  • Slimmer storage: How data reduction systems work

    Although it’s become a staple of backup systems, data reduction is now just starting to show up more and more in primary storage systems. In the October 2012 cover story of Storage magazine, Chris Evans takes a look at the state of the data reduction... 

  • Solid-state adds VROOM to virtual desktops

    Virtualized desktops can cut administrative and maintenance chores down to size, but some solid-state help will likely be needed on the storage side. 

  • Primary storage dishes up dedupe

    Read the April 2010 edition of Storage magazine for details on how and where deduplication and data reduction technologies are being used in primary storage – beyond previous advances in backup systems. 

  • Enterprise data storage capacity planning guide

    Maximizing your enterprise data storage capacity is more important than ever before. With the majority of storage budgets unable to keep pace with data growth rates, most storage administrators need to find ways to reduce capital and operating expens... 

  • How vSphere is easing storage burdens of server virtualization

    In the January 2010 issue of Storage magazine online, we turn our attention to vSphere. This VMware release included many features designed to ease the storage burdens that server virtualization can cause. Our cover story tells you how each feature w... 

  • Email storage lessons learned from Citigroup

    Citigroup's Shaun Mahoney must keep 235,000 users' emails for compliance purposes, and that's just one application. Also learn what virtual servers mean for storage, and get 10 steps for better backup. 

  • volume manager

    A volume manager is software within an operating system (OS) that controls capacity allocation on arrays. 

  • helium hard drive

    A helium drive is a hard disk that exploits the characteristic lightness of that gas to increase the medium’s potential speed and storage density. Potential speed and density are increased because helium, which is less dense than air, creates less d... 

  • erasure coding

    Erasure coding (EC) is a method of data protection in which data is broken into fragments, expanded and encoded with redundant data pieces, and stored across a set of different locations, such as disks, storage nodes or geographic locations. 

  • data reduction in primary storage (DRIPS)

    Data reduction in primary storage (DRIPS) is the application of capacity optimization techniques like deduplication and compression, which are more typically used for backup, to a computer's primary storage. 

  • Fast Guide to RAM

    Cheat sheet quick look-up for different types of RAM. 

  • automated storage tiering (AST)

    Automated storage tiering (AST) is a storage software management feature that dynamically moves information between different disk types and RAID levels to meet space, performance and cost requirements. 

  • nano-storage

    Nano-storage is a nanotechnology approach to storage that seeks to radically increase storage capacities through a variety of technologies, and, ultimately, to replace current storage media with extremely high-density media and devices.
