  2. Re:I'd go for the Netra on 1U Apache Servers - Sun or Intel? · · Score: 2

    The UltraSparc throughput is the answer to why the Sparc outperforms under load. The UltraSparc can handle nearly x6 the throughput of the Pentium III. The Sparc will be a much more stable under pressure than the Pentium, which will start to cave under a massive number of context switches. However, the Sparc's slower horsepower will start to smell if you are doing lots of SSL.

  3. Breakdown Sun/Dell+VA on 1U Apache Servers - Sun or Intel? · · Score: 4

    I. Operating Systems. Well (here comes the flamebait), there are pluses and minus to Solaris vs. BSD or Linux. In these simple systems performance wont vary much between the OS's. However, Solaris is the more reliable OS (better NFS implementation, etc). As far as the OS goes, I'd have to say Solaris, except for the sun compiler which is a complete piece of sh*t and a pain in the ass if you are doing some custom C stuff. Ultimately, if it were me, I'd prefer to work with Solaris here, especially if your running a Java middle-teir (servlets).

    II. CPU. What matters here is the usage, and my first question would be are you going to be doing SSL. If so, are you using an accelerator in front of the cluster? If you are using an accelerator, I would lean towards the UltraSPARC IIe. The SPARC wont perform SSL as fast as the Pentiums and the Pentiums frankly have better caching layouts than these lowend SPARCs. Without a SSL accelerator appliance, the Pentiums will considerably outperform almost 2:1 over the Ultra.

    III. Maintenance. This is the tough one. If you have to replace one of the Sun ethernet cards or hard drives get out your checkbook (we are talking Sun here). The Intel configs will be cheaper to maintain.

    IV. Hard Drives. Drives for these guys really are for caching and virtual memory since you are going with a cluster. The reality is that IDE is perfect for this use, since your net connections are going to be the primary choke points. And the Sun IDE drive is faster than the VA box drive. The Dell is SCSI which is probably not economical for most purposes.

    V. Networking. The key here is that the Sun box only has room for one network card. So, if you need 2 cards, the answer is pretty simple. Both the dell and VA box have room for two. Also, if you want something other than base 10/100 ethernet, you aint gettin it with the Sun box.

    VI. Other Drives. The Sun box doesnt have a CD drive, (which is fine considering its a cluster) or a floppy drive, and the others do. This is a nice cost saving measure if your clustering.

    VII. Memory. Sun's memory bug is no longer around, so memory is pretty much even ground here. All of these guys come with 128 Megs on the lowend, which is probably too little depending on your purpose.

    VIII. Service/Support. Dell has very good service and support. Sun has bad support, but they honor warranties. I've never used VA, but heck they own /. (hmmm).

    Summary. I'm sure I'm missing stuff, but this is a start. If you are just serving up flat files, I dont think I'd go with the sun, but I dont think I'd go with either of your other choices. I'd probably go with the VA 1120, or the low-end dell. (or look at another vendor like pengiun, etc). If you are running app servers, then I'd fork based on what the medium is. Mod perl stuff probably lends better for non-solaris environments (I could be fudding now), but Java definetly runs better on Solaris (I wonder why?). For C/C++ stuff, the toss up is with your compiler choice. If you are using other open source stuff, you probably dont want to be using gcc on Solaris (flamebait alert!) for optimal performance, but you'll have a nightmare of compatibility issues if you use the sun compiler. If you're using third-party binaries, who cares.

    New Physics Theory Highlights:

    Due to the fact that the size of the anomalous acceleration is of order cH, whereH is the Hubble
    constant (see Eq. (56)), the Pioneer results have stimulated a number of new physics suggestions.
    For example, Rosales and S anchez-Gomez [136] propose that aP is due to a local curvature in
    light geodesics in the expanding spacetime universe. They argue that the Pioneer eect represents
    a new cosmological Foucault experiment, since the solar system coordinates are not true inertial
    coordinates with respect to the expansion of the universe. Therefore, the Pioneers are mimicking
    the role that the rotating Earth plays in Foucault's experiment. Therefore, in this picture the
    eect is not a \true physical eect" and a coordinate transformation to the co-moving cosmological
    coordinate frame would entirely remove the Pioneer eect.
    From a similar viewpoint, Guruprasad [137] nds accommodation for the constant term while
    trying to explain the annual term as a tidal eect on the physical structure of the spacecraft
    itself. In particular, he suggests that the deformations of the physical structure of the spacecraft
    (due to external factors such as the eective solar and galactic tidal forces) combined with the
    spin of the spacecraft are directly responsible for the detected annual anomaly. Moreover, he
    proposes a hypothesis of the planetary Hubble's ow and suggests that Pioneer's anomaly does
    not contradict the existing planetary data, but supports his new theory of relativistically elastic
    space-time.
    stvang [138] further exploits the fact that the gravitational eld of the solar system is
    not static with respect to the cosmic expansion. He does note, however, that in order to be
    acceptable, any non-standard explanation of the eect should follow from a general theoretical
    framework. Even so, stvang still presents quite a radical model. This model advocates the use
    of an expanded PPN-framework that includes a direct eect on local scales due to the cosmic
    space-time expansion.
    Belayev [139] considers a Kaluza-Klein model in 5 dimensions with a time-varying scale factor
    for the compactied fth dimension. His comprehensive analysis led to the conclusion that a
    variation of the physical constants on a cosmic time scale is responsible for the appearance of the
    anomalous acceleration observed in the Pioneer 10/11 tracking data.
    Modanese [140] considers the eect of a scale-dependent cosmological term in the gravitational
    action. It turns out that, even in the case of a static spherically-symmetric source, the external
    solution of his modied gravitational eld equations contains a non-Schwartzschild-like component
    that depends on the size of the test particles. He argues that this additional term may be relevant
    to the observed anomaly.
    A proposal to modify the theory of gravity in order to provide an explanation of the Pioneer
    anomaly has also appeared. Capozzielo et al. [141] discuss the possibility of determining the
    stability and characteristic geometrical and kinematical properties of galaxies strictly based on a
    minimal action whose value is on the order of the Plank constant.

After those incidents, the reports concluded that the individuals in the cases didn't encrypt the information because of the expense and difficultly involved with the current day encryption technologies. The findings advised that the commerical restraints on encryption be lifted in order to more cheaply secure government data.
