QLogic Introduces Non-Disruptive Code Load and Activation (NDCLA) for SANbox2™ Fabric Switches

Key Milestone for SAN Administrators That Want Director-Class Features at Fabric Switch Prices

ALISO VIEJO, Calif., June 16, 2003 - QLogic Corp. (Nasdaq:QLGC), the company that powers storage area networks (SANs), today announced its entire line of SANbox2 2Gb switches now feature Non-Disruptive Code Load and Activation (NDCLA), a director-class feature that provides SAN administrators with a non disruptive way of performing the frequent switch code loads required to maintain interoperability when new equipment is added to a SAN. Included with each SANbox2 switch at no-charge, NDCLA reduces scheduled hardware outages for firmware upgrades, resulting in improved ROI and better use of IT resources.

Perform Switch Upgrades without Disrupting Data Traffic or Devices
Unlike competitive NDCLA offerings, the SANbox2 switch family activates new code versions without causing any fabric disruptions which means:

  • No interruptions or delays to live data traffic.
  • No re-initialization of attached devices due to additional Registered State Change Notification (RSCN) traffic.

"The line between director class-products and edge switches is beginning to blur, which is good news for small and medium enterprise customers," said Frank Berry, vice president of marketing, QLogic Corp. "Not long ago, a feature like NDCLA would have been exclusive to expensive directors. Now we can offer it with all of our 2Gb edge switches along with other director-class features like our SANbox2-64's full crossbar, non-blocking architecture."

The NDCLA feature will be available this quarter, at no additional charge, for all products in the SANbox2 family.
