HiPath 8000

The HiPath 8000 is an IP softswitch for large and very large companies up to 100,000 users.

Performance features

The HiPath 8000 is a native SIP-based Real-Time IP System that is ideal for both large and very large enterprises and for managed service providers. Designed for data center deployment, HiPath 8000 fits perfectly into the IT world. It allows companies to simply and cost-effectively integrate converged voice, multi-media and multi-modal services.

System architecture

• Software: Linux based
• Hardware: IBM e-Series with two Intel Xeon CPUs

Applications and Devices

The following devices can be connected to HiPath 8000:

• OpenStage SIP phones:
  • OpenStage 20, OpenStage 40, OpenStage 60 and OpenStage 80
• optiPoint 410/420 S phones:
  • optiPoint 410 entry S, optiPoint 410 economy S, optiPoint 410 economy plus S, optiPoint 410 standard S and optiPoint 410 advance S
  • optiPoint 420 economy S, optiPoint 420 economy plus S, optiPoint 420 standard S and optiPoint 420 advance S
• optiPoint WL2 professional S
• optiPoint 150 S
• optiClient 130 S

Administration and Service

Networking scenarios

Networking Scenarios are discussed in Detail in the Edoku HiPath 8000 Network Planning Guide (non-public). However, note, that at least the VLAN design will be changed soon. Here, we document the new proposal.

Flat VLAN Design

In a flat VLAN design, the VLANs are extended from one HiPath 8000 node to the other. In case of failure of an active node, the IP addresses of this node is transfered to the other. A drawback of this design is, that high redundancy can only be achieved when using redundant layer 2 networks with the Spanning Tree Protocol being used to remove loops from the network. However, note, that Spanning Tree problems can lead to 100% network load and to the unavailibility of both HiPath 8000 nodes. Also, Spanning Tree problems are easy to troubleshoot. We recommend to a Split Subnet design with a Spanning Tree less design if possible.

Split Subnets

With the Split Subnets design, all VLANs except the cluster interconnect are local to one HiPath 8000 node only. See below a proposal of the VLAN design, which can not be found in the Edoku yet (version 2.2, issue 2):

Loop-less (Spanning Tree-less) VLAN Design for a HiPath 8000 Split Subnet Design.

Note, that the Routers SHOULD NOT be attached redundantly. If e.g. Router 1 is attached to Switch 1 and Switch 2 with VLANs 2, 4 and 6 on both links, a layer 2 loop would be created (Router 1 -- Switch 1 -- Switch 2 -- Router 1). To resolve this, we will need Spanning Tree on the Switches as well as on the Router. However, the need for Spanning Tree is to be avoided and Spanning Tree should only be switched on the Switches for decreasing the impact on any erroneous miscabling.
