SHA-256 accelerated via GPU
Posted: Tue Jul 03, 2012 2:34 am
Greetings,
I just starting testing out StarWind with deduplication, it seems to be pretty awesome. It seems that under heavy load it requires a lot of CPU power, which seems like it would be mostly doing SHA-256 operations.
GPU's are awesome for these type of encryption operations.
Example from the bitcoin hardware wiki
A top of the line intel can get about 15mhashes per second. Compared to a ATI 6970 with 400mhashes per second.
If the hashes could be offloaded to the GPU it seems like you could increase the IO through the rough.
Any thoughts?
I am planning out a Windows 2008R2 system with 8 SSD drives in a raid 10, but I think I would be maxing out the CPUs because I hit the I/O or network wall.
