Description
The VT805 is a four-slot chassis that accommodates four x16 PCIe style modules.
Power Supplies
The VT805 can accept up to four power supplies that can provide 2+2 redundancy. The VT805 has a Power Entry Module (PEM) that manages power to each slot. The VT805 has options for Universal AC, +28V DC and +48V DC power supplies.
Cooling
The VT805 has an intelligent fan controller and the cooling is front to back.
Routing between modules
The VT805 chassis provides x4 lanes to each slot as a full mesh between the slots. From each module there is a 100G interface to the 100G Switch.
Integrated 100GbE Switch
The VT805 has a 100GbE Switch that allows each of the PCIe modules to connect via a cable or use the 4x SERDES on the PCIe Edge to connect to the switch. The VT805 has quad QSFP28 in the front panel. Each QSFP28 can be configured by software to run as:
- Single 100G or 40G
- Quad 25G/10G/5G/2.5G/1G (any mix combination within the quad ports is allowed)
In total the VT805 has 4x 100/40G and/or any combination of 16x 25G/10G/5G/2.5G/1G.
Integrated BMC
The VT805 has a health management controller on board which follows the IPMI specification. This allows dynamic cooling of the chassis as well as provide health management to the upper protocol.
Integrated USB HUB
The VT805 has a USB Hub on board that allows each module to connect via cable to the hub.
Integrated JTAG Switch Module (JSM)
The VT805 has a JSM to allow all four slots to be managed thru a single JTAG connector or via GbE using a Virtual Probe functionality.
Chassis Locator
Each chassis could be assigned a unique Chassis Locator (CL) to uniquely identify the chassis among multiple chassis within the larger system.
