• Dell EMC PowerEdge Servers
• Intel Broadwell Processors
• Addresses more use cases –
storage heavy, graphics

• Data protection requirements include more than
backup and recovery
• Multiple data protection solutions are causing silos
and costly management
• Rapid growth of virtualization is causing
VM sprawl
• Application administrators are responsible
for the protection of their applications
Virtualization challenges
Local protection options

• Defines the number of hosts,
disk or network failures a
storage object can tolerate.
• For “n” failures tolerated,
“n+1” copies of the object are
created and “2n+1” host
contributing storage are
required!

Overview
• Intelligent grouping of hosts
across location (racks/rooms)
• Ensure that data replicas are
stored in different fault domains
Benefits
• Data integrity is maintained
even in the event of the failure
of a rack or room
• A copy of the data is always
stored in a different fault domain
Fault domains
Dell - Internal Use - Confidential24
OVERVIEW
• Single parity protection (RAID5-like) and double parity
protection (RAID6-like). Single parity can tolerate 1 failure and
dual parity can tolerate 2 failures
• Single parity will be 3+1 and requires minimum
of 4 nodes
• Dual parity will be 4+2 and requires minimum
of 6 nodes
• Dynamically change the config to other parity
levels through SPBM
• Parity is distributed across nodes
• All-flash only
BENEFITS
• >30% storage saving for FTT=1 (RAID1 vs. RAID5)
• >50% storage saving for FTT=2
Erasure codingProvide storage efficiency for FTT=1 and FTT=2

Disaster recovery protection options
Dell - Internal Use - Confidential27
OVERVIEW
• Data protection and disaster recovery within the same
site and across sites
• Data center migration
• Replication engine for VMware Site Recovery Manager Air™
and VMware vCloud Air™ Disaster Recovery
• Replication engine for VMware Site Recovery Manager
BENEFITS
• Integration with vSphere Web Client eases administration
and monitoring
• Protect nearly any virtual machine regardless of Operating System
(OS) and applications
• Only changes are replicated, which improves efficiency
and reduces network utilization
• Recovery Point Objective (RPO) configurable from 5 minutes
to 24 hours on a per-virtual machine basis
vSphere Replication (VDP) – included in VxRailIntegrated replication
But what if we need
more granularity,
optimized WAN performance,
one-to-many replication, … ?
Dell - Internal Use - Confidential29
Advanced replication with RecoverPoint for VMs
No single point of failure
• Each VM can be replicated by any vRPA
Minimizing bandwidth costs
• Utilize RecoverPoint Compression & Deduplication
• Flexible deployment
• vRPAs can be deployed on separated ESXi
clusters than the protected VMs
Fast recovery time
• No data copying when accessing image
“DVR-like” roll-back
• Fastest image access to the latest point in time
Multi-copy protection
• Concurrent local & remote copies
Dell - Internal Use - Confidential30
Local replication
• Target on adjacent appliance
• Scale-up or scale-out
Remote replication
• To any target
(Dell EMC VxRail Appliance or other)
• ROBO DR
Data migration (onboarding to Dell EMC VxRail)
• From any storage
• At VM Level

Enables zero RPO with synchronous replication
Dynamically switch between Sync & Async
based on available bandwidth
Support vMotion of protected VMs and vRPAs,
and Storage vMotion of protected VMDKs
Support both RDMs and VMDKs

VMware Data Protection (VDP) – included in VxRail
OVERVIEW
• Integrated backup and restore capability managed
within vCenter
• Encrypted and compressed
applications for offsite backup
• VM, application and file level restore
BENEFITS
• Backup and recovery of VM’s is
point and click using existing tools
• Seamlessly move backups offsite
for retention
• Application aware
• Easily restore VMs or even individual files
Integrated backup and recovery
Dell - Internal Use - Confidential37
VDP considerations
Scale limits
• 200 VMs per VDP appliance
• Up to 8TB1 of local post-deduplication storage
• Can be expanded by integrating existing or new Data Domain appliances1
Application integration
• Microsoft SQL, Exchange, and SharePoint agents
• What about Linux, Oracle, LAMP stacks
Physical system support?
• We want everything to be virtualized, but there’s always an exception
Reporting?
• Success, failure, protection coverage—what about broader capacity management, usage
trending, recoverability analysis?
