VIOS Shared Storage Pool and thin provisioning
I wondered why IBM® Power Systems™ does not have the snapshot and thin-provisioning features that can make the life of a System Administrator much easier when there is a need to upgrade or maintain efficiency. Finally, I found it in Virtual I/O Server (VIOS) Shared Storage Pool, which I have detailed in this article.
Multi-disk management for IBM Systems Director VMControl: Part 3
IBM® Systems Director is a platform management solution that is used to manage physical and virtual systems. IBM Systems Director provides systems management personnel with a single pane of glass, helping reduce IT management complexity and cost.
Stack-based breadth-first search tree traversal
This article explains the traditional breadth-first search (BFS) that has drawbacks in terms of extra space required by the queue data structure. If a tree has multiple children and is a balanced tree, then the queue size would grow exponentially and could cause serious memory threats.
Considerations in software design for multi-core multiprocessor architectures
Today's chip multithreaded,multi-core,multiprocessor systems provide software designers a great opportunity to achieve faster and higher throughput.However,there are a few key design considerations, if ignored,could result in hard-to-find performance issues and scalability bottlenecks.
Multi-disk management for IBM Systems Director VMControl: Part 2
IBM Systems Director is a platform management solution that is used to manage physical and virtual systems. IBM Systems Director provides systems management personnel with a single pane of glass, helping reduce IT management complexity and cost.
PowerVM configuration and scaling with WebSphere Portal
This article describes a series of performance benchmarks that demonstrate the scaling properties of an IBM PowerVM® virtual machine running IBM WebSphere® Portal on the IBM AIX® operating system.
Multi-disk management for IBM Systems Director VMControl: Part 1
IBM® Systems Director is a platform management solution that is used to manage physical and virtual systems. IBM Systems Director provides systems management personnel with a single pane of glass, helping reduce IT management complexity and cost.
Setting up the IBM AIX server as a router (static routing)
Routing is the process of moving a packet of data from source to destination. Static routing uses manually added routes whereas dynamic routing uses dynamic routes. This article explains how to set up an IBM® AIX® server as a router to communicate with private and public networks by using static routing.
Shared Ethernet Adapter configuration with two networks
This tutorial describes how to configure two different networks using Virtual I/O Server (VIOS) with high availability, redundancy, and load sharing. With this architecture, VIOS and logical partitions (LPARs) can be accessed from two completely different networks and both networks can be used for different purposes.
The troubleshooter's guide for managing storage using IBM Systems Director
The purpose of this article is to document the troubleshooting methodologies and the best practices to be followed while managing the storage component and also provide the information about what needs to be verified in an entity, such as IBM® Systems Director, LSI, NetApp Eagle provider.
