How to recover from the failure of a with ESXi USB flash drive?

I have ESXi 5.5 running on a 16 GB USB flash drive.  The system itself has a RAID card and drives mirrored where all virtual machines are stored, so it seems to me that a critical point of weakness is the drive itself.  If die ESXi itself running flash player, is there a procedure to recover the virtual machines on the disks?  Or should I keep a backup of my drive as well?

  1. How to restore the operating system assuming that the flash drive fails? If I reinstalled ESXi on a new drive of the same thumb, would see the VMware VMs existing on the hard drives of the server? Or is the process of discovery of the relatively painless existing virtual machines?

If your flash drive goes down, will not be a problem that you have your virtual machines without danger on the separate data store in the locally attached storage drives. all you got to do is to reinstall ESXi host, he will be happy to see the existing VMFS data store and browse this data store where are stored the re-save you and virtual machines in the inventory.

See also changes following KB to make the backup of your ESXi as operating system configuration and when you change the configuration at the time of the failure of ESXi, you don't have to worry about re-configuarting it

VMware KB: Backup and restore configuration using the vSphere command-line Interface and vSphere PowerCLI ESXi

  1. How can I maintain redundancy for my USB failure? Can I have two drives connected and automatically backup flash / mirror the first hard drive to the second?

This is not possible (I never tried myself) If you use an external flash drive, but let's say that you have any material to the specific provider giving this feature as

DELL IDSDM http://www.dell.com/downloads/global/products/pedge/en/poweredge-idsdm-whitepaper-en.pdf

or another supplier giving a similar feature, then it is quite possible to mirror. Otherwise, the best option is take config. backup using KB, I mentioned in the first answer.

    How to replace a bad IDE disk with a USB Flash drive system - and have all the functionality of XP Pro SP3
    Given a PC without hard disk...
    How can you use a flash drive instead?
    So, indeed, the USB key works as an SSD...
    I saw online options that gives partial functionality of the system... and an option that is more than $100 (more than the system's worth)...
    None of these options are acceptable in the circumstances.
    It is an effort to create a machine for a particular use, built from a recycled pc for which hard drive was removed and destroyed by the original owner...
    The criterion is that it must work just like it was a mechanical drive running xp pro sp3 with all updates, etc...
    Thanks for any help.

    You can not install XP on a Flash as his unsupported drive. Your only two options are a traditional hard drive or Solid State Drive (SSD).

  • How to use a blank disc DVD-R as a USB flash drive?

    Hi all! I'm running Mac OS X 10.9.5 on my MacBook Pro and I was wondering how I could use a blank DVD-R disc as a form of rewriting for documents, music, spreadsheets, etc. ? My mac Let's burn me to the disc, but I can't rewrite to it after that. Help, please!

    They don't work that way. Rewritable means simply you can erase the disc and use it again. You can't write it during normal use of the disk. This, to a USB flash drive.

    To be same rewritable, you can use a DVD - RW, DVD - r not it is not rewritable. You can look for third-party software that allow you to use the drive as a flash drive, but I am not sure that these programs exist. Not much need for it.

  • How do you know the speed of read/write of a flash drive?

    Who knows a program to read/write speed?

    Hi Cristi,

    Thanks for posting in the Microsoft Community.

    An indication of the standard flash drives read/write speeds is the following:

    USB 2.0:

    Sequential write speed range = 4-10 MB/S

    Sequential read speed range = 15 to 25 MB/S

    USB 3.0:

    Sequential write speed range = upto20 MB/S

    Sequential read speed range = upto45 MB/S

    These reading and writing speeds offer a guide to the read/write Flash Drive performance and have been identified in recent tests. Please note that we are changing the components USB Flash Drive at any time based on the availability and cost. This means that the read/write speeds above cannot be guaranteed.

    You can use your favorite search engine to search for this application that measures the speed of read/write of flash drives.

    Warning: Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  • Delete all files from SanDisk that accompanies my Cruzer Blade USB Flash Drive (8GB)

    This is why I asked.

    "Is that correct?"

    Yes.

    However, it is possible that on some PC the SecureAccess app can start automatically when you insert the USB key.  But it can be left and the files on the disc normally use.  It is also possible on some PCs that their anti-malware applications may block the access to the USB because it contains files .exe on this subject.  And some of these applications can be configured to not display any windows gains when they block something.

    Didn't, really, it would be a simple Yes or no answer you did?

  • How to recover a W7 OS on the new HARD disk USB flash drive?

    I have my Dell Inspiron 1545 laptop friends. HARD drive have a lot of bad sectors, but it was fun to do:

    • a copy of the image of recovery dell USB flash drive via Dell Backup and Recovery Application
    • a copy of the very important files
    • and a copy of the 2 partitions to each image using Acronis True Image application file:
    1. FAT16 Pri 39, 19 MB FS: FAT16 Partition: 0xde (EISA configuration)
    2. Pri, Act 14.65 GB NTFS RECOVERY

    RECOVERY partition have the same content, such as a usb flash drive with I used to do a recovery Dell image.

    If she buys a new drive HARD this what should I do/use to recover Windows 7 from a USB?

    PS. I have nothing to lose and I try to play with the hard drive has failed.
    First of all I do partition of LBA 0 to 80 GB first where bad sectors and hide this partition.
    Then I do these partitions 2 "dell" and the rest for system files.
    Then I recover these partitions of 2 "dell" using Acronis True Image.
    Then I use a usb flash drive to recover Windows 7, it retrieves for maybe 10 seconds and he said that, please restart.
    When it shows BOOTMGR is missing, press ctrl + alt + delete and now I see only 2 partitions labeled OS ~ 298 GB and RECOVERY ~ 2 GB.

    The best solution is to use ImageX 2.0 to extract file Factory.wim partition RECOVERY or USB flash drive. Just search on google. New installation of operating system is also an option - I know about it. Fortunately, this Dell factory contains no useless software.
