I noticed that several HighPoint U.2/U.3 NVMe AICs provide four physical ports, yet support up to 8 SSDs. The available cables accessories appear to support 2 drives each. Is it possible to get full performance from both SSDs attached to the same cable?

This is possible. Each of the card’s four ports can provide up to x8 lanes.
Cables with two connectors can provide up to x4 lanes per device connection
Cables with a single device connector (such as SFF-8643 or SFF-8654) provide x8 lanes
This is true for all of our U.2/U.3 cable accessories:
- SFF-8643 to SFF-8639 (8643-8639-100 & 8643-8639-50 cables)
- SFF-8643 to SFF-8643 (8643-8643-060 cable)
- SFF-8643 to SFF-8611 (OLX4-8643-061)
- SFF-8654 to SFF-8654 (8654-8654-110 cable)
- SFF-8654 to SFF-8639 (TS8i-8639-060 cable)
- SFF-8654 to SFF-8643 (8654-8643-210 cable)
- SFF-8654 to SFF-8611 (8654-8611-205 cable)
- SFF-8654 to MCIO (8654-MCIO-110 cable)
