OSA-Express3 10 Gigabit Ethernet SR

There are two PCIe adapters per feature. OSA-Express3 10 GbE LR is designed to support attachment to a 10 Gigabits per second (Gbps) Ethernet Local Area Network (LAN) or Ethernet switch capable of 10 Gbps. OSA- Express3 10 GbE LR supports CHPID type OSD exclu- sively. It can be deﬁ ned as a spanned channel and can be shared among LPARs within and across LCSSs.

The OSA-Express3 10 Gigabit Ethernet (GbE) short reach (SR) feature has two ports. Each port resides on a PCIe adapter and has its own channel path identiﬁ er (CHPID). There are two PCIe adapters per feature. OSA-Express3 10 GbE SR is designed to support attachment to a 10 Gigabits per second (Gbps) Ethernet Local Area Network (LAN) or Ethernet switch capable of 10 Gbps. OSA- Express3 10 GbE SR supports CHPID type OSD exclu- sively. It can be deﬁ ned as a spanned channel and can be shared among LPARs within and across LCSSs.

OSA-Express3 Gigabit Ethernet LX

The OSA-Express3 Gigabit Ethernet (GbE) long wave- length (LX) feature has four ports. Two ports reside on a PCIe adapter and share a channel path identiﬁ er (CHPID). There are two PCIe adapters per feature. Each port sup- ports attachment to a one Gigabit per second (Gbps) Eth- ernet Local Area Network (LAN). OSA-Express3 GbE LX supports CHPID types OSD and OSN. It can be deﬁ ned as a spanned channel and can be shared among LPARs within and across LCSSs.

OSA-Express3 Gigabit Ethernet SX

The OSA-Express3 Gigabit Ethernet (GbE) short wave- length (SX) feature has four ports. Two ports reside on a PCIe adapter and share a channel path identiﬁ er (CHPID). There are two PCIe adapters per feature. Each port sup-

ports attachment to a one Gigabit per second (Gbps) Eth- ernet Local Area Network (LAN). OSA-Express3 GbE SX supports CHPID types OSD and OSN. It can be deﬁ ned as a spanned channel and can be shared among LPARs within and across LCSSs.

Four-port exploitation on OSA-Express3 GbE SX and LX

For the operating system to recognize all four ports on an OSA-Express3 Gigabit Ethernet feature, a new release and/or PTF is required. If software updates are not applied, only two of the four ports will be “visible” to the operating system.

Activating all four ports on an OSA-Express3 feature pro- vides you with more physical connectivity to service the network and reduces the number of required resources (I/O slots, I/O cages, fewer CHPIDs to deﬁ ne and manage).

Four-port exploitation is supported by z/OS, z/VM, z/VSE, z/TPF, and Linux on System z.

OSA-Express3 1000BASE-T Ethernet

The OSA-Express3 1000BASE-T Ethernet feature has four ports. Two ports reside on a PCIe adapter and share a channel path identiﬁ er (CHPID). There are two PCIe adapters per feature. Each port supports attachment to either a 10BASE-T (10 Mbps), 100BASE-TX (100 Mbps), or 1000BASE-T (1000 Mbps or 1 Gbps) Ethernet Local Area Network (LAN). The feature supports auto-negotiation and automatically adjusts to 10, 100, or 1000 Mbps, depending upon the LAN. When the feature is set to autonegotiate, the target device must also be set to autonegotiate. The feature supports the following settings: 10 Mbps half or full duplex, 100 Mbps half or full duplex, 1000 Mbps (1 Gbps) full duplex. OSA-Express3 1000BASE-T Ethernet supports CHPID types OSC, OSD, OSE, and OSN. It can be deﬁ ned as a spanned channel and can be shared among LPARs within and across LCSSs.
