  • Hardware needed for 2000 users? [closed]

    - by Trcx
    I have school assignment that is fairly well defined, requiring us to come up with a plan for an environment serving dynamic web applications to 2000 users, and should be able to scale up to six thousand. I have done plenty of research as far as load balancing, redundancy, UPSs, etc, but am having a hard time figuring out how much hardware is actually needed in the way of physical servers, ram, processing power, etc. The assignment states that the server will have a lot of dynamic code, email, and a database are required, all utilizing the appropriate microsoft service (MS SQL, Exchange, IIS). I already plan on splitting them out on to separate servers, but can't even fathom the hardware requirements of something that large scale. Could someone with experience weight in on this, or point me two some good articles?

  • Do I need to match hardware on a Mac to my PC to get the same user experience?

    - by Darth
    I've been playing around with the thought of moving from a PC to a Mac. if you don't want to read this, skip to the "upgrade options" My current setup Most of my time I spent moving back and forth between Linux and Windows. During the last upgrade to Vista, I got myself pc with Core 2 Quad, 8GB of RAM and GeForce 9800GTX+. Currently I'm running dual boot between Ubuntu 10.04 and Windows Vista x64. Most of my work, around 80%, I can do on Ubuntu, which is mostly Ruby/Java programming. If that was all I needed, Ubuntu would be really great. However, I also do quite a lot of Photography and Design, which forces me to use Adobe software (not only Photoshop). I also work with Wacom Intuos4 tablet, which doesn't really have great support on Linux machines. I've tried virtualization both ways (Linux in Win and Win in Linux), but neither was anywhere near satisfying. These are those of many many reasons I want to move to OS X. Upgrade options This is how I see my upgrade options: Mac Mini - cheapest solution, but worst performance iMac - more expensive, better performing with second LCD for free Mac Pro - could match my current PC performance, currently outside of the price range When I compare the Mac hardware vs my current PC, it will be always worse, unless I decide to pump in a lot of money. The question that comes to my head, do I need to match my current PC hardware to get the same user experience with a Mac? If I look at it from the Vista point of view, 2GB RAM is as low as it gets, 4GB is usable ... and the 8GB runs very smoothly. PC HW != Mac HW? If I bought the Mac Mini for roughly the same price I paid for my PC (Core 2 Quad with 8GB RAM), I'd get Core 2 Duo with 4GB RAM. But I don't want to run Vista on it, so I can't compare the hardware directly. Say that I want to do the same things on the Mac Mini as I do on my PC, eg. open up 50 tabs in Google Chrome and start working with a large PSD in Photoshop (couple hundred MB), would running on Mac OS X compensate for the lower hardware performance? My point is, that if I'm about to upgrade, I wouldn't like to upgrade to hardware that runs a lot slower. Good analogy for this is Vista vs Ubuntu, where you can run Ubuntu smoothly on a low end laptop, but in Vista, you'd be happy to open a browser. Does the same principle apply to OS X?

  • Recommended motherboard with hardware raid for Linux

    - by luison
    Hi. We want to setup an internal office server for testing jobs (LAMP), email and samba. Only about 5-10 users. We are also considering starting to virtualize, initially by a base Ubuntu Server with Xen or VMWare Open Source server. Our current system runs with a Linux Raid which has worked great but it's always been complicated to recover the boot sector when one the drives fail and therefore I would prefer using now a hardware raid instead, but ideally with some kind of software monitoring. For this reason and considering we don't want to spend a fortune a I would appreciate any comments on the following options. Motherboard with RAID with linux support... which could you recommend. Motherboard + Hardware Raid card... Adaptec does not seem to have great Linux suppport. 3Ware seems to have a tc soft controller which we've used on a hosting company, but hard to find here in Spain. HP Proliant type basic server, which? Dell Small Servers... any good for Linux? Thanks in advance for any feedback.

