| H A D | vpd-collection.md | 1 # VPD collection app on OpenBMC
9 On OpenBMC, Vital Product Data (VPD) collection is limited to only one or two
11 systems, the BMC also supports just one VPD format, the [OpenPower VPD] [1]
13 VPD, which the BMC currently does not support. Certain FRUs also have keyword
14 format VPD.
16 The BMC requires to read VPD for all FRUs for several reasons:
18 - Some of the VPD information such as FRU part number, serial number need to be
26 - There are use cases for the BMC to send VPD data to the host
28 get VPD that is not directly accessible to it.
30 The VPD data itself may reside on an EEPROM (typical) or may be synthesized out
