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

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

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
