-board I/O expansion and high speed / high-capacity on-board storage. The Grizzly also contains additional interfaces including USB, serial and digital I/O, and SATA.

The high performance capability of the Grizzly make it ideal for situations where data gathering and processing need to be kept local for security or latency reasons, or to provide local cloud capability. A 16-core processor coupled with up to 128 GB of ECC memory supports the use of hypervisors for the running of virtual machines. The 10 Gigabit SFP+ ports permit very high speed connectivity. Networks can be created using plug-in copper, short-reach fiber, or long-reach fiber transceivers.

The Grizzly is based on the COM Express Extended form-factor, but it is delivered as an assembled and tested, production-ready embedded computer. Like all VersaLogic products, the Grizzly is engineered and tested to be rugged. It is fully validated for operation in unforgiving environments with extreme temperatures and mechanical shock and vibration. Each component has been carefully sourced, and the design optimized and validated, to ensure reliable operation in the field.

VersaLogic's 10+ year product life support programs ensure long-term deployment in the field, free from expensive upgrades and migrations that come from short, disposable lifecycle products.

VersaLogic products are designed for use by OEMs working in a variety of market applications: Aerospace, Defense, Energy, Industrial, Security, Medical, Military, Robotics, and Transportation. Anywhere that the need for superb quality and high-performance embedded computing exists, applications include: automation, avionics, gateway, in-vehicle, monitoring, simulation, and vision.

VersaLogic delivers extremely reliable standard and customized embedded computers backed with unsurpassed service and the highest availability in the market. VersaLogic exists to exceed customers' product, service, support and delivery needs - whenever and wherever the need arises.
