Failed Raid Controller

Behavior of RAID controller

Our experts understand the behaviour of RAID controllers based on the parity course followed. This understanding comes in handy when our technicians perform reverse engineering to restore your data. You can reach out to our RAID Data Recovery experts for a free consultation.

Raid Striping

RAID striping & mirroring

RAID configurations employ striping, mirroring, parity, or double parity methods to create reliable large-scale data stores. The data recovery experts at Stellar® are adept at these concepts. This is crucial when restoring large volumes of data from RAID servers.

CASE Study

India’s First RAID Z Data Recovery

Raid Z data recovery extremely. Nobody had accomplished this in India. Our team succeeded in recovering 12 TB of mission-critical business data from a failed RAID Z-configured Dell® server

Stellar RAID Recovery

India’s First Successful Data Recovery From RAID Z Server

RAID Z integrated with the ZPS file system is better than the traditional RAID server. However, RAID Z is more complex than any other RAID configuration, in terms of disk space usage, average file size, and the OS. So when you lose data accidentally, recovery also becomes more complex. 

A leading Indian healthcare enterprise client trusted us with data recovery for their Dell PowerEdge R710 RAID Z server. The server and ZFS volume, which hosted customers’ sensitive data, became inaccessible.

What are the common causes of RAID failure?

RAID may fail due to the following reasons:

  1. Virus/malware attack
  2. Physical failure of RAID drives
  3. Issues with RAID Controller
  4. Sudden power outage
  5. Software errors
Can RAID Reconstructor work without a drive in Raid 0 array?

No, RAID 0 is non-redundant and does not allow the loss of a drive in the array. You would lose data, if a single drive fails.

Which RAID is best for data protection?

RAID 5 is considered to be the best server format for disk arrangement. It is the most used one by businesses and enterprises. RAID 5 performs better than mirroring and also has better fault tolerance. 

In terms of speed and performance, RAID 0 is considered to be the best. 

How often do RAID drives fail?

On average, a RAID server has a 2.5% failure rate every year of its operations. Hardware issues, like Rotational Vibration, are hard to avoid. This is why it’s important to know a professional RAID data recovery service on whom you can rely on. 

How should I recover a failed RAID array?

The safest way that assures maximum data recovery is to entrust the recovery to professionals. RAID systems usually require technical skills to fix that not all IT executives have. 

What is the RAID recovery process?

At Stellar, we follow a 4-step RAID recovery process. First, you can get a free consultation from our RAID recovery consultant. Then. we analyse the issue and give you a quote. Then we conduct RAID data recovery in our high-tech labs. Finally, we verify the recovered data for correctness and accessibility. 

Can you recover data from RAID 0?

RAID 0 arrays are non-redundant. So if the information from one file is lost, it’s non-recoverable. If the data is on another member disk, you can attempt recovery. But it’s successful only if the files are of a specific size.

Probably the best data recovery company and awesome.
Superb service recovered all our data from a NAS box. We were worried about the data loss but Steller helped us and recovered our all data with 100% data integrity at a very very good price. The Stellar team is very honest unlike other companies and have a fixed price list. Extremely helpful and they are not trying to sell you anything just genuinely trying to help you recover data. I would be very careful with other companies as there are a lot of data scam companies. Truly Stellar saved some very very important data and to us, they are the best!!! Keep up the good work.
