What is Storage Spaces & ThinProvisioning?Storage Spaces
New in Windows Server 2012 Provides an in-box storage virtualization that can use low-cost commodity st Aggregates unallocated space on physical disks installed in or connected to
a pooling model Can provide a cost-effective platform for business critical storage across a va
scenarios
Thin Provisioning Just-in-Time allocations of storage with the ability to reclaim storage (Trim Integrated with Storage Spaces

Why should I care?
Storage pools Can be mapped to combinations of hard disks as well as solid-state driv
(SSDs) Can be expanded dynamically by simply adding additional drives, there
seamlessly scaling to cope with unceasing data growthMultitenancy
Administration of storage pools can be controlled through access contr(ACLs) and delegated on a per-pool basis
Can be fully integrated with Active Directory Domain ServicesResilient storage
Storage Spaces support two optional resiliency modes (mirroring and p Per-pool support for disks that are reserved for replacing failed disks (h

Why should I care? (cont.)Continuous Availability
Failover clustering integration delivers continuously available servicedeployments
One or more pools can be clustered across multiple nodes within a singlecluster. Storage spaces can then be instantiated on individual nodes, and tstorage will seamlessly fail over to a different node when necessary (in respto failure conditions or due to load balancing)
Integration with CSVs permits scale-out access to dataOptimal storage use through thin provisioning
To allow businesses to easily share storage capacity among multiple unrela
data sets and thereby maximize capacity use Trim support permits capacity reclamation when possible
Operational simplicity Easily managed through the File Services role in Server Manager Fully remoteable and scriptable management through the Windows Storag
Management API, WMI, and Windows PowerShell Designed to be compatible with existing backup-restore and cloning tools,
well as snapshotting infrastructures

Storage Spaces Requirements
The criterion for determining which drives are eligible to be part of a Pool 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 assigne
any existing Storage Pool
Windows Server 2012 Serial ATA (SATA) or Serial Attached SCSI (SAS)
connected disks (in an optional just-a-bunch-of-disks [JBOD] enclosure)

Data Redundancy inStorage Spaces
RedundancyType
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 dis Increases reliability Reduces capacity by 13 to 33 percent

Managing Storage with PowerShell
Parameters configured with GUI and PowerShell
Underlying storage pool name Virtual disk name Resiliency setting (Simple, Mirror, or parity)
Provisioning type (Thin or Fixed) Virtual disk size
Parameters configured only with PowerShell
Number of columns: the number of columns thevirtual disk contains
Number of data copies - number of completecopies of data that can be maintained
Disk interleave - number of bytes forming a stripe Physical disks to use - specific disks to use in the
virtual disk
PowerShell is required to access many of the advanced
features afforded by the new Storage Management
application programming interface (API)
Example: New-StoragePool

Thin Provisioning and TrimRequirements
Enabled by default in Windows Server 2012
Storage infrastructure that complies with the certification that is required for Windows S
2012 Standards-compliant hardware for identification
Capabilities Identification
Windows Server 2012 uses a standardized method to detect and identify thinlyprovisioned virtual disks
Notification When configured physical storage use thresholds are reached, Windows Server 20
notifies the administrator through events; events can be used for automated actiosophisticated management applications, such as Microsoft System Center
Optimization Windows Server 2012 provides a new API that lets applications return storage whe
no longer needed. NTFS issues trim notifications in real time when appropriate. Trim notifications are issued as part of storage consolidation (optimization), which
performed regularly on a scheduled basis
