z/OS V1R13 Communications Server hardware requirements:

IP

Communications Server provides direct LAN communication and provides for point-to-point communication over S/390 channels (ESCON and/or Block Multiplex) to several IBM and equivalent other vendor devices.
  • Direct LAN communication is provided by:
    • IBM Open Systems Adapter - Express
    • IBM Open Systems Adapter
    • IBM 3172 Interconnect Controller
    • IBM 8232 LAN Channel Station
  • Point-to-point communication over System z channels is supported with the following devices:
    • IBM RS/6000
    • IBM Channel-to-Channel Adapter
    • IBM 374X Communications Controller
    • IBM 2216 Multiaccess Connector
    • IBM Netfinity® Server
    • Cisco 7200 and 7500-series Channel Attached Routers
    • NSC Hyperchannel A220

A zEC12, z196, or z114 server is required to use the following functions:
  • OSA-Express network traffic analyzer
  • OSA-Express virtual MAC
  • QDIO diagnostic synchronization

A zEC12, z196, or z114 server is required to use the following functions:
  • Support for z/OS Communications Server for intra ensemble networks
  • OSA-Express4S QDIO IPv6 checksum and segmentation offload

A zEC12, , z196, z114, or System z10 server is required to use the following functions:
  • OSA-Express optimized latency mode
  • OSA-Express inbound workload queueing
  • Support for z/OS Communications Server for intra ensemble networks

A zEC12, , z196, z114, System z10, or System z9 server is required to use the following functions:
  • OSA-Express network traffic analyzer
  • OSA-Express virtual MAC
  • QDIO diagnostic synchronization
  • QDIO support for OSA interface isolation

A zEC12, z196, z114, System z10, System z9, z990, or z890 server is required to use the following functions:
  • ICSF encryption/decryption instructions, called crypto assist, which provide synchronous clear key support for DES, TDES, and SHA-1 algorithms for IPSEC.
  • The checksum offload of IPv4 packets enhancement. An OSA-Express with a supporting level of microcode is also required.
  • IPv4 Broadcast support for HiperSockets.
  • Segmentation Offload (Large Send). An OSA-Express with a supporting level of microcode is also required.
SNAFor communication with remote resources, one or more of the following products, or their equivalent, is required:
  • Channel-to-channel adapter
  • FICON channel-to-channel adapter
  • IBM 2216 NWays Multiaccess Connector
  • IBM 3088 Multisystem Channel Communication Unit
  • IBM 3172 Nways® Interconnect Controller
  • IBM 3174 Establishment Controller
  • IBM 3720, 3725, or 3745 Communication Controller
  • IBM 3746 Nways Multiprotocol Controller
  • IBM Cross-System Coupling Facility (XCF)
  • IBM Enterprise System Connection (ESCON) channel
  • IBM Open Systems Adapter-Express
  • IBM Open Systems Adapter

APPN over native ATM requires:
  • OSA-2 adapter
  • ATM external private or public equipment, for example, IBM 8260 NWays Multiprotocol Intelligent Switching Hub

Multinode Persistent Sessions support requires a coupling facility with a minimum of CFLEVEL=1.

VTAM Generic Resource support requires a coupling facility with a minimum of CFLEVEL=0.

VTAM cryptographic enhancements, when used with the extended recovery facility (XRF) and Transaction Security System (TSS) family of products (4755), require 4755 Model 23 and later.

SNA triple DES (TDES) session level encryption requires a Cryptographic Coprocessor on the server.
