Core Product Features
- Enterprise PCIe 3.0 RAID adapter powered by LSISAS2208 advanced chipset, native MegaRAID IR firmware supports full advanced hardware RAID levels, onboard cache optimizes random write performance for small compact enterprise storage arrays.
- Single SFF-8087 internal connector supports up to 4 SATA/SAS hard drives inside mini ITX / compact rack chassis; PCIe3.0 x8 bus provides higher bandwidth than PCIe2.0 generation controllers.
- Dual flexible operation modes:
- IR RAID Mode: Full hardware RAID acceleration with cache memory, built-in disk redundancy protection, applicable to compact small enterprise file & backup storage servers without strict power-failure cache protection requirements.
- IT Pass-through Mode (firmware reflash required): Disable onboard RAID logic, operating system independently controls every single disk, perfectly matches software RAID solutions like ZFS RAID-Z, mdadm, unRAID.
- Fanless passive white heatsink design, stable 24/7 non-stop running for compact rack & mini chassis storage servers; full-height & low-profile mounting brackets are included.
- Internal hard drive hot-swap function available after flashing to IT mode, all storage devices are directly exposed to the host operating system.
- Compact 4-port PCIe3.0 flagship model of SAS2208 series, superior signal stability and power efficiency, premium choice for compact 4-bay enterprise hardware RAID storage and mini ITX high-performance DIY NAS after IT flashing.
Application Scenarios
- Native IR RAID deployment: Small enterprise compact 4-drive storage servers, mini backup disk arrays requiring hardware RAID 5/6 data protection.
- IT-flashed HBA deployment: Mini ITX 4-bay ZFS TrueNAS media storage, low-power compact virtualization storage backend, high-end mini home lab storage servers.
