Active-Passive Data Center Design?

Automated Failover
Load Balancing across sites
Federated data repository
Continuous or High
Availability of applications
and data
Highly Virtualized
The Distributed Data Center

Why distribute your Data Center?
Increased Availability
– Both DCs serve Production workloads whilst providing
resiliency for the other.
Increased Asset Utilization
– Alternate DCs are expensive, normally with idle resources.
Increased Performance (Locality of Data Access)
– Data does not have to be read from the ‘Production’ site as
the same data is R/W accessible at both sites.

Disaster Recovery
Backup and Offsite Replication
High Availability
Application restart with limited
disruption
Continuous Availability
Application continues with no
disruption (Zero Downtime)

Planned Vs. Unplanned Downtime
What are you protecting against?
80% of downtime is planned downtime
Unplanned downtime can be split..
• 40% - Associated with OS, App and Db
• 25% - Operator error
• 20% - Hardware outages
• 8% - Environmental
• 7% - Network

But what about site availability?

Why is VPLEX unique?
VPLEX enables users to:
– Have the exact SAME information
▪ In two separate locations
• Accessible at the SAME time from both locations

Back-End Data Access
with VPLEX

VPLEX AccessAnywhere
• Hosts at both sites instantly access Distributed Virtual
Volume
• Synchronization starts at Distributed Volume creation
• WRITEs are protected on storage at both Site A and B
• READs are serviced from VPLEX cache or local storage.
• The loss of a storage array does not require a full site
failover.
Distributed Virtual Volumes

VPLEX Witness
Cluster Arbiter
• Coordinates seamless failover
• Enables longer distance for
stretched server clusters
VPLEX
WITNESS
• Provides 0 RTO for storage
changes or events

Application and Databases
with VPLEX

• Increased utilisation of physical
resources across sites.
• Failover of virtual machines between
sites in the event of a site disaster.

Ensuring Application
Availability
• VPLEX for RAC over distance
enables…
– Continuous Availability
– Simplified deployment and
management (removes reliance
on Oracle tool set)
– Managed as though it’s a single-
site implementation

Reduce Planned
Downtime
Live Migration
• Move applications seamlessly between
sites to reduce the need for planned
outages due to maintenance work on
storage, fabrics, servers or sites.
• Jointly validated VCE architecture using
Cisco Overlay Transport Virtualisation to
reduce impact of required stretched IP
subnets between sites.

Introducing EMC VPLEX
singledualquad
• What is it?
– A new federation HW and SW platform that can
extend storage beyond the boundaries of the data
center
– Located in the SAN to present hosts with a federated
view of EMC and non-EMC storage
• What is unique?
– Distributed coherent cache
– 1/2/4 I/O Engines To Scale Performance
– N-1 resiliency
– Architected for Global Apps
– Non-Disruptive Forever

What is RecoverPoint?
Continuously replicating data within SAN or between
SAN’s (via IP or FC) on a block level
Synchronously or asynchronously
With a journal of virtually unlimited point-in-time
snapshots
With compression and deduplication

Any Point-in-Time Recovery
Traditional recovery methods
Nightly backups, snapshots, mirrored images
plagued by time gaps, corruption
RecoverPoint
Recovery to any point in time
– Mount image to any host in SAN
– Full read/write access to image
without protection loss
Use recovered image for a variety of purposes
– Operational recovery
– Backup, testing, or decision support
– Reporting
