Advisory Note:
The Intel® Visual Compute Accelerator card 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 VCA card will get hot. The card covers must be in place to allow for proper air flow
over and through the card assembly. Failure to have the card covers installed will result in the card
overheating which may impact card performance or proper operation.
3.3 Thermal and Air Flow Specification
The following illustration and table identify the thermal, air flow, and air pressure requirements that must be
met by a chassis following a common front of system to back of system air flow pattern.
*CFM=Cubic Feet per Minute
*“H2O= Inches of Water
Some custom chassis configurations may orient the card such that the air flow is reversed from the standard
air flow pattern shown above. In these non-standard system configurations the thermal, air flow, and air
pressure boundary conditions must meet the following requirements.

Note: VCA card CPU core temperatures must remain at or below 96° C (204.8° F). CPU’s will begin to
throttle once they reach 105° C (221° 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, system
administrators must make adjustments to the system fan speed controls to ensure increased air flow to the
VCA card.
System administrators can utilize the “vcactl temp” command of the vcactl utility to monitor VCA CPU core
temperatures.

Intel® Visual Compute Accelerator Product Specification and Hardware User’s Guide
5. Operating System Support
Note: All utility software and boot images referenced in this section can be downloaded from the following
Intel web site: https://downloadcenter.intel.com/product/87380
The Intel® Visual Compute Accelerator boots the operating system from the host using a technology known
as Leverage Boot. A “vcactl” utility is used to perform all boot operations. The utility loads the operating
system into a RAMDisk which the CPU’s boot from.
Users have the option of downloading one of several different boot images available from the Intel web site
or creating their own boot image. Refer to the Intel® Visual Compute Accelerator Product Software Users
Guide for instructions on how to build a boot image.
Alternatively, an option for building a guest OS with pass through graphics is available by using GVT-d
virtualization.
For the host operating system, a virtIO driver and a utility are required. The driver and utility are currently
tested with CentOS* 7.1 (kernel update require).
Disclaimer Note: As these drivers are open source, the option to build them for other Linux based operating
systems is available, however Intel cannot provide support for this option without official validation being
performed by Intel. Driver validation and performance tuning will be the responsibility of those that choose
to build drivers for Linux Operating systems beyond those supported by Intel.
5.1 Supported Host Operating Systems
- CentOS* 7.1 with kernel update
Note: specific kernel updates are documented in the Intel® Visual Compute Accelerator Product Software
Users Guide.
5.1.1 Reference boot OS on Visual Compute Accelerator
CentOS 7.1 with kernel update
- Persistent Image – Automatically mounts to pre-defined NFS partition on the host. Enables all
changes to remain persistent
- Baremetal Image – Full CentOS 7.1 image. By default nothing is persistent.

6. Light Guided Diagnostics
The Intel® Visual Compute Accelerator Board includes several LEDs to indicate the health of the card.
6.1 Power LEDs
Two LEDs located on the back edge of the card, and visible externally from the back of the system, are used
to indicate the status of power to the board. One AMBER LED to indicate the status of 3.3V auxiliary power
and one GREEN LED to indicate the status of 3.3V main power. Each LED should be illuminated when power
is present.

6.2 Processor CATERR LEDs
Three LEDs on the back side of the board (viewable when the system is open) are used to indicate when a
CATERR for a specific CPU has occurred. When a CATERR on a specific CPU is detected, the given LED will
illuminate RED. In a normal state, these LEDs are not illuminated.
Figure 5. Light Guided Diagnostics - Processor CATERR LEDs

Intel® Visual Compute Accelerator Product Specification and Hardware User’s Guide
7. BIOS Image Selection Jumpers
The Intel® Visual Compute Accelerator card includes three 16MB SPI Flash devices to store separate BIOS
images for each processor. Each flash device will store two BIOS images; a locked factory default image, and
a modifiable User Defined image. As shipped from Intel, both BIOS images for each processor will be the
factory default.
On the back edge of the VCA card is a set of three jumper blocks. Each jumper block is used to switch the
BIOS image for a given processor between the User Defined and the Factory Default. With the jumper in
place over the two stake pins (Default), the processor will boot using the User BIOS image. In the rare event
the User Image should get corrupted, the jumper can be removed to boot the processor using the Factory
Default image.
NOTE: All three jumper blocks should either be installed or removed together. At no time should one jumper
setting be different from the other two.
NOTE: The back edge of the VCA card includes several stake pins that are not used and have no functionality.
Care should be taken when restoring BIOS Image jumper blocks to their proper stake pin locations. See

Appendix A: Intel Server System Support
Intel® Server System R2000WT product family
Server System
R2208WTTYC1R - full server system with full support for 2x Intel® Visual Compute Accelerator cards
Support Criteria
Due to air flow and thermal limitations, the Intel
®
Visual Compute Accellerator card can only be supported
in the following base Intel Server System R2000WT system models: R2208WTxxxx.
Components
1x R2000WTXXX + 1x AWTCOPRODUCT + (1x or 2x) A2UL16RISER2 (if 1, also add 1x A2UL8RISER2) + 2x
AXX1100PCRPS + 1x (A2U8X25S3HSDK (no NVMe support) OR A2U44X25NVMEDK2 (with NVMe
support). Processors, memory, drives, and additional add-in cards sold separately.
The Intel
®
Visual Compute Accellerator card must be installed into the top slot of a 2-Slot PCIe* Riser
card. With a 2-slot riser card installed, the embedded fan speed control will operate system fans at a
higher speed. 3-slot riser cards (as shipped in the standard platform configuration) cannot be used due
to air flow and thermal limitations, as embedded fan speed control will not drive system fans to higher
speeds needed to support the thermal requirements of this card.

