SWAN 2 Concentrator Connections
In Example 1-1, specifying 8192 datapages provides 8 megabytes memory to
WANMGR, which allows configuration of approximately 750 to 800 SWAN 2
concentrators. For further information on configuring a SWAN 2 concentrator, refer to
the WAN Subsystem Configuration and Management Manual.
SWAN 2 Concentrator Connections
SWAN 2 concentrator connections provide redundant ServerNet X and Y fabrics to the
Ethernet adapters. If one ServerNet fabric fails, the Ethernet adapter can still be
accessed using the remaining ServerNet fabric.
HP recommends configuring a SWAN 2 concentrator to connect to Ethernet ports on
two E4SAs, FESAs, GESAs, or G4SAs; this type of configuration provides more
fault-tolerance for the IOPs that use the lines on the SWAN 2 concentrator.
SWAN 2 concentrator connections include:
•
Integrity NonStop BladeSystem connection
•
Integrity NonStop NS-series server connection
•
NonStop S-series server connection
•
NonStop S-series I/O enclosure attached to an Integrity NonStop NS-series server
connection
Integrity NonStop BladeSystem Connection
The SWAN 2 concentrator connects to a NonStop BladeSystem using fault-tolerant
10/100 Base-T connections provided by the G4SAs installed in the BladeSystem’s
IOAM enclosure. G4SAs, CCSAs, and TRSAs are the only ServerNet adapters that
can connect to a BladeSystem. For more information, see the NonStop Networking
Overview or the NonStop BladeSystem Planning Guide.
Integrity NonStop NS-Series Connection
The SWAN 2 concentrator connects to the Integrity NonStop NS-series server using
fault-tolerant 10/100 Base-T connections provided by one or two G4SAs installed in an
IOAM enclosure.