  • VMWare Newbie - looking for hardware recommendations and help :) [closed]

    - by Dan
    I am looking for some hardware recommendations on an upcoming virtualization project. We are a small company (80 users - 25 in site 1, 55 in site 2) currently using Windows Server 2003 - no VM servers yet. Our AD is setup where site 1 is the root domain and site 2 is a subdomain/subnet - connected by T1 and VPN for failover. The current DC's also server as file servers, print servers, AntiVirus servers. Email is in the cloud. Additionally then in site 1 we have 3 additional member servers - one running IBM Websphere for a customer specific app, one running Infor PowerLink (no real heavy load) and another that we use for Virtual Studio apps and also runs DirSync for Exchange Online. No heavy workloads on any of these machines really. We also have an AS400 box that we run ERP/CRM software on that site 2 connects to over the WAN link. In site 2 we also have a SQL machine that runs on Win2K server. Database files are not large less than 5 GB. Light to Medium workload on this machine. File servers in each site store less than 500 GB data and probably won't grow to more than 1TB in the next 5 years. I am looking to go to VMWare in both sites and virtualize all servers. What recommendations do you have for server, storage hardware? Is it safe to virtualize all of your DC's? Any help or advice would be greatly appreciated. Thanks.

  • Hardware testing tool/suite

    - by Aviator
    Hi All, I just bought a new core i5 system (assembled) and started installing Windows 7. It was failing for many times and at some point got installed. After that, frequent crashes related to MEMORY. So checked the RAM using memtest86+ and found many errors.I got it replaced with the vendor and now if i install ANY OS, at some point in installation it either freezes completely with no response for hours, or restarts automatically. I tried installing Windows 7, Windows Vista and Ubuntu 9.10. I tested the new RAM again and found no problems in about 2 passes using memtest86+. I even updated the BIOS using bootable USB and even the problem persists. I am really not sure which hardware is causing trouble. I dont have any OS inside it, so i have to check using bootable CDs DVDs and USB only. Please advice on how to proceed. Are there any suites/ separate tools for checking integrity of each hardware parts and troubleshoot it? I wanted to confirm which part is problematic before going for replacement. Thanks a lot! This is the config: Core i5, MSI P55-GD65, GSKill 2x2GB, Seagate 500GB 7200rpm, CM Extreme 600W PSU, Saphhire Radeon 5770 1GB, LG DVD Writer

  • Les développeurs amateurs se mettent aux hacking avec la prolifération des kits de piratage « tout-e

    Mise à jour du 29/04/10 Les développeurs amateurs se mettent aux hacking Avec la prolifération des kits de piratage « tout en un », mais ils restent très professionnels Les kits de hacking « do-it-yourself » (en vf « faîtes le vous même ») se propageraient à grande vitesse. Ces solutions « tout en un » facilitent en effet la création et l'utilisation de malwares (un constat également fait par Microsoft dans son rapport semestriel de sécurité - lire ci-avant). Leurs prix relativement bas aura fait le reste pour leur démocratisation auprès de tous les développeurs malveillants, y compris les moins doués. Dans son étude, M8...

  • Mythbusters- Programming/hacking myths [closed]

    - by stephen776
    Hey guys. I am a big fan of the Discovery show Mythbusters, as Im sure some of you are as well. I have always wanted them to do an episode on programming/hacking. They get a lot of their show ideas from fans so I though we could compile a list of possible myths to bust. Lets hear your ideas! (sorry if this is not appropriate, close if necessary) Edit: I am not necessarily looking for subjective "This is what I want to see" answers. I am talking more along the lines of interesting computer/programming/hacking stories that would appeal to a general audience. I do not expect them to do a show on "Whats faster i++ or i + 1".

  • Hardware Emulator / Simulator for Winforms .Net Application

    - by Suneet
    I have a WinForms .Net HMI software which talks to hardware over USB. I check for communication with the hardware at Load time and if communication is active then run it (The hardware manufacturer has provided a communication library to talk over USB). I want to build an emulator for cases when communication with hardware is not possible (not connected) and want the software to run in simulated mode by providing dummy values for different states of hardware. Has anyone implemented something similar? Any pointers will be helpful. Are there any design patterns to handle such implementations. TIA

  • Getting a hardware profile from Fedora 12 after installation

    - by Chris T
    I've installed Fedora 12 on a computer I found in the trash (Bulk garbage day!) and I'm trying to figure out what's under the hood (seems like a stock dell but I'd like to know the details). Is there a way to get a hardware profile on Fedora after it's already installed on the harddrive? I saw an option at install but I skipped over it.

