GPU card installation guidelines
Observe the following guidelines while installing a GPU card:
•
GPU are supported only in the Rack mode configuration.
•
GPU can be installed only on systems that have 1100 W or higher power supply units.
•
Each GPU card supports up to 32 GB of dedicated GDDR5 memory.
•
Two double-width GPU cards on a single processor configuration and four double width GPU cards on a dual processor configuration
do not support any other add-on cards.
•
The GPU cards must be installed:
•
On GPU enabled system (two processor and also contains the main air shroud and GPU air shrouds).
•
On systems that support one 5.25-inch removable media storage devices.
•
On systems with eight fan configuration (Fan1, Fan2 are standard (STD) fans. Fan3-Fan6 are high-performance (HPR) fans. Fan7
and Fan8 are external Left and Right fans).
•
Specific GPU cards will need the use of the dongle power cable.
GPU card installation restrictions
•
Four double-width 300 W GPU cards on a dual processor configuration or two double-width 300 W GPU cards on a single processor
configuration cannot operate at an ambient temperature above 30 °C.
•
Two single-width GPU cards on a single processor configuration and four single-width GPU cards on a dual processor configuration do
not support a second PERC card.
•
The right external fan is required when a GPU is installed in slots 1 and 3.
•
The both left and right external fans are required when a GPU is installed in slots 6 and 8.
•
A GPU enabled system does not support Fresh Air Cooling.
•
The 18 x 3.5 inch hard drive system do not have support for GPUs.
