Addressing Meltdown/Spectre in VMmark

Addressing Meltdown/Spectre in VMmark

This post was originally published on this site —The recently described Meltdown/Spectre vulnerabilities have implications throughout the tech industry, and the VMmark virtualization benchmark is no exception. In deciding how to approach the issue, the VMmark team’s goal was to address the impact of the these vulnerabilities while maintaining the value and integrity of the benchmark. Applying the full set of currently available Meltdown/Spectre mitigations is likely to have a significant impact on VMmark scores. Because the mitigations are Read more […]

SQL Server Performance of VMware Cloud on AWS

SQL Server Performance of VMware Cloud on AWS

This post was originally published on this site —In the past, I’ve always benchmarked performance of SQL Server VMs on vSphere with “on-premises” infrastructure.  Given the skyrocketing interest in the cloud, I was very excited to get my hands on VMware Cloud on AWS – just in time for Amazon’s AWS Summit! A key question our customers have is: how well do applications (like SQL Server) perform in our cloud?  Well, I’m happy to report that the answer is great! VMware Cloud on AWS Environment First, here Read more […]

ESX IP Storage Troubleshooting Best Practice White Paper

ESX IP Storage Troubleshooting Best Practice White Paper

This post was originally published on this site —We have published an ESX IP Storage Troubleshooting Best Practice white paper in which we recommend vSphere customers deploying ESX IP storage over 10G networks to include 10G packet capture systems as a best practice to ensure network visibility. The white paper explores the challenges and alternatives for packet capture in a vSphere environment with IP storage (NFS, iSCSI) datastores over a 10G network, and explains why traditional techniques for capturing packet traces on 1G networks will suffer Read more […]

Performance of SQL Server 2017 for Linux VMs on vSphere 6.5

This post was originally published on this site —Microsoft SQL Server has long been one of the most popular applications for running on vSphere virtual machines.  Last year there was quite a bit of excitement when Microsoft announced they were bringing SQL Server to Linux.  Over the last year Microsoft has had quite a bit of interest in SQL Server for Linux and it was announced at Microsoft Ignite last month that it is now officially launched and generally available. VMware and Microsoft have collaborated to validate and support Read more […]

Skylake Update – Oracle Database Performance on vSphere 6.5 Monster Virtual Machines

Skylake Update – Oracle Database Performance on vSphere 6.5 Monster Virtual Machines

This post was originally published on this site —We were able to get one of the new four-socket Intel Skylake based servers and run some more tests. Specifically we used the Xeon Platinum 8180 processors with 28 cores each. The new data has been added to the Oracle Monster Virtual Machine Performance on VMware vSphere 6.5 whitepaper. Please check out the paper for the full details and context of these updates. The generational testing in the paper now includes a fifth generation with a 112 vCPU virtual machine running on the Skylake based server. Read more […]

Episode 3: Performance Comparison of Native GPU to Virtualized GPU and Scalability of Virtualized GPUs for Machine Learning

Episode 3: Performance Comparison of Native GPU to Virtualized GPU and Scalability of Virtualized GPUs for Machine Learning

This post was originally published on this site —In our third episode of machine learning performance with vSphere 6.x, we look at the virtual GPU vs. the physical GPU. In addition, we extend the performance results of machine learning workloads using VMware DirectPath I/O (passthrough) vs. NVIDIA GRID vGPU that have been partially addressed in previous episodes: Episode 1: Performance Results of Machine Learning with DirectPath I/O and GRID vGPU Episode 2: Machine Learning on vSphere 6 with NVIDIA GPUs Machine Learning with Virtualized GPUs Performance Read more […]

Updated – SQL Server VM Performance with vSphere 6.5, October 2017

Updated – SQL Server VM Performance with vSphere 6.5, October 2017

This post was originally published on this site —Back in March, I published a performance study of SQL Server performance with vSphere 6.5 across multiple processor generations.  Since then, Intel has released a brand-new processor architecture: the Xeon Scalable platform, formerly known as Skylake. Our team was fortunate enough to get early access to a server with these new processors inside – just in time for generating data that we presented to customers at VMworld 2017. Each Xeon Platinum 8180 processor has 28 physical cores (pCores), Read more […]
