I/O performance in need of a fix

What you’ll learn in this tip: The computer industry has overcome a multitude of technological challenges in the past several years. Networking and memory speeds have increased, processors have gotten faster and 10 Gigabit Ethernet (10 GbE) has allowed for a massive increase in bandwidth. However none of these advances will remain beneficial if I/O performance doesn’t improve. Author Arun Taneja outlines the basics of I/O and explains why critical applications are stalled due to I/O performance issues. There are many supposed keys to this decades old issue -- while some turn to Flash, Flash memory or NAND flash memory chips, others look to solid-state and solid-state drive (SSD) controllers.

Taneja Group Research: Deduplication and the Innovation Race -- It Isn't Over

I think it is safe to say that data deduplication technology on the backup side has now gone mainstream. At the enterprise level we estimate that almost all companies have installed some form of data deduplication technology, even if the percentage of data under the jurisdiction of dedupe is closer to 40 percent. In other words, each enterprise has dedupe equipment, but not all backup data is yet being deduped. The reasons vary with each enterprise (importance of application, geographic isolation, limited funding, and so on). When one looks under the covers one finds that some of this deduplication is happening at the source but a large majority at a target, and more specifically, a target appliance.

How Long Are You Willing to Wait to Recover After a Disaster?

With today’s workforce pushing out an increased amount of information, data, and projects, the need for quick recovery from a disaster is imperative.

Scale-out network-attached storage: Options in today’s market

In storage, scale-out systems are becoming a popular option to deal with rapid data growth. File data is growing the fastest, making network-attached storage (NAS) the most popular type of scale-out storage. Clustered NAS systems that fit the “scale-out” tag are targeted at processing heavy applications such as “big data” analytics and large file environments.

AWS Storage Gateway creates ‘co-opetition’ with cloud appliances

Amazon’s AWS Storage Gateway -- the company's entry into the cloud storage gateway market -- has creators of other cloud appliances and potential customers wondering how the move will affect the market, while questioning Amazon’s commitment to adding enterprise features.

Dell launches DR4000, its first backup deduplication appliance

Dell today unveiled the DR4000, the vendor’s first internally developed backup deduplication appliance. Although a late arrival in the disk backup market, Dell is looking to compete with deduplicating backup targets from EMC Data Domain, Quantum and Hewlett-Packard.

Podcast with SearchCloudStorage - Primary Data Storage in the Cloud

Assistant site editor Rachel Kossman sat down with Arun Taneja, founder and consulting analyst at Milford, Mass.-based Taneja Group, to discuss latency, which is the reason behind the majority of this hesitation. Taneja explains to listeners how evolving technologies -- such as inline data deduplication and compression -- have drastically improved the option to place primary data storage in the cloud. He also outlines the benefits of cloud storage gateways, and why they're such a key factor in cloud storage for primary data.
