Abstract: In some examples, a controller for a storage system separate from a host system checks whether a storage cartridge in a storage system is associated with an indication set, in an electronic memory, during a configuration operation in the storage system to indicate write protection is enabled for the storage cartridge. In response to determining that the storage cartridge is associated with the indication, the controller triggers the write protection for the storage cartridge to prevent writing of data to the storage cartridge if the storage cartridge already contains previously written data.

Abstract: Example implementations relate to virtual persistent volumes. In an example, a storage virtualization system receives performance metrics related to usage of a virtual persistent volume by a containerized application. The performance metrics are identified in an application data store profile, and the application data store profile is identified based on an application manifest of the containerized application. The virtual persistent volume is modified based on an analysis of the performance metrics.

Abstract: Systems and methods are described for providing per traffic class routing of data within a network. A network switch has the capability to classify traffic data based on High Performance Computing (HPC) related characteristics. Traffic classes are defined based on aspects of HPC, such as routing, ordering, redirection, quiesce, HPC protocol configuration, and telemetry. A switch can receive packets at an ingress port of a switch fabric, and determine traffic classifications for the packets. The traffic classification is selected from a group of defined traffic classes. Then, the switch can generate a fabric specific flag for the at least one packet that indicates the determined traffic classification, where the fabric specific flag is used for routing packets based on their assigned traffic classification. Examples of traffic classes include: low latency class; dedicated access class; bulk data class; best efforts class; and scavenger class.
