The organization is a large travel company with presence in Europe, the USA, Russia, and Asia Pacific. It provides business travel, outbound tourism, holidays, destination management, and other such services in the travel domain.
It was using a Dell® storage server which comprised of 4*2TB Serial Attached SCSI (SAS) Hard Disk Drives stacked up as a RAID configuration. The server was hosting about 2.5 TB data which largely included crucial business information in the form of accounting data, banking data, images, and various other documents.
One of the disks in the RAID configuration was detected in a failed state which explained the marked degradation in performance of the server; the server read/write speeds had become very slow, with frequent freeze ups.
The Dell PowerEdge RAID Controller (PERC) card attempted rebuilding the failed physical disk by using the pre-configured hot spare, however, the auto-replacement mechanism didn’t succeed for an unaccounted reason.
Subsequently, the storage server administrator decided to take the manual restoration route via the CONTROLLER BIOS Configuration Utility – he replaced the failed disk with a compatible new physical disk of 2 TB capacity; however, the array disks still appeared in a degraded state even after reseating the hot swap, running system diagnostics, etc.
In the meanwhile, due to the continuous usage of this degraded RAID setup with no redundancy, the storage server crashed. Subsequently, the server failed to boot up and displayed the message – “No boot device found”.
Failure of the Dell® storage server turned the complete 2.5 TB data inaccessible, with a high probability of permanent data loss unless the storage could be revived to an accessible state so as to allow data recovery operations.
As the server was used for hosting business-critical assets, its failure affected the overall business, as the stakeholders were unable to access key data points for decision making.
Also, the data on the server largely comprised of banking and accounting information, so its unavailability hampered a majority of business transactions.
Solution — How Stellar® Data Care Experts Rescued the Situation?
After attempting to revive the RAID server by following the standard disk replacement procedures, the IT team of the company decided to engage Stellar® Data Recovery services.
Stellar® - on account of its experienced R&D team, broad expertise in dealing with RAID failure cases, and Class 100 cleanroom infrastructure - was uniquely positioned to deliver the best possible solution for this situation.
Stellar® put together a dedicated team of R&D engineers and data care experts to execute this project. This team began the data recovery task as per the following steps:
The Stellar® data recovery services team successfully recovered the lost data from the Dell® storage server. The entire data recovery project — from job intake and allocation to execution and final recovery — was completed and delivered within the committed time.
The data was recovered with 100% integrity in its original form, as verified and attested by the client. This remarkably fast turnaround and service quality helped the client organization to quickly recover from downtime and resume normal business.
