VMworld 2016: VM and App Protection

Session: INF8939

4 Step Program for Success

  • Define – Gather requirements – RPO/RTO
  • Research and design – look at various technologies
  • Acquire and implement – Document
  • Test and operate – Continuous testing, continuous research

Disaster recovery and business continuity

  • DR is recovery of data
  • BC is the full business process of recoverying

Define Requirements

  • What are you  trying to protect? apps, VMs, DBs, etc.
  • What are you protecting against? data loss, data corruption, disaster, etc.
  • What is your RPO? zero, minutes, hours, days
  • What is your RTO?
  • How long do I need to keep data? retention policy, archiving, etc.

Protection Tiers

  • Tier 1 – mission critical
  • Tier 2 – Required for longer term business continuity
  • Tier 3 – Nice to have but not required

Tape Backup

  • Cheapest medium
  • RPO of hours to days
  • RTO – depends on how much data
  • Good for archival/long term retention

Hardware Snapshots

  • Snap/restore data in seconds from GB to TB
  • Application consistent storage snapshots – not needed for all VMs
  • Data on primary storage can be expensive

Array Replication

  • Async or sync
  • Only changed data sent
  • Flexible RPO options
  • RTO is based on how data is restored

Site Recovery Manager

  • Integrates with vSphere for site failover
  • Able to test and re-test
  • Requires array integration

Continuous Data Protection

  • Flexible RPO options
  • RTO based on amount of data
  • Only changed data sent

Disk-2-Disk

  • May be appliance or software based
  • Most  integrate with traditional backup
  • Integrates with CDP

Cloud/Hybrid

  • Typically continuous backup so low RPO
  • Backup and recovery limited by bandwidth
  • May have longer recovery times
  • Can take a long time to seed backups

vSphere Metro Cluster

  • Zero RPO/RTO (time to restart apps is  not zero)
  • Great for site protection
  • Layer 2 stretching
  • No application specific backup/restore

Fault Tolerance

  • Limited in supported vCPUs
  • Requires high bandwidth between hosts
  • Does not protect against OS/App failures

 

.Next 2016: Business Continuity for Tier-1 Apps

Presenters: Partha R (NTX), Mike McGhee (NTX), Ryan Sheldon (AMGEN)

Tier-1 apps are different for different customers. Could be ERP, EPOS, email, etc.

Need to be prepared for the worst: IT Productivity, recovery, end-user productivity, business disruption, lost revenue, etc.

Data protection requirements: RPO, RTO

Understand consistency: Application consistency (e.g. VSS). Most beneficial in the context of backup and restore.

Technologies: Application (Exchange DAGs, SQL AAGs, Oracle Dataguard), Hypervisor (hyper-v replica, vsphere replication), storage (infrastructure centric, Nutanix Data Protection)

What am I protecting? Application dependencies? One or multiple methods? How frequently do you backup and replicate? Sync vs. async?

Where does Nutanix native replication fit in?

Timestream – RTO of minutes, RPO of minutes

Cloudconnect – RTO hours, RPO hours

Async replication – RTO minutes, RPO minutes

Sync replication – RTO near-zero, RPO zero

  • Low performance impact
  • VM and application level consistency

Nutanix Async Replication

Nutanix Cloud Connect

  • Hybrid cloud solution from Nutanix

  • For archiving and backup
  • Easy to setup and manage
  • WAN optimized replication
  • Interop with Nutanix DR

Volume Groups with Async Replication

  • Exchange + iSCSI
  • MS SQL Clustering
  • Oracle RAC
  • Bare Metal

Consistency options: VSS

  • VMware Tools or Nutanix guest tools
  • Pre and post scripts for Linux

Consistency options: Consistency Groups

  • For a group of VMs and a consistent restart point

AMGEN

Manufacturing is key. They leverage Metro availability to provide high uptime. Customer set it up in about 10 minutes. With MA they can converge services like DNS, DHCP, etc. and save on licensing costs.

Nutanix:

What’s next: Metro Availability Witness coming out in Asterisk, which will automate site-failover.
