Windows Server 2012 and 2012 R2
a) Server Core role has enhance in 2012 server. Role available 12 out of 19 role.
2008 - 9 role, 2008 R2- 10 role
b) New feature has been added in 2012 server
"User Interfaces and Infrastructure"
Installing this feature you can decide if you want to work in Core or GUI mode. No need to reinstall for interchange of core or gui.
c) SQl server can be run in 2012 server core , SQL server can't be install in 2008 & 2008 R2 server core
d) Server Manager Interface has change significantly
From Server manager you can configure roles for multiple servers “All servers tab”
Right click "All servers"--- add server…
From "ADDS" tab you can see Active directory with services running, events, performance everything in one window view.
e) Storage Spaces
You can add multiple hard drives (internal & external) to create storage pool and later you can assign drive to that storage pool.
This support Redundancy. If any hd fails -no data loss
Supports thin provisioning (means- disk space on the drive is only required when it is needed) [disk Space is used when it is required]
f) Second generation FS has been introduced
ReFS (Resilient File System) - Self healing feature (automated recovery in corrupted file-live)
ReFS don't support Booting (system drive can't use)
Only can be used in data drive
Don't support Disk Quotas
Does not support EFS Encryption and compression
ReFS will work only in Windows 8 and Server 2012(new feature)
g) New protocol has been introduced for network file sharing
# SMB 3.0 with High Availability feature
Suppose user is not able to reach file share, they will be redirected to other network file share location with same data. User will not able to understand
# Transparent failover
h) Hyper-V has “1st generation configuration” & “2nd generation configuration” option, dynamic memory allocation
Basic difference between 2008 R1 and 2008 R2
The following changes are available in Windows Server 2008 R2:
Live migration with no down time
Dynamic virtual machine storage
Enhanced processor support (Multi core-- more than 64 core)
Enhanced networking support
a) Windows Server 2008 is 32 bit (R1) & Windows Server 2008 R2 is 64 bit
b) Windows Server 2008 supports 8 cores processor and
Server 2008 R2 supports multi core processors, more than 64 core processors
c) Virtualization and power management has enhanced
d) Better utilization of multi core
e) Offline domain joins in Server 2008 R2
f) Quick migration (downtime was required may be 30 sec or a minute) in 2008 &Live migration in server 2008 R2 (zero down time)- Paused option is there .
