A method, performed by a reallocation component, for managing a reallocation of information from a source memory sled to a target memory sled, wherein the information is used by an application executing in a compute sled, wherein the information comprises a respective content allocated on a respective source page of the source memory sled, wherein the source memory sled comprises a source table indicating a respective source status for each said respective source page, wherein the respective source status indicates that said respective source page is at least one of being used by the application and/or not related to the application, wherein the target memory sled comprises a target table indicating a respective target status for each respective target page of target pages of the target memory sled, wherein the information is to be reallocated to said target pages of the target memory sled, wherein the method comprises: obtaining an indication to initiate reallocation of the information relating to the application; for said each respective source page whose status indicates that said respective source page is used by the application, initiating reallocation of the respective content allocated on said each respective source page of the source memory sled to a respective target page of the target memory sled, wherein initiating comprises: selecting a first set of source pages based on a set of utility indications comprising access frequency, time stamp of latest access to said each source page, latency and memory type; beginning with initiation of reallocation of the first set of source pages, and then continuing, after the first set of source pages has been reallocated, with initiation of reallocation of a second set of source pages selected based on the set of utility indications, wherein the first set of source pages is more frequently accessed than the second set of source pages; and for said each respective source page whose status indicates that said respective source page is not related to the application, setting the respective target status for the respective target page to indicate uninitialized, while refraining from reallocating the respective content allocated on said each respective source page whose status indicates that said respective source page is not related to the application. obtaining an indication to initiate reallocation of the information relating to the application; for said each respective source page whose status indicates that said respective source page is used by the application, initiating reallocation of the respective content allocated on said each respective source page of the source memory sled to a respective target page of the target memory sled, wherein initiating comprises: selecting a first set of source pages based on a set of utility indications comprising access frequency, time stamp of latest access to said each source page, latency and memory type; beginning with initiation of reallocation of the first set of source pages, and then continuing, after the first set of source pages has been reallocated, with initiation of reallocation of a second set of source pages selected based on the set of utility indications, wherein the first set of source pages is more frequently accessed than the second set of source pages; and for said each respective source page whose status indicates that said respective source page is not related to the application, setting the respective target status for the respective target page to indicate uninitialized, while refraining from reallocating the respective content allocated on said each respective source page whose status indicates that said respective source page is not related to the application. selecting a first set of source pages based on a set of utility indications comprising access frequency, time stamp of latest access to said each source page, latency and memory type; beginning with initiation of reallocation of the first set of source pages, and then continuing, after the first set of source pages has been reallocated, with initiation of reallocation of a second set of source pages selected based on the set of utility indications, wherein the first set of source pages is more frequently accessed than the second set of source pages; and for said each respective source page whose status indicates that said respective source page is not related to the application, setting the respective target status for the respective target page to indicate uninitialized, while refraining from reallocating the respective content allocated on said each respective source page whose status indicates that said respective source page is not related to the application.
