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.

Supported Methods
Table 89 Methods for TPD_BlockStatisticsService
DescriptionMethod
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
GetStatisticsCollection ()
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
