vSphere Installation and Setup Table 2-1. Recommendations for Enhanced Performance System Element Recommendation RAM ESXi hosts require more RAM than typical servers. Provide at least 8GB of RAM to take full advantage of ESXi features and run virtual machines in typical production environments. An ESXi host must have sufficient RAM to run concurrent virtual machines. The following examples are provided to help you calculate the RAM required by the virtual machines running on the ESXi host. Operating four virtual machines with Red Hat Enterprise Linux or Windows XP requires at least 3GB of RAM for baseline performance. This figure includes approximately 1024MB for the virtual machines, 256MB minimum for each operating system as recommended by vendors. Running these four virtual machines with 512MB RAM requires that the ESXi host have approximately 4GB RAM, which includes 2048MB for the virtual machines. These calculations do not take into account possible memory savings from using variable overhead memory for each virtual machine. See vSphere Resource Management . Dedicated Fast Ethernet adapters for virtual machines Place the management network and virtual machine networks on different physical network cards. Dedicated Gigabit Ethernet cards for virtual machines, such as Intel PRO 1000 adapters, improve throughput to virtual machines with high network traffic. Disk location Place all data that your virtual machines use on physical disks allocated specifically to virtual machines. Performance is better when you do not place your virtual machines on the disk containing the ESXi boot image. Use physical disks that are large enough to hold disk images that all the virtual machines use. VMFS5 partitioning The ESXi installer creates the initial VMFS volumes on the first blank local disk found. To add disks or modify the original configuration, use the vSphere Client. This practice ensures that the starting sectors of partitions are 64K-aligned, which improves storage performance. NOTE For SAS-only environments, the installer might not format the disks. For some SAS disks, it is not possible to identify whether the disks are local or remote. After the installation, you can use the vSphere Client to set up VMFS. Processors Faster processors improve ESXi performance. For certain workloads, larger caches improve ESXi performance. Hardware compatibility Use devices in your server that are supported by ESXi 5.1 drivers. See the Hardware Compatibility Guide at http://www.vmware.com/resources/compatibility. ESXi Support for 64-Bit Guest Operating Systems ESXi offers support for several 64-bit guest operating systems. For a complete list of operating systems supported for ESXi, see the VMware Compatibiity Guide at http://www.vmware.com/resources/compatibility/search.php. Hosts running virtual machines with 64-bit guest operating systems have the following hardware requirements: n For AMD Opteron-based systems, the processors must be Opteron Rev E or later. 30 VMware, Inc.
n For Intel Xeon-based systems, the processors must include support for Intel Virtualization Technology (VT). Many servers that include CPUs with VT support might have VT disabled by default, so you must enable VT manually. If your CPUs support VT ,but you do not see this option in the BIOS, contact your vendor to request a BIOS version that lets you enable VT support. To determine whether your server has 64-bit VMware support, you can download the CPU Identification Utility from the VMware Web site. Hardware Requirements for vCenter Server, vCenter Single Sign On, vSphere Client, and vSphere Web Client The vCenter Server system is a physical machine or virtual machine with access to a supported database. The vCenter Server system must meet specific requirements. The vCenter Server machines must meet the hardware requirements. vCenter Single Sign On, Inventory Service and vCenter Server Hardware Requirements You can install vCenter Single Sign On, Inventory Service, and vCenter Server on the same host machine (as with vCenter Simple Install) or on different machines. Table 2-2 and Table 2-3 list the hardware requirements for Single Sign On and Inventory Service, running on separate host machines. If you install vCenter Single Sign On, vCenter Inventory Service, and vCenter Server on the same host machine, the Single Sign On and Inventory Service memory and disk storage requirements are in addition to the requirements for vCenter Server. See Table 2-4. Table 2-2. Minimum Hardware Requirements for vCenter Single Sign On, Running on a Separate Host Machine from vCenter Server vCenter Single Sign On Hardware Requirement Processor Intel or AMD x64 processor with two or more logical cores, each with a speed of 2GHz. Memory 3GB. Memory requirements might be higher if the vCenter Single Sign On database runs on the same host machine. If vCenter Single Sign On runs on the same host machine as vCenter Server, see Table 2-4. Disk storage 2GB. Disk requirements might be higher if the vCenter Single Sign On database runs on the same host machine. Network speed 1Gbps Table 2-3. Minimum Hardware Requirements for vCenter Inventory Service, Running on a Separate Host Machine from vCenter Server vCenter Inventory Service Hardware Requirement Processor Intel or AMD x64 processor with two or more logical cores, each with a speed of 2GHz. Memory 3GB. If vCenter Inventory Service runs on the same host machine as vCenter Server, see Table 2-4. Disk storage At least 60GB for medium- to large-sized inventories (more than 100 hosts or 1000 virtual machines). Network speed 1Gbps Chapter 2 System Requirements If vCenter Inventory Service runs on the same host machine as vCenter Server, see Table 2-4. VMware, Inc. 31
