• Oversee hardware upgrades and replacements for HPC, Kubernetes, Greenplum, Impala, and GPU server systems to improve compute and graphics processing capability.
• Use Impala Insight IQ and NetApp tools to diagnose and address throughput, latency, and capacity-related issues.
• Leverage OneFS and ONTAP troubleshooting tools, logs, and error signals to identify and resolve system errors and hardware malfunctions.
• Troubleshoot performance bottlenecks and system failures across HPC, Kubernetes, Greenplum, GPU servers, Impala, and NetApp environments.
• Implement continuous monitoring using Isilon OneFS event logs, NetApp ONTAP tooling, SNMP alerts, and Grafana to detect anomalies early.
• Schedule maintenance through Isilon and NetApp software suites to support optimal storage performance and system longevity.
• Maintain server environments across HPC, Kubernetes, Greenplum, GPU, Impala, and NetApp, including updates and routine system health checks.
• Apply Impala patches and NetApp patches and firmware updates to nodes and system software to keep components secure and current.
• Validate software changes in a sandbox environment before rolling updates across the cluster.
• Plan and manage patch installations across HPC, Kubernetes, Greenplum, GPU servers, Impala, and NetApp to preserve software integrity and security posture.
• Provide storage optimization guidance for Isilon and NetApp, including data migration, system expansion, and configuration tuning.
• Support optimization of HPC, Kubernetes, Greenplum, and GPU server configurations to improve computational resources and data processing workflows.
• Assist with the design, configuration, and optimization of NetApp storage architectures for efficient data management.
• Coordinate phased decommissioning of aging Isilon and NetApp hardware in alignment with environmental standards and security protocols.
• Arrange replacement of EOL hardware for HPC, Kubernetes, Greenplum, GPU servers, Isilon, and NetApp to prevent performance degradation.
• Ensure Impala, NetApp, HPC, Kubernetes, Greenplum, and GPU storage solutions are integrated and compatible with the broader IT infrastructure.
• Develop strategies for integrating storage and processing technologies to maximize performance and resource utilization.
• Maintain detailed documentation for system configurations, upgrades, and troubleshooting actions to support repeatability and team onboarding.
• Conduct training sessions or create guides so internal teams can share knowledge about system operations and best practices.
• Plan and test disaster recovery procedures for Impala, NetApp, and HPC/Kubernetes/Greenplum/GPU servers to support data availability and business continuity.
• Ensure backup and recovery processes are implemented and regularly tested to reduce data loss risk.
• Develop capacity planning approaches to scale storage and compute resources based on performance trends and business needs.
• Create and maintain automation scripts for monitoring, data migration, and maintenance to improve efficiency and reduce manual errors.
• Ensure compliance with organizational security standards and relevant regulations during maintenance, upgrades, and troubleshooting.
• Coordinate with security teams on best practices and hardening measures for Isilon, NetApp, HPC, Kubernetes, Greenplum, and GPU servers.
• Support data center activities including racking and initial installation of servers and storage equipment, with attention to cabling, power connections, and networking setup.
