Sulla political dell'IO Scheduler knew linux

Ciao a tutti, UN amico mi ha reported following che I consigli che if exposed in questa KB ha visto notevoli improvements nel suo caso.

http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 2011861

In brief nella KB if spiega che by the linux VM, especially is fanno IO intenso, cheap cambiare he modo in cui lo Scheduler dell'io gli accessible disco, using quella piu 'trivial' since in modo da abdicating manage Attività di IO all'Hypervisor.

Qualcuno ha gia tried a fare questa cosa e ha delle McNeish da share?

Ciao,.

If fa parte delle mie ottimizzazioni sulle macchine linux standards: noop scheduler lo uso.

In general the e logica' di far if the Attività che' di I/O nothing completely gestite da vSphere che può ' Winegardner "in the large" (ha sotto it controllo OUA tutti I datastore) respect alle single vm linux che per forza can ragionare solo como is he ditch disco tutto dedicated a loro.

In General ho visto prestazionali improvements in caso di con vm I/O intenso e/o quando he number of vm linux e' "significant."

  • Dell XPS630i boots with linux fix not XP or XPinstall or OEMinstall

    [first of all, sorry if this ends up the double post, gui posted in the wrong forum]

    a virus then another then 2 bad sectors on the startup disk.

    new 3rd party raid1 with 2 new drives from Samsung

    Installed XPsp3 and the system worked

    next start gave no windows/system32/config/system

    can use partedmagic and show everything except the boot drive, I could earlier.

    I had been preparing make the copy overs up to the failure.

    Have run some tests on memory to no information.

    Pulled the memory removal and spot replaced to check.

    removed 3rd party raid installation and used on board Nvidia.

    [this require a pilot custom start?]

    Now cannot boot from a hard drive or raid, the first-reinstalle XP prior to purchase of raid, gives no hal.dll error which I did not yet have time to correct.

    Another gets in, select boot, F12, disk boots, on adfinitum.  Cannot make sure, only in F12 menu and see and start the FD, USB, disc and HD without result, and enter the Bios.

    I put the BIOS back to default and tried a raid not HD, then added raid and tried the Raid1.

    If I put a blank formatted disk and try to boot from the installation discs, always impossible to get anything to boot.

    Install disks make through the support of the Executive, and then restart the startup so that I can't start XP OEM or XPsp2 to attempt a repair.

    Yet once parted works very well and can do a lot of utilities and everything seems to check out.

    Is my next step to format the partition and try to reload the RAID1 again?  Oh it's true, nothing starts.

    Somewhere along the way he also reported well being in good health and have a glitch.  It does not now rise in Parted.

    It's pay back me to the years of no viruses to be attentive and no disaster to stay in front.

    Please help.  TIA!

    Hello

    If you are unable to start on different known good hard drives once you have formatted the drive completely, then, it might be a problem with the cable or the motherboard.

    The user can contact its manufacturer support.

    Thanks and regards.

  • Ubuntu linux driver installation for Nvidia 950 M on Dell Inspiron 17R SE 7720

    Hello

    I bought a Dell Inspiron 17R SE 7720 Ubuntu version because I like Ubuntu linux more than Windows.

    I can't find the linux drivers that will allow my Nvidia GT 950 M graphics so, basically, the card useless and no power management.
    There is absolutely nothing for Ubuntu Linux on your drivers page.

    I have updated to the latest BIOS A03.

    The laptop's Ubuntu Logo sticker on it next to the Intel i7 so I thought it is totally compatible.

    Please advise,

    Thank you

    Andrei

    Optimus system and at the present time, it is not properly supported under Linux, there is work in progress for him, but for a workaround, see Bumblebee project: wiki.ubuntu.com/Bumblebee

    Description a little longer: you have two graphics - integrated (Intel) and discreet (Nvidia). Optimus systems are designed with the intention to use the GPU integrated tasks that requires no graphic heavy treatment (most of the day-to-day activities) and the use of the discrete GPU for applications requiring more powerful GPU. Integrated card is less eager for power and voltage GPU discreet when not in service allows cooler use.

