Samsung patents method to save power in storage servers
Samsung has filed a patent for a method that manages how much power storage devices in a server use. The system receives a "power token" from an application that indicates how much power it needs, then groups storage devices into tiers based on those needs. This allows the server to put less critical storage into low-power modes to save energy.
In the filing’s own words
A method for managing power state of one or more storage devices associated with a storage server includes receiving a power token generated for each of one or more host applications from service entity associated with storage server. The power token indicates power expectation corresponding to each host application. The storage server dynamically configures one or more power tiers based on the power expectation indicated in power token for each host application. Each power tier comprises group of storage devices configured to operate at a power state corresponding to the power tier. The storage server allocates each host application to a one power tier among configured power tiers for execution at the desired power state, based on the received power token. Some example embodiments provide a dynamic power management strategy to reduce power consumption by storage devices.
What exactly they claim (claim 1)
1. A method of managing a power state of one or more storage devices associated with a storage server, the method comprising: receiving, by the storage server, a power token generated for each of one or more host applications from a service entity associated with the storage server, wherein the power token indicates a power expectation corresponding to each of the one or more host applications; configuring dynamically, by the storage server, one or more power tiers based on the power expectation indicated by the power token received for each of the one or more host applications, wherein each of the one or more power tiers comprises a group of storage devices configured to operate at a desired power state; and allocating, by the storage server, each of the one or more host applications to a suitable power tier among the one or more power tiers for execution at the desired power state, based on the power token received for each of the one or more host applications.
