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.

4.1 Quick Validation Guide for OEMs
For this section, the following example configuration is assumed:
Host
o System: 2U x 2 GPU server
o CPU: 2x Intel® Xeon® E5-2630 v4
o Memory: 16 GB per socket (2x DDR4 8 GB 2400 MHz DIMMs)
o Fans set to meet CFM requirements defined in Section 3.3 at card inlet temperature 35 °C.
Intel® VCA
o System: 2x Intel VCA 2
o Memory: 32 GB per node (2x DDR4 16 GB 2133 MHz DIMMs)
o Firmware: VCA_EXT_2.0.283
4.1.1 PCIe* Device Discovery and Enumeration
When recognized, each Intel VCA 2 lists the set of PCIe* devices shown in Figure 9. B/D/F may change based
on the system setup, but the number of devices (13) and names should match. To display the device list, use
the following command:
lspci | grep “(rev ca)”
Figure 9. PCIe* device discovery
For a quick check on PCIe link health, check the link status properties for each device. For a full example
dump refer to Appendix A. Link speed should be Gen 3 8 Gt/s. Lane count for the main PLX 8749 device
depends on host configuration; x16 is the highest available lane count interfacing with the host. Individual
nodes are expected to be Gen 3 8 GT/s x8 links. Not every port from PLX 8746 is used, so expect one link to
be 0 lanes Gen 1.
16
Intel® VCA 2 Product Specification and Hardware Guide
For the node, use the following command:
lspci –s 84:00.0 –vv
Figure 10. Node PCIe* link health
17
Intel® VCA 2 Product Specification and Hardware Guide
For the edge connector PLX, use the following command:
lspci –s 82:00.0 –vv
Figure 11. PLX PCIe* link health
4.1.2 Node Availability
To quickly verify that each node is up, run a status command from the Intel VCA utility. Return data is
expected to be a list of CPUs per card and each individual state. It is expected that there are three CPUs
listed per card and all are in the same status after a successful boot. To display CPU status, use the following
command:
vcactl status
Right after host reset, it is expected to see the status shown in Figure 12.
After booting the node’s operating system and network services are up, it is expected to see the status
shown in Figure 13.

4.1.4 Transcoding Benchmark for Simultaneous AVC-AVC Transcodes
This test attempts to extract the maximum number of simultaneous AVC transcodes while maintaining a
minimum of 30 FPS using Intel® Media Server Studio and a web-available video sample.
Target: Most number of simultaneous AVC transcodes achieved while keeping 30 FPS (real-time)
Test configuration: 2x Intel VCA 2 with all 6 nodes running simultaneous transcoding
Environment: Bare metal, non-persistent image
Transcoding software: Intel Media Server Studio 2017 (available at https://software.intel.com/
en-us/intel-media-server-studio)
Input file: blue_sky_1080p25_3min.h264 (available at https://media.xiph.org/ldv/pub/

4.1.5 Temperature Profile
The temperature while booted in idle mode is ~35 °C. Temperature during workload is expected to reach
~60 °C. During transcoding workload, the script runs the load twice to ensure frame rate achieved is correct,
hence the temperature curve between runs is expected.

4.2 Validating Hardware Compatibility
Mechanical, thermal, and power supply – Refer to chapters in this guide on mechanical, airflow, and
power supply specifications.
Shock and vibration – There are no special requirements for testing shock and vibration. Use the
standard testing procedure for PCIe* devices.
Power cycling – AC, DC, reset. Recommend minimum of ten boards (20 preferred) cycled 700 times
each at expected production ambient temperature with not failures.
4.3 Host Server BIOS Guidelines
BIOS enumerates and recognizes PCIe add-in cards, x16 Gen3
BIOS supports large MMIO regions ≥ 256 GB
BIOS must support BAR up to 64 GB per device
4.4 Host Server PCIe* Reset Guidelines
Signal – PERST_N, which is the PCIe reset signal coming from host
Duration – Not relevant, but 10 ms is suggested
Number of resets – Not limited, but strongly suggested two as maximum
Time between resets – Recommended to be at least three seconds

5.1 Memory Population Rules
Note: Although mixed DIMM configurations may be functional, Intel only supports and performs validation
with cards that are configured with identical DIMMs installed across all CPUs
All DIMMs must be DDR4 DIMMs.
Only Error Correction Code (ECC) enabled DIMMs are supported.
All processors must have at least one DIMM installed.
DIMM slots for each processor must be installed in order, beginning with DIMM Slot A.
When only one DIMM is installed for any given processor, it must be populated in the DIMM A slot.
5.2 Supported Memory

Visual Compute Accelerator Family Software Guide:
https://www.intel.com/content/www/us/en/support/server-products/server-accessories/000016708.html.
Intel VCA 2 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 that the
CPUs boot from.
Users have the option of downloading one of several different boot images available from the Intel website
or creating their own boot image. Refer to the Intel® Visual Compute Accelerator Product Family Software
Guide for instructions on how to build a boot image.
6.1 Supported Hypervisors
Xen
KVM
6.2 Guest Operating System
Intel VCA 2 supports any operating system supported by Iris® Pro graphics, Intel® Graphics Virtualization
Technology (Intel® GVT-d) virtualization, and the Intel® Media Server Studio.
