Protect your applications with vCloud Air Disaster recovery service

Earlier this year VMware released a new vCloud Air service for Disaster Recovery that brings business continuity protection for your vSphere on premise Virtual Machines:

  • A simple solution operated from the vSphere Web client and powered by vSphere Replication
  • Agile as it can scale up quickly with additional Cloud compute, storage, IPs and direct network connect capacity up to 1000 simultaneous replications to a vCloud Air Disaster Recovery enabled Virtual Data Center
  • Reduces physical infrastructure Capex
  • Variable term service options minimize Opex

Version 1 includes Disaster Recovery from on premise to vCloud Air, version 2 which is being rolled out in the different vCloud Air regions includes Multiple Point In Time recovery (ability to recover to one of the 24 previous replications) and Failing Back from vCloud Air to on premise.

These new capabilities as well as the possibility to testing a fail over offer new business continuity possibilities for some Enterprise Applications.

Once the vCloud Air Virtual Data Center networking setup is completed and the infrastructure Virtual Machines such as the domain controllers are replicated application Virtual Machines replications can be set up in a few minutes with a minimum Recovery Point Objective (RPO) of 15 minutes. This is technically accomplished with tracking changes and replicating only the latest deltas. Continue reading

Database-as-a-Service (DBaaS): Reference Architecture with VMware and Tintri

Database-as-a-Service (DBaaS) is a real-world example of cloud computing that delivers databases and database applications through self-service portals without IT intervention. Providing multiple copies of relational database servers for testing and development is traditionally a complex operation that involves the combined efforts of multiple teams and the creation of custom scripts. Yet the ability to quickly provision instances of Oracle and SQL Server databases can reduce the time to create, test, deliver, and deploy new applications.

A study of DBAAS with VMware vRealize Automation (vRA), Tintri storage done by VLSS highlights the capabilities of these platforms to do this efficiently and in an automated manner. The DBaaS reference architecture is only useful if end-users can deploy a catalog of VMs under varying conditions and workloads. These test results highlight three accomplishments in the vRA DBaaS reference architecture with Tintri.

Oracle, VMware and Extended Distance Oracle Real Application Clusters on vSphere Metro Storage Cluster

Oracle, VMware and Extended Distance Oracle Real Application Clusters on vSphere Metro Storage Cluster

Nowadays a high availability cluster (for any kind of application) in a single data center is almost not enough to ensure the kind of availability a Mission Critical Application needs which support revenue generation.

Typical issues plaguing a data center may include local power outage, airplane crash, server room flooding etc.


Do we have a solution?


THE answer: a “Stretched” Cluster, or one that is distributed between multiple sites , as long as the distance between them is within 100kms / satisfy 5ms Round Trip Latency time requirement.

This architecture best fits especially in regards to distance, latency, and degree of protection it provides.

Site separation is great protection for some local disasters as mentioned above but not all. Disasters such as earthquakes, hurricanes, and regional floods may affect a much greater area.

For comprehensive protection against regional disasters including protection against corruptions, Oracle Data Guard and VMware Site Recovery Manager (SRM) can be combined with Extended distance Oracle RAC on vSphere Metro Storage Cluster, giving us both a Disaster Avoidance and a Disaster Recovery Solution.

Harnessing the Power of Storage Virtualization and Site Recovery Manager to Provide HA and DR Capabilities to Business Critical Databases – VAPP4634

Harnessing the Power of Storage Virtualization and Site Recovery Manager to Provide HA and DR Capabilities to Business Critical Databases – VAPP4634

How do you simplify and improve availability of your Extended distance Oracle Real Application Cluster using vSphere Metro Storage Cluster (vMSC) ?

Storage Virtualization, both host based and appliance based, can pave the way for increased ease of configuration and improved availability of your cluster based applications. vMSC features including vMotion, HA, DRS and FT as well as extended distance Oracle Real Application Clusters (RAC) are greatly simplified, and in some cases, made possible through the use of storage virtualization technologies such as EMC VPLEX, Netapp Metro Cluster, IBM SVC, HP 3PAR Peer Persistence , VMware vSAN or Oracle Automatic Storage Management (ASM) disk groups.

Site Recovery Manager with Oracle Data Guard can provide the much needed Disaster Recovery component thereby providing a complete HA and DR solution to Business Critical Databases

See where and how virtualized storage provided by above storage virtualization vendors and ASM are most effectively used to help protect your business critical applications virtualized on vSphere.

See how one Global 1000 company used storage virtualization to achieve 0 second RPO and 5 second RTO.

Details on the solution will be discussed in detail at VMworld 2015 Barcelona in session VAPP4634:

Virtual Volumes: A game changer for operations of virtualized business critical databases

This is first of a series of posts on deploying vSphere Virtual Volumes for Tier 1 Business Critical Databases. Although this article is written with a focus on Oracle databases, much of this discussion holds good for any Mission critical application.

Business critical databases are among the last workloads virtualized in enterprises, primarily because of the challenges that they pose with growth and scale. Typically the low hanging fruits are virtualizing the Development, Testing/QA, Staging databases after running a successful POC and then moving on the big guy’s i.e. the Production databases.

There are many common concerns about virtualizing business critical databases that inhibit and delay virtualization of these workloads:

  • Business critical virtualized databases need to meet strict SLAs for performance and storage has traditionally been the slowest component
  • Databases grow quickly, while at the same time there is a need to reduce backup windows and their impact on system performance.
  • There is a regular need to clone and refresh databases from production to QA and other environments. However, the size of the modern databases make it harder to clone and refresh data from production to other environments
  • Databases of different levels of criticality need different storage performance characteristics and capabilities.
  • There is a never-ending debate between DBAs and Systems administrators regarding filesystems VS raw devices and VMFS VS RDM. These are primarily due to some of the deficiencies that existed in the past with virtualization.
