What is the HP Praesidium SpeedCard?
The HP Praesidium SpeedCard is a hardware-based security solution
that enables your server’s CPU to sustain maximum performance. It is
designed for applications that demand security yet still need to handle
large client loads. An HP Praesidium SpeedCard is the secure server
performance solution when you experience the following capacity issues:
• Your server is CPU bound (utilization is over 90%) under peak load.
• Your server’s response time is slowing during busy periods, but your
network pipe is not full.
• Your clients are being turned away.
An HP Praesidium SpeedCard dramatically increases your server’s
response time and the number of clients it can support. This is the server
performance solution to help your business grow! The HP Praesidium
SpeedCard easily plugs into your server’s bus and performs the critical
cryptographic functions required by your security system. An HP
Praesidium SpeedCard not only accelerates the lengthy RSA public key
decryption and encryption process, but also relieves the server CPU
bottleneck.
The HP Praesidium SpeedCard also increases the number of clients your
web server can support with security running Secure Sockets Layer
(SSL) transactions. It improves CPU utilization and off-loads your server
to perform other tasks.
The HP Praesidium SpeedCards provide two classes of cryptographic
capabilities:
1. Modular exponentiation functions, including DH, DSA, RSA and raw
modular exponentiation.
2. Random number generation, appropriate for secure key generation.
