When selecting a CPU architecture for a web-server, you do need to know what you're doing with the server itself. Only you can tell if what you're doing can take advantage of multiple cores, or if it is solidly single-threaded. PassMark's PerformanceTest product test distils CPU performance down to a single number, yet what you're doing with your web-server ...

From what I've seen, there are three things to be aware of for i-series processors vs Xeon series processors: Xeon processors can typically be used in multi-cpu motherboards; i-Series processors cannot (just like the sales guy told you). This is by far the largest difference between between the processors themselves. Certainly a good i7 processor has the ...

Should be very little difference in performance between two dual core CPUs and a single quad core CPU, if you are using current Intel Xeons. However, you might expect to see slightly better performance from the quad-core CPU if it is a "true" Quad core design, ala the new AMD Opterons or the new Xeon W5xxx (aka the Core i7 / Nehalem) series. ...

i7z is a good tool for monitoring Intel Turbo Boost for Intel CPUs that support it (i7 and later) on Linux. If it is working, you will see the current frequency change as you add load to the CPUs, due to the multiplier increasing dynamically under load. Try BurnP6 for this. Basic description (pdf) of power states: C0 - active state. While in C0, ...

Faster DDR memory should always work in a system that only supports slower clocked memory - it's part of the spec. However you do have to stick with the stated type (ie DDR3\DDR2\DDR). I would generally advise someone to buy the correctly rated memory but if all the parts are built to spec then there should be no issue using faster rated memory in an ...

We've just ordered two Dell M910 blades with 4x Xeon X7560. That's Octo-Core 2.26Ghz. They cost close to 6 figures each and are the fastest Intel processors available on the market today. There is SO MUCH more to a processor than just clock speed. If I took just four of those 2.26Ghz cores and put them against a quad-socket P4 generation 2.8Ghz server I ...

I think round here you will get many people suggesting an extra drive and RAID 10 rather than RAID 5 as the write performance is much higher under load. I personally would say if the drives aren't going to see high IOPS (especially random IOPS) then RAID 5 would do. However I've noticed you have chosen WD Green SATA drives - I would consider these a very ...

The RAID on that motherboard is not real hardware RAID, it's "fakeraid" that depends on drivers in the operating system. ESXi doesn't support fakeraid, because it's aimed at enterprise environments (which use real hardware RAID for better performance), not consumer PCs (which use fakeraid because it's cheap). ESXi should recognize drives connected to that ...

Please help Dude, a reality check. Machines BREAK DOWN. When they break down, they get fixed or replaces. YOu must be VERY new to life if you never needed for example a car mechanic. Things DO break down, there is nothing special about it. Now, what to do? SIMPLE. Depending on when the server was purchased, do one of the following: contact shop for ...

Let me get this straight. You upgraded the client based on a hunch and a single benchmark? That's a mistake. Benchmarks are entirely artificial and do not reflect how real world programs will perform. I will say that they do however provide an indication of potential performance. Firstly, there is a lot more to getting apps to perform well on multiple ...

Looks like VMware KB 1034926 specifically covers this. some Westmere micro-architecture processors that have AES/PCLMULQDQ features disabled are not permitted into Intel Westmere (Xeon 32nm Core i7) EVC clusters. If these features cannot be enabled in the BIOS, the host will only be admitted to the Intel Nehalem Generation mode or below. Hopefully the ...

Make sure your client understands what they are asking for. It's very easy to find systems that match the specs you have given above, but almost certainly will be something they are quite unhappy with. Is your client aware that when Intel went to the Core architecture they increased the amount of work that can be done per clock, and reduced the clocks? I ...

What's your definition of "better"? Will it be faster? Probably. Will it require less power? Yes. Will it be more reliable? Maybe not. Even if a single SSD proves to be more reliable than a single standard hard drive (which is up for debate), your data is still not protected from a single-drive failure like it would be in a RAID1 scenario. Additionally, ...

In my experience using a 32 and 64 bit variants of FreeBSD on the same hardware, I have seen a measurable (but not huge) benefit to running 64 bit. 64 bit has been around long enough that active projects don't have issues. The one area this is not necessarily true is for compiled commercial apps (doesn't sound like an issue for your workload). If you were ...

