The new Opteron 6300: Finally Tested!by Johan De Gelas on February 20, 2013 12:03 AM EST
Unfortunately, the Intel R2208GZ4GSSPP is a 2U server, which makes it hard to compare it with the 1U Opteron "Interlagos" and 1U "Westmere EP" servers we have tested in the past. We will be showing a few power consumption numbers, but since a direct comparison isn't possible, please take them with a grain of salt.
Intel's Xeon E5 server R2208GZ4GSSPP (2U Chassis)
|CPU||Two Intel Xeon processor E5-2660 (2.2GHz, 8c, 20MB L3, 95W)|
|RAM||64GB (8x8GB) DDR-1600 Samsung M393B1K70DH0-CK0|
|Motherboard||Intel Server Board S2600GZ "Grizzly Pass"|
|BIOS version||SE5C600.86B (01/06/2012)|
|PSU||Intel 750W DPS-750XB A (80+ Platinum)|
The Xeon E5 CPUs have four memory channels per CPU and support DDR3-1600, and thus our dual CPU configuration gets eight DIMMs for maximum bandwidth. The typical BIOS settings can be found below.
Not visible in the above image is that all prefetchers are enabled in all of the tests.
Supermicro A+ Opteron server 1022G-URG (1U Chassis)
Two AMD Opteron "Abu Dhabi" 6380 at 2.5GHz
Two AMD Opteron "Abu Dhabi" 6376 at 2.3GHz
Two AMD Opteron "Bulldozer" 6276 at 2.3GHz
Two AMD Opteron "Magny-Cours" 6174 at 2.2GHz
|RAM||64GB (8x8GB) DDR3-1600 Samsung M393B1K70DH0-CK0|
|Internal Disks||2 x Intel MLC SSD710 200GB|
|Chipset||AMD Chipset SR5670 + SP5100|
|BIOS version||v2.81 (10/28/2012)|
|PSU||SuperMicro PWS-704P-1R 750Watt|
The same is true for the latest AMD Opterons: eight DDR3-1600 DIMMs for maximum bandwidth. You can check out the BIOS settings of our Opteron server below.
C6 is enabled, TurboCore (CPB mode) is on.
ASUS RS700-E6/RS4 1U Server
Two Intel Xeon X5670 at 2.93GHz—6 cores
Two Intel Xeon X5650 at 2.66GHz—6 cores
|RAM||48GB (12x4GB) Kingston DDR3-1333 FB372D3D4P13C9ED1|
|BIOS version||1102 (08/25/2011)|
|PSU||770W Delta Electronics DPS-770AB|
To speed up benchmarking, we tested the Intel Xeon and AMD Opteron system in parallel. As we didn't have more than eight 8GB DIMMs, we used our 4GB DDR3-1333 DIMMs. The Xeon system only gets 48GB, but this isn't a disadvantage as our highest memory footprint benchmark (vApus FOS, 5 tiles) uses no more than 40GB of RAM. There is no real alternative as our Xeon has three memory channels and cannot be outfitted with the same amount of RAM as our Opteron 6300 or Xeon E5 system (four channels).
Common Storage System
For the virtualization tests, each server gets an Adaptec 5085 PCIe x8 card (driver aacraid v1.1-5.1 b 469512) connected to six Cheetah 300GB 15000 RPM SAS disks (RAID-0) inside a Promise JBOD J300.
All vApus testing is done on ESXi vSphere 5--VMware ESXi 5.1. All vmdks use thick provisioning, independent, and persistent. The power policy is "Balanced Power" unless otherwise indicated. All other testing is done on Windows 2008 Enterprise R2 SP1. Unless noted otherwise, we use the "High Performance setting" on Windows 2008 R2 SP1.
Both servers are fed by a standard European 230V (16 Amps max.) powerline. The room temperature is monitored and kept at 23°C by our Airwell CRACs. We use the Racktivity ES1008 Energy Switch PDU to measure power consumption. Using a PDU for accurate power measurements might seem pretty insane, but this is not your average PDU. Measurement circuits of most PDUs assume that the incoming AC is a perfect sine wave, but it never is. However, the Rackitivity PDU measures true RMS current and voltage at a very high sample rate: up to 20,000 measurements per second for the complete PDU.
