Abstract: A method for access control, the method may include (a) receiving, by a file server, an access request for allowing a user to access a file system entity, the user is identified by a first file system protocol (FSP) user identifier, (b) converting the first FSP user identifier to a first access control user identifier (ACUI) of the user, the first ACUI represents a combination of the user and the first FSP, (c) searching, within an access control data structure (ACUI), for a relevant access control rule associated with a member of a multiprotocol set of ACUIs of the user, wherein the multiprotocol set includes the first ACUI of the user and at least one other ACUI of the user that represents at least one combination of the user and at least one other FSP, and (d) responding to the access request based on the relevant access control rule, when finding the relevant access control.

Abstract: A method for monitoring a storage system, the method may include (a) generating a compute entity (CE) storage metric by each CE of a group of CEs to provide multiple CE storage metrics, wherein the multiple CE metrics are related to a monitoring period; and (b) calculating, during a calculation period, a group metric based on the multiple CE storage metrices; wherein the calculating includes performing multiple calculations iterations, wherein each calculation iteration includes (a) selecting an updating CE that belongs to the group of CEs and was not previously selected during the calculation period, (b) accessing, by the updating CE, a shared data structure that stores the group storage metric, and (c) updating the group storage metric using the CE storage metric of the updating CE.
