Also included are host configuration details and instructions for installing guest virtual machines of different types, PCI device configuration and SR- IOV. What is in This Guide? This guide provides information on installing virtualization software and configuring guest machines on a Red Hat Enterprise Linux virtualization host. The initial chapters in this guide outline the prerequisites to enable a Red Hat Enterprise Linux host machine to deploy virtualization. System requirements, compatible hardware, support and product restrictions are covered in detail. Guest virtual machine installation is covered in detail starting from Chapter 6, Guest Virtual Machine Installation Overview, with procedures for installing fully virtualized Red Hat Enterprise Linux guests and Windows paravirtualized guests using virt- manager and virsh. More detailed information on networking, PCI device configuration, SR- IOV, KVM guest timing management, and troubleshooting help for libvirt and SR- IOV is included later in the guide. Chapter 2. System Requirements. This chapter lists system requirements for successfully running virtual machines, referred to as VMs on Red Hat Enterprise Linux 6. Virtualization is available for Red Hat Enterprise Linux 6 on the Intel 6. AMD6. 4 architecture. The KVM hypervisor is provided with Red Hat Enterprise Linux 6. Minimum system requirements. Technical articles, content and resources for IT Professionals working in Microsoft technologies. Directory of hundreds of tools for monitoring and analyzing network traffic. GB free disk space. GB of RAM. Recommended system requirements. One processor core or hyper- thread for the maximum number of virtualized CPUs in a guest virtual machine and one for the host. GB of RAM plus additional RAM for virtual machines. GB disk space for the host, plus the required disk space for each virtual machine. Most guest operating systems will require at least 6. GB of disk space, but the additional storage space required for each guest depends on its image format. For guest virtual machines using raw images, the guest's total required space (total for raw format) is equal to or greater than the sum of the space required by the guest's raw image files (images), the 6. GB space required by the host operating system (host), and the swap space that guest will require (swap). Equation 2. 1. Calculating required space for guest virtual machines using raw imagestotal for raw format = images + host + swap. For qcow images, you must also calculate the expected maximum storage requirements of the guest (total for qcow format), as qcow and qcow. To allow for this expansion, first multiply the expected maximum storage requirements of the guest (expected maximum guest storage) by 1. Equation 2. 2. Calculating required space for guest virtual machines using qcow imagestotal for qcow format = (expected maximum guest storage * 1. Guest virtual machine requirements are further outlined in the Red Hat Enterprise Linux 6 Virtualization Administration Guide in Chapter 6. Overcommitting with KVM. Calculating Swap Space. Using swap space can provide additional memory beyond the available physical memory. The swap partition is used for swapping underused memory to the hard drive to speed up memory performance. The default size of the swap partition is calculated from the physical RAM of the host. KVM Requirements. The KVM hypervisor requires. Intel processor with the Intel VT- x and Intel 6. AMD processor with the AMD- V and the AMD6. Refer to the Red Hat Enterprise Linux 6 Virtualization Administration Guide to determine if your processor has the virtualization extensions. Storage Support. The guest virtual machine storage methods are. LUNs. LVM partitions. NFS shared file systems. GFS2 clustered file systems. Fibre Channel- based LUNs, and. Fibre Channel over Ethernet (FCo. E). Chapter 3. KVM Guest Virtual Machine Compatibility. To verify whether your processor supports the virtualization extensions and for information on enabling the virtualization extensions if they are disabled, refer to the Red Hat Enterprise Linux Virtualization Administration Guide. Red Hat Enterprise Linux 6 Support Limits. Red Hat Enterprise Linux 6 servers have certain support limits. The following URLs explain the processor and memory amount limitations for Red Hat Enterprise Linux. The following URL is a complete reference showing supported operating systems and host and guest combinations. Supported CPU Models. Every hypervisor has its own policy for which CPU features the guest will see by default. The set of CPU features presented to the guest by QEMU/KVM depends on the CPU model chosen in the guest virtual machine configuration. CPU models but there are other models (with additional features) available. Red Hat Enterprise Linux 6 supports the use of the following QEMU CPU model definitions. This is only a partial file, only containing the CPU models. The XML file has more information (including supported features per model) which you can see when you open the file yourself - ->.

Websitewww. microsoft. Microsoft SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network (including the Internet). Microsoft markets at least a dozen different editions of Microsoft SQL Server, aimed at different audiences and for workloads ranging from small single- machine applications to large Internet- facing applications with many concurrent users. History[edit]The history of Microsoft SQL Server begins with the first Microsoft SQL Server product – SQL Server 1. OS/2 operating system in 1. As of December 2. Microsoft SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of.

