Using the Long-Distance Option
ServerNet Cluster 6780 Planning and Installation Guide—527301-005

Software Requirements for Three-Zone Long-
Distance Topologies
Software Requirements for Three-Zone Long-
Distance Topologies
On all NonStop S-series servers in a cluster that uses the long-distance option in a
three-zone 6780 ServerNet Cluster topology, you must install:
•
The G06.22 or a later RVU.
•
T0502AAQ or a later SPR. T0502AAQ is an unrestricted SPR included with the
G06.28 RVU. T0502AAQ can also be ordered separately and installed on previous
RVUs such as G06.22.
•
The T2790AAC configuration image for the 6780 switch or a superseding SPR.
T2790AAC is available only as a restricted SPR.
Table G-2 lists the minimum G-series software that supports the long-distance option in
three-zone topologies. (The same software also supports long-distance two-zone
topologies, superseding the software in Table G-1.) Except for the T2790AAC switch
configuration image and the T0502AAQ SPR, all of these software products are part of
the G06.22 RVU. Additional requirements apply if the cluster contains HP NonStop
NS-Series servers in addition to HP NonStop S-Series Servers. For more details,
please refer to the ServerNet Cluster Supplement for NonStop NS-Series Servers.
Restrictions
The numeric selector settings shown in Table G-3 are optimized for zone-to-zone links
between 5 and 15 km. Configuring a ServerNet cluster with the required long-distance
option software and the numeric selector settings shown in Table G-3, but with actual
Table G-2. Software That Supports the Long-Distance Option in Three-Zone
Topologies
Product Product Version Update (PVU)
NonStop Kernel T9050APF
SANMAN T0502AAQ
SNETMON/MSGMON T0294AAM
6780 switch firmware T2789AAC
6780 switch FPGA T2819AAB
6780 switch configuration T2790AAC (restricted SPR)
Note. Installing these components separately on an RVU earlier than G06.22 is not
recommended. All nodes of a cluster that uses the long-distance option must be running
G06.22 or later.
