He used encryption on this hard drive to make his data safe.
Dennis Hartmann on Cisco Unified Communications:Cisco QoS: Link Fragmentation and Interleaving The goal of LFI is to lower serialization delay on slow speed links. Serialization delay is the amount of time it takes a router to serialize a packet onto a WAN link. The goal of LFI is to ensure serialization delay never takes more than 10ms.
Kamal Vyas: Next Gen Data Center:Fabric Extender - Extended Virtual Chassis ... very FEXY! When looking at end-to-end Nexus DC design and Nexus 7K vPC , one of the prominent CPOC test components is FEX (Fabric Extender) module. The best way to describe FEX would be a (remote) line card hanging off a Cisco Nexus 5000 switch. (Cisco Subnet extends a welcome to Kamal Vyas as our newest blogger. Vyas is a lead Data Center Network Design Engineer at a $3.5 billion high-tech company.)