    Normally you use integrated card and there is no way to use the card nvidia directly if the BIOS does not switch to it. Help Optimus allows to use the Nvidia card for rendering and power down to save power when not in use. It has not been official for Optimus of Nvidia Linux support. Bumblebee is a community created project attempting to address the issue, but it is really only a workaround until the solution has been created. FIRST is such a solution, but at present it is still experimental and is not in any version of Ubuntu, more it is officially supported only in the open drivers source (new), Nvidia has not yet validated supporting in their binary driver.

    I agree that Dell support for bids Linux pages are sorely lacking, in fact I was not able to locate a page describing their Linux pre-installs. Ubuntu certification pages are not really informative on Dell changes and upgrade policy.

  • Installation of Linux on a XPS 8500

    Dear Dell,

    I just replaced my old Dell Dimension with a new 8500 XPS at great expense. On my old size, I was able to load Linux on a completely separate drive. When I tried to boot into Linux, I was able to change the boot priority and start Linux. However, to my dismay, I can't do this on my easily on XPS machine. I bought this machine to do with it as I wanted and not be attached to the use right of Windows 8.

    From my understanding, this can be achieved by disabling Secure Boot or any DELL call, but it is true that, without the protection of start-up scheduled. My understanding is correct?

    What I'm looking for from DELL is on how to do it. I'm not asking DELL how to install LInux, but I am looking for guidance on how to. to get my machine in position to do it and the ramifications to do. I install Linux on a completely separate disk so as not to disturb the 8 installation of the window.

    When I bought the machine, nothing on the website to indicate how blocked in the operating system of the window that you are. I think that DELL has a duty of care to help customers who are in this position is to say be bothered using the PC for other uses, which should fall to the consumer.

    I know I'm not the only customer that wishes to do this and your help in this matter is greatly appreciated.

    If you change the UEFI boot in legacy Mode, you need to reinstall Windows 8. So you can image of entire hard drive before doing this, just in case you decide to cancel...

    Unfortunately, other manufacturers of PC and Dell are stuck with many things forced on them by Microsoft.

    You may search these forums for further discussions on installing Linux on the XPS 8500.

    If you Win 8 Pro or Ultimate, you have right to demotion free for Windows 7 Pro, which might be more tolerant of your dual-boot arrangement. But you will need to install Win 7 in traditional way with Secure Boot disabled in the BIOS.

    Without Secure Boot enabled in BIOS, you'd be no more at risk you'd be with Win 7 on any old PC version.

  • HP3521: HPLIP install not on Linux Mint 18 with XFCE

    I try to install HPLIP on a laptop Dell Latitude D510 with Linux MInt 18 with freshly installed XFCE.  Towards the end of the HPLIP installation, I get the following error message:

  • I'm about to wall mount my Dell W4201C &amp; need info on how to remove it from its support?

    I came across this forum hoping someone here enlighten me on how do to remove the 4201 C of its stand, so I can mount it on the wall.  When I received this TV a couple of years ago, he came with a mounting kit wall head but I just never had the courage to tackle mount my baby to a wall - so far.  I had the solidedly of support attached to two poles with 4 bolts provided last night.  Tonight, I'll have my son help me lift & lock in the wall plate but I (obviously) need to first remove the furniture.  Looking at the piece of furniture that is connected to the screen, I'm not sure if the two screws down that align with the support legs are that it secures for now or not.  I've always distrusted of simply by unscrewing things just to see what happens, I played have before getting internal parts to go where they are supposed to go because sometimes a screw has a different purpose...

    BTW, the stand was prefixed to the display when we removed the box otherwise I could remember what I did to tie in the first place!  Thanks in advance for your help/advice.

    p.s. I have owned my Dell W4201C TV since Christmas ' 06 & still love! Thought I'd get that road after reading some of the questions some owners have had televisions w/Dell.  I knew none of the questions & hopefully will remain free of problem for the full 60 k hours! Thanks again!    8-)

  • Neofita con Vsphere by UN progetto important

    Ciao a tutti Ragazzi,

    new del forum e sono sto moving I primi passi con lo software spettacolare VSPHERE.

    is DIO Vuole, devo migrare far da server substitutes a virtuale vsphere rete di un client important struttura.

