Broadcom LSI 9271‑8i PCIe3.0 MegaRAID RAID Controller (Flashable IT-Mode HBA, No CacheVault)

Basic Parameter Table

Core Product Features

1. Enterprise PCIe3.0 RAID controller built on LSISAS2208 chip, native MegaRAID IR firmware supports full advanced hardware RAID levels, on-board cache boosts random write performance for medium enterprise storage arrays, no CacheVault power failure cache protection module.
2. Dual SFF-8087 internal connectors support up to 8 SATA/SAS hard drives inside chassis; PCIe3.0 x8 bus delivers higher bandwidth than PCIe2.0 series adapters.
3. Dual flexible operation modes:
   • IR RAID Mode: Hardware RAID full acceleration with cache memory, built-in disk redundancy protection, fit for regular medium enterprise file and backup storage servers without strict power-off data protection demands.
   • 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 software storage solutions.
4. Fanless passive white heatsink design, stable 24/7 continuous running for rack storage servers; full-height & low-profile mounting brackets are included.
5. Internal hard drive hot-swap available after IT firmware flash, all storage devices directly exposed to host operating system.
6. Cost-effective 8-port SAS2208 PCIe3.0 model, balanced performance and price, mainstream pick for general enterprise RAID deployment and mid-range 8-bay DIY ZFS NAS after IT flashing.

Application Scenarios

1. Native IR RAID deployment: Medium enterprise regular storage servers, backup disk arrays that do not require power-failure cache data protection.
2. IT-flashed HBA deployment: 8-bay mid-range ZFS TrueNAS media storage, virtualization storage backend, cost-effective mass home lab storage servers.
