9380-4i4e
Broadcom
The LSI MegaRAID SAS 9380-4i4e (part number LSI00439 / 05-25190-02) is a 12Gb/s SAS and 6Gb/s SATA RAID controller card based on the LSI SAS3108 dual-core RAID-on-Chip processor. Equipped with 4 internal and 4 external SAS ports, the card addresses internal boot storage plus external JBOD expansion within a single PCIe adapter. It targets server builds where hardware-accelerated RAID and mixed internal-external storage topologies are required.
Commercial procurement teams select this controller for database servers, virtualization hosts, and entry-level storage appliances. The split port configuration allows one card to handle both internal OS arrays and external capacity shelves, reducing the total adapter count inside each server chassis.

The LSISAS3108 dual-core RAID-on-Chip processor offloads parity calculation, striping, and rebuild operations from the host CPU. On-board 1 GB of 1866 MHz DDRIII SDRAM serves as write cache and read look-aside buffer. For deployments requiring cache persistence across power loss, an optional CacheVault Flash Module (LSICVM02) can be added to flush cache contents to flash storage.
The host side uses a PCIe 3.0 ×8 edge connector, providing sufficient bandwidth for eight concurrent 12 Gb/s SAS links. The four internal ports accept SFF-8643 connectors for backplane or direct drive attachment, while the four external ports use SFF-8644 connectors for connection to external JBOD enclosures. The MD2 low-profile PCB fits both full-height and 2U low-profile server chassis with the appropriate bracket.
Enterprise customers running virtualized workloads commonly pair the 9380-4i4e with internal SSD arrays for hypervisor boot and VM storage, while using the external ports to attach capacity expansion shelves for backup or cold data tiers. The hardware RAID engine maintains consistent IOPS under heavy random write patterns without consuming additional host CPU cycles.
The controller supports both 12 Gb/s SAS and 6 Gb/s SATA drives simultaneously, allowing mixed-media arrays and gradual drive refresh cycles. It operates under major server operating systems including Windows Server, Linux distributions, and VMware ESXi. Standard MD2 low-profile dimensions ensure compatibility with 2U rack servers and many tower chassis.
When connected to SAS expanders inside external enclosures or backplanes, the controller can address up to 240 total SAS or SATA devices across its eight ports.
No. Cache protection is sold separately as the CacheVault Flash Module (LSICVM02), which uses flash storage and a supercapacitor instead of a traditional battery. The base card ships with 1 GB of volatile DDRIII cache only.
Yes. The card uses an MD2 low-profile form factor measuring 6.6 inches by 2.536 inches, and ships with a low-profile bracket suitable for 2U rack-mount servers.
