Planning the storage

Last published : Jun 11, 2026
Veritas InfoScale provides the following options for shared storage:
  • CVM
CVM provides native naming (OSN) as well as enclosure-based naming (EBN).
Use enclosure-based naming for easy administration of storage. Enclosure-based naming guarantees that the same name is given to a shared LUN on all the nodes, irrespective of the operating system name for the LUN.
  • CFS
  • For SF Oracle RAC: Local storage
With FSS, local storage can be used as shared storage. The local storage can be in the form of Direct Attached Storage (DAS) or internal disk drives.
  • For SF Oracle RAC: Oracle ASM over CVM
The following recommendations ensure better performance and availability of storage.
  • Use multiple storage arrays, if possible, to ensure protection against array failures. The minimum recommended configuration is to have two HBAs for each host and two switches.
  • Design the storage layout keeping in mind performance and high availability requirements. Use technologies such as striping and mirroring.
  • Use appropriate stripe width and depth to optimize I/O performance.
  • Use SCSI-3 persistent reservations (PR) compliant storage.
  • Provide multiple access paths to disks with HBA/switch combinations to allow DMP to provide high availability against storage link failures and to provide load balancing.
