This chapter discusses issues to consider about the storage subsystem before you configure Oracle Automatic Storage Management (Oracle ASM). When preparing your storage to use Oracle ASM, first determine the storage option for your system and then prepare the disk storage for your specific operating system environment.
When configuring your system's storage, you must consider the initial capacity of the system and your plans for future growth. Oracle ASM simplifies the task of accommodating growth. However, your growth plans can affect choices, such as the size of the Oracle ASM disks. You must also consider that I/O performance depends on the interconnect between the storage and host, not just the storage disks. As you scale up the number of nodes in a cluster, you must also scale up the storage subsystem.
