    Smarter storage from metadata, object stores

    One of the distinguishing features of object storage systems is their ability to package more metadata with each object they store. That metadata could be used to restrict access, define a file's lifecycle and its ultimate disposition. Other storage products are emerging that can do the same or similar type of data classification. This allows data management tasks to be automated via policies set by IT, thus creating smarter storage systems.

    Enterprise file sync-and-share use has taken off in many organizations, but consumer file sync-and-share use can leave corporate data unprotected. In-house EFSS can help guard against data loss by giving IT oversight and control.

    Today, organizations face a wide array of storage challenges. Luckily, there are myriad training and certification opportunities for IT pros looking to bolster their knowledge of the storage technologies.

    Big data workloads live on-premises

    Seven years after its birth, the frenzy around cloud is beginning to subside. IT organizations have embraced public cloud for some workloads, and built private clouds for others.

    IT is having productive discussions about which applications to leave where they are, and which applications to re-platform. They're considering the pros and cons of renting shared infrastructure rather than buying dedicated on-premises resources.

    You may not get the raw performance from a virtualized cloud instance that you could from dedicated bare-metal hardware -- you need to weigh that against the cost of hiring data center operations staff.

    Meanwhile, the hype around big data and social media has just begun. The technology for doing this kind of analytics exists today. You can build a Hadoop-based repository to store the untold amounts of raw data that can later be used to discover unimagined relationships and patterns. It all sounds very promising, but for now, the jury's still out about the value of these initiatives.

  • The 4-1-1 on DR testing technologies and best practices

    Experts agree that testing is one of the most important aspects of disaster recovery planning. It is the only way to ensure that you are able to bring systems back online to meet recovery time objectives and recovery point objectives.

    But, historically, IT teams have struggled with DR testing because it can be disruptive to employees that need access to essential applications. That is changing. Advancements in server virtualization, cloud computing and DR software have made DR testing more practical and much more affordable. This Drill Down on DR testing offers in-depth information on these technologies, DR testing best practices and advice on how to create DR test scenarios for your environment. If you are planning a DR test -- or you haven't run a DR test in a while -- you need to read this guide.

  • Becoming familiar with VM-aware storage

    As with any product still in its infancy, an exact definition for virtual machine-aware storage can be difficult to nail down. In simple terms, VM-aware storage is an appliance that vendors build specifically with virtual machines in mind in order to cut back on some of the most pertinent issues in virtual environments: complexity, difficult management and lagging performance.

    Using VM-aware storage typically means there's no need to configure logical unit numbers and volumes, and because VMs are directly associated with the storage they reside on, priority can be given to more demanding apps and VMs can be granularly managed. This guide will walk you through what products classify as VM-aware storage, how they are implemented in virtual environments and what benefits they can bring to storage and virtualization administrators so you can make an informed decision about whether they're the right choice.

  • Six hot data storage trends for 2015

    For 12 years, Storage magazine has presented its roster of new data storage trends that are ready to have an impact in data centers. We’ll tell you why VMware VVOLs, all-flash arrays, cloud disaster recovery, flash caching, server SANs and hybrid arrays should be on your short list for storage technology refreshes.

    Admins struggled with backing up virtual machines (VMs), until vendors responded with updated suites and new backup apps especially for VMs. But there were more basic issues with supporting virtual environments with traditional SAN and NAS systems. A handful of startups stepped up with arrays that shed the paradigms of the past in favor of a hypervisor-centric approach. Find out what life after LUNs is all about.
