Challenge

Downtime not acceptable during software

upgrades. Legacy/competitive solutions need the

support of adjacent devices during software

upgrade.

Solution

Topology-independent ISSU – Made possible by

QFX5100’s unique software architecture.

Benefits

No traffic loss during upgrades

No port flap during upgrades

Works in any switching architecture

High Threshold

Low Threshold

Microburst

Challenge

Traditional analytics sample at very low frequency

~1-5 seconds. It misses critical events that may

disappear within this time interval. Network is

exposed to hotspots due to events like microbursts.

Solution

Insight Technology – Samples every 8ms

Benefits

Provides real time visibility of network hotspots

(microburst levels)

Enables correlation of historical events and

creates file in multiple formats

Enables admin to circumvent hotspots and

proactive move workloads smartly
