Rochester Memory Hardware Error Research Project Overview Our research focuses on the characteristics of memory hardware errors and their implications on software systems. A plethora of research works can be found on memory fault tolerance. Often times researchers use accelerated tests in their controlled environments to collect data. We have taken a different approach to conduct field tests that monitor computers in real time and record the actual errors happening on them. Memory errors can be categorized as soft errors and hard errors. Soft errors are also known as transient errors, which refer to those errors that are caused by environmental factors only and would not have lasting effects on memory hardware. Hard errors (or permanent errors) include those that are due to real hardware defects. We discovered that in each of our measured environments, the soft error rates are orders of magnitude lower than previously reported on a per Mbit basis. In the server farm at Ask.com , we have found quite a few hard errors. We made some error rate/pattern analysis in our USENIX'07 and HotDep'07 papers. Our recent

For information about developing device drivers for a specific type of device, see Windows CE Drivers RAM For execution of software on a networked media device (NMD), your hardware must have 32-bit wide SDRAM with a minimum frequency of 100 MHz. To provide a better user experience with smoother audio and video playback, use more SDRAM to buffer more audio and video data. Additionally, having more SDRAM allows more applications to execute in parallel on the target device. The following table shows the required and recommended amounts of SDRAM. RAM requirement level NMD DVR Required 32 MB 32 MB Recommended 64 MB 128 MB ROM or flash ROM or flash stores the operating system (OS) and the application software. It can be 16 or 32-bits wide. You can use NAND-based or NOR-based flash. You can use other media, such as a hard disk drive, to store the run-time image. Keep in mind that due to moving parts, hard disk drives are less reliable than solid-state media. You must reserve 2 MB of ROM or flash for the boot loader. In the boot loader, you must implement a master reset method for all ROM or flash memory, which includes the file system and the registry.

Home About Free eBook Archives ... Contact How To Diagnose Memory (Hardware) Issues on DELL Servers by Ramesh Natarajan on June 4, 2008 This Diagnostics tools can be used on DELL PowerEdge servers and PowerVault. Following items are covered in this post: Download Diagnostics utility from Dell support site. Create bootable CD Execute the memory test Graphics based diagnostics 1. Download Diagnostics Utility from Dell Support Site Go to support.dell.com 2. Create a bootable CD Run the EW5091A1.EXE and follow the directions to create a bootable Dell Diagnostics CD as shown below (1) Welcome Screen: This displays all the PowerEdge and PowerVault models that are supported by this particular diagnostics tool. (2) Extract Files : Specify the location where you would like to extract the files. (3) Choose Bootable Image Media (4) Create Bootable CD: Specify whether you want to directly burn to CD (or) create an ISO image. I burned it to a CD. 3. Execute the memory test (1) Dell Diagnostics Menu: Once you burn a bootable Dell Diagnostics CD, insert it to the server where you want to perform the memory test and reboot. This will display the Diagnostics Menu with the following four options. (2) MpMemory diagnostics : Select Option 1 to perform the memory test. This will perform various memory test and display a summary of the test. In the example shown below, all the test were conducted successfully and MpMemory did not find any issues with the memory on the DELL Server. If any of the memory test failed, please work with DELL support to get the memory replaced.

Virtual Memory Hardware Page last updated Characteristics of Virtual Memory Memory references within a process are logical addresses dynamically translated to physical addresses at runtime. A process is broken into pages or segments Not all the pages or segments need to be in memory at the same time More processes may be maintained in memory than normally permitted if entire address spaces of processes had to reside in memory Processes can be larger than actual physical memory Resident set - the pages or segments of a process that are in real memory. Real memory - the actual physical memory of the hardware Virtual memory - the perceived memory space for a process. Locality Locality is the reason VM works so well. The nature of program execution is that most often a memory reference is one that has recently been accessed or is one that is very close to a recently accessed location. sequential execution of code (nearby code) loops (nearby and already accessed code) repeated calls to subroutines sequential processing of data structures Figure 8.1 is a classic mapping of paging behavior, demonstrating the existence of locality.
