The Intel® Visual Compute Accelerator 2 (Intel® VCA 2) equips Intel® Xeon® Scalable processor and Intel®
Xeon® processor E5-based platforms with Iris® Pro Graphics and Intel® Quick Sync Video media transcode
capabilities. Comprised of three Intel Xeon processors E3 1585L v5, this PCIe* add-in card delivers
outstanding total cost of ownership and is supported by a rich ecosystem of server OEMs, ISVs, and
solutions. Applications include:
Broadcast – Ultra-high channel density with high visual quality.
Remotely rendered graphics – High video quality, low latency graphics for enterprise productivity and
anytime anywhere gaming.
Multi-party communication – Video-enabled B2B, B2C, and C2C communication with massive scaling

2.3 Host System Required BIOS Features
The host system BIOS must be configured to enable large memory-mapped input/output (MMIO), and allow
for large per-device base address register (BAR) allocations. BAR must have 64-bit address enabled.
The minimum requirements for BAR and MMIO are:
MMIO mapping above 4 GB is enabled
Minimum MMIO size is 4 GB/CPU (node)
For example, on Intel® Server Board S2600WT based systems, this can be enabled in BIOS setup by
configuring the following two options on the PCI Configuration screen.
Set Memory Mapped Above 4 GB to Enabled
Set Memory Mapped IO size to 256 GB
2.4 Host System Minimum Memory Requirements
The host system must have sufficient free RAM (after accounting for operating system, running services, and
applications) to load the bootable image for each node to be simultaneously booted. (For example, if a 2 GB
bootable image would be booted simultaneously on four cards (12 nodes), there must be at least 24 GB (2
GB x 12 nodes) of free RAM when the boot command is issued.)

3. Board Specifications and Support Requirements
3.1 Mechanical Specification
Intel® VCA 2 is a “near” full-length, full-height, double-width PCIe* 3.0 x16 add-in card. It includes a bracket
that extends the card to full length for systems that fully support the PCIe specification.

3.2 Card Assembly
The Intel VCA 2 assembly consists of several detachable components to allow for card configuration and
serviceability. Figure 3 displays the full card assembly.
Figure 3. Intel® VCA 2 detachable components
Advisory Note: Intel VCA 2 must have the provided mechanical support bracket (or other custom support
bracket) mounted to the card to ensure proper support when installed in the system. Failure to properly
support the installed card may cause serious damage should the system be exposed to any level of shock or
vibration or is transported to the end user location.
When in operation, the card temperature will rise. The cosmetic cover, thermal module, and duct must be in
place to allow for proper airflow over and through the card assembly. Failure to have the card covers
installed results in overheating which may impact performance or proper operation of the card.

3.3 Thermal and Airflow Specification
Figure 4 and Table 4 identify the thermal, airflow, and air pressure requirements that must be met by a
chassis following the front-to-back air flow pattern of a common system.
Figure 4. Standard airflow pattern
Table 4. Requirements for standard airflow pattern
Some custom chassis configurations may orient the card such that the airflow is reversed from the standard
airflow pattern shown above. In these non-standard system configurations, the thermal, airflow, and air
pressure boundary conditions must meet the following requirements.
Figure 5. Non-standard airflow pattern
Table 5. Requirements for non-standard airflow pattern
Note: Intel VCA 2 CPU core temperatures must remain at or below 96 °C (204.8 °F). CPUs begin to throttle
once they reach 100 °C (216 °F), impacting card performance. Should CPU temperatures continue to rise, the
card may shut down due to a CPU Thermal Trip event. Should such events occur, adjustments must be made
to the system fan speed controls to ensure increased airflow to the card. The vcactl temp command of the
vcactl utility may be used to monitor card CPU core temperatures.

3.4 Power Specification
Intel VCA 2 has a maximum TDP of 235 W. Per the PCIe specification, the PCIe x16 connector can support up
to 75 W. The remaining power to the card must be supplied via the 2x3 (75 W) and 2x4 (150 W) 12 V AUX
power connectors on the card as shown in Figure 6.
