Performance Unplugged: vCenter Performance

Welcome to a new video series I’ve titled “Performance Unplugged”

In this video series, I’ll showcase a number of talented performance gurus and cover commonly asked questions and topics. Performance of the Software-Defined Datacenter should no longer be a concern for customers and we’ll explain why. Links to the latest information pertaining to the topic will also be provided.

Reference Architecture for building a VMware Software–Defined Datacenter

The latest in our series of reference architectures is now available. This is an update to the previous version which brings in additional products and covers the vCloud Suite 5.8 release.

This reference architecture describes an implementation of a software-defined data center (SDDC) using VMware vCloud® Suite Enterprise 5.8, VMware NSX™ for vSphere® 6.1, VMware IT Business Management Suite™ Standard Edition 1.1, and VMware vCenter™ Log Insight™ 2.0 to create an SDDC. This SDDC implementation is based on real-world scenarios, user workloads, and infrastructure system configurations. The configuration uses industry-standard servers, IP-based storage, and 10-Gigabit Ethernet (10GbE) networking to support a scalable and redundant architecture.

SAP SD Benchmark Results on vSphere Shows Near Native Performance

I wanted to highlight some recent work done using a 3rd party benchmark and audited certification process that helps to address concerns that virtual overhead is still unacceptable for enterprise applications.

Many of our customers are no longer focused on this negligible consumption by virtualization as VMware software defined infrastructures have continued to demonstrate they can meet all their application needs, but yet some people still ask for this information.

SAP provides a test and certification methodology known as the Sales and Distribution (SD) Benchmark which provides several units of measurement, including Users and SAPS, that determines a hardware-independent score. This benchmark is run on both virtual and physical platforms and is well scrutinized before a certification number is issued.

There are two results I’d like to draw attention to:

  • Certification Number 2014043 (11/7/2014) by Dell/VMware – 9400 Users, 51400 SAPS
  • Certification number 2014017 (5/5/2014) by Dell – 10,253 Users, 55970 SAPS

These two benchmarks were performed on the exact same hardware and application stacks with the only exception being that VMware ESXi 5.5 was used on the most recent test. From this we can easily demonstrate that this comprehensive application and database benchmark shows only a 8.3% difference in virtual versus physical performance.

Additionally it’s worth noting, for Monster VM fans, that the virtual machine was configured with 48x vCPU’s and 256GB of RAM.

The message here is that virtual performance of an enterprise’s most demanding applications is near that of physical and that the value provided from the virtual platform more than exceeds the minute cost. Be confident – virtualize everything!

Special thanks to our partner Dell and our performance gurus (Erik, Sebastian & Louis) at VMware for these efforts.

SQL Pass Conference completed

The vSphere PMM team in collaboration with the GTS team successfully completed VMware’s participation in the 3-day SQL Passs Summit conference at  the Washington State Convention Center in Seattle today.  We met with hundreds of successful SQL Server on vSphere customers to deliver the overall VMW message through the innovative use of the “Recharge Lounge”.  415 total attendees of the conference received a 5-min massage while they recharged their devices after they discussed their present or future success with SQL Server on vSphere.SQLPass1

VMware Sponsors “Recharge Lounge” at SQL Pass Conference

Following up on the momentum gained in the SQL Server on vSphere space last month as a result of the Elite SQL Server workshop, the vSphere PMM team arranged the sponsorship of the “Recharge Lounge” at the SQL Pass Conference in Seattle this week.  This specialized lounge not only allows conference attendees to recharge their devices but when they individually present a coupon, which they can only get from the VMware booth, the attendee will receive a 5 minute professional massage.   Not exactly what we do regularly but amazing effective in drawing in attendees to the VMW booth.  The stories are typical “We use vSphere for everything and it all works great” was a common theme.   We are on track to pass out 500 massage coupons in the 3 days of the conference.  This is fun!

VMware Virtual SAN Performance Testing – Part IV

Virtual SAN ObserverIn Part I, Part II and Part III of this blog post series, we reviewed methods of running benchmark tests on a Virtual SAN cluster using three different methods; synthetic I/O Tools such is Iometer, pre-created application I/O trace replay files available for download, or custom created application I/O trace replay. Once you are running benchmark testing, there will be the need to assess and analyze the performance results of your Virtual SAN cluster, and how they meet the needs of the target applications within your environment . In this post, we will review some key concepts in performing a performance analysis of your Virtual SAN solution.

VMware Virtual SAN Performance Testing – Part III

Virtual SAN ObserverIn the previous VMware Virtual SAN Performance Testing blog post we reviewed the benefits of running performance tests utilizing I/O trace files over synthetic workload tools such as IOmeter to more accurately characterize the performance of a Virtual SAN cluster. The VMware I/O Analyzer includes pre-created trace files of specific application profiles that allows you to quickly perform scale-out testing utilizing a mix of industry standard workloads But what if you want to characterize the performance of your existing vSphere virtualized environment within a new Virtual SAN configuration? This is were the use of custom I/O Trace replays can be useful. Continue reading
