Abstract
Method and system are provided for storage capacity allocation. The method includes: providing a storage pool having multiple storage drive arrays; designating an initial available storage capacity in the storage pool; and allocating the remaining storage capacity in the storage pool to distributed spare space, wherein distributed spare space spreads portions of a spare drive across multiple storage drives in an array. The method also includes: monitoring an amount of available storage capacity as data is stored to the storage pool and determining when a threshold of a minimum available storage capacity is reached; and re-allocating one or more distributed spare drives from an array to available storage capacity when the threshold of the minimum available storage capacity is reached.
