Abstract
Techniques for adding a directory entry to an existing directory data structure maintained by a storage system for storing a plurality of directory entries are provided. A first storage index block is used for storing a pointer to a first hash value from among a plurality of hash values. A second storage index block is allocated when the first storage index block has reached a threshold level for storing pointers to hash values for the plurality of directory entries. A group of pointers including a pointer to a second hash value from among the plurality of hash values is selected. The group of pointers is stored in the second storage index block with a pointer to a third hash value from among the plurality of hash values such that the directory entry can be searched using the plurality of hash values.
