IBM Turbonomic Glossary

IWO (Intersight Workload Optimizer) is a version of the Turbonomic platform that is specially designed to run within  Cisco Intersight. IWO integrates the Turbonomic ARM solution so that Intersight users can claim targets in their environment, take advantage of Turbonomic analysis, and execute actions to assure performance and efficiency.

IOPS is a common performance measurement for computer storage devices, such as hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN). It refers to the maximum number of reads and writes to non-contiguous storage locations. You can set IOPS capacity and utilization constraints in Turbonomic policies.

For cloud storage, Turbonomic considers IOPS utilization to drive storage scaling actions. For on-prem storage, IOPS capacity for a disk array takes precedence. Datastores that are members of a disk array always have the IOPS capacity that is set to the disk array.

For hyperconverged infrastructure, you can set an effective IOPS capacity for the datastores on the hyperconverged host. Turbonomic uses the value that you set to provide an estimate of effective IOPS capacity for each host in the cluster.

An ISO is an electronic file that contains the identical content of an optical disc, including the folder and file hierarchy. Using an .ISO file extension, ISO images are created to distribute the disc’s data over a network in order to burn a CD or DVD at the destination computer.

In Turbonomic, these images can be reported as wasted storage, which can throw off reports. You can avoid this by updating the Default Storage Policy Storage Settings to ignore these files.

The method for updating Turbonomic offline is via an ISO.

ITIL is a best-practice framework for facilitating the delivery and management of IT services. Turbonomic integrates with software based on ITIL frameworks, such as ServiceNow. 

The ITIL framework is delivered in five publications covering various parts and stages of the IT service lifecycle. It was initially developed by the UK Central Computer and Telecommunications Agency (CCTA) in the 1980s. Since 2013, it has been owned by the UK Cabinet Office and Capita in a joint venture called Axelos, which controls licensing.

Kafka is a component of the Turbonomic platform that runs the Kafka stream-processing service. The Kafka service is an open-source, stream-processing software platform developed by Apache to handle real-time data feeds, integration, and analytics. Kafka is the bus over which Turbonomic communicates Data Transfer Object (DTO) data between its platform components.

Latency is the time it takes for a storage device to reply to a request for data. Charts show the latency experienced by all VMs and hosts that access a given datastore. 

In Turbonomic, latency is expressed as a commodity that can be bought and sold. For a given datastore, there is no real capacity for Latency, but Turbonomic assigns a default storage latency capacity of 100ms.

A license is a file that you install on a Turbonomic instance to gain access to Turbonomic features. 

Under the Settings View, the license summary displays license details such as total workloads licensed, workloads in use, and the currently activated features.

If you exceed your workload count, Turbonomic will continue to manage your environment, but you will not be able to add new targets or upgrade your instance. If your license expires, Turbonomic will continue to monitor your environment, but you cannot execute recommended actions.

Manual is an Action Mode that directs Turbonomic to post the actions that it generates and gives you the option of executing them via the Turbonomic user interface.

Turbonomic posts the generated actions in the Pending Actions chart.

MariaDB is an open-source relational database provided by MariaDB.org that Turbonomic uses for persistent storage of historic data. By default, Turbonomic includes MariaDB in the Open Virtualization Appliance (OVA) installation package.
