Frequently Asked Questions
What is the difference between ST0 and other SKUs?
The ST0 (Standard Enterprise) variant is enterprise-optimized, offering pre-validated compatibility with major server OEMs, global certifications, and extended lifecycle support policy.
Can I split the single OSFP port into multiple lower-speed connections?
Yes. The C8180 supports port splitting to 2x 400GbE or 8x 100GbE, providing flexible deployment options.
What are the key security features?
Secure Boot, Hardware Root of Trust, Flash Encryption, Device Attestation (SPDM 1.1), and Inline Crypto (IPsec/MACsec/PSP).
Buyer Checklist
- Confirm server has PCIe 6.0/5.0 x16 slot with sufficient power and cooling
- Select OSFP optical modules or DAC/AOC compatible with 800G/400G PAM4 signaling
- Verify operating system and driver support
- Plan network topology for InfiniBand or Ethernet fabric
- Check for RDMA and GPUDirect enablement in BIOS and software stack