    I like tight far client al essential licenza vpshere + 2 new servers (hosts); E probabilmente anche veembackup, Reed is non trovo rete delle guide pero ho alreadyà che don't parlate molto bene.

    In hoist ho put it progetto fatto e che I like mettere in piedi, my non mi è chiaro features dei Server di cui ancora ho need

    VI list the che mi servirebbero Vm in modo che gentilmente possiate consigliarmi quali servers andrebbero bene...

    (VI prego di rispondermi alle request che vedete in basso)

    -HOST A = 1 VM = Linux Ubuntu Server 12.04 e a SAMBA PDC (da 1 processor 2 VM + 4 GB ram + hd 500 GB)

    -HOST B = 1 VM = Windows Server 2008 R2 (portion by far run UN gestionale sql a cui here if collega anche da remote) + Server Vcenter (VM da 1 processor core, 4 GB ram + 100 GB hd 2)

    -HOST B = 1 VM = Windows 7 Professional x VM Backup veembackup (da 1 processor 2 VM + 4 GB ram + hd 50 GB)

    -HOST A = 1 VM = Windows Xp Professional (remote pc by white dati giuridiche) (da 1 processor 1 VM + 2 GB ram + hd 25 GB)

    -HOST A = 1 VM = Windows Xp Professional (remote pc by white dati giuridiche) (VM da 1 di 2 GB hd 25 GB of ram + cpu 1 core)

    REQUEST:

    (1) il Vcenter posso installarlo sulla gestionale del VM? o serve una dedicated vm?

    (2) Veem Dove backup going free? Known una macchina fisica o dedicated basta una vm? to mi down the host in cui spinning the vm con veem, riesco solo dal a plane ticket he NAS QNAP recovery? oppure veem by fare recovery ha need del pc in cui e da?

    (3) the risorse assegnate alle vm del progetto vanno bene secondo Voi?

    (4) secondo Voi mi bastano degli HOST con dei e image 16 GB di ram by it project? Mi servono degli Esa-core by reggere bene oppure all the VM e poter guarantee che quest' ultimate girino bene nel caso in cui uno degli HOST sia fuori uso?

    (5) ARE: Simulando che A ESXi Host goes to low e con VeemBackup tiro su dal NAS QNAP altre vm che mi servono e the Moussa sul NODO ESXi B che remains acceso, quest'ultimo regge bene all the vm?

    (6) per problemi di budget Reed tutti i brain sono SATA SAS instead... This will be big differenze di prestazioni nei backup notturni? Nel Miss delle macchine dal nas?

    Sempre 7) by budget, sono che cerco Server dei giorni di problemi da 4core e 6core, ho visto dei DELL, FUJITSU, IBM E HP proliant, my a di meno 1400 euro + iva nn ce nulla... (senza hdd e raid.) ; so che devo cercare material certificato vmware, not being expert di vsphere ho he nebbish che in caso di ko di UN altro non mi regga host all the vm con UN server a 4core xeon...

    (8) mi potete cortesemente consigliare some modello di Server da usare come from the hosts, che costi non molto?

    Devo fare it al preventivo client entro the next week, my ho questi doubt nella testa...

    Ringraziandovi in pre-empted, spero che possiate help very.

    Ciao

    Momo

    (4) secondo Voi mi bastano degli HOST con dei e image 16 GB di ram by it project?

    her somma delle ram delle macchine che vai a virtualizzare e 14 giga quindi sono molto currently o surdimensionate o tutte knew a host girerebbero probabilmente a fauvergue.

    Vedrai che quasi sempre risorsa che if esaurisce prima e ram, not the cpu. Quindi partirei con at least 32 giga by host.

    Quanto al vCenter, no lo mescolerei con altro. Oltretutto vuole ram UN 4 giga solo by him, di quindi I conti sopra sono sballati. SE he problema e di una licenza windows esiste the appliance risparmiare virtual vCenter.
