Instructions

En TRIM-kommando, også kaldet TRIM i ATA-kommandosættet og UNMAP i SCSI-kommandosættet, gør et operativsystem i stand til at underrette et solid-state-drev (SSD) om, hvilke datablokke der ikke længere anses for at være i brug og kan slettes internt. Beskæring gør det muligt for SSD'en at håndtere affaldsindsamling mere effektivt, hvilket ellers ville bremse fremtidige skriveoperationer til de involverede blokke.

TRIM til SSD'er er angivet som en funktion i PERC-familien. Der har været rapporter, hvor TRIM kun understøttes i HBA-tilstand og ikke i RAID-tilstand.

 

Fra og med januar 2017 er support af TRIM-kommandoen ikke implementeret i de fleste hardwarebaserede RAID-teknologier. Ofte omfatter RAID-softwareimplementeringer ikke understøttelse af TRIM. Desuden understøttes TRIM-funktionen kun på pass-through-SSD'er. Du finder ud af, hvordan du foretager TRIM på pass-through-SSD'er, i Brugervejledning til S130.