R2. SQL Server 2. SQL Server 2. 01. SQL Server 2. 01. The current version is Microsoft SQL Server 2. June 1, 2. 01. 6. The RTM version is 1. SQL Server 2. 01. SQL Server 2. 01. Preview and is available for download on Microsoft's site. Editions[edit]Microsoft makes SQL Server available in multiple editions, with different feature sets and targeting different users. These editions are: [4][5]Mainstream editions[edit]Enterprise. SQL Server Enterprise Edition includes both the core database engine and add- on services, with a range of tools for creating and managing a SQL Server cluster. It can manage databases as large as 5. CPU cores).[6]Standard. SQL Server Standard edition includes the core database engine, along with the stand- alone services. It differs from Enterprise edition in that it supports fewer active instances (number of nodes in a cluster) and does not include some high- availability functions such as hot- add memory (allowing memory to be added while the server is still running), and parallel indexes. Web. SQL Server Web Edition is a low- TCO option for Web hosting. Business Intelligence. Introduced in SQL Server 2. Self Service and Corporate Business Intelligence. It includes the Standard Edition capabilities and Business Intelligence tools: Power. Pivot, Power View, the BI Semantic Model, Master Data Services, Data Quality Services and x. Velocity in- memory analytics.[7]Workgroup. SQL Server Workgroup Edition includes the core database functionality but does not include the additional services. Note that this edition has been retired in SQL Server 2. Licensing. Clear explanations of current Microsoft licensing rules, programs and terminology give you the information and understanding you need to optimize your. Before you install any Microsoft Office 2013 product, verify that your computer meets or exceeds the minimum system requirements for the product. Express. SQL Server Express Edition is a scaled down, free edition of SQL Server, which includes the core database engine. While there are no limitations on the number of databases or users supported, it is limited to using one processor, 1 GB memory and 1. GB database files (4 GB database files prior to SQL Server Express 2. R2).[9] It is intended as a replacement for MSDE. Two additional editions provide a superset of features not in the original Express Edition. The first is SQL Server Express with Tools, which includes SQL Server Management Studio Basic. SQL Server Express with Advanced Services adds full- text search capability and reporting services.[1. Specialized editions[edit]Azure. Azure SQL Database is the cloud- based version of Microsoft SQL Server, presented as a platform as a service offering on Microsoft Azure. Compact (SQL CE)The compact edition is an embedded database engine. Unlike the other editions of SQL Server, the SQL CE engine is based on SQL Mobile (initially designed for use with hand- held devices) and does not share the same binaries. Due to its small size (1 MB DLL footprint), it has a markedly reduced feature set compared to the other editions. For example, it supports a subset of the standard data types, does not support stored procedures or Views or multiple- statement batches (among other limitations). It is limited to 4 GB maximum database size and cannot be run as a Windows service, Compact Edition must be hosted by the application using it. The 3. 5 version includes support for ADO. NET Synchronization Services. SQL CE does not support ODBC connectivity, unlike SQL Server proper. Developer. SQL Server Developer Edition includes the same features as SQL Server Enterprise Edition, but is limited by the license to be only used as a development and test system, and not as production server. Starting early 2. Microsoft made this version free of charge to the public.[1. Embedded (SSEE)SQL Server 2. Embedded Edition is a specially configured named instance of the SQL Server Express database engine which can be accessed only by certain Windows Services. Evaluation. SQL Server Evaluation Edition, also known as the Trial Edition, has all the features of the Enterprise Edition, but is limited to 1. Fast Track. SQL Server Fast Track is specifically for enterprise- scale data warehousing storage and business intelligence processing, and runs on reference- architecture hardware that is optimized for Fast Track.[1. Local. DBIntroduced in SQL Server Express 2. Local. DB is a minimal, on- demand, version of SQL Server that is designed for application developers.[1. It can also be used as an embedded database.[1. Analytics Platform System (APS)Formerly Parallel Data Warehouse (PDW) A massively parallel processing (MPP) SQL Server appliance optimized for large- scale data warehousing such as hundreds of terabytes.[1. Datawarehouse Appliance Edition. Pre- installed and configured as part of an appliance in partnership with Dell & HP base on the Fast Track architecture. This edition does not include SQL Server Integration Services, Analysis Services, or Reporting Services. Discontinued editions[edit]MSDEMicrosoft SQL Server Data Engine / Desktop Engine / Desktop Edition. SQL Server 7 and SQL Server 2. Intended for use as an application component, it did not include GUI management tools. Later, Microsoft also made available a web admin tool. Included with some versions of Microsoft Access, Microsoft development tools, and other editions of SQL Server.[1. Personal Edition. SQL Server 2. 00. Had workload or connection limits like MSDE, but no database size limit. Includes standard management tools. Intended for use as a mobile / disconnected proxy, licensed for use with SQL Server 2. Standard edition.[1. Datacenter. SQL Server 2. R2 Datacenter is a full- featured edition of SQL Server and is designed for datacenters that need high levels of application support and scalability. It supports 2. 56 logical processors and virtually unlimited memory and comes with Stream. Insight Premium edition.[1. The Datacenter edition has been retired in SQL Server 2. SQL Server 2. 01. Enterprise Edition.[8]Architecture[edit]The protocol layer implements the external interface to SQL Server. All operations that can be invoked on SQL Server are communicated to it via a Microsoft- defined format, called Tabular Data Stream (TDS). TDS is an application layer protocol, used to transfer data between a database server and a client. Initially designed and developed by Sybase Inc. Sybase SQL Server relational database engine in 1. Microsoft in Microsoft SQL Server, TDS packets can be encased in other physical transport dependent protocols, including TCP/IP, named pipes, and shared memory. Consequently, access to SQL Server is available over these protocols. In addition, the SQL Server API is also exposed over web services.[5]Data storage[edit]Data storage is a database, which is a collection of tables with typed columns. SQL Server supports different data types, including primary types such as Integer, Float, Decimal, Char (including character strings), Varchar (variable length character strings), binary (for unstructured blobs of data), Text (for textual data) among others. The rounding of floats to integers uses either Symmetric Arithmetic Rounding or Symmetric Round Down (fix) depending on arguments: SELECT Round(2. Microsoft SQL Server also allows user- defined composite types (UDTs) to be defined and used. It also makes server statistics available as virtual tables and views (called Dynamic Management Views or DMVs). Microsoft Excel 2. Advanced Training. Description.
