Hot Code Load (HCL), also known as Non-Disruptive Firmware Upgrades, have been available for Fibre Channel platforms for a long time, but not for the extension platforms. With the recently announced Brocade 7840 Extension Switch, HCL is now available for extension switches. This feature is critical for replication in mission critical environments where companies cannot afford to take their infrastructure down while they upgrade. With the higher data rates everyone is dealing with, even a short window of disruption can cause you to fall behind and open yourself up for risk.
Truls Myklebust, director of product management, and Dennis Makishima, VP software engineering, discuss the technical details of the HCL for Brocade extension solutions, including:
- How the feature works
- Why it is important
- Design considerations for how to take full advantage of the capability
