## Questions & Answers

**Q: Does this come with half-height, full-height or both brackets?**
A: The ones I received came with both brackets.

**Q: Are the slots qsfp or sfp+?**
A: They can support 10Gbps (sfp) and 25Gbps with SFP-128 cables that I use to connect server to Synology NAS (both with this Mellanox card).  I don't believe that they support qsfp because I believe that would be 100Gbps (I believe you have to move up to the ConnectX-5 card for that).

**Q: Can this card be installed in a "generic" server or only in an OCP system?**
A: They can be installed in "generic" server if it has required slots.
