Recovery of a NAS Server is a Highly Complex Endeavor

So, you think recovering a NAS server is an easy task?  Well, think again.  NAS servers may be a lower-cost RAID based solution aimed at small to medium sized companies, but technically, they are as complex and difficult to recover from as some of the high-end storage systems.  Since most NAS systems manufactured today have advanced features similar to those of high-end SANs, like deduplication, virtualization support, and iSCSI targeting, …Read More

6 Tips to Prevent Data Loss in Your RAID Based Storage Array

Since the introduction of the concept of RAID, it has redefined how storage systems manage and store data. The basic concept of this technology is actually quite simple: A RAID array is a configuration of many different physical hard disks that together create the used RAID architecture (RAID level 0, 1, 5 etc.).  The RAID architecture then distributes data over all disks because the RAID is regarded as one single …Read More

How does RAID storage work? – Part 2

In part 1 of this article, we explained the basic idea of RAID, as well as the most commonly used terms when talking about this type of storage. In this second part, we’ll take a look at what RAID levels are and explore how some of the traditional level configurations work. We’ll also find out what challenges RAID storage can bring if data recovery services are required. Let’s take a …Read More

How does RAID storage work? Part 1

Redundant Array of Independent (originally Inexpensive) Disks (RAID) is a term used for computer data storage systems that spread and/or replicate data across multiple drives. RAID technology has revolutionized enterprise data storage and was designed with two key goals:  increase data reliability and increase I/O (input/output) performance. Unfortunately though, RAID storage isn’t a perfect technology and as a result data loss can still occur when using these systems. In this …Read More
