  • 15. What is Storage Spaces & Thin Provisioning? Storage Spaces • New in Windows Server 2012 • Provides an in-box storage virtualization that can use low-cost commodity storage devices • Aggregates unallocated space on physical disks installed in or connected to servers through a ―pooling‖ model • Can provide a cost-effective platform for business critical storage across a variety of scenarios Thin Provisioning • ―Just-in-Time‖ allocations of storage with the ability to reclaim storage (―Trim‖) • Integrated with Storage Spaces
  • 16. Why Should You Care? The features of Storage Spaces are designed to meet a variety of challenges in support of highly-available storage Storage pools • Can be mapped to combinations of hard disks as well as solid-state drives (SSDs) • Can be expanded dynamically by simply adding additional drives, thereby seamlessly scaling to cope with unceasing data growth Multitenancy • Administration of storage pools can be controlled through access control lists (ACLs) and delegated on a per-pool basis • Can be fully integrated with Active Directory Domain Services Resilient storage • Storage Spaces support two optional resiliency modes (mirroring and parity) • Per-pool support for disks that are reserved for replacing failed disks (hot spares), background scrubbing, and intelligent error correction allow continuous service availability despite storage component failures
  • 17. Storage Spaces Requirements • Windows Server 2012 • Serial ATA (SATA) or Serial Attached SCSI (SAS) connected disks (in an optional just-a-bunch-ofdisks [JBOD] enclosure) • Multinode clustered shared-storage deployments • Two or more servers running Windows Server 2012 • Requirements as specified for failover clustering and Windows CSV • SAS connected JBODs that comply with Windows Certification requirements Drive Type Stand-Alone File Servers Clustered File Servers SATA Supported SCSI Supported iSCSI Supported Supported SAS Supported Supported USB Supported • The criterion for determining which drives are eligible to be part of a Pool are: • Minimum drive size is 10 GB • Drive is empty, i.e. no partition data exists on the drive • Drive is not assigned to any other pool • The Primordial Pool will consist of Physical Disks that are not assigned to any existing Storage Pool

  • 22. Data Redundancy in Storage Spaces Redundancy Type Description Simple • • • Data is striped across physical disks Maximizes capacity Increases throughput Mirror • • • Data is duplicated on two or three physical disks Increases reliability Reduces capacity by 50 to 66 percent Parity • • • Data and parity information are striped across physical disks Increases reliability Reduces capacity by 13 to 33 percent
