Abstract
In an information processing system, a storage control server (storage control node) that has received a read request of data from a compute server (compute node) transmits the read request to a drive box. The drive box that has received the read request from the storage control server reads encrypted read target data corresponding to the read request from non-volatile storage media, decrypts the read target data with key data acquired at a predetermined timing, and then transmits the decrypted read target data to the compute server as a read request source.
Claims15
An information processing system in which a drive box including one or more non-volatile storage media that store data and a storage control server that processes data input and output to and from the drive box are connected to each other via a network, wherein
- the storage control server manages key data for encrypting and decrypting the data,
- the drive box stores encrypted data and acquires the key data of the data at a predetermined timing,
- the storage control server that has received a read request of data from a compute server transmits the read request to the drive box,
- the drive box that has received the read request from the storage control server reads encrypted read target data corresponding to the read request from the non-volatile storage media, decrypts the read target data with the key data acquired at the predetermined timing, and then transmits the decrypted read target data to the compute server as a read request source.
A data transfer method by an information processing system in which a drive box including one or more non-volatile storage media that store data and a storage control server that controls a storage space provided by the drive box are connected to each other via a network, the method comprising:
- by the storage control server, managing key data for encrypting and decrypting the data;
- by the drive box, storing encrypted data and acquiring the key data of the data at a predetermined timing;
- by the storage control server that has received a read request of data from a compute server, transmitting the read request to the drive box;
- and
- by the drive box that has received the read request from the storage control server, reading encrypted read target data corresponding to the read request from the non-volatile storage media, decrypting the read target data with the key data acquired at the predetermined timing, and then transmitting the decrypted read target data to the compute server as a read request source.
