红帽全球峰会2.2. Storage
为 SAP HANA Scale-Out 场景配置存储有两种方法：
- 共享存储
- 非共享存储
存储级别的两个横向扩展环境之间没有通信。因此，必须在每个横向扩展环境中完成存储配置，以确保 SAP HANA System Replication 按预期工作。
2.2.2. 非共享存储
非共享存储配置需要集成存储连接器。存储连接器通过 SCSI 或 LVM 锁定机制管理对 LUN 或 LVM 设备的访问。对于此配置类型，需要 WWID 或者 LVM 设备。对于非共享存储配置，每个扩展环境都需要一个共享目录。此配置在 SAP HANA 光纤通道存储连接器管理指南 中进行了描述。

如果共享存储由文件系统资源管理，则不应将挂载添加到 /etc/fstab 中。
