DELL RACK ADMINISTRATOR

DELL RACK ADMINISTRATOR — STORAGE, BACKUP & OT NETWORK INFRASTRUCTURE Location: NYC area

ABOUT THE ROLE

Our IRS/SCADA Modernization practice designs, deploys, and sustains the control system infrastructure behind water treatment, wastewater, power distribution, and industrial process environments. The Dell Rack Administrator owns the physical and logical infrastructure layer that SCADA runs on: Dell PowerEdge server racks, Dell SAN storage, Dell EMC Data Domain backup appliances, and the Cisco and Arista switching fabric that ties control system nodes together. This is not a conventional data center role. You will be equally comfortable in an enterprise rack room and on a plant floor, and you understand how PLC, DCS, and HMI traffic behaves across an OT network — deterministic timing, VLAN and IDMZ segmentation, and the operational consequence of an unplanned reboot on a live process.

KEY RESPONSIBILITIES

Server & Rack Infrastructure Specify, stage, rack, cable, power, label, and commission Dell PowerEdge servers for SCADA, historian, HMI, and engineering workstation nodes Deploy and administer VMware vSphere/ESXi hosts supporting virtualized control system infrastructure Maintain iDRAC, OpenManage, and firmware baselines under change control, coordinating outage windows with plant operations Storage & Backup Administer Dell storage platforms (PowerStore, Unity, SC Series, PowerVault) — provisioning, LUN/volume management, replication, snapshots, capacity planning Configure and troubleshoot Fibre Channel and iSCSI fabrics, zoning, and multipathing Own Dell EMC Data Domain administration — deduplication, replication, retention lock, DD Boost Design, execute, and test backup and restoration for SCADA servers, historian databases, PLC/DCS program archives, and HMI application files Networking — Enterprise and OT Configure and troubleshoot Cisco (Catalyst, Nexus, IE industrial series) and Arista (EOS) switches — VLANs, trunking, LACP, spanning tree, QoS, ACLs, routing Implement segmented control system networks aligned to the Purdue Model / ISA-95, including IDMZ design and conduit/zone documentation consistent with ISA/IEC 62443 Support networks carrying Modbus TCP, EtherNet/IP, PROFINET, DNP3, IEC 61850, and OPC UA traffic — multicast/IGMP handling, latency constraints, ring and redundancy topologies Configure and maintain industrial gateway hardware (Moxa, Red Lion) and serial device servers Security & Documentation Apply hardening baselines (DISA STIG, CIS Benchmarks, or client standard) Produce rack elevations, network diagrams, IP schedules, cable schedules, and as-built documentation to submittal quality Support commissioning, FAT/SAT, cutovers, and post-cutover stabilization, including scheduled after-hours work
