Game Changing: Day 2 Enterprise Data Management Tasks with VMware NSX and vRealize Network Insight

As a Staff Partner Architect at VMware, I tend to look at our platform and products through a slightly different lens than some of my colleagues. Rather than focusing solely on our feature rich product sets and platform, I take a top down approach and identify which of these features are most interesting for mission/business critical deployments in a Software-Defined Data Center (SDDC).

VMware NSX is one of those game changing technologies which should interest application owners, database architects, CIOs, and of course network IT professionals. You can think of NSX as a network hypervisor, as such NSX administrators now have the ability to abstract and reproduce a complete set of layer 2 to layer 7 networking services. The ability to abstract and reproduce layer 2 to layer 7 networking services is certainly meaningful to network operations but what does it mean to enterprise architects? Why should our customers care, and why should CIOs care?  The answer is hair-pinning. Continue reading

Demo – Extended Oracle RAC across sites with VMware NSX

Our team has been working on building solutions for NSX with Business Critical Applications around Zero trust security, application mobility, operational efficiency, increased security and more .

In a previous post I published a demo about database cloning and enforcing dynamic security policies using NSX: http://blogs.vmware.com/apps/2016/04/dynamically-enforcing-security-on-a-hot-cloned-sql-server-with-vmware-nsx.html

In this blog post we are showcasing the ability to stretch an Oracle RAC solution in an Extended Oracle RAC deployment between multi-datacenter and using VMware NSX for L2 Adjacency.

With Extended Oracle RAC , both Storage and Network virtualization needs to be deployed to provided high availability, workload Mobility, workload balancing and effective Site Maintenance between sites. Continue reading

Critical Factors to consider when virtualizing Business Critical Applications: (Part 1 of 2)

Over the past few years, there has been significant acceleration in adoption of the VMware platform for virtualization of business critical applications. When vSphere 5 was introduced with its initial support for up to 32 vCPU many of the vertical scalability concerns that existed earlier were addressed. This has been increased to 64 processors with the later vSphere 5.x releases ensuring that more than 99% of all workloads will fit vertically.

Having personally worked in IT infrastructure for more than 20 years with a strong focus on implementing and managing business critical applications, I see a general reluctance from application owners to virtualize business critical applications. When virtualizing business applications there are many critical factors one should consider.  I seek to address the typical concerns of application owners about Virtualization with this multipart series on Virtualizing BCA.

DBA Guide to Databases on VMware

DBAs are being challenged to provide 24×7 database services to application owners with the flexibility and autonomy they expect while keeping the infrastructure as simple and economical as possible. Traditional databases running on fixed physical hardware are often over-sized, under-utilized, protected by complex, expensive clustering solutions, and require rigorous processes for version control and continued application compatibility. Meanwhile, organizations are increasingly virtualizing their enterprise applications in production and with a robust platform like VMware, mission-critical databases are no exception.

If knowledge is power, then knowing the capabilities of the underlying intelligent virtual infrastructure is certainly powerful for the DBA. Experienced Database Administrators (DBAs) recognize that virtualization unlocks capabilities that were impossible in physical environments.

Most importantly, the value of virtualization goes far beyond basic consolidation. Virtualizing database applications on vSphere can improve application Quality of Services (QoS), and accelerate application lifecycles while significantly reducing application costs. In this brand new DBA Guide to Databases on VMware, we discuss database performance on VMware, examine the general tasks for DBAs, and introduce VMware technologies and tools that assist DBAs in design, implement, test, operate, and maintain databases in a virtual environment.

The following topics are covered in detail in this guide:

  • DBA's roles and responsibilities
  • Understanding VMware performance
  • Design, Develop and Test databases on VMware
  • Migrating existing databases to VMware
  • Securing and running databases on VMware
  • Monitor and Troubleshoot database performance
  • Frequently asked questions from SQL and Oracle DBA's

Get your free copy of this hot-off-the-press DBA Guide to Databases here. And if you are a vSphere veteran you might want to share it with your DBAs. Don't forget to share your feedback and questions in the comments section of this blog.

Yes, Oracle is supported on VMware

Oracle is supported on VMware– apps and databases, both single instance and RAC. And plenty of customers have been virtualizing their Oracle workloads on VMware with confidence.  In case you’ve heard confusing opinions, let’s just review some facts.

From Oracle
Oracle’s support policy toward virtualization with VMware is accessible to subscribers of MyOracleSupport – Document ID #249212.1 which you can access here if you have a login. You can also read the actual Oracle support policy reproduced in Chad’s blog. In Nov 2010, Oracle added support for RAC on VMware which demonstrates Oracle’s continued commitment to provide customers with increasing flexibility and choice.

From VMware
In the past, some customers were concerned about a couple of apparent limitations in the Oracle support policy.  Specifically,
1.    Oracle has not certified any of its products on VMware
2.    Support is provided when the problem “can be demonstrated to not be as a result of running on VMware” and the fact that Oracle reserves the right to require reproduction of the problem on physical environments.
However, Oracle does not certify down to the infrastructure level (such as your Cisco switch or your Dell blade) so if you are running a certified OS on VMware, the situation is no different than running a certified OS on a blade server.  In the physical world, if Oracle support suspects that an issue is caused by your underlying hardware then you can be requested to reproduce on another host. And that is no different from the stance on virtualization with VMware.

While most customers understand these nuances, even those who had lingering concerns have been assured with the new VMware policy for Oracle support.  With this policy, VMware is providing an absolute commitment to support customers virtualizing Oracle on VMware vSphere.  If required, VMware will take ownership of the support request and ensure rapid resolution, in collaboration with the Oracle support organization as needed. Since VMware’s customers virtualize all types of Tier1 applications, there is no question that providing a seamless support experience is an area of expertise for VMware.

From Oracle & VMware partner, EMC
EMC’s recent article in the current issue (Mar/Apr) issue of Oracle magazine reinforces customer and partner confidence in virtualizing Oracle on VMware.  EMC also has a number of resources related to Oracle virtualization on VMware

From The Press
Oracle’s VMware Support Policy Like Jekyll and Hyde – TechTarget, Feb 2011
Oracle will now support Oracle RAC on VMware – TechTarget, Nov 2010

From Customers
Many of our customers are happily running production Oracle applications and databases on VMware vSphere.  The following are just a few examples of these customers. 
“When I talk to people about VMware virtualization, I tell them ‘don’t believe everything you think.’
We’re proving here at UBC that VMware is very viable. It works in production environments; it works for Oracle database servers, and everywhere in-between. VMware technology lets you architect a very reliable, very dynamic solution to your computing needs.”
– Michael Thorson, Director of Infrastructure, University of British Columbia

While these are just a few customer examples, the facts presented here should help clarify that Oracle is in fact supported on VMware.
