Abstract
Aspects of the disclosure are directed to reducing or eliminating emergency capacity usage in a storage system by including an in-process space reclamation and/or one or more mitigation mechanisms. The in-process space reclamation can be implemented in addition to a background space reclamation. The one or more mitigation mechanisms can be associated with a basis for write requests. The in-process space reclamation and/or mitigation mechanisms allow for lowering emergency capacity reservation, thus saving storage costs.
Claims12
A method for reducing emergency storage capacity of a storage system, the method comprising:
- monitoring, by one or more processors, an amount of time since a background space reclamation has been performed;
- determining, by the one or more processors, that the amount of time since the background space reclamation has been performed meets or exceeds an idling threshold;
- based on determining that the amount of time meets or exceeds the idling threshold, triggering, by the one or more processors, an in-process space reclamation separate from the background space reclamation, the in-process space reclamation being bound to one or more write processes for the storage system by running on the same hardware and being programmed in a same memory address space as the one or more write processes;
- monitoring, by the one or more processors, a storage usage for the storage system;
- determining, by the one or more processors, that the storage usage meets or exceeds a storage usage threshold;
- and
- based on determining that the storage usage meets or exceeds the storage usage threshold, triggering, by the one or more processors, the in-process space reclamation and adjusting, by the one or more processors, a basis for the write processes, wherein the adjusting further comprises at least one of:
- transcoding data to a wider encoding scheme;
- or
- performing data compression on incoming traffic, including initiating compression of incoming traffic or increasing a compression ratio for the incoming traffic.
7 more elements
A system comprising:
- one or more processors;
- and
- one or more storage devices coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations for reducing emergency storage capacity of a storage system, the operations comprising:
- monitoring an amount of time since a background space reclamation has been performed;
- determining that the amount of time since the background space reclamation has been performed meets or exceeds an idling threshold;
- based on determining that the amount of time meets of exceeds the idling threshold, triggering an in-process space reclamation separate from the background space reclamation, the in-process space reclamation being bound to one or more write processes for the storage system by running on the same hardware and being programmed in a same memory address space as the one or more write processes;
- monitoring a storage usage for the storage system;
- determining that the storage usage meets or exceeds a storage usage threshold;
- and
- based on determining that the storage usage meets or exceeds the storage usage threshold, triggering the in-process space reclamation and adjusting a basis for the write processes, wherein the adjusting further comprises at least one of:
- transcoding data to a wider encoding scheme;
- or
- performing data compression on incoming traffic, including initiating compression of incoming traffic or increasing a compression ratio for the incoming traffic.

- determining that the amount of time since the background space reclamation has been performed meets or exceeds an idling threshold;
- based on determining that the amount of time meets or exceeds the idling threshold, triggering an in-process space reclamation separate from the background space reclamation, the in-process space reclamation being bound to one or more write processes for the storage system by running on the same hardware and being programmed in a same memory address space as the one or more write processes;
- monitoring a storage usage for the storage system;
- determining that the storage usage meets or exceeds a storage usage threshold;
- and
- based on determining that the storage usage meets or exceeds the storage usage threshold, triggering the in-process space reclamation and adjusting a basis for the write processes, wherein the adjusting further comprises at least one of:
- transcoding data to a wider encoding scheme;
- or
- performing data compression on incoming traffic, including initiating compression of incoming traffic or increasing a compression ratio for the incoming traffic.
