Summary of Capacity Plan for Acme Corporation

In the preceding sections, we have described various components involved in capacity planning and have also shown how each of them would apply to an Oracle Internet Directory deployment at a hypothetical company named Acme Corporation. In this section we give a quick summary of all of the recommendations made. Following were the initial assumptions:

• Overall directory size: 3,200,000 entries (3.2 million)

• Number of users: 40,000

• Type of application: IMAP messaging

• Peak search rate: 750 searches/sec at concurrency of 500 clients

Based on these requirements and further assumptions, we developed the following recommendations:

• Disk space: 5 GB to 8 GB

• Memory: 2 GB

• Network: 100 Base-T

• CPU: something that has a SPECint_rate95 of at least 360.

Several simplifying assumptions were made so that the sizing calculations could be more intuitive.
