Don't Write Off Disk

Quantum (NYSE: QTM) is a manufacturer of tape drive, tape automation and disk-based data de-duplication backup, recovery and de-duplication storage provider. The company has a current market cap of $309.68 million.

Virtualisation is quickly changing the way businesses operate their IT departments, with many companies already jumping on the virtual bandwagon. The high adoption rate only emphasises the ability to combine capabilities and streamline processes. However, the benefits of physical appliances have been widely known for some time. As new technologies are implemented, it's important to look closely at the advantages of traditional storage such as disk. And contrary to what you may have heard, disk is anything but dead.

This isn't the view of a company wedded to tape. With the use of object storage disk for retaining all unstructured archived data, we've already seen a new lease of life whereby corporations are able to store and access everything in ways which were previously not possible. And by moving all unstructured archived content to a disk-based object storage platform, you accomplish several things at once. First off, you immediately reduce the burden on your primary storage resources, as well as improving the performance of your backup operation. At the same time, you're able to free up network bandwidth that is involved in your backup processes.

What strengthens the case to opt for disk now more than ever before is down to two key ingredients. First, today's next-generation object storage technology includes some level of forward-error-correction technology that enables objects to be spread across components to accomplish durability much like what RAID technology does for drives within an enclosure. However, some implementations of object storage can go way beyond spreading data across drives in an enclosure. Data can now be spread across enclosures and even across geographies, and in doing so the user can ensure extremely durable archive data protection - protection against component failure, against enclosure failure, and even against site disaster.

Previously, when users thought about doing this, they'd think about moving archive data from primary storage to less expensive disk or maybe even tape. But they'd still insist on at least two copies - and in many cases three - to ensure their archive data didn't disappear in the event of failure or disaster. Now a single instance of data on object storage technology provides better durability than RAID and disaster resilience as good as tape, so users have the best of both worlds with a single instance on a single technology - object storage.
