If you already have licenses for 3PAR snapshots (which most customers do) and you are using a Data Protector capacity license (which most recent customers are) then you can do this for free.
(Customers using Data Protector classic license need to pay for a ZDB license but they are surprisingly cheap.)
I've got a customer doing this right now, and they are getting around 250MB/s of backup speed (this is LAN-free, with a relatively old Windows server mounting the snapshot and then writing to a D2D4700 using Catalyst-over-Fibrechannel).
The documentation has a few holes (such as neglecting to mention that you need to use omnidbzdb --ompasswd to tell Data Protector which 3PAR account to use) but overall it seems to be more reliable than traditional VMware snapshots.
Here's the backup flow:
- Prepare all the virtual machines
- Tell VMware to snapshot the VMDK
- Tell the 3PAR to snapshot the LUN the VMDK is on.
- Tell VMware to release the VMDK snapshot
- Mount the LUN snapshot on a spare ESXi server (which can be part of the Vsphere environment, it just has to be explicitly also imported into to the client list)
- Mount the snapshot LUN on a physical host that has access to the 3PAR storage and your backup device
- Tell VMware to make a virtual machine (named after the original virtual machine)
- Attach the VMDK on that snapshot LUN to the new virtual machine
- Backup the virtual machines
- Tell the ESXi server to snapshot the VMDK (dumb, I know)
- The backup host reads from the LUN, and writes to the StoreOnce
- Unmount the LUN from the backup host
- Tell the ESXi server to release the VMDK snapshot
- Clean up each virtual machine
- Destroy the virtual machines on the ESXi server.
- Destroy the LUN snapshot on the 3PAR
If this is something you want to do -- and it really does work very well -- let me know and I can organise licenses and/or implementation for you.

Great feature, thanks for mentioning!ReplyDelete
