Managing Storage Capacity Across Hybrid IT: A Practical Guide to Capacity Planning for On-Premises, Private Cloud, Public Cloud, and Hybrid Enterprise Storage (Site Reliability Engineering, Band 9) - Softcover

Inhaltsangabe

Storage capacity planning has quietly become one of the most consequential disciplines in enterprise IT — and one of the least understood outside a small circle of practitioners who learn it the hard way: through outages, budget overruns, and 2 a.m. escalations. Managing Storage Capacity Across Hybrid IT distills over forty years of enterprise infrastructure experience into a practical, chapter-by-chapter playbook for planning, forecasting, and defending storage capacity across on-premises data centers, private cloud, AWS, Microsoft Azure, Google Cloud, and everything in between.

This is not a vendor manual. It is a working reference for the infrastructure engineer, storage architect, or IT leader who has to answer hard questions with real numbers: How much headroom do we actually have? When will we run out? What will it cost? And how do we explain any of that to Finance?

Across thirty chapters organized into nine parts, the book covers:

• Foundational concepts — usable capacity, overcommit ratios, RAID overhead, and the true meaning of headroom
• Workload-aware performance capacity planning, including IOPS, latency, and throughput
• Platform-specific guidance for traditional SAN and NAS, VMware and private cloud, AWS, Azure, and Google Cloud
• Business alignment: working with Finance, chargeback and showback, executive reporting, and KPI selection
• Resilience, backup, cyber resilience, and disaster recovery sizing
• Cost optimization, operational rhythm, and building a capacity management team
• Sustaining executive sponsorship and measuring practice maturity over time

The book closes with five practical appendices — storage capacity formulas, a sample executive dashboard, a sample monthly capacity review, a KPI reference, and reference architectures — plus eight real-world case studies drawn from logistics, retail, financial services, healthcare, media, manufacturing, and insurance, each showing the framework applied under pressure.

Whether you are building a capacity management practice from scratch or refining one that already exists, this book offers a structured, vendor-neutral approach to a discipline that touches every workload an organization runs.
