Simplified management of the server core with a menu driven tool
Remote management is enabled by default
Firewall must be configured to allow Remote Management
For legacy machines, run winrm quickconfig
To enable remote management, type Configure-SMRemoting.exe -enable, and then press Enter.
Enable-NetFirewallRule -DisplayGroup "Remote Administration"
Use Power Shell to do this
Add Remove features with DISM
Winrm
NIC teaming is new
Can do multi-server management easily--create server groups to keep track of servers
Netdom and Netsh are still available, but sconfig is much easier to use
Win RM implementation of WS management--a standard (usually MSFT is proprietary)
Successor to SNMP
Remote Desktop is also available but is a different process (may knock user offline)
Winrm.cmd QC enables it the QC=quick config
The easiest way to configure and make secure is to deploy the full then go to Core after you've configured it.
Minimal Shell is Server-Gui-Mgmt-infra
Can start with full and remove Server-Gui-Shell or
Start with Core and add Server-Gui-Mgmt-Infra
Remove Graphical Uninstall-WindowsFeature Server-Gui-Mgmt-Infra -restart
Add Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell -Restart
SC Command
NIC Teaming
Allows multiple NIC's to work as one--increase bandwidth or reliability
Can configure teaming to all use same switch--higher Bandwidth, or
Can configure the NIC's of the team to use different switches--reliability
Use packet hashing to identify which NIC the traffic belongs to.
Team can be active-active, or active-standby
Static Team--Manual Configuration of Switch
Switch Independent allows each NIC to be on different switch
LACP--Dynamic Teaming
Enabled from Server Manager
Add NIC's to the team and the team gets an ip address
When add Active directory, netbios is still there.
Powershell is an integral part of 2012 server configurations.
Resilient File System (ReFS)
Windows Server 2012 now includes a brand-new file system called Resilient File System (ReFS). ReFS was created to help Windows Server 2012 maximize the availability of data and online operation. ReFS allows the Windows Server 2012 system to continue to function despite some errors that would normally cause data to be lost or for the system to be down. ReFS uses Data integrity to protect your data from errors and also to make sure that all of your important data is online when that data is needed.One of the issues that IT members have had to face over the years is the problem of rapidly growing data sizes. As we continue to rely more and more on computers, our data continues to get larger and larger. This is where ReFS can help out an IT department. ReFS was designed specifically with the issues of scalability and performance in mind, and this resulted in some of the following ReFS features:
Availability If your hard disk becomes corrupt, ReFS has the ability to implement a salvage strategy that removes the data that has become corrupted. This feature allows the healthy data to continue to be available while unhealthy data is removed. All of this can be done without taking the hard disk offline.
Scalability One of the main advantages of ReFS is the ability to support volume sizes up to 2^78 bytes using 16 KB cluster sizes, while Windows stack addressing allows 2^64 bytes. ReFS also supports file sizes of 2^64-1 bytes, 2^64 files in a directory, and the same number of directories in a volume.
Robust Disk Updating ReFS uses a disk updating system referred to as an allocate-on-write transactional model (also known as copy on write). This model helps to avoid many hard disk issues while data is written to the disk because ReFS updates data using disk writes to multiple locations in an atomic manner instead of updating data in place.
Data Integrity ReFS uses a check-summed system to verify that all data that is being written and stored is accurate and reliable. ReFS always uses allocate-on-write for updates to the data, and it uses checksums to detect disk corruption.
Application Compatibility ReFS allows for most NTFS features and also supports the Win32 API. Because of this, ReFS is compatible with most Windows applications.
