SRA Sizing
76 Portal Server 6 2005Q1 • Deployment Planning Guide
• 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.
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.
NOTE You do not need to specify the Page Configuration and Scalability
options if you are using trial deployment numbers.
