Scale CWDM networks to 16 wavelengths with up to 8 DWDMwavelengths.

Traffic disruption when installing EDWM When installing EWDM solution, running CWDM trafficneeds to be disconnected in order to connect the trafficto the EDWM filters Traffic will be down on the fiber path until EWDM isproperly installed and running The only way to avoid disruption is to already have abidirectional fiber protected CWDM ring. In this case,upgrade can be implemented on one path first. Whenthe upgrade is complete on the first path, upgrade ofthe protected path can be implemented.

Improving Optical RecoveryPort Track for Resilient SAN Extension Solutions1) MDS Detects Link Failure2) MDS BringsDown Array Port3) Array Retries I/O onAlternate PathOptical/IPNetworkOptical/IPNetwork Arrays recover from a link failure via I/O timeouts; however, this can takeseveral seconds or longer MDS PortTrack addresses this by monitoring the WAN/MAN link and if itdetects a failure, it will bring down the corresponding link connectedto the array The array after detecting a link failure will redirect the I/O to another linkwithout waiting for the I/O to timeout
