Dell Unity NAS file systems are well suited for Oracle. They provide scalability, large system size, flexible file system, storage efficiency, security, isolation, availability, recoverability, virtualization, and performance.
Dell Unity file systems provide scalability in several areas, including maximum file system size, which makes Dell Unity storage ideal for Oracle environments. Dell Unity OE version 4.2 increases the maximum file system size from 64 TB to 256 TB for all file systems. File systems can also be shrunk or extended to any size within the supported limits. Dell Technologies recommends configuring storage objects that are 100 GB at a minimum and preferably 1 TB in size or greater.
Dell Unity storage supports thin-provisioned file systems. Starting with Dell Unity OE version 4.2, Unisphere can also create thick file systems. When using Dell Unity file storage with Oracle, consider using thin-provisioned file systems. Dell Unity also provides increased storage flexibility with manual or automatic file system extension and shrinking with reclaim.
Dell Unity includes full-quota support to allow administrators to limit the amount of space that can be consumed from a user of an NFS file system or directory. When working with Oracle, quotas are not usually necessary. If deciding to use quotas, carefully consider their impact on managing the Oracle environment.
Unity NFS file systems can host Oracle datafiles that exist on ASM (Figure 22), file system (Figure 23), or both.
