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.

    So, the "product differentiators" from HP are because they primarily sell through partner channels. This is the model IBM used for years; and if you buy your ProLiants through an HP partner and not a mere reseller, they will know the product line and can configure the hardware however you want. HP does very well at making their servers extremely modular, but you do have to know how/where to find the part numbers. Often this information is not widely distributed outside of HP's partner sales trainings (which are very good.)

    If you're used to the Dell model of sales, it doesn't make much sense. But because Dell sells directly, their policies for channel partners are stupid (the wholesale price for a channel partner is often higher than the retail price for a direct customer.) But because partners have more pricing and configuration flexibility from HP, the partner can often beat Dell's direct price with HP hardware (which IMO is higher quality than Dell anyway.) Dell doesn't want their partners to compete with their direct sales and HP doesn't want to jeopardize their partner relationships by pushing direct sales too hard.

    There are pros and cons to each approach, and it all depends on how you handle your IT. If most of it is in-house, but you're not quite big enough to have an internal buyer who would take in the HP sales training, Dell makes a lot of sense because, well, it's easy to understand and most HP partners make their money off implementation services, not hardware sales. Dell is willing to work with you a little more. But if you look at companies where IT is not a core competency (regional insurance companies, banks, etc) a lot of them use consultants to do IT projects/maintenance and HP is making an absolute killing in this market.

    insightful and enlightening comment. Still, there is a point where extremely modular increases the complexity and price too much. The result is a slightly higher price (which is still acceptable, but sometimes also small configuration mistakes which cause extra delays. The result is significant higher cost. And this happens regularly as even trained people make mistakes. So my first impression is that HP should lower the complexity a bit. Reply

    True; but without a "direct sales" option they have no way to offer flexible configurations without having a different part number for every possible configuration. Most HP partners will simply use a sales quote tool to build server configurations (in fact; this is exactly what Dell does if you order through their sales reps, which is how you get the best prices.) Again though; HP partners are unlikely to give you a sweetheart deal unless you're buying implementation services from them as well. They make 5-10% on the hardware and 80-150% on the labor,

    But I'll tell you now that HP was consistently able to beat Dell on price through channels over the last 5 years. IMO this is because Dell has the same sort of parts system internally; HP cuts costs by not bothering to make sense of it all and just pushing it off onto their resellers. They're pretty much not interested in selling direct to consumers because it's really just a small part of their business.

    What's killed Dell's profits over the last few years has been that the economic troubles have pushed small/midsize companies to outsource their IT. The companies they outsource to are probably HP partners. Thus, when these companies need hardware, it's likely to be HP (used to be IBM as well; but IBM's support is pathetic and their prices are in the stratosphere.) Channel resellers are also used to dealing with complicated product lists (last I checked Symantec's product book had something like 25,000 individual SKUs) so it's probably not going to change. If anything, it's likely to get worse. For all the consumerization in IT, the enterprise side is only getting more complicated. I wouldn't try to spec a server from HP without at least being familiar with their product line and the options it offers.

    Being a bit weird we buy Dell PCs (and a sprinkling of Macs) and HP servers.

    The Dell PCs are cheap and do the job, initial sales calls are good and they will bust a gut on price but beyond that Dell are pretty much hopeless at support in the UK, with our sales manager changing 3 or 4 times a year and never refering any support calls to some else in the team w have never heard of before.

    Our HP partner, however, is much more stable and they are generally knowledgeable and help configure servers accordingly though for the most part they are actually straight forward until some nutty developer wants 16 disks locally in an 580 g5. And we have a single point of contact for everything.

    You pays your money and you takes your choice.

    Did mention the next day or two (HP) versus 1 to 2 weeks (Dell) delivery options?

    The draw full of 2 GB DDR3 RAM I have from our HP blades is very irritating, I wish HP would supply with out any RAM installed, it is such a waste.

    Nice article but HP either sells DL380 (Intel) or DL385 (AMD) servers. Please correct all the DL387 references. Reply
  • JohanAnandtech - Thursday, September 09, 2010 - link

    Yes, fixed that one. I always get in trouble with these number codes. Reply

    Great review, I love it when different platforms are compared to each other. Also happy to see AMD hold their own to the much lauded 7500 series Xeons in a market that I feel AMD is better suited for (VM Servers)

    However, its possible I missed it, but was the price of the SGI system listed anywhere? It would have been nice to see the price of each system as configured side by side.

    Pictures on Page 5-6 look delicious.

    "Comparing the dual with the quad Opteron 6174 power numbers, we notice a relatively high increase in power: 244 Watt. So for each Opteron that we add, we measure 122 W at the wall. This 122 W includes a few Watts of PSU losses, VRM and DIMM wiring losses. So the real power consumed by the processor is probably somewhere between 100 and 110W. Which is much closer to the TDP (115W) than the ACP (80W) of this CPU."

    when the power draw test was done between 2 socket and 4 socket dell 815 did you remain with the same amount of dimms? so you divided the 2 socket amount in the 4 socket?

    On the power draw calculation don't forget that you also have an additional SR5690 to account for which is 18W TDP, electronics etc, so I don't think it will be operating close to TDP but neither to ACP :)

    btw a lot of mistakes with the HP 387G7 which should be 380G7

    This is a strong article. Very helpful and most of us basically need to decide which customer we are and what matches our apps and usage requirements. Reply
