What is hardware RAID and how does it protect my dedicated server data?
Hardware RAID uses a dedicated RAID controller card (MegaRAID, LSI, HPE Smart Array) to manage disk redundancy independently of the OS — faster and more reliable than software RAID. RAID 1 (mirroring): 2 identical disks, all data written to both simultaneously. If one disk fails, server continues running from the other. RAID 10: 4+ disks, combining RAID 1 mirroring with RAID 0 striping — both redundancy and performance. RAID 5: 3+ disks with parity — can survive one disk failure. RAID 6: 4+ disks with double parity — survives two simultaneous disk failures. Connect Quest AMD EPYC dedicated servers include hardware RAID controllers with battery-backed cache. Monitor RAID health: megacli -LDInfo -Lall -aAll or ssacli ctrl slot=0 ld all show. Configure RAID via BIOS during setup or request Connect Quest to configure at provisioning.
