Taking a Look Inside

As with most hardware at AnandTech, we needed to take a look inside to fully determine the capabilities of our V40z. Upon entry of the system, we are greeted with a diagram of the V40z quick reference on the back of the removable panel.

With the exception of the removable top panel, the entire Sun Fire V40z can be disassembled completely without any tools. Locking mechanisms in strategic places assure that power supplies, bezels and hard drives stay in place when they should, but at the same time, to remove a critical component – even during operation – seems relatively easy. Without the main bank of internal fans, we can see the rear processors under their giant 4” copper heat sinks.

We actually stumbled across a block diagram of the motherboard and daughterboard outlining most of the components that make up the Sun Fire V40z. We intend to go in detail about each of the components and their purpose.

Because of the 3U design of the Sun Fire, a motherboard and daughterboard design was needed to allow maintenance of the second set of Opteron processors. The processors on the daughterboard are referred to as the “forward” CPUs because they pull out of the front of our V40z. The “rear” processors are technically the CPU0 and CPU1 to our operating system and are located on the mainboard.

    Did anybody else find it confusing that the reviewed system had CG-stepping Opteron 850s and Kris brought up E4-stepping Opteron 852s on multiple occasions? What CPUs were actually in the system? Reply

    Last page, ..

    "Sun has a speed **daemon** on their hands, ..."

    Freudian slip, hehe? Nice read nonetheless.

    MrEMan: Mediaplex is just an advertising server. Some advertisers (like NewEgg) host their banners on Mediaplex so they don't destroy their bandwidth. Sometimes when an ad campaign is hitting too many impressions the Mediaplex tag will revert to a 2x2 or a 1x1 pixel so that they don't harm their click through rates. It has nothing to do with spyware or malware or adware.

    What is with the 1/16" x 1/16" graphic (1280x1024 resolution on a 19" CRT monitor) for adfarm.mediaplex.com ?

    Is it there with your permission or did someone hack your site?

    If it is there with your permission, I must say I am surprised that you would put such stealth adware garbage links on your site.

    I'd love to see some benchmarks with Solaris instead of or vs. Linux for reference too. Nice read though as usual. Reply

    "particularly considering the fact that the V40z does not utilize any active cooling directly on their CPU heat sinks"

    whoa, proper spelling of heat sink!

    now i'm going to harp on the fact that blowing air across a radiator with a fan is not active cooling. air conditioning is active cooling, turning on the ceiling fan is not.


    nice read

    I wish I could see a comparison of this and that Quad Opteron HP server. I have the HP one budgeted for this year already... (we're also a Sun shop).

    I didn't see an option for 15k RPM drives though. I could put in like 5-146GB@15k RPM in the HP which was one reason I was leaning towards it.

    Looking forward for a comparsion with HP DL585 / DL 385, both are also Monsters! Reply

    Googer, that's true, Sun basically just rebadges Newisys servers, the same is true of the V20Z, in fact IIRC you can actually find some Newisys marks left on the servers :)

    Anyway, Kris, any chance of a couple of benchmarks with a 2.6 based distro?
    2.6 has, among other things, good NUMA support, something that would be nice to have when running a 4-way Opteron ;)

    Another 250/850 typo on page 3: "Below, you can see one of the Opteron 250s is exposed from under the copper heat sink on the daughterboard."
