Broadcom 3ware 9750-8e LSI00243 PCIe 2.0 x8 8-Port External 6Gb/s SATA/SAS Hardware RAID Controller

Basic Parameter Table

Core Product Features

1. High-performance dedicated external-only 3ware hardware RAID controller, large capacity cache chip greatly optimizes random write performance for heavy-load external all-flash JBOD arrays; no internal disk connectors, exclusively built for external expansion enclosures.
2. One SFF-8088 external port supports up to 8 SAS/SATA/SSD drives via external JBOD cabinets; PCIe 2.0 x8 high-speed bus fully satisfies high IO all-flash storage bandwidth demands.
3. Dual available working firmware modes:
   • IR RAID Mode: Full hardware RAID 0/1/5/6/10/50/60 with hardware-level disk redundancy and write cache acceleration, for enterprise database, financial transaction storage that requires RAID fault tolerance.
   • IT Pass-through Mode: Can be reflashed to pure IT firmware, OS independently controls each disk, no RAID layer interception, suitable for high-performance all-SSD external NAS.
4. Oversized white passive heatsink ensures stable 24/7 long-term silent running in rack servers; full-height & low-profile mounting brackets are included.
5. Supports external hard drive hot-swap under both RAID and IT modes, all external storage devices are fully exposed to host operating system.
6. High-spec external expansion RAID/HBA dual-purpose card, higher bandwidth and larger cache than low-end 9280-8e / 9285-8e series, ideal for heavy IO all-flash external storage and high-end large-capacity DIY external JBOD NAS after IT flashing.

Application Scenarios

1. IR RAID deployment: High-load enterprise all-flash storage servers equipped only with external SAS JBOD expansion arrays, no internal hard drives installed.
2. IT flashed deployment: High-end 8-bay all-SSD external ZFS TrueNAS media storage, virtualization heavy IO mass storage backend, enterprise-grade all-flash home lab JBOD storage servers.
3. Not applicable: Storage scenarios requiring CacheVault power-off cache protection.
