00AR104 IBM PCI-E Controller Storwize Node Canister

PCI-E Connectivity: The PCI-E Controller is designed with high-speed PCI-Express connectivity, which allows for fast data transfer rates and improved storage performance.

Cache: The controller includes a large cache capacity that can help to improve the performance of data access. The cache provides a temporary storage area for frequently accessed data, which can be quickly retrieved from the cache instead of the disk drives, resulting in improved performance.

Storage Tiering: The controller supports storage tiering, which allows data to be automatically moved between different types of storage, such as fast and slow storage, based on the data’s access patterns. This helps to ensure that frequently accessed data is stored on fast storage, which can improve the performance of data access.
