Sql Server 2008 R2 Iso File
The SQL Server 2008 R2 ISO includes several "write" and data management features primarily focused on Business Intelligence (BI), scalability, and multi-server management. Key features found within the installation media include: Core "Write" and Data Management Features
Master Data Services (MDS): A new system that provides a central "single source of truth" for master data. It allows users to manage entities and hierarchies through a web-based interface, ensuring data consistency across multiple departments.
PowerPivot for Excel & SharePoint: These tools enable end-users to import, manipulate, and analyze massive datasets directly within the familiar Excel interface, then publish them to SharePoint for collaborative use.
Unicode Compression: SQL Server 2008 R2 uses the Simple Compression Scheme for Unicode (SCSU) algorithm, which can reduce the storage footprint for Unicode data by up to 50%, significantly improving I/O performance for write-heavy international applications.
StreamInsight: A platform designed for high-throughput processing of live data streams. It allows for parallel processing and simultaneous queries on "data in motion," which is ideal for real-time monitoring and event processing. Installation & Deployment Features
Data-Tier Application (DAC): This feature allows developers and DBAs to package database objects (schemas, tables, logins) into a single unit called a DAC package (or .dacpac). This simplifies the "writing" of database deployments and updates across different environments.
Sysprep Integration: The ISO supports SQL Server integration with Sysprep, allowing administrators to prepare an image of SQL Server on a virtual or physical machine and complete the configuration later, facilitating faster, standardized rollouts.
Application and Multi-Server Management (AMSM): Includes the SQL Server Utility, which provides a centralized dashboard (Utility Control Point) to monitor and manage resource utilization across multiple SQL Server instances. Edition-Specific Scalability
Datacenter Edition: Introduced in this release, it supports up to 256 logical processors and unlimited memory, targeting large-scale datacenter workloads.
Express Edition Upgrade: The maximum database size for the free Express edition was increased from 4GB to 10GB in this release. My favourite feature of SQL 2008 R2 - LobsterPot Solutions
