• Can I use a Windows Server 2003 Domain Controller but my home router for DNS?

  - by NetworkingWannabie

  Hi All Probably easiest to start with a description of my current setup, which works (oh, and this is a home setup not an office or anything): I have an ADSL modem with a static IP address (192.168.128.1), and its DHCP capability is disabled. I have a permanently powered up Windows Server 2003 machine with a fixed IP (192.168.128.2) which provides my domain controller, dhcp, and dns. The default gateway for everything is my ADSL modem everything is setup to use the WS2003 machine as the primary DNS with the ADSL modem as Secondary DNS just in case the server goes down (everything includes the server itself). Lastly, just in case it's relevant, I have my DHCP leases set to infinite (or whatever the right term is). Everything is pretty hunky dory. Except, that is, for the fact that my server is ALWAYS on, and it isn't always used, so I'm burning juice that I don't need to - my server burns around 120W which isn't immense but isn't irrelevant either, so I'd like to put it into a stand-by state when it isn't being used (the more standby the better) and then get the clients to wake it up. Am I correct in assuming that this won't work at the moment - A given client would need an IP address to wake the machine up, and it needs to machine to be awake to get an IP - catch 22? Assuming I'm correct, can I move to using my router (which is always on) for DHCP? What impact will this have on DC and DNS? Alternatively, does anyone have a better way for me to achieve this? Can I get the server to wake up when it sees clients look for a DHCP server, etc? Wow, that came out longer than expected! Thanks for your help.

• What's the best way to completely remove everything from a computer, without re-installing?

  - by Connor W

  I have a friend who wants to sell their computer, but obviously all personal information and software that it is on it needs to be removed before doing so. Usually I would format and reinstall it, but I cannot easily get hold of the required XP DVDs and I'm not 100% sure the serial number is stuck on the case as usual so getting hold of it will probably require more effort than I'm prepared to spend. So, what's the best and quickest way to remove and uninstall everything from the PC without reinstalling it? Thanks. EDITS: I'm looking to remove things like Internet History and all installed programs, too. I know how to remove the history and each individual program, but that could take hours. The machine is not branded and therefore there is no website I can go to download recovery software. There is no recovery partition on the computer and I'm not aware of any recovery DVDs for it either. I can only assume it was installed from a retail copy, and therefore there is no way to recover it to factory settings. It needs to have XP installed, not any distribution of Linux. Like most average people, the person getting the computer will not understand what to do with a computer that doesn't have Windows installed, and software like Office does not work on Linux either. Buying another licence is not really an option either. She has just brought a laptop to replace the computer, so buying another licence for a computer that she's getting rid of doesn't really make sense. Thanks for all the help so far!

• Windows 7 mapped drive kicking off OS X users

  - by Collin White

  I've mapped a network drive on my Windows 7 PC at my office. The windows machine has a few TB of storage that is being accessed by my development team (all running mac os 10.7). The share seems to work fine for a little while but will timeout and kick the mac users off and sometimes disallows a connection on the next attempt. Restarting the windows machine fixes the problem. I've tried this tutorial as well as setting the maximum session length in the Local Security Policy section to 99999 (I discovered 0 did not mean unlimited, only a 'reasonable ammount of time') anyway, the setting is now for ~208 days which is sufficient (see attached). I'm having trouble debugging this in general so if anyone has some pointers I'm all ears. This is a intermittent issue which in my opinion are the hardest kinds to debug. If anyone knows of how I might monitor connections from the PC that would also be pretty cool. Previously the files were hosted on a mac mini and everything was working just fine (the mini just didn't have the ability for the storage capacity we needed) so I believe it is some windows setting that is kicking users off. Anyway, thanks for reading.

• How to publish internal data to the internet - as simple as possible

  - by mlarsen

  I Asked this at Staock Overflow, but I would like your oppinion too as it has as much to do with administration as it does with coding. We have a .net 2-tier application where a desktop program is talking to a database. We support MS SQL Server 2000, 2005, 2008 and Oracle 9, 10 and 11. The application is sold, not as shrink-wrap, but pretty close. It is quite important for us that the installation and configuration is as easy as possible as installation instructions are usually supplied in written form to the customers internal IT-department. Our application is usually not seen as mission critical for the IT-department, so we need to keep their work down to a minimum. Now we are starting to get wishes for a web application build on top of the same data. The web application will be hosted by us and delivered as a SaaS application. Now the challenge is how to move data back and forth between the web application and the customers internal database. as I see it we have some requirements: We must be ready to handle the situation where the customers database is not accessible from the DMZ. I guess the easiest solution is that all communication is initiated from inside the customers lan. As little firewall configuration as possible. The best is if we can run without any special configuration as long as outgoing traffic from the customers lan are not blocked. If we need something changed in the firewall, we must be able to document that the change is secure. It doesn't have to be real time. Moving data in batches every ten minutes or so is OK. Data moves both ways, but not the same tables, so we don't have to support merges. It would be nice if we don't have to roll our own framework completely. Looking forward to hear your suggestions.

• Windows cannot open directory with too long name created by Linux

  - by Tim

  Hello! My laptop has two OSes: Windows 7 and Ubuntu 10.10. A partition of Windows 7 of format NTFS is mounted in Ubuntu. In Ubuntu, I created a directory under somehow deep path and with a long name for itself, specifically, the name for that directory is "a set of size-measurable subsets ie sigma algebra". Now in Windows, I cannot open the directory, which I guess is because of the name is too long, nor can I rename it. I was wondering if there is some way to access that directory under Windows? Better without changing the directory if possible, but will have to if necessary. Thanks and regards! Update: This is the output using "DIR /X" in cmd.exe, which does not shorten the directory name: F:\science\math\Foundations of mathematics\set theory\whether element of a set i s also a set\when element is set\when element sets are subsets of a universal se t\closed under some set operations\sigma algebra of sets>DIR /X Volume in drive F is Data Volume Serial Number is 0492-DD90 Directory of F:\science\math\Foundations of mathematics\set theory\whether elem ent of a set is also a set\when element is set\when element sets are subsets of a universal set\closed under some set operations\sigma algebra of sets 03/14/2011 10:43 AM <DIR> . 03/14/2011 10:43 AM <DIR> .. 03/08/2011 10:09 AM <DIR> a set of size-measurable sub sets ie sigma algebra 02/12/2011 04:08 AM <DIR> example 02/17/2011 12:30 PM <DIR> general 03/13/2011 02:28 PM <DIR> mapping from sigma algebra t o R or C i.e. measure 02/12/2011 04:10 AM <DIR> msbl mapping from general ms bl space to Borel msbl R or C 02/12/2011 04:10 AM 4,928 new file~ 03/14/2011 10:42 AM <DIR> temp 03/02/2011 10:58 AM <DIR> with Cartesian product of se ts 1 File(s) 4,928 bytes 9 Dir(s) 39,509,340,160 bytes free

• Distributing processing for an application that wasn't designed with that in mind

  - by Tim

  We've got the application at work that just sits and does a whole bunch of iterative processing on some data files to perform some simulations. This is done by an "old" Win32 application that isn't multi-processor aware, so new(ish) computers and workstations are mostly sitting idle running this application. However, since it's installed by a typical Windows Install Shield installer, I can't seem to install and run multiple copies of the application. The work can be split up manually before processing, enabling the work to be distributed across multiple machines, but we still can't take advantage of multiple core CPUs. The results can be joined back together after processing to make a complete simulation. Is there a product out there that would let me "compartmentalize" an installation (or 4) so I can take advantage of a multi-core CPU? I had thought of using MS Softgrid, but I believe that still depends on a remote server to do the heavy lifting (though please correct me if I'm wrong). Furthermore, is there a way I can distribute the workload off the one machine? So an input could be split into 50 chunks, handed out to 50 machines, and worked on? All without really changing the initial application? In a perfect world, I'd get the application to take advantage of a DesktopGrid (BOINC), but like most "mission critical corporate applications", the need is there, but the money is not. Thank you in advance (and sorry if this isn't appropriate for serverfault).

• How to send email from home ip when the email server isn't a designated outbound mail server allocated to BT Retail customers [on hold]

• Triple monitor setting in Linux with USB-HDMI adapter

  - by Oscar Carballal

  I'm trying to set up a triple monitor desktop at my office using Fedora 17, but it seems impossible, let me explain the setting: Laptop ASUS K53SD with 2 graphic cards, Intel and nVidia (Screen controled by Intel card) 24" Full HD monitor connected to the HDMI output (controlled by Intel card) 23" Full HD monitor connected to an USB-HDMI adapter (via framebuffer in /dev/fb2, apparently) VGA output (not used) controlled by nVidia card First of all, the USB-HDMI adapter works perfectly, it gives me a green screen (which means the communication is OK) and I can make it work if I set up a single monitor setting via framebuffer in Xorg. Here I leave the page where I got the instructions: http://plugable.com/2011/12/23/usb-graphics-and-linux Now I'm trying to set up the the two main monitors (laptop and 24") with the intel driver and the 23" with the framebuffer, but the most succesful configuration I get is the two main monitors working and the third disconnected. Do you have any idea what can I do to make this work?

• Few questions about a good projector on my PC and tv?

  - by jasondavis

  I have always wanted a projector for my tv, satelite, cable, and even PC in a spare bedroom. Well it's more of a home office that I spend most my time in and the catch here is it is a small room. Room is only the standard 8foot tall. Room is about 13 feet wide on the wall where I would like to mount the project and the wall where the screen would be for it. So only about 13 feet away from projector to screen. I would like to know... 1) From experience or knowledge what would be a good projector I could hook up to my satelite box and also my PC? Cheaper is better in this case but I would still like the best image for my buck and something reliable. There is no sunlight in the room either to worry about. 2) From that distance of about 12-13 feet away, how big of a clear picture could I expect? 3) What kind of cables would I need to purchase and run through my attic to my cable/satelite receiver box as well as my PC? 4) These cables in question 3 would most likely need to be a good 15-20feet in length to reach, would I need anything special for that to work at those distances?

• Timeout settings for Remote Desktop Sessions to lock

  - by atroon

  Our office uses a Windows 2003 server to provide access to an accounting application. Recently I was asked to increase the amount of time it takes for the session to lock itself and require the entry of the user's password to resume. That seems to be about ten minutes, at present. I am familiar with group policy and have tweaked those settings to scavenge sessions (and thereby licenses) from sessions that have been disconnected (by the user closing the mstsc.exe client or by a network issue). That's simple and straightforward. But I can't find anything in GP to allow a longer time period before the RDP client window goes black and then, when clicked upon, requires a username and password to resume the session. I must admit this would be nice personally as well, since most of my time is spent documenting the application and/or monitoring its database, so I usually have a window open to the terminal server along with the rest of the staff in the accounting center, but I interact with it very little. I usually enter my password 10-15 times per workday, but I'm pretty good at it by now. ;) So, can this timeout period be adjusted, or are we out of luck?

• CentOS Latency High Troubleshooting

  - by Sarah Weinberger

  I have two CentOS servers connected via a 10 Gb fiber optic cable with a network emulator connected between them. All three units sit on a desk in the lab. There is also a regular 1 Gbit Ethernet cable connected to each of the machines, which provide internet connectivity. When I set the latency to something roughly below 30 ms, all is fine. When the latency gets to 70ms and above, and definitely 130ms, the network layer suspends. For instance, if I set the latency (delay) to 70ms, then launching TeamViewer (or any other application that uses network connectivity) never happens or does not work. There is no timeout message, simply no response. I have to lower to latency back down to zero to see any response and have the box start working. What is the problem and how would I go about fixing it? It seems to me some sort of setting in Linux causes one of the CentOS networking drivers to sit in an infinite loop or something. eth0 is the connection to the internet, all settings are default eth2 is the 10 Gbit fiber optic connection to the other computer with the MTU set to 9600 with all other parameters at default values.

• How to make emacs accept UTF-8 from the keyboard

  - by Brent.Longborough

  My friends have persuaded me to "try again" (about the 5th time in about 12 years) with emacs. I'm currently suffering a little, and need help with emacs + utf-8. I'm running the 23.3.1 emacs gui on Windows 7 with my own custom keyboard layout (built with MS Keyboard Layout Creator). The layout has a full ISO-8859-1 (Latin-1) character set, plus some additional characters from ISO-8859-9 (Latin-5, gis etc for Turkish) and w for Welsh (don't know where that one lives). In my .emacs, I have (blindly) added these lines: ;; key board / input method settings (setq locale-coding-system 'utf-8) (set-terminal-coding-system 'utf-8) (set-keyboard-coding-system 'utf-8) (set-language-environment 'UTF-8) ; prefer utf-8 for language settings Now, when I enter characters from ISO Latin-1 from the keyboard, they are accepted without problems, but characters from outside Latin-1 are "translated" to an approximate character in Latin-1. Thus, for example, Latin-5 "g" gets converted to a plain "g". Cutting and pasting, however, work fine. Can anyone tell me what I'm doing wrong? I should like to make everything I do with emacs utf-8 with BOM.

• Is this way of using Excel 2007 Pivot table for BI scalable ?

  - by Sim

  Hi all, Background: We need to consolidate sales data across the country to do analysis Our Internet connection/IT expertise/IT investment is not quite strong, therefore full BI solution is out of question I tried several SaaS BI solution (GoodData, ZohoReports) and while they're good, they seem not to fully support what we need We're looking at 'bout 2 millions record for every 2 months My current approach Our (10) sites currently gathers data from all their branches and consolidate them into 1 Excel file with Pivot table and embed source data In HQ, I will request 10 sites to send back those Excel files periodically We will import those Excel to our MSSQL server There will be a master Excel file, that will also have the same pivot table (as those came from site Excel file), and datasource is the MSSQL server More details For testing, I currently use MSSQL 2008 Express on my laptop So far, I imported our transactions for the past 2 months and there are 2 millions+ row in 1 table in MSSQL (we just use 1 table, corresponding to our common pivot table structure). DB size is ~ 600 MB In the master Excel file, if not including the source data, it's just < 10MB. Including the source data will increase the size to 60 MB (so I supposed Office 2007 automatically zip the data ?) I try using the Pivot (drag-and-drop fields) and the performance so far is OK (my laptop specs: C2D T7200, 3GB RAM, Windows XP) So my question is : If we're looking at full year transaction (roughly 15 millions rows in MSSQL 2008 Express, 3.6 GB in size), is there any issue with that 15 million rows in 1 table in SQL Express ? Is there any performance issue with the pivot table at that time ? Can it still embed the source data ? (I google-ed but didn't find the maximum size of source data Excel 2007 can embed) Any other suggestions on how we can better do this ? Given that we can't afford the full BI solution, any light-weight/budget/SaaS BI that you can recommend ? Thanks

• How can I determine what is killing my network adapter win7 or vista?

  - by datatoo

  I thought this issue was like another person here, and that downloading the nvidia chipset drivers was the solution. However that is not all that is going on. This machine had Vista 64bit and is now Win7. Same issue with both. I have explicitly been denying network driver updates since getting things working again and when a Windows updates occurs on seemingly benign Office updates the adapter fails to work. Is the update process somehow protecting this machine by turning off things and it fails to recover connectivity after a restart? All that seems to ever work is a system restore. Which does work. Since there are 25 pending updates asking to do there thing, I hate to think this is a one by one update test to find the culprit. Any ideas? This has an integrated nic, video, and I guess audio on the motherboard. ES5200 intel cpu on a gateway 4800-05e I am not quite sure how to determine the actual network adapter. This is a wired adapter. I suppose worst case I can try another adapter if this keeps happening.

• SSH session becomes unresponsive when logged into Ubuntu Server virtual machine using VirtualBox

  - by nickbart

  Hi everyone, I'm really at my wits end here, so I'm hoping someone here can help me. I have a virtual machine running Ubuntu Server 9.10. It's just a small development environment so I can keep my code separate from the test and production environments. I am running it through VirtualBox 3.1.6 on a laptop running Ubuntu Desktop 9.10. I have it set up with a bridged network connection and it is bridged to my laptop's wireless adapter. We have no wired connections in this office. I boot up the VM and everything is fine. I can SSH into it using gnome-terminal and for a while everything is Kosher. Then seemingly randomly, the SSH terminal session with hang. No error message, nothing; it just becomes unresponsive. If I go to the VirtualBox terminal I find the VM itself is perfectly fine. It can ping and I can SSH out with it. If I restart the networking on the VM the SSH session in my gnome-terminal will most of the time become responsive again. Here's an interesting point, the SSH session will sometimes die right in the middle of me typing something (this points to it not being an idle session issue) and if I go to the VirtualBox terminal and restart the networking and then return to my gnome-terminal SSH session I find that it will come back to life and what I typed when the session hung originally will magically type itself in to the buffer. So, my input is getting stored somewhere and just can't make its way to the VM until the networking on the VM is restarted. I've tried different versions of VirtualBox and used vmdk images and vdi images and nothing seems to work. I can't tell if the problem is with my laptop, VirtualBox, or the Ubuntu Server VDI. Is there anyway to debug this issue? Or has anyone out there seen anything similar? Your help is much appreciated. Nick

• Windows Server - share files without access for administrator

  - by Pawel

  We have a MS Windows Server 2008 R8 based server that is administrated by our IT department. We would like to achieve two things simultaneously: A folder on the server, containing several thousand files (new files added frequently) that is accessible to some ActiveDirectory users (e.g. board of directors) but is not accessible by IT department employees IT department employees still maintain rights to administrate the server, including installing new software and services We already checked some solutions: Using NTFS access rights. Unfortunately IT (members of "Administrators" group) can set themselves as new owners of the files and change the permissions so that they gain access to the files. Enabling EFS. Unfortunately even if you do not allow IT to access files, they still can disable EFS completely because they have administrative rights. Moreover as far as I know you have to manually add permissions for all users but the owner for each new file - very inconvenient. Creating a new role for the IT department that has all the privileges apart from taking ownership of files. Unfortunately if you're not a member of the Administrators group, you cannot install new software, no matter what privileges you add to the role. TrueCrypt - nice free encryption software, but with poor sharing capabilities. You can either mount an encryption container on the server (and then IT has access to its contents) or you mount them locally but only one user can mount it for writing. AxCrypt - free encryption software that enables file-by-file encryption on the server. There are some disadvantages though - you have to manually encrypt each new file added. The files have their extensions changes. You can only set one password for all files (so all users have to know this one password). Any other ideas? Our budget is limited so enterprise-class software from Symantec or PGP would probably be not an option.

• EXCEL workbook, intermitently, takes 30 seconds to load

  - by Julio Nobre

  I am trying to figure out why a simple .XLS EXCEL workbook is taking, randomly, 30 seconds to open. Before answering: Please, bear mind the following: Problem symptoms Hanging is intermitent and it takes exactly 30 seconds; During hanging there is no cpu or disk activity; It only happens during workbook load. Every runs smooth after that; Windows Explorer.exe hangs on folder, but all other folders, system and applications are still responsive; There are no consecutive hangings. I have to wait for while to reproduce this behaviour; All workbooks where located on a local drive (C:\BPI); The workbook has no macros and no addins; Office 2003 is being used for several years; The computer is running Windows XP; Computer has several network mapped drives, all addressed to main file server; Recently, main fileserver was replaced by Windows 2011 SBS Standard Edition What I have done so far I have traced machine Explorer.exe, using Process Monitor, added Duration column, and filtered by Duration 1. That's is how I found that hanging was taking exactly 30 seconds. For further information, please refer to Oliver Salzburg tutorial. Using Process Monitor, I have also figured out than five operations were taking most of sample collecting duration. Looking at sample image below, column Operation below you will notice that one single operation was taking 29 seconds; I have tried different workbooks (all of them smaller than 30 KB); I have, temporarily, removed all shortcuts on User Document's folder that were pointing to network drives or shares; I have runned CCleaner to fix registry issues; I made sure that there were no external links on tested workbooks; I have reproduced this behaviour for hours; I have extensivelly researched for hours on the web; Process Monitor's collected and filtered data

