| description | To provide a storage system configured to accurately evaluate a failure risk of a storage drive having a flash memory as a storage medium, and a control method thereof.MEANS FOR SOLVING THE PROBLEM: In a storage system, a RAID group includes a plurality of storage drives each having a flash memory as a storage medium. The storage system is configured to: apply operation log of the storage drive to a first model; apply operation log of a peripheral device to a second model; obtain a first prediction value for predicting a failure of the storage drive on the basis of the first model; and obtain a second prediction value for predicting a failure of the peripheral device on the basis of the second model.SELECTED DRAWING: Figure 1
【課題】記憶媒体としてのフラッシュメモリを有する記憶ドライブの故障リスクを正確に評価できる、ストレージシステム、及び、その制御方法を提供する。【課題解決手段】本発明は、ストレージシステムであって、RAIDグループは、記憶媒体としてのフラッシュメモリを有する記憶ドライブを複数有し、記憶ドライブの稼働ログを第１のモデルに適用することと、周辺装置の稼働ログを第２のモデルに適用することと、第１のモデルに基づいて、記憶ドライブの故障を予測するための第１の予測値を得ることと、第２のモデルに基づいて、周辺装置の故障を予測するための第２の予測値を得ることと、を特徴とする。【選択図】図１ |
