eShinreal PCIe x8 to SAS/SATA Expansion Card with External SFF-8088 Ports (SAS 3008 Chipset)

1. Enterprise-Grade External SAS3 Connectivity
Dual SFF-8088 external ports (4 lanes per port, total 8x SAS3/SATA lanes)

SAS 3008 controller delivers 12Gbps per lane (backward compatible with 6Gbps SAS2/SATA III)

Supports JBOD/RAID configurations (mode depends on firmware)

2. PCIe 3.0 x8 High-Bandwidth Host Interface
8GB/s full-duplex bandwidth (no bottleneck for multi-drive arrays)

Compatible with PCIe 2.0 slots (at reduced speeds)

Ideal for external storage enclosures (DAS, JBOD)

3. Hardware RAID & IT Mode Flexibility
IR Mode (RAID): Supports RAID 0/1/5/6/10/50/60 + JBOD

IT Mode (HBA): Direct disk passthrough (for ZFS, UnRAID, Ceph)

Optional BBU/supercapacitor for cache protection (RAID models)

4. Enterprise Reliability Features
Hot-plug support (for drive maintenance without downtime)

T10 PI data integrity (end-to-end checksum protection)

S. M. A. R. T. /temperature monitoring via management tools

5. Professional Use Cases
Direct-Attached Storage (DAS) expansions

Backup servers with external drive shelves

Media production (high-speed external storage for 4K/8K workflows)

Disaster recovery setups (quick-swap external arrays)
