Dell UnityVSA™ is a software-defined storage solution which provides most of the same features as Dell Unity, but can be deployed on a customer’s VMware infrastructure. Because Dell UnityVSA does not have dedicated hardware, and is installed on user-provided equipment, there are recommendations that are specific to this system.
It is recommended to use Dell UnityVSA HA for better system availability. UnityVSA provides redundancy by clustering 2 virtual SPs.
When provisioning storage to Dell UnityVSA, Dell Technologies recommends using “Thick Provision Eager Zeroed” to guarantee the capacity and provide the best performance.
When provisioning storage for Dell UnityVSA, it is recommended to use storage for the Dell UnityVSA Operating Environment that is physically separate from the storage that will be used for storage pools.
