VMware is a software that offers virtualization and cloud computing services. Based in Palo Alto, California, the company was founded in 1998 as a subsidiary of Dell Technologies. Before becoming a subsidiary of Dell Technologies, VMware was acquired by EMC Corporation in 2004. In 2016, Dell Technologies acquired EMC and became the sole owner of VMware. VMware virtualization technology is based on its bare-metal hypervisor ESX/ESXi in an x86 system.


How VMware Works

When virtualizing a server, a hypervisor is installed on the actual server to allow numerous virtual machines (VMs) to run on a single server. This technology allows each VM to operate an independent operating system (OS). Thus, a single server can support multiple OSes. One of the advantages of using VMware is that all VMs can share information and resources within the same server, including RAM and networking.

In 2019, VMware introduced containerized workloads support using Kubernetes cluster in the hypervisor. These workloads can be managed by the system managers, like the way virtual machines are operated. Additionally, the DevOps teams can deploy containers, in the same manner, as previously.

Scott Devine, Diane Greene, Mendel Rosenblum, Edouard Bugnion, and Edward Wang were the founders of VMware. The first product was launched in 1999, and an upgraded ESX was released in 2001.

The current CEO of VMware is Patrick Gelsinger, who started in 2012. The company's services include networking and security management tools, data center, and storage software.

What Can VMware Do?

VMware vSphere is the virtualization products suite from VMware. Before 2009, this product was called VMware Infrastructure. It includes the following components: ESXi, vCenter Server, vSphere Client, and vMotion. The current version of the product is vSphere 6.7, which has three main versions: Standard, Enterprise Plus, and Platinum. VMware also provides two three-server kits to serve small and medium-sized firms, vSphere Essentials and Essentials Plus. With VMware Cloud on AWS, clients can run a cluster of vSphere hosts with vSAN and NSX in the Amazon platform while managing the system with VMware tools.

VMware NSX is a virtual networking service offered by the company. It was created after the acquisition of Nicera in 2012. Through NSX, admins can virtualize numerous network factors, allowing them to deploy, develop, and configure virtual networks and switches using software instead of hardware. Software overlays the hypervisor through the VM system. It will enable administrators to divide a network into multiple virtual networks. Other networking technologies operating with the same approach are NSX-T Data Center, which allows network virtualization through ESXi and KVM as hypervisors. NSX-T Data Center can also enable Network Function Virtualization, which allows the running functions in a virtualized environment.

VMware vRealize Network Insight is another network operations and management tool that allows the admin to plan micro-segmentation and assess the VMware NSX health. This service was developed in 2016 after the acquisition of Arkin.

VMware offers numerous benefits to system users. It provides comprehensive security based on a zero-trust model compared to container systems like Kubernetes. There is also better sharing of resources and applications in a network. The data management is simplified and becomes manageable. VMware also increases the efficiency and agility of data center systems.

Background of VMware

VMware is a famous virtualization and cloud computing software vendor based in Palo Alto, California, United States. Established in 1998, the company was acquired by Dell Technologies. The company has expanded its customer base, mainly through partnerships and acquisitions by other technology firms. Its product portfolio has also grown, streamlining previous service versions and offering new products based on emerging customers' needs.

VMware virtualization technology is based on the hypervisor. The hypervisor ESX/ESXi runs in x86 architecture. These bare-metal hypervisors can run on the server's hardware without requiring primary operating systems. The technology is intended to allow several machines to operate from the same server. Therefore, workers need to have an account to access and share resources with other network members.

When the hypervisor is installed on a physical server, several virtual machines can be operated from the same server. One advantage is that each virtual machine can run a different Operating System. This is important because it allows users to choose the Operating System they are comfortable working with. Therefore, multiple operating systems can operate from the same server. Since the virtual machines operate on the same physical server, they can share files and resources, including RAM and networking.

As a company, VMware's primary services include networking and security management software, virtualization, software-defined data center software, and storage software. vSphere is an exceptional product from VMware that allows the virtualization of servers to manage and implement VM infrastructures on a broader scale. VMware vSphere is a cloud operating system or a virtualized data center that will enable administrators in companies to place works for applications in the most efficient computing resource available.

