ABSTRACT OF PROBLEM
___________________
OSA-Express support.
COMMENTS ON PROBLEM
___________________
TCP/IP native stack support (APAR PJ26683) enabled the TPF
system to directly connect to IP networks. PJ26683 included a
full socket layer, the protocol layers (TCP and UDP), the IP
layer, and the IP over CDLC link layer. Open Systems Adapter
(OSA) is a card that resides in the IBM CMOS processors. OSA
allows S/390 hosts to connect to IP networks directly without
the need for front-end channel-attached routers. OSA-Express is
the third generation of OSA and is available on IBM G5
processors and above. OSA-Express has 3 important features that
make it highly desirable in a TPF environment:
1. Connects to high bandwidth TCP/IP networks, specifically
gigabit Ethernet (GbE)
2. Uses the Queued Direct I/O (QDIO) link layer to communicate
between the host and OSA card. Older OSA cards like OSA/2
use standard channel programs to transfer data between the
host and OSA card. QDIO enables the host and OSA card to
share memory, which eliminates the need for channel programs
to exchange data. The result is much higher throughput and
performance.
3. An OSA-Express card can be configured by the host. Older
OSA cards such as OSA/2 required the OSA/SF feature to
configure the card. OSA/SF is not required to use
OSA-Express on TPF.
With the IP over CDLC link layer, one TPF IP address can be
mapped across multiple IBM 374x IP routers, therefore, an IP
router is not a single point of failure. To eliminate single
points of failure in the OSA-Express environment, virtual IP
address (VIPA) support is needed so that a TPF IP address can be
moved from one OSA-Express card to another if the card fails or
if the GbE switch connected to the card fails.
In a TPF loosely coupled complex, there needs to be a way to
move TCP/IP traffic from one processor to another processor in
the complex. This is necessary when there is a planned or
unplanned outage of a processor, a new processor is brought into
the complex, or when the workload is not balanced across the
complex.
SOLUTION
________
TPF now supports the OSA-Express card. An OSA-Express card
comes with one network adapter. The only OSA-Express adapter
supported by the TPF system is gigabit Ethernet (GbE). The
other adapter types (currently fast Ethernet and ATM-155) are
not supported by TPF. A TPF processor can connect to multiple
OSA-Express cards concurrently. An OSA-Express card can be
shared by TPF and other LPARs in the CEC, including other TPF
systems and other S/390 hosts.
The QDIO link layer has been implemented in the TPF system and
is used to communicate with the OSA-Express card. This means
that there are now 2 link layers with TPF TCP/IP native stack
support; IP over CDLC and QDIO. You can have IP over CDLC con-
nections and OSA-Express connections active at the same time.
The IP address of TPF across a CDLC connection is different than
the IP address of TPF across an OSA-Express connection. The TPF
IP address determines which type of connection to use. A TPF
socket server application that binds to all IP addresses (binds
to IP_ANY) is bound to all TCP/IP native stack interfaces,
including all CDLC connections and all OSA-Express connections.
In other words, one TPF server application can receive traffic
from CDLC and from OSA-Express connections.
VIPAs are now supported across OSA-Express connections. When
you define an OSA-Express connection to a TPF processor, you can
define an alternate OSA-Express connection. If an OSA-Express
connection fails, VIPAs defined to that connection are automat-
ically swung to the alternate OSA-Express connection. This
enables sockets to survive the failure of an OSA-Express card,
the GbE switch, or the Ethernet itself. You can swing VIPAs
manually from one OSA-Express connection to another on the same
processor using the ZOSAE SWING functional message. A TPF
processor has a different real IP address for each of its
OSA-Express connections. If an OSA-Express connection fails,
all sockets using the real IP address of TPF across that con-
nection will also fail. In a production TPF environment, socket
applications should use VIPAs rather than real IP addresses to
eliminate single points of failure.
TPF supports 2 types of VIPAs; static and movable. A given
static VIPA always resides on the same TPF processor. A static
VIPA can be swung from one OSA-Express connection to another,
but always on the same TPF processor. Static VIPAs enable
remote clients to access processor-unique TPF applications. A
movable VIPA can be defined on all or a subset of the processors
in the loosely-coupled complex; however, a movable VIPA is only
active on one TPF processor at any point in time. A movable
VIPA can be moved from one TPF processor to another in the
complex manually using the ZVIPA MOVE functional message, or
automatically when a processor fails (if the UVIP user exit
indicates that the VIPA should be moved). Movable VIPAs allow
you to balance TCP/IP connections with TPF processor shared
applications.
The way that VIPAs work is that a VIPA is not permanently tied
to a specific physical network. A TPF VIPA can be moved from
one ethernet to another (from one OSA-Express connection to
another). This is done using Routing Information Protocol
(RIP). TPF now supports a subset of RIP version 2 and uses RIP
to inform the IP routers of the current path (OSA-Express con-
nection) to use to reach a given VIPA. This is the only use of
RIP in TPF. Because TPF is an IP host and not an IP router, TPF
does not maintain full routing tables or save routing informa-
tion received in RIP messages from IP routers. An OSA-Express
card connects to a GbE switch and IP routers are also connected
to that switch. You must have RIP enabled on those IP routers
on the interfaces between the routers and the switch to use VIPA
support in TPF.

Migration Considerations
========================
Changes to Communications
-------------------------
This support requires an IBM G5 processor or higher with
OSA-Express cards using GbE adapters that are at microcode level
4.08 or higher.
TPF running as VM guest requires VM/ESA 2.4 or higher to use
OSA-Express support.
Refer to the Migration Guide for additional information.
