GPU and FPGA
The T640 supports up to 4 double wide GPUs, up to 300W each, or up to 8 single wide GPUs, up to 150W each, with the following
restrictions:
•
Must have 2 CPUs installed
•
GPUs must be identical
•
CPU TDPs of 150W/8C, 165W/12C(WS SKU), 200W and 205W have an ambient limit of 30C
GPUs on the T640 support
scientific
computing, co-processing and VDI/Flex (Virtual Desktop Infrastructure) architectures. The
T640 can support four 300W, full-length, double-wide GPUs. Each GPU can support of dedicated memory and is either actively
cooled or passively cooled. The GPUs are installed on the PCIe x16 Gen 3 interfaces available on Slot 1, 3, 6 and 8. (Slot 6 and 8 will
only work with CPU2 populated.)
If a GPU is on slot 1/3, only 1x 5.25” RMSD device (ODD/RD1000/half-height tape is supported). 300W GPUs only support the
maximum ambient 30 degree C condition.
Requires a GPU-ready chassis in a rack form factor (GPUs are only supported in rack mode). 3.5 inch x18 HDD chassis is not
supported. Dual PERC (x32)
configuration
is not supported. Fresh Air
configuration
is not supported.
The GPU ready chassis has to be chosen during the initial purchase transactions.
