In the post-process compression, the plaintext data is generated by decompressing the in-line compressed data read from the one or more storage drives. In the post-process compression, post-process compressed data is generated by executing a compression process including second dictionary compression on the plaintext data using the processor, the second dictionary compression being more excellent in character string search capability than the first dictionary compression, and the post-process compressed data is stored in the one or more storage drives.
According to a preferred aspect of the invention, provided is an information processing apparatus including a processor and a storage device. A penalty coefficient setting unit is implemented by the processor and the storage device using a solution finding function for obtaining a solution of a combinatorial optimization problem using a cost function and a constraint condition. The penalty coefficient setting unit sets a penalty function and a penalty coefficient based on the constraint condition related to a logical operation imposed between two variables of the cost function and a value of a model coefficient of the cost function such that the solution of the combinatorial optimization problem satisfies the constraint condition, and searches for the solution of the combinatorial optimization problem based on the penalty function and the penalty coefficient.
Provided is a storage system and a storage system management method that are capable of providing continuous I/O processing by switching a queue used for I/O control on a controller side. The storage system includes a first protocol chip, a second protocol chip, a first controller, and a second controller. The first protocol chip and the second protocol chip receive I/O commands from a host. The first controller includes a first CPU. The second controller includes a second CPU. In accordance with an instruction from the first controller, the first protocol chip halts the first CPU, and switches a Qset for sending the I/O commands received by the first protocol chip from Qset 11 to Qset 12.
An interface module includes: a non-volatile storage area that stores one or more versions of firmware and a mode file; and a processor that executes a program code included in the firmware, in which each version of the firmware includes: a plurality of protocol-based program codes; and an activation unit that activates at least one of the plurality of protocol-based program codes based on description of the mode file.
The present invention relates to a storage system capable of connecting a drive having multiple kinds of interfaces and comprising a storage controller having a processor and built-in memory. When the drive and storage controller are connected, a plurality of communication channels are formed between them. The plurality of communication channels include a first communication channel, via a first interface, incapable of accessing the built-in memory even when the communication connection is established, and a second communication channel, via a second interface, capable of accessing the built-in memory when the communication connection is established. At a specified timing when the communication connection via the second communication channel is not established, the processor executes authenticity verification processing of the drive based on information acquired from the drive by using the first communication channel; and permits establishment of the communication connection via the second communication channel when the authenticity is confirmed.
