Lesson 1Object storage internals: eventual consistency, REST APIs, buckets, metadata, scalability and use casesDis section look inside object storage systems, focus pon RESTful access, buckets, an metadata. Learners study eventual consistency, distribution an scaling ways, an di jobs dat benefit most from object storage designs.
Buckets, objects, an key namingREST APIs an common operationsEventual consistency behaviorsMetadata indexing an searchScaling out capacity an throughputObject storage use cases an limitsLesson 2Cloud storage models: IaaS block storage, managed file storage, object storage, and differences from on-premises storageDis section explore cloud storage options, including IaaS block, managed file, an object storage. Learners compare durability, performance, an cost, an see how cloud services differ from traditional on-premises storage designs an operations.
IaaS block storage characteristicsManaged cloud file storage servicesCloud object storage featuresDurability, availability, an SLAsCost models an lifecycle policiesHybrid an multicloud storage patternsLesson 3RAID families and trade-offs: RAID 0/1/5/6/10, rebuild behavior, write penalty, and when to use eachDis section detail major RAID levels, including 0, 1, 5, 6, an 10, an how dem balance performance, capacity, an resilience. Learners analyze rebuild behavior, write penalties, an practical guidance pon selecting RAID fi various jobs.
RAID 0, 1, 5, 6, 10 fundamentalsParity, mirroring, an striping basicsWrite penalty an random I/O impactRebuild times an failure riskRAID selection fi key jobsRAID vs. erasure coding overviewLesson 4Block storage vs. file storage vs. object storage: definitions, access patterns, metadata differencesDis section define block, file, an object storage an how applications interact wid each. Learners compare access patterns, namespace organization, an metadata handling to understand which model best suit different job types.
Block storage concepts an LUN usageFile storage namespaces an sharesObject storage flat namespace modelMetadata handling in each modelTypical job access patternsChoosing di right storage modelLesson 5Storage area network (SAN): Fibre Channel and iSCSI basics, LUNs, zoning, multipathingDis section introduce SAN concepts, including Fibre Channel an iSCSI, an how dem present block devices as LUNs. Learners explore zoning, masking, an multipathing to design resilient, high-performance shared storage fabrics.
SAN vs. NAS: conceptual differencesFibre Channel fabric fundamentalsiSCSI concepts an connectivityLUN provisioning an maskingZoning strategies an securityMultipathing an path failoverLesson 6Direct-attached storage (DAS): architecture, use cases, limitations, performance characteristicsDis section examine direct-attached storage, where disks connect directly to a host. Learners review common architectures, performance behavior, scalability limits, an when DAS is appropriate compared wid NAS or SAN based solutions.
Typical DAS hardware topologiesLocal RAID controllers an JBODPerformance traits an bottlenecksScalability an manageability limitsDAS use cases an best fitsComparing DAS wid NAS an SANLesson 7Network-attached storage (NAS): protocols (SMB, NFS), typical deployments, concurrency and permissionsDis section introduce NAS concepts, focus pon how SMB an NFS expose shared folders over di network. Learners examine deployment patterns, concurrency handling, an permission models dat protect data an control multiuser access.
NAS vs. file server: key differencesCore NAS components an data pathsSMB protocol basics an capabilitiesNFS protocol basics an versionsPermissions, ACLs, an identity mappingTypical NAS deployment patternsLesson 8Performance metrics and capacity metrics: IOPS, throughput, latency, capacity planning basics, utilization and growth forecastingDis section explain key performance an capacity metrics, including IOPS, throughput, latency, an utilization. Learners practice interpreting metrics, planning capacity, an forecasting growth to maintain reliable, efficient storage systems.
