Rainbow is too expensive, so is nCipher, and any of the front end devices.
Our OS is W2k ADVServer, SP2 -with schannel.dll fix.
Here are our finalists:
Atalla's AXL300 Card sells on the street for $1495. We tested it and were able to manage 285cps on a 2x833Mhz, cpu was about 67%. Compaq says they scale linearally, up to 8 in a box (if you had the slots, and the bus didn't bottleneck). If you have an app that supports CRT, they claim you could double your cps.
Broadcom's solution comes in at less than $1000. It supports up to 600cps and with the same server config as above, managed around 560cps, cpu at 85%.

Well, for the short term you don't have a lot of choices.
Rainbow is by far the most popular and widely used. There is also
Attala that Compaq OEMs and, nCipher, and Phobos (they make the load balancer
of the future....in joke...)
Right now most people are using off the shelf rainbow cards. There are some
network gear vendors out there doing it with broadcom chipsets (which I believe
were BlueSteel before they were aquired), many people are starting to utilize
geneeral VPN accelerators with SSL (for doing DeS stuff).
There are also several stealth startups which are doing some pretty cool
stuff with SSL accelerators in excess of what is available today.
I would venture to say that the people making their own SSL chipsets I can
count on two hands, but It's still a lot better than just 1. Even with
what's existing today you have choices, but the best one so far isn't all
that great. Be patient there's more stuff coming!

An interesting thought. I'm not saying that the entire internet will become
crypto. But that it will be so easy to do so (atleast with commercial
hardware) the big sites would just do it by default.
But from what I have seen there are so many implementations of SSL (both in
hardware and software) no one is going to have a controlling stake in it
in the same way people were paranoid about the skipjack stuff.
In all reality, we know that SSL doesn't really buy us much. People will
break into the database if they want all the info, not sniff the traffic
(atleast on the server side). It can be broken, and sometimes with not much
computing effort. But it makes people feel better. And if a wide
acceptance of SSL happens it will definately benefit the client side so you
don't have some disgruntled network admin sniffing corp traffic and stealing
all the execs logins to their online brokerage and bank accounts.
Let me leave you with this interesting thought on SSL accelerators. From our
testing we can get 100 conn/s out of a PIII-800 running mod_ssl. Obviously
it maxes out the CPU at that point. Let's just say for example I wanted
200 conn/s of SSL. That PIII-800 box costs me about 1.5-3K each. How much does
1 cryptoswift 200 cost? How much does it cost when F5 sells it to you? Or
Intel, or alteon? (plus I still need to buy the server).
