The invention concerns a disk cache for secure writing comprising means (62) for standby power supply for a specific time interval, to a computer system powered by two main electric power supply elements (60, 61) and including, at least one hard disk unit (1a, 1b, 1c), a host system (3), all disk units (1a, 1b, 1c) being connected by a bus (2) to a connection (30) of the host system (3) (host bus adapter), and means (50) for monitoring at least the means (62) supplying electric power and the main power supply elements (60, 61). The invention is characterised in that the monitoring means (50) are connected to the interface (2) and can be queried by the host system (3) query means (31) so that the latter can validate or not the write disk cache function in the write commands addressed to the disk units (1a, 1b, 1c) on the basis of data acquired by the monitoring means (50). |
