Abstract

This invention is a method and procedure for translation of vital product data (VPD) from the format used by one original equipment manufacturer (OEM) to the format of a consumer device. It is able to take the known format of an OEM device and translate it into an expected format for the consumer device.

Method and Procedure for the Translation of Vital Product Data

Disclosed is a method and procedure for translation of vital product data (VPD) from the format used by one original equipment manufacturer (OEM) to the format of a consumer device. For the purposes of explanation, the design and implementation specific to the upcoming IBM DS4000 Storage Blade (RCB) will be used.

VPD is used for various purposes in different hardware applications. In some applications, VPD is an extensive and dynamic set of several data blocks written to a memory device. In these sophisticated VPD implementations, dynamic information about the VPD-carrying device may be communicated to the consumer device, and vice-versa via the VPD dynamic blocks. In some cases OEM devices designed to fit within a larger consumer device or chassis sometimes have different schemes for the memory space (offsets, endian format, etc). An RCB has several VPD devices onboard as illustrated in Figure 1 below.

processor for the mainboard. The BMC communicates to the BladeCenter Management Module (MM) which serves as the service processor for the entire BladeCenter chassis. The MM is illustrated in Figure 1 as the outboard entity connected by a dotted line to the BMC. The IBM BladeCenter environment has a very sophisticated VPD scheme in place to enable blades to know about the blade center environment and to enable the MM to know the blade manufacturing characteristics and environmental capabilities to determine if the blade is supported in the chassis. In previous blade designs, the system board was designed by IBM. The OEM relationship used to create the RCB has turned up some complications. One of these is the factor th...
