(EN) Method, system and device for balancing and optimizing main placement group, and medium
(ZH) 一种主放置组均衡优化的方法、系统、设备及介质
Abrégé
(EN) The invention discloses a main placement group equalization optimization method, system and device, and a storage medium. The method comprises the following steps: obtaining a theoretical average value according to the total capacity of a cache disk and the total number of object storage devices; obtaining a weight corresponding to the object storage device based on the actual capacity occupied bythe object storage device and the theoretical average value; obtaining the total number of the current main placement groups, and obtaining the number of expected balanced main placement groups basedon the total number of the current main placement groups and the weight corresponding to the object storage device; reading the address of each placement group in the redundant group, obtaining a corresponding base value based on the address of each placement group and the address of the object storage device, and taking the placement group as a main placement group in response to the fact that the base value is less than a preset value; and repeating the previous step until the number of the main placement groups reaches the expected balanced number of the main placement groups. According tothe scheme provided by the invention, the number of the expected balanced main placement groups is calculated by calculating the weight of the object storage device, so the system performance is optimized.
(ZH) 本发明公开了一种主放置组均衡优化的方法、系统、设备和存储介质,方法包括以下步骤:根据缓存盘的总容量和对象存储设备的总个数得到理论平均值;基于对象存储设备占用的实际容量与理论平均值得到对象存储设备对应的权重;获取当前主放置组的总个数,并基于当前主放置组的总个数和对象存储设备对应的权重得到预期均衡主放置组的数量;读取冗余组里的每个放置组的地址,基于每个放置组的地址和对象存储设备的地址得到对应的基值,响应于基值小于预定值,将放置组作为主放置组;重复上一步骤直到主放置组的数量达到预期均衡主放置组的数量。本发明提出的方案通过计算对象存储设备的权重来计算预期均衡主放置组的个数,从而优化系统性能。
