HP Proliant DL380 G6 with HP 1.28TB Multi Level Cell PCIe ioDrive Duo

[pezzotto]

Hello guys,

I've buyed an HP 1.28TB Multi Level Cell PCIe ioDrive Duo for my Proliant DL 380 G6.

This board absorb 25W from the PCI-E bus, but require an external power to reach the best performace (it will never exceed 55W anyway).

Unfortunately, I've not found any cable into the package so I discovered that I can force the driver to absorb the required power via the PCI-E bus, using the FIO_EXTERNAL_POWER_OVERRIDE parameter.

From the server specs I see that the mainboard PCI-E x16 riser slots can provide up to 75W each. My server is equipped with the standard x16 riser card that have 2x PCI-E x4 and 1x PCI-E x8 slots. The board is connected to the x8 slot, while the other slots is empty.

The question is: can the x8 slot provide more than 25W ?

Thank you for your attention,

Pasquale

Hi,

We had a similar issue on one of our G7 servers and we used this switch on a x8 slot and it was able to supply that power.  But i am not sure of G6 system board.

Thank You!

Hello Suman,

Thank you  for your reply! Please see here, seems that the slot doesn't support the requested power:

~ # fio-pci-check

Root Bridge PCIe 2000 MB/sec needed max

      ioDrive 00:13.0 (1005) Firmware 0
          Slot Power limit: 25.0W (25000mw)

      ioDrive 00:14.0 (1005) Firmware 0
          Slot Power limit: 25.0W (25000mw)

However, 'll try to set the switch anyway and let you know the result.
