Management Improvements in 2008 R2 Flashcards
NLB
Remove-WindowsFeature NLB -restart
Core Parking
monitors multi-core processor power in a data center’s processor workload and consolidates it on fewer cores when utilization is low.
2008 R2 Improvements
Remote mgmt
Graphical mgmt consoles
command line automated scripts
Best Practice Analyzer (BPA)
windows powershell cmdlets
Changes to roles and features
BrancheCache -reduces network bandwidth needs for RDP clients
Ink and Handwriting services - support for handwriting, stylus, and touch screens
Direct Access Mgmt console - access and monitoring
Windows Biometric Framework, allows for fingerprint detection devices
WinRM - Windows Remote Management, IIS extension, enables servers to receive remote mgmt requests from clients
XPS viewer is now a standalone feature - but no support for 2000 message queing
Windows Server Migration Tool
Remote Server Administration Tool includes AD Admin Center, RD Connection Broker Tools, BitLocker Recovery Password Viewer

Terminal Services is now know as Remote Desktop Services
Print Service is now known as Print and Document Services
WSUS
Windows Server Update Service comes with R2, before you had to download it.
2008 R2 deployment of roles and features
powershell cmdlets
servermanagercmd.exe
They install or remove roles, role services, features
Before you can work with the servermanager cmdlets
you must load them ea in a new powershell session.
Import-Module Servermanager or r. click icon and choose
You need to enable script exectuion on the system before you can load modules
Remote mgmt supported scenarios
Server to Server
Server to Core Server
Client to Server
Security considerations are the same for powershell as for servermanger - modifications of .DDLs, sensitive data in the log file. log files don’t contain sensitive data or account info such as passwords
things you can do on a remote machine through server manager
- view automatic update status
- Best Practices Analyzer scans on roles
- Cofig Error Reporting
- Viewing and managing roles and services from role home pages
- CEIP changes Windows Customer Experience program
- Viewing or changing firewall
- viewing IE advanced security config settings
before you can config rdp, GPOs need to be enabled
Remote Event Log mgmt
Remote Service Mgmt
Windows Firewall remote mgmt
to config listeners, gpedit, computer config, admin templates
windows remote mgmt, winrm Service, allow automatic config of listeners and enable
to config new rules windows settings, security settings, windows firewall with advanced security, new inbound rule
BPA measures compliance with rules in 8 categories of a role’s efficacy, security and reliability
BPA Gui allows scanning a single unit.

processor power management
less storage power consumption
reduced power consumption by mulit-core proecessors
improvements:
core parking
managing CPU States
Using a SAN
3 states
Processor performance states defined by the ACPI specs as P-states
Linear stop throttle states, defined as ACPI specs as T-states
and processor idle sleep states, defined by the ACPI specifications as C-states
3 different behaviors and control mechanisms are:
dependent control
independent control
independent control and behavior
Intelligent Timer Tick Distribution or Tick Skipping
extends a processor sleep state to idle or not on unless necessary. One processor is assigned this
Power magmt controls
wireless adapter power settings
hybrid sleep
USB selective suspend, hdd to turn off connecton without bothering clients
PCI express bus power mmgmt
MIn an dMax processor state
power savings mode for search and indexing
Adaptive display control, which automaticaly reduces the grightness level of an inttegrated display control -adjust brightness
LInear stop clock throttle states
multi core processor power consumptions c uts off CPU performacne baed on redessors work load as viewed over a specific amount of time
SANS enhancements
ATA slumber
Optimized link power mgmt - sata hdd and chipset
asynchronous notification of media changes - dont have to keep sending commdlets
Support for solid state drives - aka SSDs are less power than mechanical drives, no moving parts
powershell cmdlets

AD LDS = adlsds
New-ADComputer -SamAccountName
New-AdUser -SamAccountName
-Account Password
-Enabled
in order to manage AD, AD LDS, AD Database mounting Tool using powershell you have to have
2008 R2 DC
one instance of an AD LDS config running on 2008 R2
AD module gets installed by default when you
dcpromo.exe
AD DS or AD LDS server role is installed
Windows 7 computer or 2008 R2 server install RSAT - Remote Server Administration Tools
several new and updated feature that contribute to improved wokrload size, scalability, availability
New cpu archetecture - as many as 256 logical processsors, hper v 64,
increased OS componentization
improved performance and scalability
Improved storage solutions
improved protection of intranet resources
performance improvements
wire speed storage by decreasing processor involvement in storage processes
storage input and output process
better use of multiple paths between servers and storage
enhanced connection performance for iSCSI-attached storage
optimization of the storage subsystem
quicker OS startups
NAP works with
IPsec 802.1x authentication for wired and wireless access for remote VPNs DHCP address allocation TS, Terminal services, gateway access
NPS improvements
automated SQL logging setup enhanced NPS logging NAP multiple config of SHV Templates migration of 2003 IAS servers (internet authentication servers)
NLB improvements
Network load balancer
can only use TCP/IP with TCP or UDP port
support for apps and services that need persisten connections
health monitoring and awareness of apps and services
next generation TCP/IP
multiple IP addresses
Integration of Microsoft ISA Server
extended affinity
powershell for nlb clusters
rolling updates
simultaneous users by distribution over cluster node
enables TCP/IP reqeusts to multiple systems to facilitate the best possible use of resources, reduce computing time and to ensure system availability
csv benefits
clustered shared volume
must be 2008 R2 hyper v
easier storage mgmt
resilient to failures
consistent namespace for all the nodes in the cluster
storing many VMs on one LUN and configuring them to fail over individually
No need for special hardware or other considerations
backup
windows server backup console mmc
command line tools - wbadmin
powershell cmdlets
wbadmin start systemstatebackup used to run jog once
wbadmin start backup is used to schedule state backups
must have VSS writer and application must be running in order for job to run
apps can only be backed up to hdd or remote shared folders, not removable media
