Designing Backup to replace Primary Storage

blueprint

Good post by George Crump (thank you)

Users and application owners expect that the systems they use will never go down, and if they do they will be returned to operation quickly with little data loss. In our article “Designing Primary Storage to Ease the Backup Burden” we discussed how to architect a primary storage infrastructure that is able to help meet these challenges. We call this design Protected Primary Storage. But this design can be expensive, especially if it is applied to every application in the data center.

Backup is not Archive

Good post by Joseph Ortiz (thank you)

In order to protect their data while dealing with explosive data growth, many organizations have started backing up their data to the cloud in an effort to reduce their storage and data center costs as well as obtaining data redundancy without the need to maintain a separate physical DR site. Many also mistakenly believe that these additional backup copies qualify as archive copies. Unfortunately, they do not.

Too much of a Good Thing? IBM Buys Cleversafe

Good post by George Crump (thank you)

The industry is mesmerized by all things flash and sometimes forgets that IT professionals have other challenges to face than just meeting the performance demands of the modern data center. One of those is dealing with unstructured data. Data centers are drowning in data and are looking for solutions that can cost-effectively and reliably, store all of it. Despite its slower than expected adoption rate, object storage remains an ideal way to store and retain all the data that organizations capture. To that end, IBM has purchased one of the top companies in the object storage market; Cleversafe.

Unstructured Data is distracting Backup Administrators

Post by George Crump (thank you)

File based data accounts for more than 80 percent of capacity demand and backup administrators spend most of their time protecting this unstructured data. But the remaining set, structured data, will cause the organization the most harm if it is not recoverable. This data (databases, VM Images) requires special backups and fast recoveries. The key to protecting the organization from disaster is to eliminate the unstructured data protection problem. If backup administrators could focus 100% of their time on 20% of their problem, then organizations would be in a much better position to protect themselves from a disaster.

Redefining Storage Operations with VMware Virtual SAN

Post by Rafael Kabesa (thank you)

Virtual Machines much like physical ones require storage. Storage, on all its forms, is exponentially growing in recent years – almost doubling every other year. With the explosion of storage demands, IT managers are challenged to deliver the same service levels to virtual environments as they do with physical ones.

The Bleak Future of NAND Flash Memory

Good Paper by Laura M. Grupp, John D. Davis and Steven Swanson (thank you)

In recent years, flash-based SSDs have grown enor- mously both in capacity and popularity. In high- performance enterprise storage applications, accelerating adoption of SSDs is predicated on the ability of manufacturers to deliver performance that far exceeds disks while closing the gap in cost per gigabyte. However, while flash density continues to improve, other metrics such as a reliability, endurance, and performance are all declining. As a result, building larger-capacity flash- based SSDs that are reliable enough to be useful in enterprise settings and high-performance enough to justify their cost will become challenging.

Why IBM Will Win the War With Amazon Web Services

Post by Rob Enderle (thank you)

Amazon dominates the cloud, but IBM, strengthened by its SoftLayer acquisition, has unleashed a marketing campaign that fires on all cylinders. Whether IBM’s cloud is, in fact, better may matter less than Amazon’s ability to challenge a company that’s made many competitors crumble over the past 102 years.

Is it Time to Upgrade Your Storage Evaluation Process?

Good post by George Crump (thank you)

In the modern data center, storage system upgrades are rarely caused by a storage system running out of capacity; rather, it more often occurs due to an unanticipated lack of performance or exorbitant maintenance prices. In fact, performance related upgrades can occur at any time, often well before the current storage system was due to be refreshed and more importantly before the evaluation process had predicted a refresh would be needed.
