Broadly following is expected from the candidate
NW design / development, Switch config design, NW driver ( Linux,Chelsio / Broadcom 10G ) & HYDRA internal NW design / development, QX switch, 1G / 10 G NIC support
Expected skill set -
NW technology: LAN, bonding, VLAN, NW protocol(TCP / IP,
UDP ), load balancing algorithm etc
Design of HYDRA internal NW according to new HW ( server, NIC, switch )
Solution for driver problem by having NW driver knowledge
Linux driver source code analysis / modification / maintenance in order to adjust HYDRA spec. Driver implementation to Linux
Vendor negotiation skill with Chelsio / Broadcom about driver
Skill against NW performance trouble (OS / driver / external
NW/ Perf. Analysis / packet dump)
Skill to analyze the intra-system communication.
Holistic understanding on the HYDRA system structure and behavior is also required.
To keep the system communication volume controlled even
incase of a failure, we have a monitoring feature.
For carrying out HW maintenance activities ( replacement of
switch / NIC etc ) without stopping the system, software development and creation of maintenance procedure is required.
