Processor Drawer Concept - IBM z13s Technical Manual

PCIe I/O infrastructure
The PCIe I/O infrastructure uses the PCIe fanout to connect to the PCIe I/O drawer, which
can contain the following features:
FICON Express16S, a two port card (long wavelength (LX) or short wavelength (SX)) and
two physical channel IDs (PCHIDs)
FICON Express8S (two port card, LX or SX, and two PCHIDs)
Open Systems Adapter (OSA)-Express5S features:
– OSA-Express5S 10 Gb Ethernet (one port card, Long Reach (LR) or Short Reach
(SR), and one PCHID)
– OSA-Express5S Gb Ethernet (two port card, LX or SX, and one PCHID)
– OSA-Express5S 1000BASE-T Ethernet (two port card, RJ-45, and one PCHID)
OSA-Express4S features (only for a carry-forward MES):
– OSA-Express4S 10 Gb Ethernet (one port card, LR or SR, and one PCHID)
– OSA-Express4S Gb Ethernet (two port card, LX or SX, and one PCHID)
– OSA-Express4S 1000BASE-T Ethernet (two port card, RJ-45, and one PCHID)
Crypto Express5S feature. Each feature holds one PCI Express cryptographic adapter.
Each adapter can be configured during installation as a Secure IBM Common
Cryptographic Architecture (CCA) coprocessor, as a Secure IBM Enterprise Public Key
Cryptography Standards (PKCS) #11 (EP11) coprocessor, or as an accelerator.
Flash Express. Each Flash Express feature occupies two slots in the PCIe I/O Drawer, but
does not have a CHPID type. Logical partitions (LPARs) in all channel subsystems (CSSs)
have access to the features.
10 GbE Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE)
Express. It has a 2-port card, and up to 31 LPARS can share a physical adapter.
zEnterprise Data Compression (zEDC) Express. The zEDC Express feature occupies one
slot in the PCIe I/O Drawer, and one PCHID. Up to 15 partitions can share the feature
concurrently.
InfiniBand I/O infrastructure
InfiniBand I/O infrastructure uses the HCA2-C fanout to connect to I/O drawers. The I/O
drawers can contain only these features:
FICON Express8 cards, maximum quantity eight. Each card has four ports, LX or SX, and
four PCHIDs.

2.2 Processor drawer concept

The z13s CPC drawer contains up to six SCMs, memory, symmetric multiprocessor (SMP)
connectivity, and connectors to support:
PCIe I/O drawers (through PCIe fanout hubs)
I/O drawers through InfiniBand fanout features
Coupling links fanouts
