HP Offers the Right Compute for Scale-up x86 Workloads

A critical rule of thumb to live by –especially in information technology—is  that one size does not fit all. This is especially true when you’re looking to deploy a scale-up x86 server to meet your consolidation, data analysis or business processing needs. Depending on the type of workload being implemented, varying factors such as performance, scalability, reliability, efficiency and performance density are important and need to be factored into the equation. At HP, we are implementing a vision of providing a broad family of scale-up x86 servers that meet these diverse requirements.  

Looking for the optimal combination of breakthrough efficiency, performance and reliability?

In today’s hyper-connected world the explosion of workloads—mobility , social media, security, Cloud, multimedia as well as the Internet of Things (IoT) greatly impact the way we approach and get business done. 

HP Gen8 Server upholds world record in x86 2-processor performance: HP ProLiant ML350p

Guest blog written by Scott Cannon, HP Servers Marketing Manager

 

The HP ProLiant ML350p Gen8 Server’s recent performance on the SPECjbb2013 benchmark earned the #1 in the x86 2-processor server Java performance on critical-jOPS.

What criteria do you use in picking the optimal server for your workload?

Scaling up your virtualization solution on 8-socket HP ProLiant Servers

These days, when wearing my “Linux planner” hat, and with Virtualization being the “phrase that pays”, I’m often asked to help provide guidance on how to best take advantage of the technology included in our 8-socket HP ProLiant server offerings for Linux based virtualization solutions like Red Hat Enterprise Virtualization or Suse Linux Enterprise Server Xen (there’s a plethora of information out there about VMware ESX/ESXi 3.5.x and vSphere 4.0, so I’m not going to talk about that, this time around.)


The problem I’ve had, until recently, was providing actual – objective - data as a means to help illustrate my points.  For instance, I could not clearly illustrate how a snoop filter on the CPU interconnect can improve the linearity of the workload scalability in a virtualized environment (see Fig. 1).

I was unable to demonstrate benefits of the NUMA aware scheduler that the Linux kernel uses and how it does improve performance. (In figures 2 and 3, it’s represented by the improvement in average response times from the web-servers included in the workload) when your workloads run with memory interleaving disabled in the system BIOS – see Fig. 2. Unless, for support reasons, your application vendor explicitly tells you otherwise.

I also used to have a hard time explaining how and why to tune the Linux kernel for these systems. For instance, I only suspected how little (none) tuning of the host platform is required in order to drive pretty significant numbers of guests  (98) in these environments - see Fig. 4. But, if you engage in some very minor tuning activities of the network stack, how those very same workload performance results can be extended even further (to 256 guests) – see Fig. 5:


Fig. 4: The system has not been tuned beyond it's "out of the box" state.

As part of a joint documentation effort with Red Hat, all of the data collected has been brought together in a Reference Architecture document  - “Scaling RHEL 5.4 + KVM up to 256 Guests" available for free from Red Hat’s website.


We obviously picked the guest density to prove a point about the platform, however it’s worth mentioning that 256 guests does not represent the upper bound for the platform. It only represents where we thought the density went (far) beyond what is reasonable to expect in a production environment this day in age.
