The cumulative count of I/Os. The cumulative count of all reads. The cumulative count of all writes. The cumulative count of data transferred in Kbytes (1024bytes = 1KByte). The cumulative count of data written in Kbytes (1024bytes = 1KByte). The cumulative count of data read in Kbytes (1024bytes = 1KByte). The cumulative elapsed I/O time (number of Clock Tick Intervals) for all I/Os as defined in 'Total I/Os'. This value can be divided by number of IOs to obtain an average response time. ClockTickInterval value can be obtained from TPD_BlockStatisticsCapabilities. It is set to 1 microsecond. The cumulative elapsed time for all Read I/Os for all cumulative Reads. The cumulative elapsed time for all Write I/Os for all cumulative Writes. Supported Methods Table 89 Methods for TPD_BlockStatisticsService Method GetStatisticsCollection () Description Retrieves statistics in CSV bulk format. The collection of statistics returned is determined by the list of element types passed in to the method and the manifests for those types contained in the supplied BlockStatisticsManifestCollection. If both the Elements and BlockStatisticsManifestCollection parameters are supplied, then the types of elements returned is an intersection of the element types listed in the Elements parameter and the types for which BlockStatisticsManifest instances exist in the supplied BlockStatisticsManifestCollection. The statistics are returned through a well-defined array of strings, whose format is specified by the StatisticsFormat parameter, that can be parsed to retrieve the desired statistics as well as limited information about the elements that those metrics describe. Please note that only CSV StatisticsFormat is supported. Replication Services Profile This new profile extends the functionality of the Copy Services Subprofile by including enhanced local replication for thinly provisioned storage objects, remote replication (not supported in this release), and support for replication groups and consistency group. Key features include: • Specify individual or Groups of elements to manage replication • Support Consistency Management • Handle local, and in the future remote, replication seamlessly • Explicitly replicate Thinly Provisioned elements • Offer different Copy Methodologies SMI-S Terminology: 1. Synchronized Replication - indicates that updates to a source element are reflected to the target element, although the target element may or may not be updated immediately 102 CIM API SMI-S Support