Benefits of Using VMware

The applications provided by VMware are intended to serve desktops and servers. VMware's desktop software is supported by different platforms, including Microsoft Windows, Linux, and Mac OS X. The desktop products or services include the VMware Workstation, VMware Player, and VMware Fusion. On the other hand, the server software provided by VMware includes VMware ESX Server, VMware ESXi Server, and VMware Server.

Since 2004, VMware has been a strong partner of SUSE Alliance. This ensures that Linux is supported physically or in the cloud in VMware software. This partnership has been crucial in offering reliable data virtualization solutions to businesses.

Another advantage of the collaboration is providing cloud services to VMware clients. SUSE and VMware have worked closely to streamline and strengthen cloud solutions for both public and private clouds. In the latest release of vSphere, the SUSE Linux Enterprise Server is certified and supported. This affirms the benefits that customers get from the partnership.

VMware is a leader in the virtualization and cloud computing sectors. The company provides high-quality services that can enhance business performance and streamline computing procedures. Moreover, it is easier for IT managers to regulate the use of resources by each worker, depending on their assigned responsibility. This makes VMware the best virtualization and cloud computing company. Many businesses can benefit from the services offered by VMware.

VMware Horizon Disk Latency and Other Resource Issues

When VMware Horizon users experience performance issues, IT must evaluate the resource consumption to identify the root cause and solve it. VDI resource use differs significantly from other infrastructure-related workloads like email servers or database servers. VDI administrators must be extra careful when managing resources like RAM and storage on virtual disks.

Different applications that are accessed through VDI, like VMware Horizon, making resource use less predictable. Another challenge arises from the VDI-mix for IOPS, which differs from other workloads. The percentage of writes from Windows virtual desktops is usually higher than server workloads, with a read-write ratio of 20/80 to 30/70.

Efficient operation requires IT to size a storage platform for such workloads. Planning can enhance user experience. Planning for storage in VMware Horizon must cover two main areas, performance, and capacity planning.

Capacity planning is achieved by simply multiplying the desktops available by the available storage required for each desktop. IT will establish the total capacity needed. Horizon administrators must include swap space for each machine, operational overhead factoring, and extra space for growth or expansion. Capacity planning also depends on the desktop type used. Full clones are like the size of the original virtual machine or linked or instant clones that store data for every virtual machine.

Despite the VMware clone type, administrators can follow a simple formula with a foreseen capacity. Besides, the Horizon environment is precise on disk space; increasing its capacity is simple.

Changing the storage platform is not easy, depending on the fit with the business needs. This step must be planned with future and present goals in perspective. IT must understand the current workloads and the homogeneity of the data. Depending on the user's responsibilities, the IOPS size will vary. Therefore, capacity planning can be achieved by measuring performance as people undertake their day-to-day work.

While total capacity and number of IOPS are vital, IT must also consider budget restrictions and skills when selecting a technology. VMware vSAN is an effective product because the administrator can manage it within vSphere. When subscribing to Advanced or Enterprise VMware Horizon, they automatically have vSAN. This is a cost-benefit approach for the Advanced subscription.

There are also technical approaches to understanding the causes of performance lags in virtual desktops. When VM is installed with Horizon agent, the performance tracker provides insight into the machine's performance statistics. However, the data does not include disk performance issues.

The performance tracker should also be run from the virtual desktop, limiting effectiveness. It is easier to collect data outside the user's session. The Helpdesk Tool enables the administrator to access performance information without interacting with workers. Subscription to the Enterprise Horizon license will offer access to all the tools. The vSphere client platform can also provide access to performance data without subscribing to the Advanced or Enterprise options.

When the issue causing performance challenges is identified, an advanced performance chart is available to understand the details. During the investigation of performance issues, it is also vital to compare observed and normal values. The main solution to disk performance issues is optimizing virtual desktops to save resource usage. These issues can include loading time and access to user profiles, which can cause challenges. If the issues persist, expanding the storage hardware components is essential. This enhances the bandwidth and storage adapter enhancements.