  • best way to go about cost-benefit analysis on hardware

    - by Michael
    I'm looking to build a low-end computational server (my jargon in this field is especially limited so if someone can state that better please change that to meet jargon). I'm basically running computational fluid dynamics programs, large matrix computations and bioinformatics code. What would be the best way to approach cost/benefit analysis on what to put in the system? Perhaps even more general: How does one approach cost/benefit analysis on hardware theoretically (doing the analysis before building the machine)?

  • Toolbox for Computer Hardware

    - by Chuy77
    I have a lot of computer hardware (hard drives, cables, etc.) and I need a better way to organize. Could anyone recommend a toolbox intended for this sort of thing, or some other good method for storage? I have a two drawer wide file that I currently use, with large plastic bags. It works okay, but I need a better system. Thanks for any advice.

  • Workstation hardware at does your company buy developers?

    - by Bosh
    I'm curious to know what workstation hardware companies are devoting to you, as a developer -- and how much they're spending. I'd consider this thread a big success if I could shed some light on these questions: Do engineers at big companies use substantially different hardware than engineers at start-ups companies? Does a fresh developer recruit at Google get substantially different hardware from someone in the same position at Microsoft or Yahoo!? Do programmers in more senior positions have more powerful hardware on their desks? Does anyone think faster hardware makes more efficient engineers?

  • Feeding a Dog Remotely - hardware?

    - by RobDude
    I'm looking for a way to, remotely, activate some sort of treat dispenser. I'm not a hardware guy, and I'm sure that conceptually, this is very easy. But I don't know how to begin. I haven't found any products designed to do exactly this. Perhaps some sort of beginning robotics kit could do it?

  • HP Proliant G7 hardware RAID configuration automation with ribcl

    - by karthik
    I have been trying to automate hardware RAID configuration of HP proliant machines before OS installation (So I can not use hpacucli) ssh into iLO3 doesn't have option for RAID configuration I use ribcl but there is no command for RAID config, however I see this under the command GET_EMBEDDED_HEALTH. <STORAGE> <CONTROLLER> <LABEL VALUE="Controller on System Board"/> <STATUS VALUE="OK"/> <CONTROLLER_STATUS VALUE="OK"/> <SERIAL_NUMBER VALUE="50014380215F0070"/> <MODEL VALUE="HP Smart Array P420i Controller"/> <FW_VERSION VALUE="3.41"/> <DRIVE_ENCLOSURE> <LABEL VALUE="Port 1I Box 1"/> <STATUS VALUE="OK"/> <DRIVE_BAY VALUE="04"/> </DRIVE_ENCLOSURE> <DRIVE_ENCLOSURE> <LABEL VALUE="Port 2I Box 0"/> <STATUS VALUE="OK"/> <DRIVE_BAY VALUE="01"/> </DRIVE_ENCLOSURE> <LOGICAL_DRIVE> <LABEL VALUE="01"/> <STATUS VALUE="OK"/> <CAPACITY VALUE="68 GB"/> <FAULT_TOLERANCE VALUE="RAID 0"/> <PHYSICAL_DRIVE> <LABEL VALUE="Port 1I Box 1 Bay 3"/> <STATUS VALUE="OK"/> <SERIAL_NUMBER VALUE="6TA0N3SZ0000B231CYDT"/> <MODEL VALUE="EH0072FAWJA"/> <CAPACITY VALUE="68 GB"/> <LOCATION VALUE="Port 1I Box 1 Bay 3"/> <FW_VERSION VALUE="HPDH"/> <DRIVE_CONFIGURATION VALUE="Configured"/> </PHYSICAL_DRIVE> </LOGICAL_DRIVE> </CONTROLLER> </STORAGE> My question is, is there a way I modify/create this xml piece (say I have 2 Logical drive with one spare) and reboot the server it takes effect ? If this approach is not correct are there any other ways to automate hardware raid config ?
