| |
I'm in the process of looking for a PCI NVRAM card that could be used with Linux, and I haven't been very successful thus far. The only company I've found with such a card is unwilling to sell it except to their primary customer.
There are an entire range of applications for which such a card could be used in Linux: filesystem logging, fast NFS write acks, kernel debugging (logging to memory instead of disk), block devices, etc. I'm aware that some of the more recent RAID controllers include NVRAM for faster writes, but they doesn't provide the same flexibility as a general-purpose NVRAM card (and they are really expensive: one or two thousand dollars).
For this task, flash memory is not an option, since it is only designed for a relatively small number of writes, and it is slow. What you probably want is either battery-backed SDRAM or SRAM. 64MB is a good amount, but I'd settle for less (especially if a version providing more NVRAM was forthcoming).
So, is anyone aware of such a card available on the general market?
