vReplicator v2.5 Chapter 2 Installation 27

VMware ESX Server Requirements

User Accounts and Passwords

For each replication source and destination VM, you must use a login with appropriate

permissions. vReplicator requires the use of root, non-root, and system administrator

(SA) IDs and non-root and SA passwords. This section contains information specific to

vReplicator password requirements. For additional information, see the General

Password Security Guidelines section at the end of this chapter.

Switch User/Root Access

vReplicator requires root access. For security reasons, many ESX Servers are configured

so that a root user cannot log in directly from another computer. To gain root access,

vReplicator must connect with a non-root user ID and then switch user (su) to the root

account. For the non-root ID and password, it is best to use the same ID and password

that you selected for VC.

System Administrator Access

vReplicator also requires SA access; for example, when you install a new instance of MS

SQL Express 2005. The SA password must meet SQL Server password policy

requirements. In general, SA passwords should be complex but memorable. The

passwords should be written down and adequately protected, but accessible to those who

need them.

Password Security Setting Policy

Weak passwords compromise system security. The MS Windows security setting policy

has been enabled and configured for vReplicator passwords. When you create and update

passwords in vReplicator, follow as many of these guidelines as your environment

allows:

• A password should not include a significant portion of a user or account name.

• Each password should be at least six characters long.

• Passwords should contain characters from several of these categories:

-Uppercase letters in English (A-Z)

-Lowercase letters in English (a-z)

-Digits 0-9

-Non-alphabetic characters (for example, $, !, #, %)

Source

These are the requirements for the source machine:

• You do not need to complete any installations on the source VMFS.

• The source VMFS must be formatted for ESX 3.
