Earlier this week, Dell announced support for Storage Spaces as provided by Windows Server.
Storage Spaces is a virtualization technology which groups disks into storage pools and allows for creation of virtual disks from that pool. It provides automatic storage tiering and disk resiliency.
Supported hardware includes Dell’s PowerEdge Servers, cost-effective SAS 6Gb/s host bus adapters (HBAs), persistent reservation HDDs and SSDs, and PowerVault MD1200 and MD1220 storage enclosures.
