Oracle^® Storage 12 Gb/s SAS PCIe RAID HBA, Internal Installation Guide For HBA Models 7110116 and 7110117

Valid Drive Mix Configurations With HDDs and SSDs

This HBA supports connectivity using labeled SATA II drives, SAS drives, or both. The following are some basic rules about the types of drives you can use:

• Within a logical volume:

  • You can mix SAS and SATA drives [either all solid state drives (SSDs) or all hard disk drives (HDDs)].

    ---

    Note - Though it is possible to mix SAS and SATA drives in a single RAID volume, Oracle does not support this configuration as it might cause performance issues with the drives.

    ---

  • You cannot mix HDDs and SSDs of any type.

• Within an enclosure (SAS expander or direct-connect SAS cable), you can mix any drive types, subject to any restrictions imposed by the enclosure.
