About Smart Manager for Mainframe
Smart Manager for Mainframe is software that works together with Smart Tiers Z to help users manage
the data on volumes tiered to multiple kinds of storage media, such as SSD, SAS, and SATA.
Data saved on tiered volumes can be relocated to the appropriate tier based on the access frequency
by a process called tier relocation. The following figure shows an overview of tier relocation. Data
that is accessed frequently is moved to an upper tier, which consists of higher-speed storage media,
and data that is not so frequently accessed is moved to a lower tier, which consists of lower-speed
storage media.
Figure 1 Automatic data relocation across tiers according to the access frequency
After considering the performance requirements for certain data, if you want to locate the data in a
tier appropriate for the requirements, you can directly specify the tier in which the data is to be located.
For example, you can locate data that is not accessed frequently but requires quick response in an
upper tier.
