
Load balancers for very large deployments (more than 5,000 clients)
Table 2‐1 lists recommendations for the number of clients supported based on the hardware you are using. The
figures for recommended clients reserve some server processing power so that interactive clients receive
responses in a timely fashion and the server satisfies increases in demand.

2‐GHz AMD 2‐way server (Opteron 280, 4GB RAM)
2‐GHz Intel 2‐way desktop machine (4GB RAM)

Database Throughput and Scalability

For production deployments, VMware recommends that you use Oracle, MS‐SQL, or Postgres as your
database platform.
More than 95 percent of the storage space that an ACE Management Server requires is used to log event
information, which is an audit trail of all transactions performed through ACE Management Server. Table
lists recommended database sizes based on the number of clients being served.
The figures in the table are based on a 90‐day database archival period. Back up the database records every 90
days and keep event logs for 90 days. You can configure ACE Management Server to purge event logs every
90 days.

The authentication event generates most of the data because an event is generated every time someone
attempts to authenticate to ACE Management Server. You can configure ACE Management Server to log less
event information. See "Logging Events" on page 36.

LDAP Throughput

ACE Management Server can communicate with your Active Directory domain controller to authenticate user
credentials. Your domain controller infrastructure handles the LDAP traffic required to support the number
of clients that you anticipate.
Integrating with Active Directory through LDAP is implemented differently in the Windows ACE
Management Server than in the Linux‐based ACE Management Server. The Windows ACE Management
Server uses the WinLDAP library bundled with your Windows operating system. The Linux ACE
Management Server uses a third‐party Kerberos Library and OpenSSL. VMware internal testing results
indicate that the Windows implementation provides better performance than Linux.
