To use NFS storage in the VMware Validated Design, your environment must meet certain requirements for networking and bus technology.

  • All connections are made using 10 Gb Ethernet.

  • Jumbo frames are enabled.

  • 10K SAS (or faster) drives are used in the storage array.

You can combine different disk speeds and disk types in an array to create different performance and capacity tiers. The management cluster uses 10K SAS drives in the RAID configuration recommended by the array vendor to achieve the required capacity and performance.

Design Justification

Design Implication


Use 10K SAS drives for NFS volumes.

10K SAS drives provide a balance between performance and capacity. You can use faster drives.

  • vStorage API for Data Protection-based backups require high-performance datastores to meet backup SLAs.

  • vRealize Automation uses NFS datastores for its content catalog which requires high-performance datastores.

  • vRealize Log Insight uses NFS datastores for its archive storage which, depending on compliance regulations, can use a large amount of disk space.

10K SAS drives are more expensive than other alternatives.
