Novell Doc: Identity Audit Guide - Hardware Requirements

2.1 Hardware Requirements

Novell Identity Audit is supported on 64-bits intel Xeon* and AMD Opteron* hardware. It is not supported on Itanium* hardware. Novell recommends the following hardware for a production system that holds 90 days of online data:

1x Quad Core (x86-64)
16 GB RAM
1.5 TB usable disk space - 3x 500GB (3 usable), 10K RPM drives in a hardware RAID configuration
- Approximately 2/3 of the usable disk space is used for database files
- Approximately 1/3 of the usable disk space is used for the search index and temp files
- A small amount of storage is available for archived data that has been removed from the database, but Novell recommends that you move archived data files from the Identity Audit server to a long-term storage location.

Table 2-1 Performance

Metric	Value	Description
Events per second (eps) - steady state	100	Average event rate during normal operations
Events per second (eps) - peak	500	Peak event rate during a spike (up to 10 minutes)
Events per second (eps) - peak per application	300	Peak event rate from each type of Novell application Event rates are typically low (less than 15 eps) for Identity Manager, SecureLogin, SecretStore®, and NMAS™) Event rates can be very high from eDirectory™ and Access Manager. Event filtering should be implemented to ensure a manageable rate. Even during an event spike, no one application can send more than this many events per second.
Online data	90 days or 750 million events	Amount of data Identity Audit can store at a steady state rate of approximately 100 eps, with the recommended storage
