The IBM ESMR 3.72 TB Mainstream SAS SSD offers a 6 Gb/s SAS interface and 4k (4224-byte) sector formatting, optimized for IBM i on Power Systems (e.g., 9009, 8286). Mounted on a 2.5-inch SFF-3 carrier, it fits system unit SAS bays, delivering superior performance over HDDs with a 1 DWPD rating and 6799 TB total bytes written over 5 years. It supports RAID 0, 1, 5, 6, 10, and Easy Tier arrays when paired with PCIe3 SAS RAID adapters (e.g., EJ0L, EJ14), but cannot mix with 5xx-byte drives in arrays. The SSD Mainstream Fuel Gauge monitors write life, available via IBM i. Available refurbished, it provides a cost-effective storage solution with a 60-day warranty.
System Compatibility
The ESMR SSD requires SFF-3 bays and PCIe3 SAS adapters for optimal IBM i storage performance.
- Supported Systems:
