  • How long do servers usually last?

    - by AX1
    I'm trying to estimate ROI for a new server and how long it will most likely be in service. Are there any average numbers for how long you can expect a server to last that's in 24/7 use? In other words, is it likely to find 10-year old server from 2010 in today's racks? How about servers from 2005? I'd love to get an idea for how long a server will most likely be in use. By the way, this is meant irrespective of growing or changing application needs. I'm talking only about the hardware.

  • Different graphic cards drivers while booting from external media

    - by goran
    I am booting a certain system of mine with ubuntu 9.10 from external HDD. I am satisfied with the setup and it works fine, however I would like to modify it so that I can choose which graphic card drivers to load during the boot time. Specifically I would like to choose between: nvidia proprietary driver ati proprietary driver generic driver Currently if I am using proprietary drivers then dont boot into X, delete xorg.conf, start gdm and reconfigure the system using jockey (for hardware drivers). What would be the steps to make this (semi-)automatic and avoid restarting X?

  • mirroring linux server to external usb harddrive

    - by DuPie
    My google-fu must be sucking. i havent been able to find a good solution for the following: numerous Linux server on commodity hardware Trying to do a recovery mirror copy to external harddrives External harddrives are smaller than source harddrives, but larger than data External drives are connected via usb2 (slow) Servers range from 20GB of data to 400GB of data Servers are remote, so hands on access is a pain need to copy boot files. empty external drives currently Basicly, looking for a way to do use a ghosting solution from INSIDE a running linux server to an external harddrive, without booting a cd etc. the rsync/cpio solutions i've looked at dont work great with grub/dev/proc etc. I understand that since the system isnt offline, it wont be a "mirror" image as files change, but thats ok. Are there any free/commercial products that would work?

  • ATI Radeon HD 5970 Display numbering issues

    - by Arindam Sen
    I have 2 computers on which i have ATI Radeon HD 5970 graphics card installed. There is 1 VGA out and 1 DVI out in it. When I connect my VGA out to a monitor on my 1st computer, it shows it as display 1 and when I connect my DVI out to a monitor it show it as display 2 (I am using extended display). When I do the same thing on my 2nd computer it shows just the opposite. The VGA out shows as display 2 and the DVI out shows as display 1. Is it a problem with the drivers or the hardware? (because the graphics card on both is exactly the same)

  • erratic audio levels on windows vista

    - by old retired dude
    I'm somewhat hard of hearing. I've been listening to my windows Vista machine with a pair of headphones so I don't annoy the others. I have 2 issues: 1) the volume varies enormously depending on the source. Having a windows alert occur while I am listening to a DVD or Youtube is a painful experience. Is there a preferred way to set all the different audio controls so I have a more constant volume? I already have lowered the volumes of the windows alerts. 2)Is there a way to limit the volume of my headphones to protect what is left of my hearing? Is there a software solution or should I be going for a hardware limiter? thanks retired dude

  • Windows 7 on 1st Gen Macbook Pro (Q4-2008), power management problems.

    - by typemismatch
    I have the first generation macbook pro, purchased Q4 2008. I've been trying to run Windows 7 and can get it all installed great with the BootCamp 3.1 64 bit drivers however ... power management isn't great. The screen and keyboard don't automatically dim - the laptop gets too hot. I noticed on some newer macbook pros that windows 7 works perfectly and the above doesn't happen. Does anyone know if there really is a hardware issue with this 1st gen or is there some firmware update I can use to fix this? Thanks!

  • Netgear VPN can't access specific server

    - by Critologist
    I have a Netgear FVS318N configured with a VPN. I'm trying to access my call recorder with the provided software from another office. I've already setup the VPN connection, and it works. I can connect and ping the remote router and a few other things on the network. However, I can't ping or connect to my call recorder. If I move outside of the office network (i.e. connect directly to the cable modem or via a mobile hotspot), I can connect and ping the call recorder just fine. The office has a simple Linksys WRT54G router and is using AT&T Uverse. The remote location is using Charter Cable with a Netgear FVS318N. Has anyone ever encountered anything like this before? I've setup an identical VPN previously for a different client using similar hardware and never encountered this. Thanks in advance!

  • Bound external Cisco CIGESM ports to a specific BladeServer

    - by Vinícius Ferrão
    We have an IBM BladeCenter with 14 blade servers and one external Cisco CIGESM for Ethernet connectivity. Since this hardware is a little old, we will use it for other services, and we want to run a pfSense instance on one of the blades. It's just an Firewall Appliance, but it needs two network interfaces: one for the WAN and the other one for LAN access. Our architecture works on top of static routes, we don't use NAT, so we got the WAN IP in one interface routing to the another one. The main problem is how to plug the WAN cable in one of the four external ports and make it exclusive to the blade server containing the firewall. And we also need an exit port that goes through a 3COM 4200G switch that makes the internal routing and VLAN separation. Thanks in advance

  • Why has ESXi 5.0 not used the software RAID configuration on my test server?

    - by kafka
    I've got a test server which was running WS 2008 Enterprise on the bare metal. It was correctly using the software RAID 1 configuration (2x250 GB disks which appeared as one disk), setup on the Dell Poweredge T110 (which meets compatibility requirements) without requiring any extra setup from me. (As an aside I'm fairly sure it's software RAID, as we didn't spec a hardware RAID controller, if that's of any importance in this situation). I am now testing installing ESXi 5.0 on this server to run some VMs. I've successfully installed ESXi, and imported a VM fine, but it's showing 2 x 250 GB disks available as datastores. However they should be appearing as one volume. When I boot the server, there is a RAID configuration screen you can enter, and I'm guessing this is what I'll have to do at some stage, but now need to be very careful because there is one disk which contains data that I want to be mirrored on the other disk. What is the best thing to do in this situation?

  • Setting up Raid 1 Array for Home Server

    - by user1048116
    I'm not sure if this is even possible, but it's worth asking on here! Essentially I have a old machine at home (well, not old hardware wise, but I recently built a new gaming rig), which I decided to install a copy of W2008 R2 on and use as a file/backup server and media center'ish machine. As of now, it has a single drive partitioned into C and D, with D being the Data partition. I have happened to find an old 1TB SATA drive lying around at home, and was wondering if it's possible to setup a Raid 1 array in my rig within Windows without needing to lose everything on my first drive (or maybe even just mirror a specific partition, say the Data partition, as this is just what stores my photos etc). Maybe this isn't possible, but you never know :) Regards, T.C

  • Win 7: Share internet connection via Ethernet and WiFi

    - by Anvaka
    I have the following configuration: Box 1. Running Win 7, connected to the Internet via Eth0. Has one wireless network adapter and one another ethernet adapter (say, Eth1). Box 2. Running Win XP, has one ethernet adapter. I'd like to share Internet connection of the Box 1 with Box 2 via cable and have box 1 also sharing the Internet with other wireless devices. I don't want to buy any additional hardware. Is it possible? PS: Sorry if I'm unclear. I merely know nothing about NAT and network administration.

  • How to set up my network/bridging using Apple Airport equipment?

    - by John
    I'd like to set up my network like this, and I want to make sure it's possible using the hardware I have. I think it should be... I've got my cable modem in one room. I want to plug it into an Apple Airport Express and create my wireless my wireless network here. The airport express will do the NAT and DHCP. By my TV there are a few things to be networked (Xbox and Tivo). I have an airport extreme here. I'd like to have the airport extreme join the wireless network and share the connection to the ethernet ports. Can anyone provide some assistance on the best way to configure to do this? Thanks!

  • Remote access to BIOS?

    - by j-g-faustus
    I have a home server running headless (i.e. without a monitor), using ssh for remote access. This works fine most of the time, but I still need a graphics card and still need to drag out a monitor whenever I have to access BIOS, (re-)install the OS and similar. I know that there are business servers that let you control everything remotely (over Ethernet), including power up and BIOS access. Is this type of functionality available for "prosumer" class hardware? If so, where does it sit - should I look for motherboard support, a PCI-e card or an external device? And does this type of functionality have a name, so I know what to google for?

  • Text template or tool for documentation of computer configurations

    - by mjustin
    I regularly write and update technical documentation which will be used to set up a new virtual machine, or to have a lookup for system dependencies in networks with around 20-50 (server-side) computers. At the moment I use OpenOffice Writer with text tables, and create one document per intranet domain. To improve this documentation, I would like to collect some examples to identify areas where my documents can be improved, regarding general structure and content, to make it easy to read and use not only for me but also for technical staff, helpdesk etc. Are there simple text templates (for example for OpenOffice Writer) or tools (maybe database-driven) for structured documentation of a computer configuration? Such a template / tool should provide required and optional configuration sections, like 'operating system', 'installed services', 'mapped network drives', 'scheduled tasks', 'remote servers', 'logon user account', 'firewall settings', 'hard disk size' ... It is not so much low-level hardware docs but more infrastructure / integration information in these documents (no BIOS settings, MAC addresses).

  • Windows 7 upgrade advisor issue

    - by Groo
    I am preparing to migrate a pretty old XP machine to Windows 7. I ran the Windows 7 Upgrade Advisor and got a couple of smaller issues (low 512Mb RAM complaints and similar stuff). Apart from that, everything else was shown as compatible, including my old ATI Radeon 9550/X1050 card: ATI Radeon 9550/X1550 Series: This device is compatible with Windows 7. The thing that concerns me is that people around the web seem to be unable to actually find a Windows 7 driver for this card. Even the ATI web page states that this is a legacy device: If the user chooses to, they can install the ATI Catalyst Windows Vista graphics driver under Windows 7. [...] Using the ATI Catalyst Windows Vista driver under Windows 7 is not officially supported by AMD [...] Should I trust the Advisor and continue with the update? Does this mean Microsoft will provide at least a generic driver which will allow hardware acceleration with this card?

  • What would you use to keep track of all the random information about your LAN/Enviroment?

    - by agnul
    Say you work in your average anarchy... no appointed IT guy, no Office-Manager whatsoever, just developers working in free-for-all mode and a couple of non technical people around for admin (non IT) stuff. What would you use to keep track of Hardware / Software inventory Backups of OS images, Drivers, and all that LAN configuration information Passwords for all the systems Currently I'm thinking of having some sort of wiki + web server on our only ''server-class'' machine, but then I fear I'd be the only one who would go through the hassle of adding information in the wiki... So, have you been through that? What would you suggest?

  • How can I troubleshoot SSD disconnection problems on Windows 7?

    - by 0xC0000022L
    I have a small SSD (Transcend StoreJet TS256GESD200K) which I am using on several computers. The drive is formatted with NTFS and recently I started noticing disconnects. Normally one probably wouldn't notice (you don't even get the notification sound in Windows when it disconnects), but since I use USBDLM and run a VM from that SSD, I get to see this first-hand. How could I best figure out whether the problem is the hardware (SSD, USB socket, USB cable or something in the PC) or software? In short: how can I locate the source of the disruption so that I can work on removing the problem? Side-note: SMART status for the SSD is clean.

  • Can I use the voice & SMS features of my GSM SIM through my laptop?

    - by i..
    My laptop (a Lenovo T410s) has an internal GSM modem (device manager calls it a Qualcomm Gobi 2000 HS-USB Modem 9205) that I'm currently using a regular (voice, data, text, etc) 3G SIM in. The data functionality works great through the Lenovo software & Windows 7 but I was wondering if I can use the other features (specifically voice & SMS) through Windows. Is it posisble to use the non-data features of my 3G SIM through my Qualcomm GSM modem? If so, what software is available to this end? If not, where is the restriction? (e.g. hardware, OS, driver, software) Thanks!

  • Can i create a virtual machine on my laptop to be used with another monitor?

    - by Ranhiru
    OK, the scenario is like this... I have my laptop... and I have another user without a unit. He has only a keyboard, mouse and a monitor. Is there anyway that I can make him use my computer by creating a virtual environment which he will access, BUT, without interfering with my work. I use my laptop and view my OS from the laptop monitor. I create a virtual environment (some OS probably XP) and run it. The virtual environment is displayed in the connected monitor and the other user uses it using the extra keyboard/mouse and the monitor but without interfering my screen! Is this possible? Stupid? Futuristic? Need more hardware?

  • Feeding the kernels entropy source from other machines and/or increasing its maximum size

    - by David Spillett
    We have has a little trouble with a small box that acts as a VPN end-point and mail relay for our network, caused by the available entropy for /dev/random being too low (which causes TLS connection attempts by exim to fail). The machine doesn't do anything else, so the normal feed into the entropy pool (interrupt timings from things like disk access) is not enough. As a quick hack I've set a looping script that reads from /dev/hda at a couple of Mbyte/sec which keeps it topped up. Other than buying a hardware RNG, is there a clean way of piping data for entry from elsewhere, such as a copy of the data our file server uses for its entropy source? I've spotted several tips for using rng-tools to feed it from /dev/urandom on the same machine but that "feels dirty". Also, is it possible to increase the maximum pool size? It currently seems to max out at 3585.

  • Filtering serial port io

    - by mr odus
    I am currently working on a project where I communicate with hardware via a com port on its respective pc(win xp or 7) It is a fairly large project and sifting through the log file can be a bit of pain. This is my current setup. I use putty to do the actual serial communication, and write it to a log file. Then using MinGW Msys I filter it using tail -f "puttyLog" | grep -i "search term" Is there a better way to do this? I mean specifically filtering the input in realtime. Not that mine is terrible, but it still involves having to read from a log and sometimes there have been hangups where it will be delayed for a minute or 2. I have used software in the past with a main io window and then internal filter panels, but can no longer remember or find it.

  • Cisco redundancy modes

    - by user974896
    I am using a Cisco 6500 series with an SSO redundancy configuration. The show redundancy output is as follows: Hardware Mode = Duplex Configured Redundancy Mode = sso Operating Redundancy Mode = rpr Maintenance Mode = Disabled Communications = Up I would assume the device is operating in RPR mode although SSO is configured. What could cause this? Shouldn't the operating mode be SSO? EDIT (show redundancy states): my state = 13 -ACTIVE peer state = 4 -STANDBY COLD Mode = Duplex Unit = Primary Unit ID = 5 Redundancy Mode (Operational) = rpr Redundancy Mode (Configured) = sso Redundancy State = rpr Split Mode = Disabled Manual Swact = Enabled Communications = Up client count = 60 client_notification_TMR = 30000 milliseconds keep_alive TMR = 9000 milliseconds keep_alive count = 1 keep_alive threshold = 18 RF debug mask = 0x0

  • Which SATA controller is better to use with Windows Server 2008 R2 64 bit?

    - by at8eqeq3
    We're preforming some hardware upgrade on our server machines. As a part of this process, we have to install some additional disk drives. Unfortunately, total number of drives will become 7 or 8, while all of our motherboards have only 6 SATA ports. Obviously, we need additional disk controllers. For now, we've tested Silicon Image (actually, no-name) and Adaptec controllers, both on SiI3132 chip, and got some problems with drivers for them: Silicon Image drivers are not installing at all, and Adaptec ones are installing, but the system says they're not signed and becomes unbootable. We're tryed both drivers from controllers' CD's and latest versions from manufacturers' websites, and no luck. So, can you recommend some SATA controllers that will really work without tambourine dances on mentioned OS (we need just 2 SATA ports and PCI-E, while RAID and any other features are no-matter)? Thanks for any help.
