Performance Best Practices for VMware vSphere 8

The Best Social Media Recommendations for your Software-Defined Data Center

Mastering VMware vSphere 6.7 Second Edition Effectively deploy, manage, and monitor your virtual datacenter with VMware vSphere 6.7 Martin Gavanda Andrea Mauro Paolo Valsecchi Karel Novak

The realm of technology is one that has traditionally been constructed on silos. We tend to fragment our skills into very specific areas of expertise, even going so far as to isolate the very people who run data center and cloud operations into little buckets of focus and energy. I’d like to think that this, more than anything, was the root cause for such painfully slow progress towards realizing the dream of a fully software defined data center. I had always felt a bit stifled by this organizational fragmentation and thirsted for a way to put my hands on just about any solution that shows the promise of removing the burden of manual processes. Since you’re reading this book, I’ll make the assumption that you have had similar thoughts.

VMware vSphere 8.0 is available in the following languages: • English • Italian • French • German • Spanish • Japanese • Korean • Simplified Chinese • Traditional Chinese Components of vSphere 8.0, including vCenter Server, ESXi, the vSphere Client, and the VMware Host Client, do not accept non-ASCII input. Compatibility Virtual Machine Compatibility for ESXi Virtual machines that are compatible with ESX 3.x and later (hardware version 4) are supported with ESXi 8.0. Virtual machines that are compatible with ESX 2.x and later (hardware version 3) are not supported. To use such virtual machines on ESXi 8.0, upgrade the virtual machine compatibility. See the ESXi Upgrade documentation. Guest Operating System Compatibility for ESXi To determine which guest operating systems are compatible with vSphere 8.0, use the ESXi 8.0 information in the VMware Compatibility Guide. The following guest operating system releases are deprecated or terminated in this release. Future vSphere releases will not support these guest operating systems: • Windows Vista, Windows 2003 / R2, Windows XP: Deprecated • Oracle Linux 5.x: Deprecated • Oracle Linux 4.9: Terminated • CentOS 5.x: Deprecated • Asianux 3.0: Deprecated • SUSE Linux Enterprise Server 9 SP4: Terminated • SUSE Linux Enterprise Server 10 SP4: Deprecated • SUSE Linux Enterprise Desktop 12: Deprecated • Ubuntu releases 12.04, 18.10, 19.04 and 19.10: Terminated • Debian 7.x and 8.x: Deprecated • Debian 6.0: Terminated • Photon OS 1.0: Terminated • Flatcar Container Linux non-LTS releases: Terminated • All OS X and macOS releases: Terminated • FreeBSD 9.x and 10.x: Deprecated • FreeBSD 7.x and 8.x: Terminated • Solaris 10.x: Deprecated • All eComStation releases: Terminated • All SCO releases: Terminated VMware by Broadcom 75VMware vSphere 8.0 • All CoreOS releases: Terminated Device Compatibility for ESXi To determine which devices are compatible with ESXi 8.0, use the ESXi 8.0 information in the VMware Compatibility Guide. Hardware Compatibility for ESXi To view a list of processors, storage devices, SAN arrays, and I/O devices that are compatible with vSphere 8.0, use the ESXi 8.0 information in the VMware Compatibility Guide. ESXi and vCenter Server Version Compatibility The VMware Product Interoperability Matrix provides details about the compatibility of current and earlier versions of VMware vSphere components, including ESXi, VMware vCenter Server, and optional VMware products.

It’s hard to believe how far we’ve come in the virtualization industry. What was once considered a niche technology used only for development and testing is now used for production work- loads and even business-critical applications. The VMware vSphere platform is capable of sup- porting nearly any virtualized workload with very few obstacles standing in the way of close to 100 percent virtualization. Today’s workloads are more demanding than ever before. Email servers frequently require large amounts of memory and CPU resources in order to handle the large volume of email that we all deal with on a daily basis. Database servers often require large amounts of memory and storage resources, from a capacity perspective as well as performance, to meet the demands of a business. And newer technologies, such as virtual desktop infrastructure (VDI), have intro- duced signii cant demand for resources in vSphere environments.

vSphere Upgrade describes how to upgrade VMware vSphere™ to the current version. To move to the current version of vSphere by performing a fresh installation that does not preserve existing conigurationsǰ see the vSphere Installation and Setup documentation. Intended Audience: vSphere Upgrade is for anyone who needs to upgrade from earlier versions of vSphere. These topics are for experienced Microsoft Windows or Linux system administrators who are familiar with virtual machine technology and data center operations.
