Access "Solid-state storage finds its niche"

Published: 01 Nov 2012

  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 technology has been around for ... Access >>>

    • 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.
