NonStop Networking Overview

On NonStop NS-series systems, ServerNet wide area network (SWAN) concentrators use TCP/IP
to connect through the G4SA or CLIM, through Ethernet ports in the VIO enclosure or through other
Ethernet adapters in a NonStop S-series I/O enclosure. On NonStop BladeSystems, SWAN
concentrators connect through the CLIM or G4SA. On NonStop NS2000, NS2100, and
NS2200-series systems, SWAN concentrators connect through the VIO. AWAN is not supported
on NonStop NS2000, NS2100, and NonStop NS2200-series systems.
Products that Interconnect NonStop Systems — BladeCluster Solution
The BladeCluster Solution is comprised of network topologies that interconnect NonStop
BladeSystems and NonStop NS16000 series systems as nodes, which can also cluster with
6770/6780 ServerNet clusters. These interconnected nodes use ServerNet to pass information
from node–to–node functioning as one large processing entity. The BladeCluster Solution offers
five network topologies:
• BladeCluster/BladeSystem Solution (all BladeSystems)
• BladeCluster/NonStop NS16000 Series Solution (all Non Stop NS16000 series systems)
• BladeCluster/Mixed System Solution (NonStop BladeSystems and NS16000 series systems)
• BladeCluster/6700 Series Solution (BladeCluster clustered with 6770/6780 ServerNet Cluster)
• BladeCluster/Multi-Zone Solution (Up to 3 zones and up to 24 nodes -- short-haul and long-haul
distance options)
To support the BladeCluster Solution topologies, each BladeCluster node is connected along each
of two ServerNet fabrics via 2-way multilane ServerNet 3 links (unless configured for ServerNet 2
in interzone distances greater than 25 km).
The Multi-Zone long-haul topology offers distance options of either 25 km, 50 km, or 65 km.
Hardware requirements for the BladeCluster Solution include specific switches for BladeCluster
(ServerNet switch for BladeCluster and Processor Switch for BladeCluster) and 1 Advanced Cluster
Hub (ACH) per fabric. The ACH is used to connect the X and Y fabric processor switches and
ServerNet switches in a BladeCluster topology. For the multi-zone long-haul topology, Dense
Wavelength Division Multiplexer (DWDM) third-party equipment is required.
The DWDM routes the ServerNet lanes to their appropriate zone and one to two DWDMs are
required per zone. Contact your HP reprensentative for a list of DWDMs that interoperate with the
BladeCluster Solution.
For detailed BladeCluster software and licensing requirements, refer to the BladeCluster Solution
Manual. The manual also includes detailed installation, connection, migration, and upgrade
procedures for all BladeCluster topologies.
