Gen 5 Fibre Channel Helps Close the Storage Migration Window
A process known as Live Storage Migration allows for a non-disruptive migration of running VM disk files
between two different physical storage devices. This process allows for the VM to remain running with no
need to take its workload offline to move the VM’s files to a different physical storage device. Additional use
cases for Live Storage Migration include migration of data to new storage arrays or larger capacity, better
performing LUNs. NPIV zoning and LUN masking must be properly configured to ensure the VM and host
server continue to have access to the storage after the migration is completed. Live Storage Migration across
a Gen 5 Fibre Channel link can finish in half the time it takes with an 8Gb Fibre Channel link. All paths related
to Live Storage Migration should be supported by high-performance networks to reduce the time it takes to
evacuate storage safely to a new destination and resume normal operations. Additionally, 10GbE links can
replace 1GbE links to ensure proper bandwidth exists for Live Storage Migration in Ethernet environments.
Live Storage Migration
A single-port QLE2670 Gen 5 Fibre Channel Host Bus Adapter can double throughput for a live storage migration.
Storage Live Migration at Gen 5
This bandwidth-intensive operation now enables VMs and
associated VHDX files to be migrated between clusters that
do not have a common set of storage.
