4769 on x64 Servers

This page provides information on the IBM 4769 HSM on x64 servers.

This page contains charts that show x64 servers, operating systems, and CCA versions for the IBM 4769. For x64 servers, the IBM 4769 is ordered as an IBM Z® machine type-model 4769-001. The charts do not imply that the operating systems will work under all combinations of hardware and software.

Potential DIMM Collision

Certain x86 systems do not boot when the 4769 adapter is plugged in to one or more PCIe slots. System boot is frequently accompanied by a system warning sound that indicates memory issues. Affected systems will boot properly after the adapter has been unplugged from the PCIe slot.

In a system that does not populate all DIMM slots, a possible workaround can be attempted by moving DIMM modules to different slots.

For more information on the DIMM collision, refer to DIMM collision full explanation (PDF, 107 KB).

Servers IBM has tested to work:

System x3650 M5
ThinkSystem SR550

The 4769 can be used in any x64 server that has at least one PCIe slot capable of accepting a half-height, half-length PCIe card and that meets the power and environmental requirements specified in the Environmental requirements section of the IBM 4769 Data Sheet (PDF, 413 KB). The compatibility chart of supported operating systems above lists the operating systems that have been tested with and are supported by IBM with CCA releases on the IBM 4769.

Note: Using an IBM 4769 in a server that does not meet these requirements voids the warranty.
