Enterprise software , also known as enterprise application software ( EAS ), is computer software used to satisfy the needs of an organization rather than its individual users. Enterprise software is an integral part of a computer-based information system , handling a number of business operations, for example to enhance business and management reporting tasks, or support production operations and back office functions. Enterprise systems must process information at a relatively high speed.
31-500: VMware ESXi (formerly ESX ) is an enterprise-class , type-1 hypervisor developed by VMware , a subsidiary of Broadcom , for deploying and serving virtual computers . As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel . After version 4.1 (released in 2010), VMware renamed ESX to ESXi . ESXi replaces Service Console (a rudimentary operating system) with

Certain industry-standard product categories have emerged, and these are shown below: Other types of software which do not fit into well-known standard categories, including backup software , billing management, and accounting software . Enterprise contract management software is used to bring all of an organisation's contractual commitments into
93-461: A Bridgeways ESX management pack gives the user a realtime ESX datacenter health view. Hardware vendors such as Hewlett Packard Enterprise and Dell include tools to support the use of ESX(i) on their hardware platforms. An example is the ESX module for Dell's OpenManage management platform. VMware has added a Web Client since v5 but it will work on vCenter only and does not contain all features. vEMan
124-480: A cost in the additional work the CPU has to perform to virtualize the underlying hardware. Instructions that perform this extra work, and other activities that require virtualization, tend to lie in operating system calls. In an unmodified operating system, OS calls introduce the greatest portion of virtualization "overhead". Paravirtualization or other virtualization techniques may help with these issues. VMware developed
155-577: A more closely integrated OS. ESX/ESXi is the primary component in the VMware Infrastructure software suite . The name ESX originated as an abbreviation of Elastic Sky X . In September 2004, the replacement for ESX was internally called VMvisor , but later changed to ESXi (as the "i" in ESXi stood for "integrated"). ESX runs on bare metal (without running an operating system) unlike other VMware products. It includes its own kernel. In
186-556: A purple diagnostic screen, the vmkernel writes debug information to the core dump partition. This information, together with the error codes displayed on the purple diagnostic screen can be used by VMware support to determine the cause of the problem. VMware ESX used to be available in two main types: ESX and ESXi, but as of version 5, the original ESX has been discontinued in favor of ESXi. ESX and ESXi before version 5.0 do not support Windows 8/Windows 2012. These Microsoft operating systems can only run on ESXi 5.x or later. VMware ESXi,
217-563: A range of business processes, information flows, reporting, and data analytics in complex organizations. While ES are generally packaged enterprise application software (PEAS) systems, they can also be bespoke, custom-developed systems created to support a specific organization's needs. Types of enterprise system include: Although data warehousing or business intelligence systems are enterprise-wide packaged application software often sold by ES vendors, since they do not directly support execution of business processes, they are often excluded from
248-496: A simple configuration console for mostly network configuration and remote based VMware Infrastructure Client Interface, this allows for more resources to be dedicated to the guest environments. Two variations of ESXi exist: The same media can be used to install either of these variations depending on the size of the target media. One can upgrade ESXi to VMware Infrastructure 3 or to VMware vSphere 4.0 ESXi. Originally named VMware ESX Server ESXi edition, through several revisions
279-410: A single monolithic system [has] failed for many companies". Enterprise software can be categorized by business function. Each type of enterprise application can be considered a "system" due to the integration with a firm's business processes. Categories of enterprise software may overlap due to this systemic interpretation. For example, IBM 's Business Intelligence platform ( Cognos ), integrates with
310-595: A single system for holistic management and to avoid the variability and inefficiency inherent in manual contracting processes. VMware Infrastructure VMware Infrastructure is a collection of virtualization products from VMware . Virtualization is an abstraction layer that decouples hardware from operating systems. The VMware Infrastructure suite allows enterprises to optimize and manage their IT infrastructure through virtualization as an integrated offering. The core product families are vSphere, vSAN and NSX for on-premises virtualization. VMware Cloud Foundation (VCF)
