An EMC NetWorker customer is experiencing poor backup performance. Your analysis determines
that significant host resources are used to manage low-level network handshaking operations
during backup.
Based on EMC recommendations, what can be done to alleviate the handshake issue?
A.
Install 3 TCP offload engine card
B.
Install a second network interface card
C.
Upgrade the LAN
D.
Upgrade the network driver
The answer should be A.
A quote from “https://en.wikipedia.org/wiki/TCP_offload_engine” web page:
“Moving some or all of these functions to dedicated hardware, a TCP offload engine, frees the system’s main CPU for other tasks.”
Therefore by utilizing TCP Offload engine card, handshake process can be offloaded to the card. Backup performance will be increased.
