Product Description
IBM ES8Z 931GB Mainstream SAS 4k SFF-2 SSD for IBM i (00LY553)
The IBM ES8Z is a cost-effective Mainstream SSD designed for IBM Power Systems running IBM i. It delivers 931 GB of storage with solid performance for general-purpose IBM i workloads such as databases, virtualization, and application environments when installed in expansion drawers.
Product Description
The IBM ES8Z (feature code ES8Z, part number 00LY553, CCIN 5B29) is a 2.5-inch SFF-2 Mainstream SAS SSD formatted with 4224-byte (4k) sectors for IBM i. It provides a good balance of capacity, performance, and cost for read-intensive and mixed workloads. The drive is mounted on an SFF-2 carrier/tray and is designed for installation in EXP24S and EXP24SX expansion drawers. It is an excellent choice for IBM i environments that need higher capacity at a more affordable price point than high-endurance Enterprise SSDs.
