The SAN dashboard shows intermittent latency spikes, but the root cause hides across layers and logs , and the operations team escalates every Monday morning.
The situation this course is for
As a senior IC, you're expected to resolve SAN performance issues fast, but the real challenge is fragmented data: array latency, host I/O patterns, fabric utilization, and hypervisor queues each live in separate tools. Correlating them manually takes hours, and tribal knowledge fills the gaps. The result: recurring Monday escalations, pressure from role instability at the employer level, and no standardized playbook to prevent repeat incidents.
Who this is for
Senior individual contributor SAN engineers in large-scale hybrid environments who own end-to-end performance diagnosis and resolution without dedicated cross-functional teams.
Who this is not for
Entry-level storage admins, cloud-only practitioners without SAN exposure, or managers seeking high-level overviews.
What you walk away with
- Identify the three most common root causes of SAN performance drift in under 15 minutes
- Correlate storage array, host, and hypervisor metrics using a repeatable triage checklist
- Stop recurring Monday escalations with an automated early-warning template
- Produce stakeholder-ready reports that close tickets faster
- Deploy a lightweight monitoring overlay that integrates with existing Rackspace tooling
