Core Product Features
- External-only enterprise RAID controller built on SAS2108 chipset, native MegaRAID IR firmware supports full advanced hardware RAID levels, onboard cache optimizes random write performance for external JBOD disk expansion systems. No internal drive connectors, designed purely for external storage enclosures.
- Single SFF-8088 external connector supports up to 8 SATA/SAS hard drives via external expansion cabinets; PCIe2.0 x8 bus delivers stable bandwidth for multi-disk external arrays.
- Dual flexible operation modes:
- IR RAID Mode: Full hardware RAID acceleration with cache memory, built-in disk redundancy protection, suitable for enterprise storage servers that only use external JBOD disk arrays without internal hard drive bays.
- IT Pass-through Mode (firmware reflash required): Disable onboard RAID logic, OS independently controls every single disk, fully compatible with ZFS RAID-Z, mdadm, unRAID external mass storage solutions.
- Fanless passive white fin heatsink design, stable 24/7 continuous running for rack storage servers; full-height & low-profile mounting brackets included.
- External hard drive hot-swap available after IT firmware flash, all external storage devices directly exposed to host operating system.
- Cost-effective dedicated external expansion RAID/HBA card, the optimal pick for servers with empty internal bays that only rely on external JBOD enclosures for capacity expansion, widely used for enterprise centralized expansion storage and external large-capacity DIY NAS.
Application Scenarios
- Native IR RAID deployment: Enterprise storage servers equipped exclusively with external SAS JBOD expansion disk arrays, no internal hard drives installed.
- IT-flashed HBA deployment: Servers that use only external expansion enclosures to build 8-bay ZFS TrueNAS media storage, virtualization external mass storage backend, home lab large-capacity external JBOD NAS.
