About the Job

Systems / Virtualization Engineer: DC-B vCenter build, ESXi config, v Motion /Replication integration, UAT coordination

Storage Engineer: DC-B storage array config, LUN/datastore provisioning, replication solution configuration, failover group configuration(s), DC-A decommission

Backup Engineers(Sys/Virt, Storage): Maintain workstream knowledge; attend critical windows; assume primary if needed (~25% of primary)



Scope of Work:



• Program management for all phases through DC-Adecommission: schedule, budget tracking, risk register, CAB ticket coordination, weekly status reporting, and stakeholder communications.

• DC-B storage array configuration: array initialization, RAID/pool creation, LUN/volume provisioning per tier, FC zoning or iSCSI/NFS configuration, and presentation of storage to DC-B ESXi hosts; documented in the DC-B Storage & vCenter Build Record.

• DC-B vCenter infrastructure build: ESXi host configuration, vCenter Server deployment, cluster/HA/DRS, distributed virtual switch and port group build (to VLAN spec provided by Presidio/Targa), data store mount/validation, and host-level readiness validation.

• Replication solution deployment and replication: Install/licensing at DC-B, Integration on all DC-B hosts, replication group configuration(s), initial seeding, failover-settings configuration, and pre-migration failover testing per tier.

• VM migration waves — Wave 1 (Tier 3), Wave 2 (Tier 2),Wave 3 (Tier 1 critical): Replication Move or vMotion execution and application-owner UAT coordination.

• DC-A decommission of SIS-owned components: Replication solution DC-A uninstall and coordination of physical decommission logistics.

• Replication status monitoring throughout the engagement; notification to Targa Resources if RPO thresholds are breached.

• Post-migration deliverables: final architecture handover document, project completion report, retrospective, and Replication/Archive runbook



Network Connectivity —Presidio Responsibility



All network connectivity, configuration, testing, and validation is owned and executed by Presidio as Targa Resources’ network service provider. This includes, without limitation:

• All VNI/VXLAN/BGP EVPN fabric configuration, modification, and testing at DC-A and DC-B.

• All routing changes — BGP metric adjustments, static route updates, route-policy changes — on any network device.

• All IPSec remote-site transitions: IKE gateway activation, tunnel cutover, traffic routing changes, 5-day hold management, and DC-A tunnel decommission for all remote sites.

• All Palo Alto firewall policy changes, zone updates, Dynamic Address Group membership changes, and security-rule modifications.

• Remote-site connectivity testing/validation: confirming each site can reach DC-B subnets before VM migrations begin; EVPN route validation, BGP table checks, PA FIB checks, and all network-layer post-change testing.

• Network rollback execution if a connectivity issue is identified before, during, or after a maintenance window.
