Scope
Internal server cables are reviewed against the platform, controller, backplane, routing constraints, and connector orientation.
Request preparation
Provide equipment identifiers, both connection points, available reference numbers, length, orientation, quantity, and photographs only when they are approved for sourcing use.
Technical parameters and selection boundaries
Published configurations differ by manufacturer and exact part number. These are selection dimensions, not one combined specification.
| Parameter | Documented example or choice | Verify for this request |
|---|---|---|
| Concrete internal breakout example | Inter-Tech article 88885640 connects one SlimSAS SFF-8654 8i interface to two MiniSAS SFF-8643 interfaces. | A connector name alone does not establish pinout, sideband routing, protocol or backplane compatibility. |
| Length and conductor size | 0.75 m and 32 AWG for article 88885640. | These values apply to that article, not every SlimSAS harness. Confirm routed distance and strain relief inside the chassis. |
| Protocol evidence boundary | The Inter-Tech sheet labels its data-transfer rate as 24 Gb/s. | It does not explain lane versus aggregate scope in the inspected sheet. Do not translate that label into a PCIe generation or guaranteed host throughput. |
| Separate PCIe cable-range example | DEREN describes its reviewed internal cable range for PCIe 4.0 / 16 GT/s signaling. | This is a separate manufacturer range, not a rating for the Inter-Tech article. Obtain the exact assembly specification. |
| Impedance is application-specific | DEREN lists 85 Ω and 100 Ω application options. | Specify the correct protocol/channel requirement. These are alternatives, not interchangeable values within one unspecified assembly. |
Standard configurations and project options
| Configuration area | Documented option | Project decision |
|---|---|---|
| Connector exit and retention | The reviewed DEREN range lists straight, right-angle and side-exit plugs, with latch and pull-tab options. | Confirm the exact drawing, connector orientation, reach to the latch and chassis clearance. Availability of a range option is not a site manufacturing promise. |
| Lane grouping and internal routing | Documented DEREN examples include SlimSAS 4X straight-to-4X straight and 8X straight-to-two-4X straight. | The selected controller, backplane and port mapping must support the assembly. Include pinout, sidebands and branch lengths in the request. |
Representative models and configurations
Examples illustrate real product variation. A listed manufacturer or model is not a statement of our stock, authorization, or confirmed availability.
| Manufacturer / series | Published configuration | Important scope |
|---|---|---|
| Inter-Tech 88885640 | SFF-8654 8i to 2×SFF-8643; 0.75 m; 32 AWG. | Exact official datasheet article, dated 30 January 2024. Its rate label needs further interpretation; no current stock or universal compatibility is implied. |
| DEREN SlimSAS 8X STR to SlimSAS (4X+4X) STR | A manufacturer-listed split configuration with two four-lane branches. | Configuration name, not a complete orderable MPN. Request a controlled drawing and exact build code. |
Applications and procurement context
- For internal server or storage routing, identify the controller, backplane and connectors at both ends, then specify lane mapping, cable length, impedance, connector exit and latch access. Keep each manufacturer example within its own documented scope.
Compatibility, current supply, lead time, origin, and acceptance documents must be confirmed for the actual order.
