RAID Data Recovery For Newbies
Long seen as a robust, solid storage platform, the RAID server has demonstrated the kind of steadiness that has many administrators virtually ignorant of RAID data recovery as an option. Certainly the "R" of RAID helps with this idea, as "redundancy" is one of the crucial reasons why RAID is the sole form of storage trusted for such mission-critical products as Oracle databases, Exchange servers and high end web servers. For many, this is the best solution: providing superior data access speed with the peace of mind of surviving a single hard drive loss without any real dire effects. But from time to time, despite its intended invincibility, RAID recovery is necessary.
Understanding the frailties of the RAID storage application is the key to any smart IT administrator's knowledgebase. We are talking about, after all, the storage industry's top performing solution since it first debuted back in the 1980s. The drives have gotten cheaper and larger, but essentially, we still have the same ideas in place. And therein lies the issue. RAID arrays are still based on the ancient hard drive form factor, one in which data is stored on platters and retrieved by the same heads (albeit better quality) within the single hard disks. The fault of hard disks, meanwhile, remains the fact that we are still relying on the same mechanical disks that are subject to the same mechanical failure. And when the drives go down, the array goes down with them.
So what then is a reasonable administrator to do? Preparation is always the best concept, obviously, and is not as difficult as it may seem. Consider these concepts when planning for RAID array failure:So is this all a "destined to fail scenario"? Well, not quite. Being proactive remains the IT administrator's greatest weapon against RAID breakdown, and the following hints may help broaden this pro-activeness:
Prepare An Inventory - If you are in control of your company's IT assets, or have responsibility over some of them, make sure you know exactly what lies within your duties. This means everything, from simple user laptops to major mainframe systems. Don't get caught unaware when RAID or hard drive failure rears its ugly head.
Gathering The Details On Your Systems - Once you've made a list of what Information Technology solutions you're responsible for, it is your duty to create a knowledgebase that will be your go-to in the event of an emergency. To begin, analyze your list of systems, and prioritize the key ones, such as machines that use mission-critical technologies such as Exchange servers or Oracle databases. Set about gathering all important manuals, manufacturer support site addresses (including that for RAID controller cards and specialized components), and good product forums. Better to find and collect all of this information now, as opposed to when things have gone south.
RAID Recovery At Your Service - Even if you don't have a case where you've lost a drive or a server has melted down, any wise IT administrator knows that knowing an expert is the best case scenario. Do you have someone you can call when your system is going haywire? Collect a shortlist of potential vendors now, and also investigate specialized services, such as 24 hour RAID recovery, which will be a safety net if the organization is stalled because of a serious tech emergency. Contact some companies now and mimic an emergency if necessary. How do they react?
Despite what the huge majority of hardware vendors may claim about RAID and other storage applications, none of them are completely invulnerable. Understanding now what to do when you need RAID data recovery is a best practices option, and will make things easier in the event of a disaster.
