Regarding my earlier posts on HSMs (here and here), some colleagues from a sister institution pointed out to me today new information on the Sun Crypto Accelerator 6000s. These Sun cards are actually quite popular with people in need of SSL/TLS acceleration, but they are also coming into their own as FIPS-3 compliant HSMs for use with DNSSEC primarily because OpenDNSSEC works with them... and their historical cost has been in the $1,500 range.
That was until Oracle figured out that their product was popular, and the new price on the "Oracle" branded Sun Crypto Accelerator 6000s is $9,950. That would make them more expensive than the FIPS-4 compliant IBM 4764s. I, btw, have used these cards and don't believe they are worth what Oracle is charging.
