Windows Server 2012 business value features
Server manager:
Simplified, single-UI management of multiple servers.
The expanded capabilities of Server Manager in Windows Server 2012 can help
facilitate multiserver tasks such as remote role and feature deployment to both
physical and virtual servers and custom server group creation.
IT professionals can provision servers and offline virtual hard disks from their
desktops without requiring physical access to the system or Remote Desktop
Protocol connections to each server. Administrators can manage groups of servers
collectively from within a single, integrated console, which enables them to respond
to business-critical problems with greater speed and agility.
Capabilities provided by the new Server Manager include:
• Multiserver experience
• Efficient deployment of workloads to remote servers and offline virtual hard disks
• Installing roles and features on a remote server/offline virtual hard disk
• Streamlined server configuration and deployment
• Batch deployment
• Integration with other management tools
Storage spaces:
New virtualized storage by turning commodity hardware into virtual storage.
Storage Spaces is a storage virtualization technology which succeeds Logical Disk
Manager and allows the organization of physical disks into logical volumes similar to
Logical Volume Manager ( Linux
TM
), RAID1 or RAID5, but on a higher level.
A storage space will behave like a physical disk to the user, with thin provisioning
of available disk space. The spaces are organized within a storage pool (a collection
of physical disks), which can span multiple disks of different sizes and different
interfaces (USB, SATA, SAS). The process of adding new disks or replacing failed or
older disks is fully automatic, but can be controlled with PowerShell commands. The
same storage pool can host multiple storage spaces. Storage spaces have built-in
resiliency from disk failures, which is achieved by either mirroring or striping with
parity across the physical disks. Each storage pool on the ReFS filesystem is limited
to 4 PB (4096 TB), but there are no limits on the total number of storage pools or
the number of storage spaces within a pool.
• Storage Spaces technology automatically restores data redundancy if a disk fails.
• Ability to thin-provision storage.
• You can use PowerShell to manage storage spaces.
Storage live migration:
More VHDs with minimal downtime risk and cost.
