| Is the NVIDIA Quadro 4000 for Mac compatible with Echo Express Thunderbolt Expansion Chassis? | Aug-29-12 |
| No, the NVIDIA Quadro 4000 is not Thunderbolt-compatible. Apple and Intel have prescribed specific connectivity standards for products with Thunderbolt technology interfaces. These include drivers that are recognized by Thunderbolt and allow the product to connect and disconnect while the computer is running (hot plug/unplug). Products with Thunderbolt interfaces are tested by Intel and Apple and certified as compatible with these standards.
For PCIe expansion chassis to function correctly in this Thunderbolt-connectivity paradigm, the drivers for PCIe cards used in the chassis must also be updated to support these requirements. In most cases, each card manufacturer is responsible for updating the drivers for their cards. For the Quadro, it is Apple that controls the driver in OS X.
Intel has required all PCIe chassis manufacturers to agree to list only compatible cards that have been tested to support these standards. Apple has determined that for now, there are several technical reasons why it is not a good idea for a GPU card--including the Quadro--to connect over Thunderbolt. Therefore, GPU cards do not have Thunderbolt-compatible drivers. Until Thunderbolt-compatible drivers are released for GPU cards, they will not work over Thunderbolt. |

| I installed an LSI 9200 series SAS RAID card in a Thunderbold expansion chassis and now the LSI card doesn't work. | May-22-19 |
| The LSI card probably blew its fuse. LSI seems to be unique in putting a fuse in series on the power input of some of its PCIe cards, which is a non-standard implementation for a PCIe card design. The fuse on the LSI card is sized too low and may sometimes blow at the inrush current the LSI card demands at power up. (In the PCIe specification, it is not the responsibility of the system to limit the inrush current to the card.)
The fuse could have been omitted; it was not. The fuse could have had a higher rating; it did not. The fuse could have been a slow-blow type; it was not. The fuse could have been user replaceable; it is not. The fuse could have been a resettable type; it is not.
From our resellers, we have heard anecdotes of LSI cards blowing their fuse in some systems and not others, apparently depending on how fast the 12V power comes up. Power would generally come up slower in a server in which the motherboard places a low-impedance demand on the power supply. In Thunderbolt expansion chassis, there is no motherboard to draw power, and the power supply voltage comes up rather quickly. This is LSI's issue to solve. |
