What is the reserve commit and on-demand usage?
什麼是備轉容量承諾？什麼是隨取隨用容量？
Reserve commit refers to the amount of storage capacity that a customer subscribes to as part of the Evergreen//Flex subscription. The reserve commit must meet the minimum level specified for the chosen hardware configuration and can be increased anytime during the Evergreen//Flex contract term. The reserve commit is billed in advance at the corresponding reserve rate.
On-demand usage is the capacity consumed above the reserve commitment and is billed in arrears at the corresponding on-demand rate.
備轉容量承諾指的是 Evergreen//Flex 訂閱方案客戶所訂閱的儲存容量。Evergreen//Flex 合約期間，備轉容量承諾必須滿足客戶所選的硬體建置專用最低要求，且可隨時增加用量。備轉容量承諾依其相應的容量費率計價。
隨取隨用的容量則為超出備轉容量承諾的使用量，並依相應的隨取用量費率計價，用後收費。
