Do the SSL-VPN appliances have hardware-based SSL acceleration onboard?

Answer: All models except the SRA 1200 have hardware-based SSL accelerators onboard -
even the SSL-VPN 200 model. The SRA 1200 does not have a hardware-based SSL
accelerator processor.
What are the main differences between the discontinued SonicWALL SSL-RX
3.
Accelerator from that of the SSL-VPN 200, 2000 and 4000 appliances?
Answer: The discontinued SSL-RX Accelerator was a purpose-built appliance used to offload
cryptographic processes from burdened servers. The SSL-VPN 200, 2000 & 4000 are designed
to provide easy-to-use, lightweight, clientless access to internal network resources using a Web
browser. The SSL-VPN 200 appliances cannot be used as an SSL Accelerator. The SSL-VPN
2000 & 4000, using Web Application Offloading in 3.5 can now function as an SSL Accelerator.
What operating system do the SonicWALL SSL-VPN appliances run?
4.
Answer: The SonicWALL SSL-VPN appliance runs SonicWALL's own hardened Linux
distribution.
Can I put multiple SonicWALL SSL-VPN appliances behind a load-balancer?
5.
Answer: Yes, this should work fine as long as the load-balancer or content-switch is capable
of tracking sessions based upon SSL Session ID persistence, or cookie-based persistence.
