I need some explanation about this one
A customer wants to use a VNX system at a disaster recovery site. The system will be used exclusively as a secondary MirrorView/A system and is capable of performing 90,000 LUN IOPs in this role. The primary system is also a VNX.
If the total primary image workload consists of 4 KiB random I/Os with a read/write ratio of 4:1, what is the maximum bandwidth required for the link between the VNX systems?
