Sans Digital – MN4L+ Admin Guide

NOTE:
• If primary NAS had data stored before configuring SFM, it will immediately start to copy its data to the secondary NAS right after
configuring SFM. Depending on the size and type of file(s) on the primary NAS, copy process time will vary.
• When the former primary NAS (now secondary server) is re-deployed, data copy from former secondary NAS (now primary NAS)
to former primary NAS (now secondary NAS) will take place immediately.
• Since NAS-to-NAS data mirroring involves multiple writes of same data, overall throughput of the MN4L+ will be reduced.
Performance varies on usage, type of data being transmitted, and workload that Mn4L+ is subjected to. Anyway, it is a trade-off
between performance or redundancy.