Figure 7. 2-Slot PCIe Riser Card
Intel® Visual Compute Accelerator Product Specification and Hardware User’s Guide
Figure 8. Auxiliary 12V Power Cable (iPC AXXGPGPUCABLE)
Riser slots 1 and 2 are capable of supporting up to 100W maximum power each. Available power to each
add-in card slot on a given riser card is defined by the PCIe* specification. Add-in cards with power
requirements above 75W will require the additional power to be drawn from either of two 2x2 pin
“OPT_12V_PWR” connectors on the server board. A 12V Aux power cable is routed from the “OPT_12V_
PWR” on the server board to a 6 or 8 pin 12V AUX power connector located on the add-in cards.
NOTE: Both the 2-Slot PCIe Riser card and the 12V Auxiliary Power cable are included in Intel Accessory kit
A2UL16RISER2
High power add-in cards with passive cooling solutions (no fan on the heat sink) can only be supported
in systems configured with the high air flow air duct included in Intel Accessory Kit AWTCOPRODUCT.
Figure 9. Air Duct included in Intel® Accessory Kit AWTCOPRODUCT
AWTCOPRODUCT Air Duct notes:
The high air flow air duct included in Intel Accessory Kit AWTCOPRODUCT includes two plastic knock-out
panels to allow for additional air flow over a specific riser card area. A knock-out panel is only removed when
installing a high power add-in card that meets the following criteria:
o Double wide
o Passive Heat Sink Solution (heat sink with no fan attached)
18
Intel® Visual Compute Accelerator Product Specification and Hardware User’s Guide
If the add-in card does NOT meet these criteria, the given knock-out panel should NOT be removed.
When installing a double wide add-in card with a passive heat sink solution, remove only the plastic knockout from the side on which the add-in card is installed. Only remove both plastic knock outs when installing
two cards that meet the criteria defined above (1 per riser card). Once a knock-out panel is removed, it
cannot be re-installed.
A system configured with the contents of Intel Accessory Kit AWTCOPRODUCT and an Intel
®
Visual
Compute Accellerator card can also support the following additional PCIe* add-in card configurations.
o PCIe* add-in cards with minimum 100 LFM (0.5 m/s) or 200 LFM (1m/s) air flow requirement can
be installed in any available add-in card slot in Riser Card #1, Riser Card #2, and Riser Card #3 (if
installed)
o PCIe* add-in cards with a minimum 300 LFM (1.5 m/s) air flow requirement can be installed in the
bottom add-in card slot of Riser Card #1 and Riser Card #2.
o PCIe* add-in cards with air flow requirement greater than 300 LFM cannot be supported
Systems configured with an Intel
®
Visual Compute Accellerator card card must have a shipping bracket
installed before the system is exposed to any level of shock or vibration or is transported to the end user
location. Failure to install the shipping bracket has the potential to cause serious damage to various
components within the system. The shipping bracket is only available as part of the following Intel
Accessory Kit: AWTCOPRODUCT.
Figure 10. Shipping Bracket
19
Intel® Visual Compute Accelerator Product Specification and Hardware User’s Guide
Figure 11. Shipping Bracket Placement
With no shipping bracket installed, the air duct has support for the addition of up to two SSD Storage
devices mounted to the air duct via fastener screws. Mounting standard hard disk drives to the air duct is
NOT a supported configuration. Mounting hard disk drives to the CPU air duct may cause data loss,
performance degradation, and premature drive failures.
High power add-in cards that require up to 300W can be supported. A total system power budget should be
calculated to determine if the power draw of the desired system configuration meets the power limits of the

Intel® Server System R2000WT family Fan Speed Control
The following IPMI script was developed to provide fan speed control for the Intel® Server System R2000WT
product family. The script changes the default Pulse Width Modulation (PWM) offset of the system fans to a
value that provides enough airflow to maintain the ambient temperature of the VCA card processors below
96°F. The temperature is retrieved by calling ‘vcactl temp’ and then as the temperature goes above 95
degrees the fan speed increases. If the temperature drops below 90 degrees the fan speed will decrease.
The amount it increases is proportional to how much beyond that threshold the temperature spikes. This
offset is beyond the fan speed control already implemented in the BMC so not to impact other components
the BMC manages.
