Is Your Data Protected?
DATA
AVAILABILITY
& INTEGRITY

• Local or Smaller Issues – Redundancy
• Regional or Larger Issues – Disaster Recovery Plan
• Security Breach/Attacks – Falling Back to the Last Known Good Data Status

3 Milestones to Ensure Business Continuity
MINIMIZE DOWNTIME MINIMIZE DATA LOSS

• Redundancy – High Availability (HA) with Synchronous Mirroring
• Disaster Recovery Plan – Disaster Recovery (DR) Based on Asynchronous
Replication to Remote Destination (> 250km)
• Falling Back to the Last Known Good Data Status – Backup, Snapshot
5
Business Continuity Principles
MINIMIZE DOWNTIME MINIMIZE DATA LOSS

• Storage system vendors provide HA, DR and Snapshot mechanisms
• But what if you have more than one vendor or you are not using or
planning to use enterprise storage (e.g. JBODs)?
• Compatibility
• Costs
• Service Levels (SLAs)
• Management

Diverse Technologies are Available (1/2)
…

• Hyperconverged and vendors provide HA, DR and Snapshot mechanisms
• Software vendors offer point solutions for each technology
• But what if you need more than one server-virtualization solution or you
have bare metal operating systems?
• Compatibility
• Costs
• Service Levels (SLAs)
• Management

High Availability with
Synchronous Mirroring
9

Zero downtime, Zero touch for Local
& Stretched / Metro Clusters
• Data in two places, eliminates
storage as a single point of failure
• Enhances survivability using
physically separate nodes
• Updates distributed copies
simultaneously
• No scripting or manual intervention
High Availability with Synchronous Mirroring

• Zero Downtime
• Active/Active failover
• No Application disruption
• Zero Touch Failover & Failback
• Completely Automated
• Live maintenance (upgrades &
migrations)
• Lowest TCO
• Supports different storage
environments on each side

Zero downtime, Zero touch for Local
& Stretched / Metro Clusters
• 3-Way Synchronous Mirroring for
enhanced Data Resiliency
• Full Automatic Resynchronization
and Fallback after Failover
• Not needed, but optional Witness
available
• Fully transparent to applications
Synchronous Mirroring – Even More

Disaster Recovery based on
Asynchronous Replication
14

Update distant copies without
impacting local performance
• Ideal for disaster recovery & remote
data center migration
• Standard IP-based links
• Optimizes bandwidth via compressed,
multi-stream transfers & QoS
• 1-many, many-to-1, many-to-many
• Bi-directional
• Test readiness non-disruptively
Disaster Recovery with Asynchronous
Replication

• Any Distance
• Applications do not
have to wait
• Any Destination
• Including Cloud
• Lowest TCO
• Supports different
storage environments
on each side

Expedite central site restoration • Reverses direction of replication
from the disaster recovery (DR)
site to the primary datacenter
• Universal coverage for
heterogeneous scenarios
• Same automated process
for virtual & physical systems
• Integrated with 3rd party tools, e.g.
VMware SRM
Asynchronous Replication –
Advanced Site Recovery

Falling Back to the Last Know
Good Data Status –
Backup, Snapshot and CDP
18

Capture point-in-time images
19
• Recover quickly at disk speeds to
known good state
• Differential and full clones
• Thin provisioned
• Read / writeable
• Trigger via VSS
• Snap from premium storage to
lower cost equipment
• Eliminate back-up window
• Provide “live” copy for analysis,
development & testing
Snapshots / Backups

Return to any point-in-time without
taking explicit snapshots/backups
20
• Restore arbitrary point-in-time
within a 14 day period
• Logs and timestamps all I/Os
to the selected virtual disks
• No need to quiesce or
interrupt applications
• No host agents required
• Easy to enable and revert from
• Create known-good restore points
Fall back to the Last Known Good Data with
Continuous Data Protection (CDP)

Close to Zero RPO and Fastest RTO with CDP
Backup
Snapshot
CDP

Fallback to the last good data status
with point-in-time images
22
• Complement each other
• Close to zero RPO and fastest RTO
• Differential and full clones which are
read / writeable
• Either application independent or
trigger able (e.g. via VSS, data points)
• Eliminate back-up windows
• Provide “live” copy for analysis,
development & testing
