The Space Types by Cylinder Percentage table in the Cylinder Allocation by Temperature and Grade view provides metrics about space types, storage grades, and data temperatures managed by Teradata Virtual Storage.

SPACE
Lists the conventional space types (Perm, WAL, Spool, RSpool, Depot, Journal, Durable, Other) as well as the unused cylinder space (Free).
GRADE
Lists the storage grade (Slow, Medium, Fast).
CYL
Lists the count of cylinders for a given space type, storage grade, or type-grade combination, in millions of cylinders or thousands (K) of cylinders.
TEMP
Lists the temperature (Cold, Warm, Hot).
% SPACE
Lists the percentage of cylinders for a storage grade in a given space type. When you filter the matrix by space type, the sum of this column for the space type is 100%. For example, if the number of cylinders (CYL) for WAL is 200 for slow grade, 400 for medium grade, and 200 for fast grade, the % SPACE column lists 25 for slow, 50 for medium, and 25 for fast, for a total of 100%. When you filter the table by All Zones, the sum of this column for all storage grades for a given space type is 100%. This column is displayed only if you filter the matrix by space type, or if you filter the table by All Zones.
% COLD
Lists the percentage of cylinders for a given space type-grade combination allocated to cold data. The sum of % COLD, % WARM, and % HOT is 100% for a given space type-grade combination. This column is displayed only if you filter the table by storage grade or by All Zones.
% WARM
Lists the percentage of cylinders for a given space type-grade combination allocated to warm data. The sum of % COLD, % WARM, and % HOT is 100% for a given space type-grade combination. This column is displayed only if you filter the table by storage grade or by All Zones.
% HOT
Lists the percentage of cylinders for a given space type-grade combination allocated to hot data. The sum of % COLD, % WARM, and % HOT is 100% for a given space type-grade combination. This column is displayed only if you filter the table by storage grade or by All Zones.
% SLOW
Lists the percentage of cylinders for a given space type-temperature combination allocated to slow grade storage. The sum of % SLOW, % MEDIUM, and % FAST is 100% for a given space type-temperature combination. This column is displayed only if you filter the table by data temperature or by All Zones.
% MEDIUM
Lists the percentage of cylinders for a given space type-temperature combination allocated to medium grade storage. The sum of % SLOW, % MEDIUM, and % FAST is 100% for a given space type-temperature combination. This column is displayed only if you filter the table by data temperature or by All Zones.
% FAST
Lists the percentage of cylinders for a given space type-temperature combination allocated to fast grade storage. The sum of % SLOW, % MEDIUM, and % FAST is 100% for a given space type-temperature combination. This column is displayed only if you filter the table by data temperature or by All Zones.
% OF ZONE
Lists the percentage of cylinders for a given space type in the temperature-grade combination. The sum of cylinder percentages in the temperature-grade-combination zone is 100%. This column is displayed only if you filter the table by a temperature-grade combination.
