BladeCluster Solution Manual

NOTE: For a list of supported DWDMs, contact your HP representative.
For information about connecting these multi-zone topologies, refer to “Connections to
BladeCluster/Multi-Zone Solution Topologies” (page 63).
Multi-Zone Configuration Options
There are two BladeCluster/Multi-zone configuration options:
• The first option is a fault-tolerant, high-availability configuration. The high-availability
configuration option splits the anchor node's inter-zone connections between two c7000
enclosures. The X-fabric inter-zone connections are made from the X-fabric ServerNet switch
in the first c7000 enclosure (Group 100, Module 2), while the Y-fabric inter-zone connections
are made from the Y-fabric ServerNet switch in the second c7000 enclosure (Group 101,
Module 3).
NOTE: The high-availability configuration requires a minimum of two c7000 enclosures and
four ServerNet switches (two of these switches must be the BladeSystem ServerNet High IO,
BladeCluster switches). In this configuration all the Y-fabric cluster connections: intra-zone,
inter-zone, and 6700 series ServerNet clusters (if present) are made from the Y-fabric switch
in group 101.
• The second configuration option offers one c7000 enclosure where all inter-zone connections
to the BladeSystem anchor nodes are made from two ServerNet switches, one each for the X
and Y fabrics, in Group 100 of each anchor node.
Important Considerations for Multi-Zone Topologies
• H06.23 and J06.12 and later RVUs are required for all nodes connected to a
BladeCluster/Multizone Solution with distances greater than 25 km.
• For a long-haul topology, you use one of these SPRs, depending on the distance option:
T0999H01 is required only in anchor nodes of multi-zone BladeCluster topologies with
interzone distances up to 25 Km.
◦
◦ T0930H01 is required only in anchor nodes of multi-zone BladeCluster topologies with
interzone distances greater than 25 km.
• For all nodes connected to a long-haul multi-zone topology, the BCZ1Z2DIST, BCZ1Z3DIST,
and BCZ2Z3DIST BladeCluster inter-zone distance attributes must be configured via SCF.
There are also considerations for configuring data rate speed attributes in multi-zone topologies.
In particular, the BCZ1Z2SPEED, BCZ1Z3SPEED, and BCZ2Z3SPEED attributes must be
configured in all nodes in multizone topologies with interzone distances greater than 25 km.
The SCF ALTER SUBSYS $ZZSCL and SCF INFO SUBSYS $ZZSCL commands also now support
new BladeCluster interzone speed attributes. For more information on configuring these
attributes, see “BladeCluster Inter-zone Distance Attributes” (page 63) and “BladeCluster
Inter-zone Speed Attributes” (page 64).
• The BCZ1Z2SPEED, BCZ1Z3SPEED, and BCZ2Z3SPEED attributes must also be configured
in a multi-zone BladeCluster/6700 Solution cluster (regardless of distance considerations)
when the zones are connected only along the 6700 cluster fabrics. For more details, refer to
the NOCONN option in “BladeCluster Inter-zone Speed Attributes” (page 64).
