(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 account multi-tenant structures and cross-cluster access.

● Hardening & Compliance: Enforcing network-level export policies (CIDR-based) and implementing

POSIX-compliant ACLs as well as POSIX group mappings via LDAP/NIS.

● Data Security: Ensuring data-at-rest and data-in-transit encryption in compliance with regulatory standards (GDPR, Export Control) and institutional security policies.

Workload & User Enablement

● Data Movement:



Orchestrating large-scale data transfers using specialized tools (e.g., XCP,

Aspera, Globus).

● Consulting & Optimization: Advising users on I/O-efficient application development and best practices for highly scalable workflows.

Candidate Profile (Skills)
