Brand: LSI Logic (a legendary name in enterprise storage, later acquired by Avago/Broadcom)

Model: MegaRAID SCSI 320-0Interface Slot: 64-bit PCI-X / PCI (The long, legacy server slot that looks like an extended standard PCI slot).Speed Capability: Ultra320 SCSI, supporting blistering transfer rates for its time up to 320 MB/s.💾 What Exactly Does It Do?This is a Zero-Channel RAID (ZCR) Adapter. Instead of carrying its own expensive SCSI ports directly on the card, it acts as a "brain upgrade" for a server motherboard.When plugged in, it takes control of the motherboard's basic, built-in onboard SCSI chip and transforms it into an advanced, hardware-driven RAID controller. This allows the server to combine multiple hard drives together into arrays for data redundancy and performance via RAID levels 0, 1, 5, 10, and 50. If one hard drive physically fails, the server keeps running without losing data.
