GPU adapters
The server supports the co-processors and graphics processing units (GPUs) that are listed in the
following table. Each is installed in a Full-length I/O Book. No other adapter can be installed in the
Full-length I/O Book. The Full-length I/O Book includes the necessary auxiliary power cables.
Notes:
These adapters are not available through CTO and cannot be shipped installed in the server because
they are installed in the Full-length I/O Book, which extends beyond the rear of the chassis (see
Figure 12). These adapters must be shipped separately from the server. Order the adapter and
Full-length I/O Book as separate options.
If a NVIDIA Grid K1, Grid K2, Tesla K20c, Tesla K40, Quadro K4000 or Quadro K6000 is installed,
the maximum system memory that can be installed is 1 TB.
