Abstract
In one aspect, a method includes providing a server that stores a hash digest metadata table and configuring entries in the hash digest metadata table to include entries that include persistent fields and non-persistent fields. The hash digest metadata table maps a hash digest representing X-Page data to its metadata information. The persistent fields include a short hash digest field, a physical layout offset field, a deduplication reference count field and a flags field.
