Sun Microsystems 2005Q1 manual SRA Gateway and SSL Hardware Accelerators, Scalability

SRA Sizing

•Regular-JSP. Describes a configuration of two tabs with seven channels each.

•Heavy—JSP. Describes a configuration of three tabs with seventeen channels each.

Scalability

You can choose between one, two, and four CPUs per Gateway instance. The number of CPUs bound to a Gateway instance determines the number of Gateway instances required for the deployment.

Secure Portal Pilot Measured Numbers

If you have numbers from a pilot of the SRA portal, you can use these numbers in the Gateway sizing tool to arrive at more accurate results. You would fill in the following:

•Measured CPU Performance. The values used to help calculate the number of Gateway instances include:

❍

❍

Initial Portal Desktop Display, hits per second per CPU

Portal Desktop Reloads, hits per second per CPU

•Netlet Applications Block Size. This value specifies the Netlet application byte size. The Netlet dynamically determines the block size based on the application that is used. Block size determined by Netlet for a Telnet is based on the amount of data transferred.

NOTE You do not need to specify the Page Configuration and Scalability options if you are using trial deployment numbers.

SRA Gateway and SSL Hardware Accelerators

SSL-intensive servers, such as the SRA Gateway, require large amounts of processing power to perform the encryption required for each secure transaction. Using a hardware accelerator in the Gateway speeds up the execution of cryptographic algorithms, thereby increasing the performance speed.

The Sun Crypto Accelerator 1000 board is a short PCI board that functions as a cryptographic co-processor to accelerate public key and symmetric cryptography. This product has no external interfaces. The board communicates with the host through the internal PCI bus interface. The purpose of this board is to accelerate a variety of computationally intensive cryptographic algorithms for security protocols in e-commerce applications.
