of frame exceeding 1518-byte per Ethernet packet is introduced. The Jambo
frame size can be extended to 9000 byte but also depends on related network
devices.
7. Does NSA-220\NSA-220 PLUS support Jambo frame? What is the benefit
for using Jambo frame?
Yes, NSA-220\NSA-220 PLUS support three kinds of Jambo frame, 4K, 8K and
9K. Once users activate Jambo frame setting in NSA-220\NSA-220 PLUS, then
the transfer rate between NSA and another device will be faster than using normal
traffic size (1518-byte).
8. Does the size of a Jambo frame automatically negotiate with NSA-220?
Since there is no mechanism in negotiating the size of a Jambo frame, NSA-220
cannot dynamically change the size of the Jambo frame once a user sets the size
to be 4K, 8k or 9K. In other words, it is possible to lose data if the sizes of the
jambo frame supported are not the same in clients and NSA-220.
9. How does the file transfer by USB port in NSA-220?
The file transfer is used at FTP mode once users attach their storage in USB port of
NSA-220
10. How does it work after pressing copy button in the front panel of NSA-220?
When pressing the “copy” button, it will initiate the process copying from the one USB
device which is last recognized by NSA220. In other words, users might link two USB
storages in both of USB ports of NSA-220 at the same time. At this moment, if users
press button "COPY", NSA-220 does not copy files into NSA-220 from both of USB
devices together, but only from the USB storage which is the last one recognized by
NSA-220.
