Each DS8900F processor complex contains multiple PCIe adapters. These adapters enable  point-to-point connectivity between CPCs, I/O enclosures, I/O adapters, and the HPFEs.  Depending on the configuration, up to seven PCIe adapters are in the DS8900F processor  complex. A DS8900F processor complex is equipped with the following PCIe adapters.: Figure 2-14 shows the PCIe adapter locations in the DS8910F CPC.  GLYPH<SM590000> The DS8910F model 993 has two single-port PCIe adapters in slots C6 and C12 GLYPH<SM590000> The DS8910F model 994 has four single-port PCIe adapters in slots C6, C8, C9 and C12. GLYPH<SM590000> The DS8950F model 996 has two different processor configuration for PCIe adapters: – 1 x 10-core CPC maximum configuration for one frame has four single-port PCIe  adapters in slots C6, C8, C9 and C12. – 2 x 10-core CPC maximum configuration for two frames has six single-port PCIe  adapters in slots C2, C4, C6, C8, C9 and C12, and one two-port PCIe adapter in slot  C3fi. Single-port PCIe adapters slots C6, C8, C9, and C12 Multi-port PCIe adapter slot C3 Single-port PCIe adapters slots C2, C4, C6, C8, C9 and C12
