Active-Passive Data Center Design?


UNIFIEDNETWORK

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 RecoveryBackup and Offsite Replication

High AvailabilityApplication restart with limited disruption

Continuous AvailabilityApplication continues with no disruption (Zero Downtime)


Planned Vs. Unplanned DowntimeWhat 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

Distributed Virtual Volume

• 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.

VPLEX Witness Cluster Arbiter

• Coordinates seamless failover

• Enables longer distance for stretched server clusters

VPLEXWITNESS

• 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 DowntimeLive 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
