About The BookMore and more of VMware's half a million global customers are looking for new storage solutions which cost less, while still providing the same levels of performance, availability and scalability. With the traditional storage systems no longer meeting IT organization's needs, the market to gain knowledge in this area is significant. VMware's Virtual SAN and Virtual Volumes solutions are leading the way in the IT industry to drive efficiency, automation and simplification, while maintaining enterprise-class features and performance, making them the ideal storage platform for tomorrows virtual infrastructure.Foreword by Duncan EppingIntroduction Chapter 1 Software-Defined Storage Design Software-Defined Compute Software-Defined Networking2 Software-Defined Storage Designing VMware Storage Environments Technical Assessment and Requirements Gathering Establishing Storage Design Factors The Economics of Storage Calculating the Total Cost of Ownership for Storage Resources Information Lifecycle Management Implementing a Software-Defined Storage Strategy Software-Defined Storage Summary Hyper-Converged Infrastructure and Virtual SAN Virtual Volumes Classic and Next-Generation Storage Models Chapter 2 Classic Storage Models and Constructs Classic Storage Concepts RAID Sets Virtual Provisioning Storage Tiering Storage Scalability Design Storage Management Tools Multitenanted Storage Design Quality of Service Data Deduplication and Data Compression Storage Device Security Hardware High Availability Storage Array--Based Disaster Recovery and Backups Storage Array Snapshots and Clones in a Classic Storage Environment vSphere Metro Storage Cluster All-Flash Disk Arrays vSphere Storage Technologies Virtual Disks Virtual Machine Storage Controllers (vSCSI Adapters) Datastore Raw Device Mapping When to Use RDMs over VMFS or NFS?
