Main Page Server Software Linux Linux-Storage LVM. ï»¿ Partition alignment is understood to mean the proper alignment of partitions to the reasonable boundaries of a data storage device (such as a hard disk, solid-state drive (SSD) or RAID volume). Proper partition alignment ensures ideal performance during data access. Incorrect partition alignment will cause reduced performance, especially with regard to SSDs (with an internal page size of 4,096 or 8,192 bytes, for example), hard disks with four-kilobyte (4,096 byte) sectors and RAID volumes.
Equivalence Partitioning . Rex Black, President, RBCS, Inc. To celebrate completion of the update to Advanced Software Testing: Volume I, here is an excerpt of Chapter 3. This is the central chapter of the book, addressing test design techniques. We start with the most basic of specification-based test design techniques, equivalence partitioning. Conceptually, equivalence partitioning is about testing various groups that are expected to be handled the same way by the system and exhibit similar behavior. Those groups can be inputs, outputs, internal values, calculations, or time values,
