Simply Spectacular Virtualization with 4P Six-Core AMD Opteron™ Processor-based Systems
Posted by Margaret Lewis in 4:40 PM
Loading ...When I was attending VMworld in September, one of the most frequently asked question was “how do I decide whether to use 2P Intel Xeon 5500 processor-based servers or 4P Six-Core AMD OpteronTM processor-based servers for virtualization?” Over the past few weeks I have done a lot of research and put together a solid picture of where a 4P server can provide an amazing amount of value and efficiency.
Low and behold – I was not the only person working on this thought thread. We recently sent Johan De Gelas with AnandTech a 4P Six-Core AMD Opteron processor-based system. And in his review, “Expensive Quad Sockets vs. Ubiquitous Dual Sockets,” Johan focuses on some interesting points on the same topic (which my colleague John Fruehe discusses on the @Work blog as well). While he compares a number of workloads on 2P servers versus 4P servers- my interest was drawn to the section where Johan discusses one of my most favorite topics – virtualization (surprise, surprise).
In my research I have been taking a look at the pricing of 2P and 4P servers with larger memory configurations. Here is a snapshot of system costs using processors with similar specifications. Note how steeply the system price climbs for the 2P servers as the memory configurations grow.

Johan came to a similar conclusion ”A very large database or virtualization consolidation scenario requiring more than 72GB of RAM will probably push you towards the quad Istanbul – once you need more than 64-72GB, memory gets really expensive on the Intel dual socket platform. There are two reasons for this: 8GB DIMMs are five times more expensive than 4GB DIMMs, and DDR3 is still more costly than DDR2 (especially in large DIMMs).”
OK – this is a compelling cost message. But what about performance? Johan gives two examples of performance – current VMmark scores with systems that have memory configurations ranging from 64GB to 128GB, and vApus Mark I, their own in-house developed virtualization benchmark, designed to measure the performance of “heavy” performance-critical applications and done in cooperation with the Sizing Servers Lab.
For performance details, latest results, and system configurations see http://www.vmware.com/products/vmmark/results.html.
So compelling performance - and more importantly – very compelling price/performance.
I did one other exercise during my research. Instead of just comparing server to server – I took a look at comparing a 42U rack of 2P servers versus a 42U rack of 4P servers. Using the system costs from the example above here is another snap shot

| Total Number of Processors |

| Total Number of Cores |

| Cost of servers with 64GB RAM |
$152,712 |
$161,200 |
| Cost of servers with 96GB RAM |
$334,362 |
$171,560 |
| Cost of servers with 128GB RAM |
$656,082 |
$181,920 |
The price difference of servers to fill a 42U rack is less than $10,000 when comparing 2P and 4P servers with 64GB of RAM – and over $400,000 more for 2P with 128GB of RAM compared to similarly configured 4P servers.
So the take away from my research – 4P servers running Six Core AMD Opteron processors provide the cores, memory and price to achieve simply spectacular virtualization! And, as I noted, to get some additional insights on the same topic, check out my colleague John Fruehe’s recent blog “AMD Opteron Processor – Delivering True Value, Not Just Benchmarks.”

Simply Spectacular Virtualization – Istanbul Edition

(4 votes, average: 3.50 out of 5)Simply Spectacular Virtualization – Istanbul Edition
With the introduction of Six-Core AMD OpteronTM processor (codenamed “Istanbul”), there is now enough public information on the web to take a closer look at configurations and pricing of Six-Core AMD Opteron processor-based systems (”Istanbul”) and Quad-Core Intel Xeon processor-based systems (”Gainestown”) that have posted top VMmark scores.
Before I dive into the comparisons, let me acknowledge that I’m sure a lot of people will call “foul” with this comparison since the Intel Xeon 5570 processor-based system uses 96GB of memory and the AMD Opteron 2435 processor-based system uses 64GB of memory. Let me remind you that these are the “VMmark configurations” which are submitted by OEMs.
Here is the comparison of VMmark configurations for similar models of HP ProLiant 2P/2U G6 systems that were priced on the HP ProLiant Server web site on Friday, June 5, 2009. Each system had the processors and memory configuration as listed on VMmark disclosure documents along with the default disk controller, one 146 GB hard drive, and the default hardware warranty.

The HP ProLiant DL385 G6 running Six-Core AMD Opteron processors (”Istanbul”) offers the same cost per VM as the ProLiant DL380 G6 running Intel Xeon 5570 model with a system cost that is about 1/3 less. It should be noted that the DL385 is using a standard processor model as opposed to the high-end processor model used by the DL380.
You can configure the AMD technology-based DL385 with a considerably cheaper 64GB configuration using 16 x 4GB DIMMs. This results in a system cost that is almost 2/3 less than the Intel configuration using 12 x 8GB DIMMs. Assuming that there is about 10% performance difference compared to the 8 x 8GB AMD processor-based configuration with this alternate memory configuration, the estimated cost per VM would be $115. Mind you: the 10% performance difference here is not a measured result – it is more or less an educated guess of what we might see if we changed our memory configuration from 8 x 8GB to 16 x 4GB. But it shows that shows that it should be possible to get an even better cost per VM and overall system cost using AMD technology-based systems. It should be noted that the DL380 does not offer a cheaper 96GB memory configuration – the configuration listed is the cheapest.
In order to show a more comprehensive comparison I have done a hypothetical 64GB comparison (listed below). I have selected a comparable memory configuration for DL380 system using the HP DDR3 Memory Configuration Tool to decide the best configuration for the DL380 system due to the complexities surrounding configuring systems with Intel Xeon 5570 3 memory channel architecture. The recommendation from HP for virtualization was to 8 x 8GB DIMMs. For the DL385 I show both 8 x 8GB and 16 x 4GB memory configurations since both of these configurations are valid and result in well performing systems. I have also listed the cost per VM when running 10, 20, 40, and 60 VMs per system. Keep in mind the average number of VMs per server may be closer to 10. For reference, responses to SearchDataCenter.com’s 2008 Purchasing Intentions Survey reveals that only 5% of respondents are running more than 25 VMs on a server – 61% are running less than 10 VMs per server and 33% are running 10 to 25 VMs per server.

In both comparisons in this blog it is obvious that the Six-Core AMD Opteron processor (”Istanbul”) continues AMDs focus on producing a processor that offers a balance of performance, power and price. A similar comparison of VMmark systems and price/performance can be found on SolutionOrientedBlog.
