Nortel Networks 7400 - Manual (Page 91)

Key Points
Scalability. Resilience. Manageability. Performance.
These age old adages are at the cornerstone of the
Alteon SSL Accelerator (ASA). Scaling to an excess of
150 000 key exchanges per second in a single SSL
offload farm provides sufficient growth for even the
busiest sites.
The ability to cluster the Accelerator not only allows
for rapid fail over it also allows for unparalled
management as all configurations and certificates
are installed once through a common interface and
automatically copied, using encryption, to all other
devices thus providing a single point of
management.
All non SSL traffic is not impacted as this device sits
out of the data path allowing only the SSL session to
be forwarded to the Accelerator for processing thus
increasing throughput of non secure traffic.
Features and Benefits
• The Alteon SSL Accelerator (ASA) can process SSL
transactions 5 to 250 times faster than an HTTPS
server
• A cluster of Accelerators can process up to 150,000
SSL sessions per second on a single Content
Switch
• Centralised, advanced key and certificate
management saves administrative costs and
maintenance hassles
• Automatic import of keys generated by Apache,
Stronghold, OpenSSL, IIS 4.0, Weblogic and PKCS12
• Scalable up to 256 hot swappable SSL Accelerators
per Content Switch for performance and
redundancy
• Supports multiple virtual SSL servers in active-
standby mode for resilient SSL services
• Content Intelligent Switching services for secure
SSL sessions
• HTTP application level knowledge which enables
functions like header add/remove and redirection
• Maintains session context between HTTP
and HTTPS
• Processes SMTP-S, POP3-S and IMAP-S secure
messaging protocols
• Shopping-cart persistence without server
reconfiguration or waste of VIP addresses
• SSH secure management protocol and
SNMP support
• Supports SSL v2.0, SSL v3.0 and TLS v1.0
• Easy import of keys generated by Netscape Server
via a conversion utility
• 10/100 Mbps copper or 1,000 Mbps fibre link from
SSL Accelerator to Content Switch
• Attach to Content Switch directly or across a local
broadcast domain
• Rack-mountable 1U high unit
