Plan, Install and Upgrade VMware ESX/ESXi
Install VMware ESX/ESXi on local storage
Minimum Hardware Requirements
- 64bit CPU (AMD Opteron, Intel Xenon [inc Nahalem])
- CPU Virtualisation features required to support 64bit VM's
- 2GB RAM
- 1+ NIC
- SCSI, Fibre Channel or Internal RAID controller
- LUN, SAS or SATA (SATA must be connected through a SAS controller)
Notes
- ESX's hardware clock should be set to UTC
- IPv6 not supported during installation
ESXi Specifics
- All blank internal disks are formatted with VMFS (except 4GB VFAT scratch/swap partition, used for vm-support dumps)
- Direct Console is used to
- Configure host defaults
- Set-up administrator access
- Troubleshoot
- If no DHCP found during install, default 169.254.0.0 / 16 address assigned
vSphere Editions
| Edition | Features |
|---|---|
| Standard | 6 cores/CPU, 4way vSMP, 256GB/ESX, Update Manager, HA |
| Advanced | 12 cores/CPU, Hot Add, FT, vShield, VMotion |
| Enterprise | 6 cores/CPU, Storage vMotion, DRS |
| Enterprise Plus | 12 cores/CPU, 8way vSMP, maxGB/ESX, vNetwork Distributed Switch, Host Profiles, 3rd Party Multipathing |
Upgrade VMware ESX/ESXi
Pre-Upgrade Backups
- Backup ESX Host Config
- Back up the files in the
/etc/passwd,/etc/groups,/etc/shadow, and/etc/gshadowdirectories (shadow dir's may not exist). - Backup any custom scripts
- Backup any
.vmxfiles - Backup any local images etc on local VMFS
- Back up the files in the
- Backup ESXi Host Config
- Use vSphere CLI to run
vicfg-cfgbackup --server <ESXi-host-ip> --portnumber <port_number> --protocol <protocol_type> --username username --password <password> -s <backup-filename>
- Use vSphere CLI to run
- VM backup
- Snapshot before upgrade

Minimum Requirements
- 2x CPU's (2GHz)
- 3GB RAM