341-481: A smaller-footprint version of ESX, does not include the ESX Service Console. Before Broadcom acquired VMware, it was available - without the need to purchase a vCenter license - as a free download from VMware, with some features disabled. ESXi stands for "ESX integrated". VMware ESXi originated as a compact version of VMware ESX that allowed for a smaller 32 MB disk footprint on the host. With

#1732780928581372-518: Is a Linux application which is trying to fill that gap. These are just a few examples: there are numerous 3rd party products to manage, monitor or backup ESX infrastructures and the VMs running on them. As of September 2020, these are the known limitations of VMware ESXi 7.0 U1. Some maximums in ESXi Server 7.0 may influence the design of data centers: In terms of performance, virtualization imposes
403-498: Is a leader in the server-virtualization market, software and hardware vendors offer a range of tools to integrate their products or services with ESX. Examples are the products from Veeam Software with backup and management applications and a plugin to monitor and manage ESX using HP OpenView , Quest Software with a range of management and backup-applications and most major backup-solution providers have plugins or modules for ESX. Using Microsoft Operations Manager (SCOM) 2007/2012 with

The VMware Infrastructure suite is designed to span a large range of deployment types to provide maximum flexibility and scalability. The suite included: Users can supplement this software bundle by purchasing optional products, such as VMotion, as well as distributed services such as high availability (HA), distributed resource scheduler (DRS), or consolidated backup. VMware Inc. released VMware Infrastructure 3 in June 2006. The suite came in three "editions": Starter, Standard and Enterprise. Known limitations in VMware Infrastructure 3 may constrain
465-405: Is not well understood. Enterprise application software (EAS) is recognized among academics as enterprise software components and modules which support only a particular business function. These EAS software components and modules can interoperate, so that cross-functional or inter-organizational enterprise systems can be built up. In this context the industry may speak of middleware . Software that
496-620: Is primarily sold to consumers , is not called enterprise software. According to Martin Fowler , "Enterprise applications are about the display, manipulation, and storage of large amounts of often complex data and the support or automation of business processes with that data." Enterprise application software performs business functions such as order processing, procurement, production scheduling, customer information management, energy management, and accounting. Enterprise systems (ES) are large-scale enterprise software packages which support
527-479: Is used in industry, and business research publications, but is not common in computer science . The term was widely popularized in the early 1990s by major software vendors in conjunction with licensing deals with the show Star Trek In academic literature no coherent definition can be found. The computer historian Martin Campbell-Kelly contemplated in 2003 that the growth of the corporate software industry
558-638: The GPL . Programmers have adapted them to run with the vmkernel: VMware Inc. has changed the module-loading and some other minor things. In ESX (and not ESXi), the Service Console is a vestigial general purpose operating system most significantly used as bootstrap for the VMware kernel, vmkernel, and secondarily used as a management interface. Both of these Console Operating System functions are being deprecated from version 5.0, as VMware migrates exclusively to
589-632: The Virtual Machine Interface for this purpose, and selected operating systems currently support this. A comparison between full virtualization and paravirtualization for the ESX Server shows that in some cases paravirtualization is much faster. When using the advanced and extended network capabilities by using the Cisco Nexus 1000v distributed virtual switch the following network-related limitations apply: Regardless of
620-478: The ESXi model. The Service Console, for all intents and purposes, is the operating system used to interact with VMware ESX and the virtual machines that run on the server. In the event of a hardware error, the vmkernel can catch a Machine Check Exception. This results in an error message displayed on a purple diagnostic screen. This is colloquially known as a purple diagnostic screen, or purple screen of death (PSoD, c.f. blue screen of death (BSoD)). Upon displaying
651-486: The ESXi product finally became VMware ESXi 3. New editions then followed: ESXi 3.5, ESXi 4, ESXi 5 and (as of 2015) ESXi 6. VMware has been sued by Christoph Hellwig, a Linux kernel developer. The lawsuit began on March 5, 2015. It was alleged that VMware had misappropriated portions of the Linux kernel, and, following a dismissal by the court in 2016, Hellwig announced he would file an appeal. The appeal