• How do you use VIM to edit tabular data (tables)? Specifically, BIND (named) DNS db files.

  - by Richard Bronosky

  I'm usually a purist when it comes to vimming. I don't like remapping keys, or learning to rely on a bunch of plugins. I like to feel just as powerful on foreign boxen as I do on my own dev box. I do, however, believe in syntax files. Even though the solution may not be a syntax file (bindzone.vim is what I use), I want it bad enough to do whatever. I regularly view or edit tab (or comma, but that would be a bonus) delimited data. I hate having to set my tabstop to some ridiculous number in order to have everything line up. Example: The BIND zone files are ~40+,6,2,5,15+. So, even though I could view them on a single screen, if I set ts=40, I cannot. I have been searching for a "dynamic tab size" solution for years, but no luck. I hate that my only good way of editing or even visualizing tabular data is to scp it to my work station and open it in Open Office. There has to be a better way.

• Unable to access network resources through VPN

  - by fbueckert

  I'm currently attempting to connect one of our computers in the office to a client VPN. My development machine is running Windows 7, and can connect and see resources just fine. The problem computer is running Windows XP. They're both within the same network. Using the same credentials at both computers, the VPN connection (using the built in Windows network connections) works just fine. So far, so good. An IP address is assigned, and comparing both machines shows they're still in the same subnet. The problem is that the XP machine cannot see ANY of the computers in the client network. I tried a tracert to a target machine on the Windows 7 box, and the first item that comes up is the .0 address. Pinging it gives responses. Trying it on the Windows XP machine, however, comes up with just timeouts. Trying to trace to www.google.com allows the address to resolve (probably part of the cached resolutions), but results in just timeouts. I double-checked to make sure that the Windows firewall was not on, and trying to open the settings brings up a notification that the firewall service wasn't running, which leads me to believe that it's definitely not on. From my best guess, I've managed to connect the XP machine to a black hole of some sort. There's obviously something strange going on, but I'm not sure where I should be looking.

• Python not Working in Vim

  - by jdg

  I have a new install of VIM from the automatic windows installer: gvim73_46.exe I have Python 2.7 (32 bit) installed. If I open gvim, and type: :set python? I get E518: Unknown option. If I try typing: :python 'hello' Vim crashes. What could be wrong? Here are the contents of :version in case they are helpful, although python is installed, and it is using Python 2.7. I also checked, and C:\Windows\System32\python27.dll is where it should be... I am really lost here. Does anyone have any ideas as to what is going wrong?

• ADSL Modem/Router sometimes hands out incorrect IP addresses

  - by Peter Keevill

  My setup is as follows:- Main ADSL modem / router (switch) configured as DHCP server with address range 192.168.0.25-60 The office machines are configured with fixed IP ( not in the same address pool of course ) and hard wired to this router. A wireless access point ( Router ) is connected to provide Internet access for guests in a separate area. This router is NOT configured as a DHCP server. Wireless authentication is turned off. IP address lease times are set to 4 hours. Sometimes guests are able to connect to the wireless access point but they are not given a valid IP. They get 169.x.x.x addresses. Rebooting their machines does not resolve the problem. The only way to resolve is to reboot the main ADSL/router which is often frustrating for other users who are successfully connected with valid IP and DG. The problem seems to occur more frequently to Apple/Mac guests although it also sometimes occurs with Win machines. I personally use Ubuntu on my Laptop and thus far, never have had any problem connecting and getting a valid IP address in the guest area. One further point of note which may give a clue is that certain guests ( always Apple/Mac ) get lease times of 90 days. However, this does not 'stack out' the number of available addresses and of course, rebooting the router clears them until the next time they login.

