IBM Systems Director VMControl 2.1Image Manager Overview

Discover existing image repositories and import external, standards-based images into your repositories as virtual appliances.

Capture a running virtual server that is configured just the way you want, complete with guest operating system, running applications, and virtual server definition. When you capture the virtual server, a virtual appliance is created in one of your image repositories.

Import virtual appliance packages that exist in the Open Virtualization Format (OVF) from the Internet or other external sources. After the virtual appliance packages are imported, you can deploy them within your data center.

Deploy virtual appliances quickly to create new virtual servers that meet the demands of your ever-changing business needs.

Systems Director VMControl Image Manager supports deploying virtual appliances to the following platforms:

– PowerVM virtual appliances on IBM® Power Systems® servers (POWER5™ and POWER6™) that are managed by Hardware Management Console or Integrated Virtualization Manager

– Linux® virtual appliances on System z® systems running on the z/VM® hypervisor

Relocate Virtual Servers between Hosts within the Pool- Determine best host placement within the pool- Supports single virtual servers and host evacuation

Move virtual servers away from a failing host system.- Automate relocation and placement of virtual servers in response to

predicted host system failures with no disruption.

Restart virtual servers when a host system fails.- Automate remote restart and placement of virtual servers in response

to host system failures with minimal disruption.- From a checkpoint in the future.

Resilience policy associated with the workload- Provide workload resilience – yes/no- Enables host system monitoring for failures and predictive failures- Automates recovery action based on desire level of automation

Automation policy associated with the workload- Automate = Advise / Automate- Advise – VMControl recommends actions and requires confirmation- Automate – VMControl automates actions
