Dell PowerEdge R815 Benchmarked Configuration

CPU Four Opteron 6174 at 2.2GHz
RAM 16 x 4GB Samsung 1333MHz CH9
Motherboard Dell Inc 06JC9T
Chipset AMD SR5650
BIOS version v1.1.9
PSU 2x Dell L1100A-S0 1100W

The R815 is a very compact design: six fans in the middle of the chassis pull the cool air across the four Opteron socket and 32 DDR3 DIMM slots. Two risers offer two full height PCIe x8 slots each.

Two half-height PCIe x4 slots are also available. The server contains six drive bays, all in 2.5 inch format.

The DELL server line distinguishes itself with an LCD display that allows you to read system alerts and boot-up options. The dual internal SD modules are unfortunately still only 1GB and thus only suited for ESXi. The 1100W hot-pluggable PSU are the only available PSUs. The entire front with disk bays can slide forward to give easy access to the first row of CPU sockets and DIMM slots.

AMD and Dell also confirmed that you will be able to upgrade this server with the next generation "Bulldozer" CPUs.

    The word you're looking for is "authentication". Is a simple spell check so much to ask? Reply

    Great article. I suggest to include some HPC benchmarks other than STREAM. For instance, DGEMM performance would be interesting (using MKL and ACML for Intel and AMD platforms). Reply

    One thing I would like to point out is that most of the customers I work with use VMWare in an enterprise scenario. Failover/HA is usually a large issue. As such we usually create (or at least recommend) VMWare clusters with 2 or 3 nodes. As such each node is limited to roughly 40% usage (memory/CPU) so that if a failure occurs there is minimal/0 service disruption. So we usually don't run highly loaded ESX hosts. So the 40% load numbers are the most interesting. Good article and lots to think about when deploying these systems.... Reply

    It would be nice to see some comparisons of blade systems in a similar vein to this article.

    Also you say that one system is better at say DBs whilst the the other is better at VMware, what about if you are running say a SQL database on a VMware platform? Which one would be best for that? How much does the application you are running in the VM affect the comparative performance figures you produce?

    is it really a question, anyone who has used both DRAC and ILO knows who wins. everyone at my current company has a tear come to their eyes when we remember ILO. over 4 years of supporting Proliants vs 1 year of Dell, i've had more hw problems with Dell. i've never before seen firmware brick a server, but they did it with a 2850, the answer, new motherboard. yay!

    This article should be renamed servers clash, finding alternatives to the Intel architecture. Yes it's slightly overpriced but it's extremely well put together. Only in the last few months has the 12c Opteron become an option. It's surprising you can build Dell 815's with four 71xx series and 10GB Nics for under a down payment on a house. This was not the case recently. It's a good article but it's clearly aimed to show that you can have great AMD alternatives for a bit more. The most interesting part of the article was how well AMD competed against a much more expensive 7500 series Xeon server. I enjoyed the article it was informative but the showdown style format was simply wrong for the content. Servers aren't commodity computers like desktops. They are aimed at a different type of user and I don't think that showdowns of vastly dissimilar hardware, from different price points and performance points, serve to inform IT Pros of anything they didn't already know. Spend more money for more power and spend it wisely...... Reply

    First off, I am glad that Anandtech is reviewing server systems, however I came away with more questions than answers after reading this article.

    First off, please test comparable systems. Your system specs were all over the board and there were way to many variables that can effect performance for any relevant data to be extracted from your tests.

    Second, HP, SGI and Dell will configure your system to spec... i.e. use 4GB dimms, drives, etcetera if you call them. However something that should be noted is that HP memory must be replaced with HP memory, something that is an important in making a purchase. HP, puts a "thermal sensor" on their dimms, that forces you to buy their overpriced memory (also the reason they will use 1GB dimms, unless you spec otherwise).

    Third, if this is going to be a comparison, between three manufactures offerings, compare those offerings. I came away feeling I should buy an IBM system (which wasn't even "reviewed")

    Lastly read the critiques others have written here, most a very valid.

    "First off, please test comparable systems."

    I can not agree with this. I have noticed too many times that sysadmins make the decision to go for a certain system too early, relying too much on past experiences. The choice for "quad socket rack" or "dual socket blade" should not be made because you are used to deal with these servers or because your partner pushes you in that direction.

    Just imagine that the quad Xeon 7500 would have done very well in the power department. Too many people would never consider them because they are not used to buy higher end systems. So they would populate a rack full of blades and lose the RAS, scalability and performance advantages.

    I am not saying that this gutfeeling is wrong most of the time, but I am advocating to keep an open mind. So the comparison of very different servers that can all do the job is definitely relevant.

    These VMWare benchmarks are worthless. I've been digesting this for a long long time and just had a light bulb moment when re-reading the review. You run highly loaded Hypervisors. NOONE does this in the Enterprise space. To make sure I'm not crazy I just called several other IT folks who work in large (read 500+ users minimum most in the thousands) and they all run at <50% load on each server to allow for failure. I personally run my servers at 60% load and prefer running more servers to distribute I/O than running less servers to consolidate heavily. With 3-5 servers I can really fine tune the storage subsystem to remove I/O bottlenecks from both the interface and disk subsystem. I understand that testing server hardware is difficult especially from a Virtualization standpoint, and I can't readily offer up better solutions to what you're trying to accomplish all I can say is that there need to be more hypervisors tested and some thought about workloads would go a long way. Testing a standard business on Windows setup would be informative. This would be an SQL Server, an Exchange Server, a Share Point server, two DC's, and 100 users. I think every server I've ever seen tested here is complete overkill for that workload but that's an extremely common workload. A remote environment such as TS or Citrix is another very common use of virtualization. The OS craps out long before hardware does when running many users concurrently in a remote environment. Spinning up many relatively weak VM's is perfect for this kind of workload. High performance Oracle environments are exactly what's being virtualized in the Server world yet it's one of your premier benchmarks. I've never seen a production high load Oracle environment that wasn't running on some kind of physical cluster with fancy storage. Just my 2 cents. Reply
