Job DescriptionQualification & Experience:
n8+ years of working experience in IT working on Linux environments (RHEL) with development
nexperience. ● Solid Linux/RedHat system administration skills for Installing, managing Scientific
nComputing applications and Performance Analysis and debugging real time application execution.
nStorage Infrastructure & Data Lifecycle Management
n● Design & Engineering: Architectural planning, deployment, and administration of parallel file
nsystems (e.g., Lustre, IBM Spectrum Scale, BeeGFS) and scalable object storage solutions.
n● Performance Engineering: Continuous monitoring of storage I/O performance; identification and
nmitigation of I/O bottlenecks to ensure throughput requirements for compute workloads are met.
n● Data Lifecycle Strategy: Preparing for the future implementation of tiered storage concepts
n(HSM/ILM) to enable automated data migration across different performance tiers (hot-to-cold
narchiving).
nNetwork Architecture & Troubleshooting
n● Advanced Diagnostics:



Analyzing complex interdependencies between storage backends, file
nsystems, and fabric architectures.
n● Protocol Analysis: Utilizing deep packet inspection tools (e.g., tcpdump, Wireshark) and
nperformance profiling suites (e.g., fio, perf, iostat) to isolate packet loss, latency jitter, or metadata
nlock contention.
n● Interconnect Optimization: Performance tuning of low-latency network configurations
n(InfiniBand/Ethernet) with a specific focus on RDMA protocols (RoCE/iWARP).
nAccess Control, Security & Compliance
n● Identity & Access Governance: Managing NFS (v3/v4) and SMB/CIFS exports, taking into account
nmulti-tenant structures and cross-cluster access.
n● Hardening & Compliance: Enforcing network-level export policies (CIDR-based) and implementing
nPOSIX-compliant ACLs as well as POSIX group mappings via LDAP/NIS.
n● Data Security: Ensuring data-at-rest and data-in-transit encryption in compliance with regulatory
nstand
