Dell m1000e enclosure loud running ESXi 4.1 U1

We have a Dell m1000e enclosure that is filled with 8 Dell M710 blade servers.

4 of the blades are running ESX 4.0 u1. The fans associated with those blades run quietly. The 4 other blades which we have have configured to run under ESXi 4.1u1 run like there is no OS on those blades (they are loud).

What are we missing in getting those blades running ESXi 4.1u1 to run like the older ESX 4.0 blades rather than sounding like they would when starting them up all of the time. They ran quietly when they ran ESX 4.0u1?

    First place I would look at is dell, see if there is no fan firmware update advisory for running ESXi 4.1

    I think I know exactly what this is, and the same issue occurs with HP servers, where there is no hardware support for the servers in ESXi. In a HP Server, you would load HP System Insight Agents which would interface with the hardware, which would control the fans. But in ESXi 4.1 which is not officially supported for the HP DL385 and DL585, the fans run at high speed, and never run at low speed, because there is no support for the servers.

    I have checked your servers and there are on the Hardware Compatibility List, I wonder have you added the CIM providers OEM bundle on the ESXi 4.1 servers?

    in the vsphere gui client, can you check hardware configuration? does it display information about the server?

    (slap to the head). I forgot that under ESXi, that the OEM providers would be providing customized versions of ESXi and their utilities. Will try it and let you know what I find.
