Troubleshooting

Problem:Drive ikke detekteret i server

Solutions

→Tjek U.2 backplane power og data connections
→Verify HBA card eller RAID controller kompatibilitet
→Update server firmware og HBA drivers
→Test drive i andet bay - kan være backplane issue
→Check BIOS/UEFI for PCIe lane allocation

Problem:Performance degradation over tid

Solutions

→Check SMART wear leveling count
→Verify ikke thermal throttling (>70°C sustained)
→Run secure erase eller sanitize for factory performance
→Check for firmware updates fra vendor
→Monitor for bad blocks og reallocated sectors
→Verify workload matcher drive type (read vs write intensive)

Problem:Høj latency spikes

Solutions

→Check for concurrent background operations (TRIM, GC)
→Monitor queue depth - undgå over-subscription
→Verify proper PCIe lane allocation (x4 minimum)
→Check for CPU steal eller I/O wait i virtualiseret environment
→Update firmware - kan indeholde latency fixes
