| Specifications | PCIe x8 Slot: The host interface where the AIC will be connected. Supports PCIe 4.0 speeds (16 GT/s per lane) for higher bandwidth. PCIe ReTimer: A ReTimer is used to extend signal integrity and reduce signal degradation over longer traces or cables. are essential for maintaining PCIe 4.0 stability, especially when using SlimSAS connections, which tend to be prone to signal loss over distance. Common ReTimers: IDT 89HT0832P or Astera Labs Aries for PCIe 4.0. SlimSAS 8i Connector: SlimSAS 8i carries 8 lanes (x8) of PCIe or NVMe. "8i" refers to 8 lanes, while "4i" carries 4 lanes. The x4 datalink width limitation means the ReTimer or the AIC itself will negotiate only 4 lanes of PCIe traffic, effectively using only half the available bandwidth. |
