Server Manager

Why redesigned? How does it benefit admins?

Why Server Manager Redesigned?

Modern UI Style and the Local Server Experience• By default, Server Manager

starts when logging on to

server

• Administrative Tools available

from the Tools Menu

Window Server 2012 User Interface ChangesWhy should I care?

Why should I care?

The Windows Server 2012 solution… multiple interface options

• Allows administrators to use the same familiar graphical tools to administer the server without using remote management tools

• Removes the overhead of the other operating system elements not needed to perform that task

• Does not require a re-installation to modify the level of GUI on a server; modified in the same manner as any other role or feature

• Allows for a single server deployment image

The challenges…

• Lowering the attack footprint of the server to the smallest size possible while keeping it fully patched is a primary responsibility of administrators

• Many administrators are uncomfortable with only a minimal command-line interface (Server Core)

User Interface Changes

Windows Server 2012 allows you to have three levels of User

Interface:

• Server Core

•Traditional server core with command line only interface

• Minimal Installation Shell (“MinShell”)

•Server Core plus select UI elements such as MMC support

and Server Manager

• Full Shell

•Full Windows desktop, which can also include the Desktop

Experience

Windows PowerShell

What is it?

What is Windows PowerShell?PowerShell is a distributed automation engine with a scripting language and

interactive shell(s).

• Focuses on the business• Makes change safe through automation• Bridges the gap between Operators and Developers

PowerShell 3.0 is available for the following

Operating Systems:

• Built-in:• Windows Server 2012• Windows 8 (built-in)

• Downloadable for:• Windows 7 SP1• Windows Server 2008 SP2• Windows Server 2008 R2 SP1

Windows PowerShell

Why should I care?

Why should I care?

The Windows Powershell 3.0 solution….

• Allows for use of tested scripts, reducing the number of errors that impact production environments

• Improves efficiency due to the dramatic increase number of built-in cmdlets• Includes new features designed to speed understanding and correct usage of

syntax (Show-Command)• Makes excellent progress toward bridging the gap between Operators and

Developers

The challenge…

• Reduce errors during configuration changes• Reduce the skill set required for authoring automation of complex solutions• Locate and import the numerous PowerShell modules into each session• Reduce the syntax learning curve, especially for people new to PowerShell• Bridge the gap between Operators and Developers

Windows PowerShell

Technical Overview

What’s New for IT Professionals in PowerShell 3.0?Easier to Automate

• ~2,430 built-in cmdlets (compared with ~ 230 in Windows Server 2008/R2)• Skill level required to successfully automate complex solutions is reduced• Language and utility cmdlets are simplified to reduce steps and syntax• Improved authoring tools • PowerShell ISE supports rich Intellisense, snippets, 3rd party extensibility, and

a Show-Command window

Windows Workflow Foundation integration

• Operators can use any available Workflow designers to create workflows

Scheduled Jobs

• Seamless integration with Task Scheduler

Robust Networking

• PowerShell Remoting enabled by default• Disconnected session support

Storage Spaces

Overview

What is Storage Spaces & Thin Provisioning?Storage Spaces

• New in Windows Server 2012

• Provides an in-box storage virtualization that can use low-cost commodity storage devices

• Aggregates unallocated space on physical disks installed in or connected to servers through

a “pooling” model

• Can provide a cost-effective platform for business critical storage across a variety of

scenarios

Thin Provisioning

• “Just-in-Time” allocations of storage with the ability to reclaim storage (“Trim”)

• Integrated with Storage Spaces

Why should I care?

Storage pools

• Can be mapped to combinations of hard disks as well as solid-state drives

(SSDs)

• Can be expanded dynamically by simply adding additional drives, thereby

seamlessly scaling to cope with unceasing data growth

Multitenancy

• Administration of storage pools can be controlled through access control lists

(ACLs) and delegated on a per-pool basis

• Can be fully integrated with Active Directory Domain Services

Resilient storage

• Storage Spaces support two optional resiliency modes (mirroring and parity)

• Per-pool support for disks that are reserved for replacing failed disks (hot

spares), background scrubbing, and intelligent error correction allow

continuous service availability despite storage component failures

The features of Storage Spaces are designed to meet a variety of challenges in

support of highly-available storage

Why should I care? (cont.)

Continuous Availability

• Failover clustering integration delivers continuously available service

deployments

• One or more pools can be clustered across multiple nodes within a single

cluster. Storage spaces can then be instantiated on individual nodes, and the

storage will seamlessly fail over to a different node when necessary (in response

to failure conditions or due to load balancing)

• Integration with CSVs permits scale-out access to data

Optimal storage use through thin provisioning

• To allow businesses to easily share storage capacity among multiple unrelated

data sets and thereby maximize capacity use

• Trim support permits capacity reclamation when possible

Operational simplicity

• Easily managed through the File Services role in Server Manager

• Fully remoteable and scriptable management through the Windows Storage

Management API, WMI, and Windows PowerShell

• Designed to be compatible with existing backup-restore and cloning tools, as

well as snapshotting infrastructures

Storage Spaces

Technical Overview

Storage Spaces Requirements

• The criterion for determining which drives are eligible to be part of a Pool are:

• Minimum drive size is 10 GB

• Drive is empty, i.e. no partition data exists on the drive

• Drive is not assigned to any other pool

• The Primordial Pool will consist of Physical Disks that are not assigned to

any existing Storage Pool

• Windows Server 2012

• Serial ATA (SATA) or Serial Attached SCSI (SAS)

connected disks (in an optional just-a-bunch-of-

disks [JBOD] enclosure)

• Multinode clustered shared-storage deployments

• Two or more servers running Windows Server

2012

• Requirements as specified for failover

clustering and Windows CSV

• SAS connected JBODs that comply with

Windows Certification requirements

Web Application Deployment with IIS 8.0

Why should I care?

Why should I care?The challenges The IIS 8.0 solutions

Managing a large number of dedicated IP addresses for each

secure site

SNI uses the host name to identify the network endpoint so

multiple dedicated IP addresses are no longer needed

Taking full advantage of emerging high-performance

hardware systems

NUMA-Aware Scalability can help you take advantage of

emerging, high-performance server hardware systems for

greater efficiency, scalability and manageability

Managing resources across application pools IIS CPU Throttling is used to establish the maximum CPU

consumption allowed per application pool

Management of SSL certificates is time consuming and

costly

SSL certificate management is greatly simplified - no

certificates to import to each server; there is now support

for a centralized certificate store

Improving the speed of first connections to a web

application

Application Initialization helps to speed up the initialization

of websites

Protecting web sites from DoS and brute force attacks IP Address filtering can be dynamically filtered; FTP Logon

Attempt Restriction provides protection from brute-force

attacks

Supporting multiple types of applications on the same

server

Open Web Platform provides for support and management

of .NET 3.5, .NET 4.5 and open source applications

Application Initialization

• x Example modifications in applicationHost.config

Application pool configuration entry:

<add name=".NET v4.5" managedRuntimeVersion="v4.0" />

Application configuration entry:

<application path="/appinit" applicationPool=".NET v4.5">

Example modifications to application level web.config

<applicationInitialization skipManagedModules="true" >

<add initializationPage="/default.aspx" />

</applicationInitialization>
