Q: Why are certain SAI implementations only distributed in binary form?

Q: Which hardware platforms are you running OPX Base on?

A: The current release of OPX Base supports Dell S6000-ON devices only. Future implementations will support various devices, platforms, and ASIC vendors.

---

Q: What is your testing strategy for multiple ASIC vendors to check in the code?

A: We have an initial test framework which is based on Ansible test suites. ASIC vendors have the ability to take OpenSwitch itself, run it on their platforms, and run the test suite that we're building. We're currently working on testing and qualification labs for future releases.

---

Q: Does OPX Base support ToR as well as modular switches?

A: OPX Base supports both ToR and modular switches using the CPS layer. The CPS layer allows you to configure a group of switches together, and then talk to them all through the CPS layer (as if they were local). Although the S6000-ON platform supports it, OPX Base does not currently support fabric in this release.

---

Q: Do you recommend using the Linux standard drivers and interfaces in the SDI layer or are they vendor provided?

A: We do recommend you use the vendor's drivers that currently exist in Linux today. We don't recommend system vendors or ODM platforms to provide kernel-level modules or kernel modifications for that support.
