Cycling out dispersed storage processing units from access pools to perform expensive operations
First Claim
1. A method comprises:
- identifying, by a dispersed storage (DS) processing unit of a plurality of DS processing units of a dispersed storage network (DSN), a DSN operation to be performed that will adversely interfere with processing of DSN access requests;
sending, by the DS processing unit, a suspension request to a process balancing module of the DSN, wherein the suspension request is for temporarily suspending processing of DSN access requests;
determining, by the process balancing module, whether sufficient processing resources of active DS processing units of the plurality of DS processing units are available for processing DSN access requests on behalf of the DS processing unit; and
when determined that sufficient processing resources are available;
granting, by the process balancing module, the suspension request; and
allocating, by the process balancing module, DSN access requests of the DS processing unit to one or more of the active DS processing units.

Abstract
A method includes identifying, by a dispersed storage (DS) processing unit of a plurality of DS processing units of a dispersed storage network (DSN), a DSN operation to be performed that will adversely interfere with processing of DSN access requests. The method further includes sending, by the DS processing unit, a suspension request to a process balancing module of the DSN where the suspension request is for temporarily suspending processing of DSN access requests. The method further includes determining, by the process balancing module, whether sufficient processing resources of active DS processing units of the plurality of DS processing units are available for processing DSN access requests on behalf of the DS processing unit. When determined that sufficient processing resources are available, the method further includes granting the suspension request, and allocating DSN access requests of the DS processing unit to one ore of the active DS processing units.

10. A computer readable memory comprises:
-
a first memory that stores operational instructions that, when executed by a dispersed storage (DS) processing unit of a plurality of DS processing units of a dispersed storage network (DSN), causes the DS processing unit to; identify a DSN operation to be performed that will adversely interfere with processing of DSN access requests; send a suspension request to a process balancing module of the DSN, wherein the suspension request is for temporarily suspending processing of DSN access requests; and a second memory that stores operational instructions that, when executed by the process balancing module, causes the process balancing module to; determine whether sufficient processing resources of active DS processing units of the plurality of DS processing units are available for processing DSN access requests on behalf of the DS processing unit; and when determined that sufficient processing resources are available; grant the suspension request; and allocate DSN access requests of the DS processing unit to one of more of the active DS processing units. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
