Dynamic Pools - Architecture
• In a Dynamic Pool, drives are partitioned into drive extents which are grouped into RAID extents across multiple drives
– Ensures redundancy by making sure a RAID extent does not contain two drive extents from a particular drive – Spare space automatically configured to meet sparing requirements
› No need for hot spares of unused drives
• RAID groups within Dynamic Pools are collections of RAID extents and are partitioned up to create the private LUNS of 256MB slices for pool allocations

Dynamic Pools - Architecture
Supported RAID Levels and Minimum Drive Count
• Dynamic Pools support the following RAID levels – RAID 5 | RAID 6 | RAID 1/0
• Different size drives can be mixed in a Dynamic Pool
• Minimum number of drives when creating a Pool:
RAID Level
RAID Width Minimum Number of Drives
How it is Calculated
RAID 5 4+1 6 (4+1)+ 1 Extra Drive RAID 6 4+2 7 (4+2)+ 1 Extra Drive
RAID 1/0 1+1 3 (1+1)+ 1 Extra Drive

Dell EMC Unity Thin Clones
• A Thin Clone is a read-write copy of a Thin Block resource which shares blocks with the parent object
– Includes LUNs, LUNs within Consistency Groups, and VMFS Datastores – Supported on all Dell EMC Unity models and Dell EMC UnityVSA (Professional
and Community version)
• All data services remain available on the parent objects on creation of the Thin Clone
– Create Thin Clone from Attached Read-Only or Unattached Snapshots
• User is be able to: – Create, refresh, view, modify and delete a Thin Clone
© Copyright 2017 Dell Inc. 32
Dell EMC Unity Thin Clones
Benefits
• Space savings – Space consumed by Thin Clone is only changed data – Reduce the cost for application test and development environments
• Can apply data services to Thin Clones: – Host Access – Host I/O Limits (QoS) – Manual/Scheduled Snapshots – Replication
› Creates a full LUN copy on the target side Dell EMC Unity Data Protection & Copy Management Options Wed @ 12:00PM
For more information:
© Copyright 2017 Dell Inc. 33
Snapshot Shipping
• Extends Asynchronous Replication to support shipping of snapshots along with the primary storage resource
• Both user-created and scheduled snapshots can be replicated
• Supported for all primary resources that support Asynchronous Replication: – LUNs – Consistency Groups – File Systems – VMware VMFS and NFS Datastores
© Copyright 2017 Dell Inc. 34
Snapshot Shipping
Benefits
• Destination can have a different retention policy – Extended retention periods for compliance (i.e. IRS, HIPAA, etc.)
• Cost Efficient – Replicated snapshots can be deleted from the source system
• Resiliency – Provides the user the ability to store the snapshots in a different fault
