Use this checklist to review storage minimum requirements and assist with configuration planning.

Table 1-5 Storage Checklist for Oracle Database

Check	Task
Minimum local disk storage space for Oracle software	At least 6.5 GB for Oracle Database Enterprise Edition At least 6.0 GB for Oracle Database Standard Edition 2 At least 7.0 GB for an Oracle Restart installation Note: Oracle recommends that you allocate approximately 100 GB to allow additional space for applying any future patches on top of the existing Oracle home. For specific patch-related disk space requirements, please refer to your patch documentation.
Recommended file system	Ensure that you have one of the following storage options available: Oracle Automatic Storage Management (Oracle ASM) NTFS File System or Resilient File System (ReFS)
Select Database File Storage Option	Ensure that you have one of the following storage options available: File System Oracle recommends that the file system be separate from the file systems used by the operating system or the Oracle software. The file system can be any of the following: - A file system on a disk that is physically attached to the system - A file system on a logical volume manager (LVM) volume or a redundant array of independent disks (RAID) device Oracle Automatic Storage Management (Oracle ASM) Oracle ASM is installed as part of an Oracle Grid Infrastructure installation. If you plan to use Oracle ASM, then you must install Oracle Grid Infrastructure before you install and create the database. Starting with Oracle Database 21c, the name of Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is changed to Oracle Advanced Cluster File System (Oracle ACFS). Starting with Oracle Database 21c, the Oracle Grid Infrastructure feature Oracle Advanced Cluster File System (Oracle ACFS) is desupported with Microsoft Windows. Caution: Oracle ACFS and Oracle Automatic Storage Management Dynamic Volume Manager (Oracle ADVM) will not be accessible after you install or upgrade to Oracle Grid Infrastructure 21c.