#1732780928581682-503: The VMs running on it relies on virtual NICs (inside the VM) and virtual switches. The latter exists in two versions: the 'standard' vSwitch allowing several VMs on a single ESX host to share a physical NIC and the 'distributed vSwitch' where the vSwitches on different ESX hosts together form one logical switch. Cisco offers in their Cisco Nexus product-line the Nexus 1000v , an advanced version of
713-600: The VSM using the standard NX-OS CLI . It offers capabilities to create standard port-profiles which can then be assigned to virtual machines using vCenter. There are several differences between the standard dvS and the N1000v; one is that the Cisco switch generally has full support for network technologies such as LACP link aggregation or that the VMware switch supports new features such as routing based on physical NIC load. However,
744-626: The first virtual machine. VMware dropped development of ESX at version 4.1, and now uses ESXi, which does not include a Linux kernel at all. The vmkernel is a microkernel with three interfaces: hardware, guest systems, and the service console (Console OS). The vmkernel handles CPU and memory directly, using scan-before-execution (SBE) to handle special or privileged CPU instructions and the SRAT (system resource allocation table) to track allocated memory. Access to other hardware (such as network or storage devices) takes place using modules. At least some of
775-459: The historic VMware ESX, a Linux kernel was started first and then used to load a variety of specialized virtualization components, including ESX, which is otherwise known as the vmkernel component. The Linux kernel was the primary virtual machine; it was invoked by the service console. At normal run-time, the vmkernel was running on the bare computer, and the Linux-based service console ran as
806-519: The main difference lies in the architecture: Nexus 1000v is working in the same way as a physical Ethernet switch does while dvS is relying on information from ESX. This has consequences for example in scalability where the Kappa limit for a N1000v is 2048 virtual ports against 60000 for a dvS. The Nexus1000v is developed in co-operation between Cisco and VMware and uses the API of the dvS. Because VMware ESX
837-530: The modules derive from modules used in the Linux kernel . To access these modules, an additional module called vmklinux implements the Linux module interface. According to the README file, "This module contains the Linux emulation layer used by the vmkernel." The vmkernel uses the device drivers: These drivers mostly equate to those described in VMware's hardware compatibility list . All these modules fall under
868-456: The standard distributed vSwitch. A Nexus 1000v consists of two parts: a supervisor module (VSM) and on each ESX host a virtual Ethernet module (VEM). The VSM runs as a virtual appliance within the ESX cluster or on dedicated hardware (Nexus 1010 series) and the VEM runs as a module on each host and replaces a standard dvS (distributed virtual switch) from VMware. Configuration of the switch is done on
899-713: The term. Enterprise systems are built on software platforms, such as SAP's NetWeaver and Oracle's Fusion , and databases. From a hardware perspective, enterprise systems are the servers, storage and associated software that large businesses use as the foundation for their IT infrastructure . These systems are designed to manage large volumes of critical data and thus are typically designed to provide high levels of transaction performance and data security. The "seemingly boundless complexity" of enterprise systems has been criticised, and arguments maintained for deploying discrete systems for specific business tasks. Cynthia Rettig, an American businesswoman, has argued that "the concept of
930-526: The type of virtual SCSI adapter used, there are these limitations: Enterprise software Services provided by enterprise software are typically business-oriented tools. As companies and other organizations have similar departments and systems, enterprise software is often available as a suite of customizable programs. Function-specific enterprise software uses include database management, customer relationship management, supply chain management and business process management. The term enterprise software
961-761: Was decided February 2019 and again dismissed by the German court, on the basis of not meeting "procedural requirements for the burden of proof of the plaintiff". In the last stage of the lawsuit in March 2019, the Hamburg Higher Regional Court also rejected the claim on procedural grounds. Following this, VMware officially announced that they would remove the code in question. This followed with Hellwig withdrawing his case, and withholding further legal action. The following products operate in conjunction with ESX: Network-connectivity between ESX hosts and
