Solid-state storage finds its niche

  Still extremely expensive vs. traditional media, solid-state disks can make a convincing economical case for some applications requiring very high IOPS. With the cost of hard disk storage falling to $0.50 per gigabyte or less, the International Securities Exchange (ISE) in New York City decided to buy a 128GB storage system that lists for approximately $85,000 or $664/GB. While that sounds shocking, the company considers it a smart move. "We have a very latency-sensitive application [that handles stock trading], and the storage gives us a distinct competitive advantage," says John Ryan, ISE's technology architecture officer. The solid-state disk (SSD) system from Texas Memory Systems Inc. handles reads and writes in 0.02 milliseconds (20 microseconds), which is orders of magnitude better than the fastest hard disk drives (HDDs). The SSD system that ISE selected is based on double data rate (DDR) DRAM technology and comes integrated with battery backup, a Fibre Channel (FC) interface and conventional hard drives. This SSD ...

  • Solid-state storage finds its niche

    by  Alan Radding

    Storage managers facing critical storage performance problems and needing maximum IOPS have found a feasible option in solid-state disk. Solid-state storage is fast, cool and it barely sips power, but it's still far more expensive than traditional media.

  • Where encryption fits best

    by  Jerome Wendt

    Everybody knows they should encrypt tapes that go offsite, but many are still on the fence about where encryption should occur in their storage environments. There are a number of options, ranging from using your backup app's encryption capabilities to installing a purpose-built encryption appliance. We weigh the pros and cons of the available alternatives so that you can decide which approach best suits your shop.

  • Hot Spots: Web 2.0 storage: Challenges and choices

    by  Bob Laliberte

    Web 2.0 tools and strategies hold many potential benefits for businesses that deploy them, but their requirements for rapidly scalable storage and access, as well as persistent data, pose significant challenges for the IT staffs that need to build and manage the infrastructure.

  • Best Practices: Tackling data migration

    Data center projects often involve migrating data, which is frequently a painful process that can lead to unplanned downtime and outages. It's time to adopt consistent, repeatable migration practices. Selecting the right approach is highly dependent on infrastructure limitations, data and platform types, time constraints and staff capabilities.

  • Storage Bin 2.0: Virtually changing everything

    Server virtualization drives storage growth and dramatically drives the proliferation of storage networking. This is enabling the re-invention of how we manage, protect, store and access information.
