Considering availability, install adapters of the same type in slots of different I/O domains,
drawers, fanouts, and resource groups (for RoCE Express and zEDC Express). The next
sections describe more information about achieving a highly available configuration.
G.3 Native PCIe feature definitions
During the ordering process of the native PCIe adapters, such as the zEDC Express and
10GbE RoCE Express features, features of the same type are evenly spread across two
resource groups (resource group 1 and resource group 2) for availability and serviceability.
Figure G-2 shows a sample PCHID report of a z13s configuration with four zEDC Express
features and four 10GbE RoCE Express features.

Although Flash Express features are counted as native PCIe cards for the total number
of Native PCIe features, they are not part of any resource group.
򐂰 The Flash Express features are not defined by using the input/output configuration data
set (IOCDS).
