摘要:
By writing a command for transferring data from a first cluster to a second cluster and the second cluster writing data that was requested from the first cluster based on the command into the first cluster, data can be transferred in real time from the second cluster to the first cluster without having to issue a read request from the first cluster to the second cluster.

At the time of a fan failure of a plurality of fans for cooling redundant controllers, data loss can be avoided even if a power source of each controller is controlled.A storage system includes: a first controller for controlling a first power source; a plurality of first fans for cooling the first controller; a second controller for controlling a second power source; a plurality of second fans for cooling the second controller; and a storage device including a plurality of storage units; wherein if a fan failure of the first fans occurs, the first controller controls the first power source in a standby state on condition that the second controller is in a normal state; and if the second power source is in the standby state, the first controller executes destaging processing and then controls the first power source in the standby state.

Disclosed is a storage device 10 in which CPUs 132 are redundantly configured, and which is thus capable of performing dual-writing of data into cache memories 134 respectively coupled to the CPUs 132. In the storage device 10, general-purpose processors each including an NTB_Port 72, PCI_Ports 73 and a Memory_I/F 74 are used as CPUs 132 of the CPUs 132. In the storage device 10, when a first PCIe_Port 73 determines not to perform the dual-writing, a first NTB_Port 1322 writes data into only one of the cache memories 134, and when the first PCIe_Port 73 determines to perform the dual-writing, the first NTB_Port 1322 writes data into one of the cache memories 134 while writing the data into the other one of the cache memories 134 via the other one of the CPUs 132.
摘要:
The method for producing a carbonyl compound according to the invention comprises a step of obtaining a carbonyl compound by oxidation of a secondary alcohol in the presence of a catalyst, wherein the catalyst comprises a carrier obtained by the use of a styrene-based polymer with side chains containing crosslinkable functional groups, wherein the crosslinkable functional groups in the carrier are crosslinked, gold-platinum nanosize clusters supported on the carrier and carbon black supported on the carrier. The production method allows production of a carbonyl compound by oxidation of a secondary alcohol, with high selectivity and a high conversion rate.

Provided is an information processing apparatus including a local memory for storing a control program, a flash memory for storing a boot program, a processor for controlling the overall controller, a chipset for relaying the transfer of data among the respective components, and a logical control circuit arranged between the chipset and the flash memory. The logical control circuit performs information conversion processing to accommodate the logical configuration of the chipset and the flash memory when sending and receiving information between the chipset and the flash memory. This information conversion processing includes the steps of translating a serial address signal output from the chipset into a parallel address signal, translating a serial data signal output from the chipset into a parallel data signal, and translating a parallel data signal output from the flash memory into a serial data signal.