• Reconnecting OST with Exchange

  - by syrenity

  Hi. I have a quite big problem with customer's MS Exchange. The server got it's disk filled about 2 weeks ago, so it's currently offline. They plan to upgrade it, but not in hurry, as they use it mainly for OWA and back-up - the mails exchange is done via SMTP and POP3. Trying to diagnose some problem today, one of the users has (following the ISP instructions), removed the Exchange account from Outlook, which essentially left the OST orphaned. The user naturally didn't move the emails or any other data to the Archive / PST before, so these emails located on the OST only. So currently I'm trying to figure out how to restore them. There are 2 options: 1) Make the user buy some tool to convert them to PST, and import as archive / main Outlok file? 2) Reconnect the Outlook to Exchange (once it up), let it sync the old server content, then shutdown Outlook and replace the new OST with the old one, start Outlook again in offline mode and move these files to archive. 3) Any other method? Can someone advice what would be the best approach here? The used versions are Outlook 2007 and Exchange 2003. Thanks!

• VMWare Setup with 2 Servers and a DAS (DELL MD3220)

  - by Kumala

  I am planning to use a VMWare based setup consisting of two VMWare servers (2 CPU, 256GB Memory) and a DAS (DELL MD3220 with 24x900GB disks). The virtual machines will be half running MS SQL databases (Application, Sharepoint, BI) and the other half of the VM will be file services, IIS. To enhance the capacity of the storage, we'll be adding a MD1220 enclosure with another 24x900GB to the MD3220. Both DAS will have 2 controllers. Our current measured IOPS is 1000 IOPS average, 7000 IOPS peak (those happen maybe twice per hour). We are in the planning phase now and are looking at the proper setup of the disks. The intention is to setup up both DAS one of the DAS with RAID 10 only and the other DAS with RAID 5. That will allow us to put the applications on the DAS that supports the application performance needs best. Question is how best to partition the two DASs to get best possible IOPS/MBps, each DAS will have to have 2 hot spares? For the RAID 5 Setup: Generally speaking, would it be better to have one single disk group across all 22 disks (24 - 2 hot spares) with both controllers assigned to the one disk group or is it better to have 2 disk groups each 11 disks, assigned to one of the two controllers? Same question for the RAID 10 setup: The plan is: 2 disks for logs (Raid 1), 2 Hotspare and 20 disks for RAID 10. Option 1: 5 * 4 disks (RAID 10), with two groups assigned to 1 controller and 3 groups to the other controller Option 2: One large RAID 10 across all the disks and have both controllers assigned to the same group? I would assume that there is no right or wrong, but it all depends very much on the specific application behaviour, so I am looking for some general ideas what the pros and cons are of the different options. IF there are other meaningful options, feel free to propose them.

• Why do hosts prefer Linux to Windows Server?

  - by iconiK

  So far I see a HUGE majority of hosts provide only Linux shared hosting, providing Windows only to VPS (or even to only dedicated servers). Why is it so? While Windows is a lot more expensive than Linux (though it depends on a lot of factors, not just initial and support license cost), it also provides ASP.NET, IIS and of course, Microsoft SQL Server. I know in the past it might have been because of cPanel being Linux only but now they have a Windows version. But still, why is Linux predominantly used on shared hosting? PHP works on both systems. IIS can be (and probably is) faster. MySQL runs on both systems as well. cPanel has a Windows version. Python, Perl, Ruby, all run on Windows as well. You even have MS SQL Server Express, which I find more superior than MySQL in both speed and features. Access is there for low usage requirements, as is SQLite (which is so great for quick small stuff). And with PowerShell you have a good alternative to the Unix shell. EDIT: I am looking for common reasons, I realize each hosting company (and/or it's clients) may have different needs. This becomes very important when you get to VPS or Cloud which give you a full operating system to use.
