Windows Server 2012 R2 is cloud optimized
Private Clouds
Hosted Clouds
Cloud Service Providers
Reducing capital and operational
storage and availability costs
Windows Server 2012 R2 Focus Areas
Enabling Hosters and the Private Cloud
Three storage changes have already begun:
New options are decreasing the cost of
high-performance, scalable network storage
Customers are moving data to the cloud
Recovery and the cloud is becoming a reality
IT pain points
 Need offline files and secure data
 Data access over WANs driving need for
network optimization

Efficiently store, transfer and back up fewer bits.
Transparently removes duplication,
without changing access semantics.
Post-processing approach:
Role can be turned on
in Server Manager and
enabled on new
volumes.
Can be easily enabled
on existing data
volumes.
Can exclude specific file
types or select folders
to skip.
Process files in the
background or choose
a more aggressive
schedule.
Default setting is to
process files older than
5 days.
Not a deduplication
server.
Transparent to the
primary server
workload.
Designed to back-off if
the server needs
resources.
Protect against
hardware data
corruption.
Identify and repair
corruptions.

Checksum validation on all data and
metadata
Scrubbing job inspects corruptions and
tries to fix them
Extra copies of all metadata and popular
data chunks
Corrupted data replaced when possible:
• Redundant copies
• Storage Spaces mirroring
• Future chunks
Deduplication evaluation tool
No need to upgrade to evaluate
(available after installing the dedup feature)
• Determine expected savings
without altering your data.
• Runs on Windows 7 or newer, and on
Windows Server 2008 R2 or newer.
• Evaluate VHDs of running VMs.
• Evaluate data on SMB/CIFS shares, including
non-Windows servers.
Note: Dedup of remote shares is not supported,
but you can evaluate the data.
50-95% primary data
reduction, with less
data to backup, archive
and migrate.
Simple, fast and higher
density storage for VDI.
Support for open files
and CSV volumes.
No change to data
access semantics for
apps or users.
Minimal impact on
server resources.
Now support for live
VHDs for VDI over SMB.
Constant validation of
all data and metadata.
Redundancy for critical
metadata and popular
data chunks.
Repair corrupted data
from available sources.
Faster file downloads,
lower WAN bandwidth
use with BranchCache
integration.
Cached chunk data on
SMB server in Hyper-V
mode.
