Using parity for redundancy of managed LRS disks?


  • Hello,

    I created a VM, added managed LRS disks and created a parity virtual disk for redundancy, but do I really want to lose in storage size by adding redundancy through parity? Are not LRS disk already redundant?

  • That's correct. You don't need to choose the parity option since Azure Storage maintains three copies of the underlying blobs. If your VM is running on Windows Server 2012 (or 2012 R2) you can leverage the 'Storage Spaces' feature that lets you virtualize storage by grouping industry-standard disks into storage pools, and then creating virtual disks called storage spaces from the available capacity in the storage pools.
