TriParadigm has developed numerous virtualization policies, guidelines, standards, and procedures over several years of experience in working with these technologies. Providing a virtualization environment that can accomodate a large organization requires planning and strict adherence to policies, guidelines, standards and procedures.
One of the most difficult tasks in a virtualized environment is identification and association of resources such as virtual SCSI adapters, virtual ethernet adapters, and storage. These tasks become even more difficult in large environments where there may be dozens, if not hundreds of LPAR's on a single frame. The greatest difficulty lies in maintenance and updates of existing virtualized LPAR's where there may be hundreds of disks configured on each VIO server. The ability of the system administrator to accurately identify which virtual SCSI adapters and disks are associated with each client LPAR is critical. Misidentification can lead to corruption of data and extended outages. A rigid set of policies, guidelines, standards, and procedures can help simplify and automate these administration tasks.
In conjuction with TriParadigm's advanced usage of IBM Advanced Power virtualization (APV), our business continuity methodology is uniquely positioned for the implementation of Live Partition Mobility and Live Workload Partition Migration.
Live Partition Mobility allows you to migrate running AIX and Linux partitions and their hosted applications from one physical server to another without disrupting infrastructure services. The migration transfers the entire partition state, including processor context, memory, attached virtual devices, and connected users.
Partition Mobility helps you meet increasingly stringent service-level agreements (SLAs) because it allows you to proactively move running partitions and applications from systems requiring intervention or under heavy load to other systems.
Workload Partition Mobility is incorporated into the vLPAR automated deployment appliance.
