A Good Look at ESX Server I/O

Saturday, November 24, 2007 in Storage by slowe | 6 comments

This article showed up in my RSS feeds; it’s a fairly in-depth look at the ESX Server I/O stack, written by Nick Triantos.  Nick is with Network Appliance; I believe in their Global Services division.  I’ve bookmarked it for a more comprehensive review later, when I can really dedicate myself to the information he’s sharing here.

As an aside, Nick’s blog recently moved; he used to be here, but now can be found here instead.

Great information—thanks, Nick!

    Hi Vincent

    Need some inputs on the following contexts. I’m having HP DL360G5 server with 500 GB of internal harddisk storage space,with VMWare ESX 3.0.1 and have configured 5 VMs. Recently i removed one VM,as it was not required. The situation now is the disk space of the removed VM is not reflecting the free space of data store.

    Need some inputs and your views to solve this issue.

    Thanks

    regards
    vj

    Who’s Vincent? :)

    Are you sure you actually removed it from the datastore? It’s possible to remove it from inventory but not delete the files from disk. Double-click the datastore in VirtualCenter and it will allow you to see the contents of the datastore; from there, you can see if the files are still on the disk.

    Good luck!

    Hi,

    sorry, the name got misspelt.

    please let me know, In which directory the files relate to the deleted VM will reside on the ESX server. after finding, can i go ahead for deletion, will this help in freeing up the space.

    thanks regards,

    If you double-click the datastore in VirtualCenter, you can browse the datastore and find the files for which you are looking. Generally they will be in a directory named after the virtual machine itself.

    Good luck!
