Default for "remain until" is 1 week, there is also pool retention policy which is set by default, this will cause snaps to delete when the value set in pool is reached. Confirm what is true about system defined Snapshots they are not editable Max VDisk size for professional VSA? 50 TB What is needed to build a storage pool in unityVSA? VDISK What is the max number of Vdisk for VSA? 16 Max number of unityVSA snapshots? 128 What is the min OE UnityVSA can be deployed on?

Thick provision eager zero Max number of synchronous destinations? 1 Max number of Asynchronous destinations? 4 Customer is using a 200GB flash drive for fast cache, they try to add a 400gb drive and get any error, why? You can only add the same size to the drive to fast cache. What type of drives does unity support for fast cache? 200gb and 400gb You have 1tb fs, using 250GB and pool usage is 450, How much space will the pool regain if you shrink the FS to 300gb? 150 The filesystem is 1 TB in size and contains 250 GB of data. This filesystem is not fully allocated and only 450 GB of Pool Storage is in use. The user wishes to Shrink the filesystem to 300 GB in size. The user makes the request to shrink the 1 TB filesystem by 700 GB to a new size of 300 GB. The Storage Manager scans the space involved and determines some data must be moved or Evacuated from the space to be reclaimed. The data is moved to free space within the filesystem to complete the Evacuation. The filesystem is resized to 300 GB, freeing up 150 GB of storage. Finally, the 150 GB of newly freed space is returned to the Storage Pool and is added to the Storage Pool free space. What can you change the fast vp settings? tireing policy under lun What can you change in the advance fast vp settings? Under pool you can, pause data relocation, change relocation rate, and modify relocation schedule. When do you configure Unity IP address?

Or from CLI you can run svc_initial_config command is used to configure an IPv4 and/or IPv6 address for the management interface of an unconfigured Unity system. UnityVSA is installed on ESXi hypervisor using? The Unity storage software stack, running on a purpose built hardware, is virtualized and encapsulated into an OVA file which can be deployed in an ESXi host. How to confirm, unity or VSAunity is good after install? Run svc_diag Snapshot hierarchy? Can be to nest copied and shared snapshots that form a hierarchy of snapshots to a maximum of 10 levels deep, They are always RW What is the min and max time out for block async? 5 minutes and 1440 minutes (24 hours). How do you choose a disk for copy to spare? You don't. it works just like VNX2 From destination of asynchronous FS, what are the options? The destination can only failover. You can also resume after failover. From source of async FS, what are the options? Pause Sync Failover sync, resume, failover,failback Soruce of sync replication options?
