FAQs

Q: What fabric interconnects are supported?
A: Use with compatible 40Gb-capable fabric interconnects as documented for your UCS domain and software release.

Q: Does it support mixed environments with 10Gb?
A: Uplink speed and optics must match the fabric interconnect capabilities; migration from 10Gb requires appropriate FI hardware and UCS Manager version.

Q: Is there any on-module switching?
A: No. It operates as a fabric extender; switching and policy occur at the fabric interconnect.

Q: Are QSFP optics included?
A: Optics are typically purchased separately unless specified by the bundle SKU.

Q: Can I run dual fabrics for redundancy?
A: Yes. Deploy one IOM per fabric (A and B) for high availability.
