IBM EC7A PCIe4 x8 NVMe 1.6 TB Flash Adapter LP for AIX Linux Power 9 power 10The PCIe4 x8 NVMe 1.6 TB SSD NVMe adapter is a Peripheral Component Interconnect Express (PCIe) generation 4 (Gen4) x8 adapter. The adapter can be used in either a x8 or x16 PCIe (Gen4) slot in the system and uses Non-Volatile Memory Express (NVMe). NVMe is a high-performance software interface that can read or write flash memory. Compared to a Serial-attached SCSI (SAS) or Serial Advanced Technology Attachment (SATA) SSD, the NVMe adapter provides more read or write, input or output operations per second (IOPS) and larger throughput (GB/sec). The type of workload has a great impact on the maximum write capacity. If a high percentage of more sequentially oriented write operations is used instead of random write operations, the maximum write capacity will be large. To extend the life of the NVMe device, the application that is using the device must convert small random write operations to larger sequential write operations. The write operations that exceeds the maximum write capacity of the adapter continue to operate for some time, but the performance will be slow. The life of the device is not affected depending on whether the application uses sequential or random read operations from the device. A Predictive Failure Analysis message is displayed when the adapter that is enabled by the system administrator must be replaced
