  • Publication number: 20180217935
    Abstract: A method for reading data stored in a redundant array of independent disks (RAID). The RAID includes a RAID controller, a first cache, and a hard disk including a hard disk controller and a second cache. The method includes: receiving a read request, wherein the read request comprises an identifier of a to-be-read logical block; sending a first command to a hard disk controller of the hard disk when the first cache does not comprise data stored in the to-be-read logical block, wherein the first command is used to instruct the hard disk controller of the hard disk to return the data of the to-be-read logical block from the second cache of the hard disk; outputting the returned data, and caching the returned data in the first cache; and controlling the hard disk controller of the first hard disk to delete the returned data stored in the second cache.

  • Publication number: 20170364300
    Abstract: In a method for controlling data stored in a Solid State Disk (SSD) of a data storage system, a storage controller obtains stability information of a data segment. The stability information includes a reference count of the data segment and a length of a period of time the data segment is stored in the SSD. The storage controller identifies a stability level of the data segment according to the stability information, and sends the stability level of the data segment to the SSD. The SSD moves the data segment to a storage block that corresponds to the stability level. Thereby, the SSD can store data segments having a same stability level together.

  • Patent number: 9772790
    Abstract: In a method for controlling data stored in an Solid State Disk (SSD) of a data de-duplication system, a storage controller obtains stability information of a data block. The stability information comprises a reference count of the data block and a length of a period of time when the data block is stored in the SSD. The storage controller identifies a stability level of the data block according to the stability information, and sends the stability level of the data block to the SSD. The SSD moves the data block to a target block which corresponds to the stability level. Thereby, the SSD can store data blocks having a same stability level together.

  • Patent number: 9733844
    Abstract: A method for extending life of a storage system, wherein a storage controller determines a source solid-state disk (SSD) in a disk group with a capacity usage ratio greater than an average capacity usage ratio of the disk group. The capacity usage ratio of the source SSD is a ratio of a used capacity of the source SSD to an available capacity of the source SSD. The storage controller selects at least one destination SSD in the disk group with a capacity usage ratio less than the average capacity usage ratio of the disk group. And then the storage controller calculates an amount of data to be migrated from the source SSD, based on the capacity usage ratio of the source SSD and the average capacity usage ratio. At last, the storage controller migrates the data to be migrated from the source SSD to the one or more destination SSDs.

  • Publication number: 20170093917
    Abstract: Systems and methods for manipulating online behavioral tracking policies are provided. According to one embodiment, a hypertext transfer protocol (HTTP) response transmitted from a web server to a client is captured by a network security device. A status of the client is determined by the network security device. An online behavioral tracking policy associated with the client is identified by the network security device based on the determined status. The identified online behavioral tracking policy is enforced by the network security device by modifying the HTTP response. The modified HTTP response is transmitted by the network security device to the client.
