TSX-EMEA: VCB today and tommorow

Watch out that the LUN numbers presented to the VCB proxy match the ESX hosts LUN numbers. Additionally, VCB does not currently support multiple fibre-channel cards for multipathing to the LUN.

Presenter: Andy Tucker, Principle Engineer, VMware.

Nothing shockingly new to report here – but to watch out that the LUN numbers presented to the VCB proxy must match the ESX hosts LUN numbers. Additionally, VCB does not currently support multiple fibre-channel cards for multipathing to the LUN.

Andy did outline some new features planned for VCB including:

  • Solve the LUN numbering problem by using the VMFS UUID values held in the metadata
  • Multipaths to be supported
  • Using VMware Convertor assist moving files from the VCB proxy to the ESX host
  • Incremental Backups
  • Better quiescing of the VM during the snapshot process

Later this week I did a lab on VCB. One neat trick was that the lab guys had set up the VCB proxy to also be a NAS/NFS to the ESX host. So we restored the backup to the VCB proxy into a folder that had been set a mount point to the ESX host. This made the network restore process with vcbrestore much easier to achieve.