OK, the previous answers have talked about why it's a bad idea to use fakeraid, why VMware doesn't support it, and to some extent why using a desktop motherboard isn't such a good idea. If you're really set on using this board as the base for a VMware server, this is what you do: Go to eBay. Search for DELL PERC 6/i. Buy one, preferably one that includes ...

533MHz is not possible on this gear. This is a problem with the interpretation of the CPU-Z results. Multiply that frequency by the data rate (2x or DDR), giving you 1066MHz. But 1066MHz isn't what you were expecting either!! For the rest of the setup, there are a few factors to consider. The DIMM population guidelines for the server are below. You have 18 ...

Sparc IV processors enjoy a supercomputer-like memory bus that has only been approached or equaled by the introduction of Core i7. As a result the are good at churning through large quantities of data (think database, large analysis) at a consistant rate. Actual Dhrystone benchmarks usually trail Intel. UltraSPARC-T1 processors plow through parallel ...

There is compatibility going beyond VMWare's HCL - a "whitebox HCL" has been assembled by the community listing a lot of components which ESX(i) has been found to work with. It also has something to say about software RAID controllers: this list includes a number of SATA controllers that provide RAID functionily via a software component in the ...

Intel vPro technology is a platform that requires specific ingredients - you need to have a vPro-capable processor and a vPro-capable motherboard. You can look up processors and boards on http://ark.intel.com and that site will tell you exactly which functionality is available on each component. One thing that I've learned about that site is that vPro ...

You should be able to ignore this - this is simply how CentOS labels its 64-bit packages, which work on both AMD and Intel processors that are 64-bit capable. Any quirky behavior would not be caused by this - there are no AMD or Intel specific packages in any Linux distribution, as far as I'm aware; just 32 or 64 bit

I wrestled with the same problem. My solution was to lock down the control panel and disable the Intel program. I disabled the Intel program with a startup script that ran a registry update: startup.bat: reg delete HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run /v IgfxTray /f

That processor only support OpenCL 1.1, and has 12 execution units. Compare that with the AMD A10-5800K with OpenCL 1.2 and 384 execution units. Intel's graphics are notoriously unimpressive. It's highly unlikely any of your software will have the drivers or OpenCL capabilities to use the graphics "card" in that processor anyway. It's very uncommon to see ...

From this excellent Intel blog post which is at the top of the google results for vt-d: VT-d, at the time of this writing, includes four key capabilities I/O device assignment. This feature allows an administrator to assign I/O devices to VMs in any desired configuration. DMA remapping. Supports address translations for device DMA data ...

In general, are processor fans a standard size, and will most fans fit most motherboards? Very rarely are there CPU fans in a server. In most cases, there is simply a heatsink and the airflow is handled by intake fans behind the drive cage (front of the server) and sometimes exhaust fans right in front of the PSU units. Of course, this can differ from ...

Since there is a virtualization layer between your server OS and the hardware with EC2, there's not even a guarantee that all 8 threads from your vCPUs are executing on the same physical CPU. Trying to measure things like cache hits or patters from inside the guest are an exercise in futility. You don't have visibility into the actual hardware. A vCPU ...

If the total amount of data on the array is less then the capacity of a single drive, you can remove one drive from the array and format it as a normal drive, then copy over the data and after that, dismantle the rest of the array. If the amount is larger than a single drive, it's impossible. It's also impossible to step down from a RAID without copying the ...

You will see 6 x 2.4GHz (14.4GHz). The Intel HyperThreaded CPU cores do not count towards the CPU resources. Here's an example with a single quad-core Intel 2.26GHz CPU: And the socket information:

Since Intel launched their Nehalem (55xx-series) all =>2 socket Xeons are NUMA by default, including the E5-2630's. Some BIOS/UEFI's allow this to be disabled but the option is usually hidden away to discourage it. You don't mention which hypervisor you're using but certainly any recent server-class products from VMWare, MS and Xen/KVM are NUMA-aware and ...

Yes, the DL360p is NUMA-capable. It's the system default. Assuming VMWare, the handling of VMs on NUMA architecture has changed slightly as the product evolved. See this excellent site for a good breakdown. With the current edition of VMWare (5.x), you will end up with NUMA nodes inside the guest if you configure more vCPUs than exist on on physical NUMA ...
