DELL PowerVault MD3800i Complete Recovery
September ended with successful data recovery from Dell PowerVault MD3800i enterprise-level storage.
The raw capacity of the device was 110TB, and it is a massive amount of space. Eleven pieces of 10 TB SAS hard drives worked together as RAID 6 volume to have redundancy and more space. The RAID volume was used as a VMWare datastore storing critical virtual machines.
The volume damaged due to the consecutive failure of three hard drives. The objective of the recovery was not just the recovery of the data stored in the storage. All the virtual machines should be up and running again. The whole infrastructure collapsed, and the business suffered loss from this incident.
It took ten days to recover and copy back all virtual machines back to the storage. We handed over the result to the customer in his office and further recommendations made to prevent future data loss scenarios.
