Chapter 4. Multi-temperature storage
In this chapter, we describe multi-temperature storage to optimize the use of the
various types of storage available for an application environment.
Multi-temperature storage reserves faster, more expensive storage for critical
data, and slower, less expensive storage for all other data. Using this
multi-temperature storage approach helps to balance storage purchases across
solid-state drive (SSD), serial-attached SCSI (SAS), and Serial Advanced
Technology Attachment (SATA) storage, and to optimize storage budgets.
