Table 13. Full-Height Servers Per Power Supply Configuration - Dell PowerEdge M1000e Technical Manual

Dell recommends that all customers running a power-hungry configuration should install the
modular iDRAC with Lifecycle Controller firmware 3.02 upgrade, which contains the following
enhancements:

Improved calculation for power budgeting to enable more servers to be powered up
simultaneously.

Functionality to enable iDRAC with Lifecycle Controller to retry power up for blade servers
automatically in the event that some servers do not power up initially due to the pre-boot power
inventory.
Full-height blade servers
Table 13 lists the maximum number of recommended half-height blade servers per power supply
configuration according to the following server definitions:

Light configuration: 2 x 95W processor, 4 DIMMs

Medium configuration: 4 x 105W or 2 x 130W processors, 16 DIMMs

Heavy configuration: 4 x 105W or 2 x 130W processors, 32 DIMMs

The following information is applicable for full-height blade servers:

Throttling (performance reduction to conserve power):
220-240V power:
—
2 PSUs — Throttling will occur if heavily configured blades are worked very hard at the
>
same time.
3 PSUs:
>
o 4 processors — Some throttling will occur if heavily configured blades are worked
hard at the same time. Minimal throttling is expected for 16-DIMM configurations.
o 2 processors — Throttling may occur if all servers are run under a very heavy load and
have 130W processors and/or 32 DIMMs populated. Minimal throttling is expected
with 95W processors and/or 16 DIMMs.
