PRESTO(4)              BSD Programmer's Manual (SPARC)               PRESTO(4)

NAME

     presto - Prestoserve battery-backed memory

SYNOPSIS

     presto* at sbus? slot ? offset ?

DESCRIPTION

     The Legato Prestoserve NVRAM cards used to be part of the "NFS
     accelerator" product, which used the cards memory as an NFS-dedicated
     cache, increasing performance of NFS servers exporting filesystem as NFS
     protocol, version 2.

     The presto driver does not attempt to achieve such a behaviour, which is
     questionable with the advent of NFS protocol, version 3.

     Instead, it will provide direct access to the NVRAM, as a block device.

FILES

     /dev/prestoup      block mode Prestoserve card number u, partition p
