NVIDIA Tesla D870
Overview
The NVIDIA®Tesla™D870 Deskside Computing System features two Tesla
graphics processing units (GPUs) and can be used either alongside a workstation or
alternatively, two deskside systems can be rack-mounted for four Tesla GPUs in a
3U configuration (it is possible to rack-mount just one deskside unit).
The Tesla D870 connects to a host workstation via a low-power PCI Express ×16
or ×8 adapter card.

Specification
System Chassis
The Tesla D870 can be used as a deskside unit or alternatively, two deskside systems
can be rack-mounted for four Tesla GPUs in a 3U configuration. The rack-mounted
deskside conforms to the EIA 310E specification for 19” 4-post racks with 900 mm
to 1000 mm depth.
Note: It is also possible to rack-mount a single deskside in a 3U configuration.
The chassis dimensions are:
Tower desktop: 9.54 inches high × 5.94 inches wide × 20.6 inches deep
Rack Mount: 5.25 inches (3U) high × 8.5 inches wide × 18 inches deep

Host Adapter Card
The NVIDIA PCI Express interface card (Figure 4) comes with a standard (long)
bracket as well as a shorter low profile bracket that conforms to the PCI Express
low profile form factor. The specifications for the interface card are:
Form factor: 6.6 inches × 4.376 inches
Power draw: 10 W (maximum)
Cooling: Passive heat sink (no fan)
Bus: PCI Express ×16
An optional PCI Express ×8 host interface card can be purchased separately.
