iSeries Architecture: Fundamental Strength of the iSeries
28
iSeries Handbook
This new bus structure of HSL provides:
• Performance improvements and future system growth
– 1 GB/sec technology
– 700 MB/sec maximum deliverable capacity running full duplex
• Simplified implementation
– Loop technology for redundancy
– Multiple towers per loop
– Migration tower attachment to support SPD I/O towers and PCI expansion
Towers (#5065/#5066)
• A homogeneous HSL network with V5R1 HSL adapters
– Simple HSL Clusters (two iSeries)
– xSeries for iSeries HSL connectivity
– Switchable HSL connected tower with IASP
For further details, see the product sections within this Handbook or
AS/400e to iSeries 400

Clustering with Switchable DASD and IASP
OS/400 V5R1 and HSL OptiConnect provide switchable disk capability. Independent Auxiliary
Storage Pools and switched disk clusters provide the ability to access content on a set of disk
units from a second system. Support for both planned and unplanned outages is improved
when the system currently using a switchable disk experiences an outage. Operations are
continued on a system even when an isolated controller or disk unit fails.
Data availability is improved with Independent Auxiliary Storage Pools or switched disk
clustering. Within a cluster, users can be switched to an alternate node in the cluster (another
iSeries server) upon an outage. Integrated file system data residing in an IASP can be
switched to another iSeries server without an IPL. This enables one iSeries to take over data
and I/O controller in a disk tower from another iSeries.
Option 41 of OS/400 V5R1 is required to enable independent ASPs and switched disk clusters. It
is a chargeable feature.
The primary function in the early stages of clustering is to offer coverage for planned
upgrades and maintenance on the production system without affecting users accessing data
from the switched disk towers, for the User Defined File System only. Cluster management
middleware software, shipped as part of OS/400 option 41, manages the switchover. For high
availability purposes, it ensures that no two systems access the disks (data) at the same
time.
