The status for a particular GPU-Xpander can be viewed by selecting the GPU-Xpander model name in the tree.
GPU-Xpander model names refer to the backplane circuit board used within the enclosure, and have the format "A0xxxx(n)"
where "xxxx" is a 4-digit number identifying the backplane model, and the number (n) distinguishes among multiple backplanes
within a GPU-Xpander enclosure.
This window has tabbed selections at the top, with the default tab being "backplane".
This window displays identifying information for the GPU-Xpander hardware, followed by a list showing the slot configuration.
The columns in the slot list are:
Slot #: Slots in GPU-Xpander are numbered starting at Slot#1, which is the right-hand slot in the backplane, and continuing right-to-left.
The "Cable" slot refers to the hardware attached to the PCI Express cable.
- Port#: The port number is an internal configuration detail used for technical support purposes.
- Type: Slot types are normally "Downstream" for GPU slots, and "Upstream" for the Cable Slot.
- Max Link Width: is the maximum number of PCI Express Lanes available to that slot.
- Link Width: is the actual number of PCI Express Lanes in use for that slot. The Link Width is zero when the slot is unpopulated.
- Max Link Speed: is the maximum PCI Express link speed available to that slot.
- Link Speed: is the actual PCI Express link speed for the slot; usually 2.5Gbps for PCIe Gen-1 devices, and 5.0Gbps for PCIe Gen-2 devices.
Note however, that some GPU devices that are capable of Gen-2 speed fall back to Gen-1 link speed when not in use.
- Bandwidth: The theoretical bandwidth available for that slot in Gigabits/second .
- Link Use Ingress: A measure of the bus utilization at port ingress, sampled over the most recent 5-second period.
- Link Use Egress: A measure of the bus utilization at port egress, sampled over the most recent 5-second period.
- Correctable Errors: The number of correctable errors on each slot since agent startup.
A small number of correctable errors over time is normal.
- Device: the GPU or other PCI device fitted in the slot. Unrecognized devices have a numerical representation.
For GPU-Xpanders fitted with Fan monitoring and control, the state of all chassis fans is monitored, and failure of either fan
causes a "FAULT" alarm to be generated.
The Fan speed can be set to either "Auto" (fan speed is set automatically according to the temperature measured inside the GPU-Xpander chassis),
or "Full On" which sets the fans to run Full Speed at all times.
The Enclosure Name is an optional text description that can be used to assign multiple GPU-Xpander backplanes to a larger enclosure.
To create an enclosure name, type in any text description into the "Enclosure Name" box, and press the Enter key.
To add the selected backplane into a particular named enclosure, select the enclosure name from the drop-down list.
Note: Enclosure configuration is not saved on program exit.
