153Using capabilities, templates and rules
Storage layout rules
parity
The parity rule defines whether redundancy should be parity based (that is,
RAID-5) as implemented in either hardware or software. The value can be true
or false.
The following example demonstrates the application of the parity rule:
■ Define a template for providing reliability using software RAID-5:
volume_template Raid5Volume {
provides Raid5Capability, Raid5LogMirroring
rules {
parity true
stripe ncols - nmaxcols
log nlogs {
type raid5
}
}
};
striped
The striped rule indicates whether a volume or mirror is to be striped.
If
striped is set to true, the number of columns is not necessarily greater than
one as striping can be implemented in hardware as well as software.
The following example demonstrates the application of the striped rule:
■ Define a template for providing reliability using mirrors, but where striping
is not allowed:
volume_template ReliableConcat {
provides Reliable, Concat
rules {
mirror NMIRS
striped false
}
};
