Abstract
A method for striping based on evaluated rules, the method may include determining a compatibility, with a storage system utilization policy, of storing stripes under evaluated rules; wherein the evaluated rules define a stripe size, a number of parity chunks per stripe, and maximal numbers of chunks within a stripe per different failure domains of different size ranges; checking whether the storing of the stripes is compatible with the storage system utilization policy; when finding that the storing of the stripes is not compatible then searching for one or more changes of one or more of the maximal numbers that yields compliant one or more maximal numbers that once applied results in a compliance with the storage system utilization policy; applying the compliant one or more maximal numbers when finding the compliant one or more maximal numbers; and determining that the evaluated failure domain rules are non-compliant when failing to find the compliant one or more maximal numbers.
