Abstract: Described herein is a rejuvenated asphalt and a method of rejuvenating asphalt comprising mixing a rejuvenator, bitumen, and aggregate to obtain an asphalt mixture, wherein the rejuvenator is present in an amount ranging from about 0.1-40 wt % by weight of the bitumen, and wherein at least 35 wt % of the bitumen is derived from recycled asphalt content. The rejuvenated asphalt provides desirable performance.

Abstract: Temporarily limiting access to a storage device, including: determining that a storage device of a plurality of storage devices in a storage system is operating outside of a defined performance range; determining that the storage device operating outside of the defined performance range may be caused by a rehabilitative action performed on the storage device; and modifying a storage operation issuance policy for one or more storage devices of the plurality of storage devices until a determination that the storage device is operating within the defined performance range.

Abstract: In one implementation, a system resource is added to a storage system, for a resource-preserving upgrade. An upgrade component is coupled to the storage system as a temporary storage system shelf. Storage drives are moved from the storage system to the upgrade component. One or more storage controllers of the upgrade component are promoted to take over data services from the storage system.

Abstract: A method for reservations in a storage system, is provided. The method includes determining status of all storage devices expected to be in the storage system, receiving a request for a reservation of a storage device, and determining a type of service to be performed on the storage device. The method includes determining whether the type of service is in a first class of services or a second class of services and granting or denying the reservation based on the type of service, wherein a reservation to perform a service in the first class of services is granted as a result of determining all the storage devices expected are online and wherein a reservation to perform a service in the second class of services is granted as a result of determining a sufficient subset of all the storage devices expected are online to perform reading and writing with redundancy.
