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 →
Earlier, we had blogged about Oracle RAC on VMware Virtual SAN Hybrid which is VMware software-defined storage solution for hyper-converged infrastructure and is available at Oracle RAC on Hybrid VSAN
In this blog post, we would like give you a glimpse of the “Oracle 12c OLTP workloads on VMware All Flash Virtual SAN 6.2”.
As some of you may know, in VMware Virtual SAN 6.2, we introduced a suite of new features for data integrity and space efficiency including Checksum, Erasure Coding, Deduplication and Compression. Using these features we developed an architecture for deploying and running Oracle 12c OLTP and DSS workloads on VMware All Flash Virtual SAN 6.2.
Before going into some of the results, let’s take a look as to why it is compelling to deploy heavy IO Oracle workloads on a VMware Virtual SAN All Flash solution.
Extreme Performance – Virtual SAN is built into the vSphere kernel which optimizes the I/O path to provide excellent performance.
Built in Data Reduction Technologies – Deduplication, Compression and Erasure Coding reduces data footprint and lowers cost, both capex and opex, further lowering the TCO of the solution.
Availability for Business Critical Applications – Minimizes downtime with features like vMotion, vSphere HA, Virtual SAN Stretched Clustering.
Redundancy for Business Critical Applications – Provides high level of redundancy thereby avoiding single point of failures (SPOF) with features like Failure to Tolerate (FTT), Fault Domain
Business Critical Applications (BCA) are at the heart of an organization; their performance, availability and reliability are vital to the success of the business. Significant advances in hardware are far outpacing the performance requirements of even the most intensive business-critical applications, including Oracle Database.
VMware has kept pace with these hardware improvements by engineering significant performance advances in vSphere 6.0. Best Practices are key in ensuring that business SLA’s, uptime, QoS are met with when deploying Oracle on VMware vsphere.
Successful virtualization of any Business Critical Application (BCA) required best practices inculcated in every layer of the stack.
We are pleased to announce the updated version of the “Oracle Databases on VMware Best Practices Guide” which can be found in the below URL. Thanks to everyone who participated in this exercise
In this guide there are also references to other VMware and third-party documents which we encourage the reader to consult for better understanding of the topics discussed.
VMware has received confirmation that Microsoft has determined that the issue reported in this post is a Windows-specific issue and unrelated to VMware or vSphere. Microsoft is encouraging customers to follow the directions provided in Microsoft KB3125574 for the recommended resolution. All further updates will be provided directly by Microsoft through the referenced KB. This marks the end of further updates to this blog post.
I am removing reference to “VMware VMXNet3” in the title of this post to reflect Microsoft’s latest updates to their KB. Yes, the issue still exists when using VMXNet3 for VMs, but it no longer appears that this issue is specific to “VMXNet3” virtual network adapters.
We are still working with Microsoft to conduct a comprehensive Root-Cause Analysis, and we will provide further updates as new information (or a resolution) becomes available.
From May 17th to May 19th, SAP welcomed around 30,000 attendees to Orange County Convention Center in Orlando, Florida to its SAPPHIRE NOW conference and provided an overview on what’s new as well as what’s upcoming from SAP in 2016. As Bill McDermott, SAP CEO states during his keynote: “Run Live, Run Simple”!
Freely adapted from this motto, I am going to provide you an overview on what’s new form VMware in the SAP area to help SAP and it customers to make this motto real and what we have prepared and presented on our booth. Continue reading →
Since SAPHIRE 2016, SAP supports now also SAP HANA on vSphere 6 deployments for production workloads, see SAP Note 2315348 for details.
The support for vSphere 6 allows customers to increase the RAM to up to 4 TB (4080 GB) of existing virtual SAP HANA systems when migrated to vSphere 6 and allows to react on increased memory needs due to data growth or newly deployed SAP HANA scenarios and solutions.
Beside increased RAM sizes vSphere 6 supports also more vCPUs. Up to 128 vCPUs can now get configured and used by a single SAP HANA VM.
Supporting more physical compute resources inside a VM ultimately provides more “power” to a virtualized SAP HANA system – this alone is worth upgrading from a vSphere 5.5 to a vSphere 6.0 based SAP HANA environment. Beside this, all vSphere 6.0 features can get used as before with vSphere version 5.5. Continue reading →
Choosing the right availability configuration for your SQL Server on vSphere can be a bit confusing as there are more than a few options to choose from, questions such as: Should I use vSphere HA if i’m using AlwaysOn? What are the implications of running different availability configurations on vSphere, and what are the best practices?
This very popular guide called “Microsoft SQL Server on VMware vSphere Availability and Recovery Options” which outlines the availability options and best practices for SQL Server on vSphere and tries to answer these question, is now updated with the latest information.
This is the second blog of my SAP HANA on vSphere blog series and will provide information on SAP HANA on VMware vSphere compute resource sizing.
This blog does not describe how to perform the actual SAP HANA system RAM sizing. For this please refer to the SAP documentation. A good start is to read the sizing SAP HANA Sizing Approaches presentation, which describes the SAP HANA QuickSizer and ABAP SAP HANA sizing reports available for sizing SAP HANA systems. Also a good start is the Sizing Approaches for SAP HANA document. (Attention you may require a SAP SDN account to access the SAP HANA sizing documents).
CPU and RAM Sizing SAP HANA on VMware vSphere
Sizing SAP HANA is different from sizing a classical SAP application. Instead focusing on CPU resources, for SAP HANA memory is the focus and how many CPU resources are required to support a specific amount of RAM. Beside this, we have to consider the different CPU and RAM maximums of vSphere 5.5 and 6, as it defines the maximal size of a virtual SAP HANA VM. To make it even more complex, we have to take into account which workload (SoH or BWoH) will run on the selected SAP HANA system, which CPU and which HANA SPS version will get used, as different CPU socket to RAM ratios exist for all of these combinations.

Combining these allow designing complex applications.
For example using the vRealize Automation design canvas you can put together a multiple instance machine to deploy cluster nodes with an XaaS components to create shared disks and software components to install and configure the Operating System, and application layers.

In the first partwe looked at public, private and Hybrid Cloud and their characteristics. In this part we will look at the common characteristics of business critical applications. In the second part , we looked at how some of these characteristics relate to the different types of Cloud infrastructure. In this final part we will look at he lifecycle of a business critical application in the cloud and the conclusion. Continue reading →
