Windows Server 2012 introduces the next-generation Resilient File System (ReFS) which enables the innovative functionality called Storage Spaces with Clustered Shared Volumes (CSV). Microsoft has improved Storage Spaces in the R2 version by adding the ability to use SSDs for automated tiering and/or write-back caching. This Storage Spaces advancement provides a highly resilient, scalable, and cost-effective storage solution for business-critical (virtual or physical) deployments.
Deemed the Cloud OS, Storage Spaces as presented in Windows Server 2012 R2 (WS2012R2) delivers sophisticated storage virtualization capabilities empowering customers to use standardized commodity servers for multi-node deployments, integrated with Microsoft certified OS-agnostic storage enclosures such as DataON Storage Cluster-in-a-box platform
and JBOD enclosures
for unlimited scalability.
Storage Spaces introduces new features and enhancements surrounding scalability and performance of storage virtualization platforms. Storage Spaces can automatically tier data across hard disks(HDD) and solid state(SSD) drives in JBOD enclosures or in a Cluster-in-a-Box platform, such as the CiB-9470
, which are actually virtual hard drives that are placed on the storage pools that are presented to the operating system as volumes, looking just like a hard drive.
Storage Spaces includes new capabilities such as data deduplication, the next-generation Resilient File System (ReFS), Server Message Block (SMB) 3.0 protocol improvements, and creates storage pools to enable failover between multiple nodes.
DataON supports a "Start Small Grow Big" strategy by enabling users to connect the DNS product line with technology partners HBAs for five-nines availability with scale-out file server capabilities at a fraction of legacy storage hardware costs.
