(HSM/ILM)



to enable automated data migration across different performance tiers (hot-to-cold
archiving).
Network Architecture & Troubleshooting
● Advanced Diagnostics: Analyzing complex interdependencies between storage backends, file
systems, and fabric architectures.
● Protocol Analysis: Utilizing deep packet inspection tools (e.g., tcpdump, Wireshark) and
performance profiling suites (e.g., fio, perf, iostat) to isolate packet loss, latency jitter, or metadata
lock contention.
● Interconnect Optimization: Performance tuning of low-latency network configurations
(InfiniBand/Ethernet) with a specific focus on RDMA protocols (RoCE/iWARP).
Access Control, Security & Compliance
● Identity & Access Governance: Managing NFS (v3/v4) and SMB/CIFS exports, taking into
