Support Principles

Direct engineering support, not script-reading triage.

We treat operational support as an ongoing engineering discipline. When complex anomalies occur, you engage directly with engineers who understand silicon architectures, bus dynamics, and thermal physics.

01

Root-Cause Engineering

We analyze why an anomaly occurred in the context of the entire hardware and workload ecosystem rather than applying temporary patches.

02

Direct Technical Access

Support communications connect directly with systems engineers and hardware architects who understand the platform design.

03

Proactive Telemetry

Continuous thermal, power, and memory channel health telemetry helps detect emerging constraints before they degrade mission workloads.

Diagnostic Guidance

Systematic diagnostic & troubleshooting methodologies.

Structured investigative workflows for isolating hardware, fabric, and firmware anomalies across enterprise systems.

Diagnostics & Health

ECC Memory & DDR5 Channel Diagnostics

Isolating transient correctable memory errors from persistent channel degradation across multi-socket NUMA topologies.

Operational Context:

When memory error rates exceed baseline thresholds, structured isolation identifies whether the issue stems from socket seating, DIMM trace degradation, or thermal micro-swings.

Investigation Sequence:

  1. Review BMC System Event Logs (SEL) for specific socket and channel DIMM slot designations.
  2. Check memory temperature telemetry to ensure DIMMs operate within safe thermal thresholds.
  3. Execute a cold boot memory retraining sequence to re-calibrate signal timing across DDR5 channels.

Diagnostics & Health

PCIe Gen 5 Link Degradation & Lane Recovery

Diagnosing accelerator slots or NVMe risers that fail to negotiate full x16 or x8 PCIe Gen 5 link widths.

Operational Context:

Physical contamination, connector seating, or power rail droop can cause high-speed PCIe links to negotiate down to lower generation speeds or degraded lane widths.

Investigation Sequence:

  1. Inspect OS link telemetry (e.g. lspci -vvv) to verify current Link Speed and Link Width status.
  2. Inspect physical gold finger contacts on accelerator cards and riser slots for debris.
  3. Verify that 12V auxiliary power feeds deliver stable voltage under peak accelerator draw.

Telemetry & Monitoring

RoCEv2 Fabric Telemetry & Packet Loss Isolation

Monitoring RDMA over Converged Ethernet networks for buffer overflow, PFC pause storms, and dropped frame indicators.

Operational Context:

Disaggregated NVMe-oF storage arrays require lossless or near-lossless network fabrics to maintain single-digit microsecond access profiles.

Investigation Sequence:

  1. Query switch port counters for Priority Flow Control (PFC) pause frames and ECN congestion marks.
  2. Verify MTU configuration consistency (Jumbo Frames 9000 MTU) across all host NICs and switch interfaces.
  3. Inspect optical transceiver receive power levels (Rx dBm) to rule out cable attenuation.

Thermal & Maintenance

Thermal Management & Static Pressure Maintenance

Best practices for maintaining laminar airflow, static chassis pressure, and fan duty efficiency in dense rack installations.

Operational Context:

High-density compute and accelerator platforms require balanced static pressure to prevent hot air recirculation within the chassis envelope.

Investigation Sequence:

  1. Ensure all unused PCIe slot covers and drive bay blanks are firmly installed to maintain internal air velocity.
  2. Inspect front air intake grilles for dust accumulation and clean filters without halting operations.
  3. Audit ambient server room supply temperatures and hot-aisle containment seals.
