12. Is the PCIE card referred above called HIB38x-16 PCIE host target interface? (To me it looked like these are inserted in the slot on the
expansion box backplanes. Without a card to be inserted in the host server - how would it connect to any server?).
Answer: Host interface card. It comes with the expansion box. It is installed in a x16 PCIe slot in a host computer motherboard.
The chassis is not limited to x16, It can also support a x4 and x8 Host Interface Board
.
13. Can I connect two hosts (servers) to this system(expansion box)? Or do the cards have to be connected to the same server?
Answer: Yes. You can connect the two host servers and YES you can connect to the same server.
14. You have two backplanes with 6 slots and each of those backplanes also have one PCIE switch. Is this the same PEX8733 switch
referred to in the HIB38x-16 host target interface.
Answer: Yes, the two backplanes have the same switch, it is Broadcom PEX8796 PCIe3 switch. The HIB38x-16 host / target interface
cards have Broadcom PEX8733. OSS-457 has 6 x16 slots.
15. Do the two backplanes with 6 slots have the same PEX 8733 which as the HOB38-x16?
Answer: No, they have 8796.
16. Are the PCIe switches connected to each other (backplanes connected to each other) so that with one server connected to the
expansion box with one cable I can access 5 PCIe card slots? Or is it one server to access all the 5 slots only with two PCIE cables?
Answer: The two backplanes are independent and there is not any connectivity between the two. You need two PCIe cables to
access 10 slots.
17. If the PEX switches in each backplane are connected to each other I need a configuration where in one state one host server acts as
the root hub for all the 5 PCIE cards and if that host server fails the second server connected to the second backplane takes over as
the root hub for all the 5 PCIE cards? Is this possible with this product?
Answer: Not applicable since there is not any connectivity between the two PCIe switches.
18. Can I unplug the link cables while the expansion unit and the host computers are running?
Answer: It is not recommended to unplug or plug in the link cables (x16 cable) while the expansion unit and host computers are
running as this can cause failure.
19. Can I update my unit to have a fan control or PWM capability:
Answer: Yes, but you have to send the entire unit (as RMA) to OSS to perform the update (PWM capability ).
20. Can I buy aux power cables for my unit?
Answer: Yes, contact OSS Sales for more information.
21. How many dual-width / double-wide GPU can I install in the unit?
Answer: You can install a total of 8 double-wide / dual-width GPUs. Four dual-width / double-wide GPUs per 457 OSS board.
22. How many single-width / single-wide GPU can I install in the unit?
Answer: You can install a total of 5 single-width / single-wide GPUs in the unit. Four doubles-wide GPUs can be accommodated.
23. Can I leave my GPU cards in the expansion unit when sending it back to OSS for service?
Answer: NO, GPU cards must be removed from the slots when transporting or shipping the unit as this can break the slot or damage
the card.
