Storage Pools

В Storage Pools дисков сколько угодно.

RAID GROUP - 16 дисков.

Storage Tiering - разнос данных на разные диски (по скорости SSD или SAS) для быстрого доступа. Сначала идет анализ и в зависимости от результатов блоки разносятся на диски для быстрого доступа.

Auto-Tier — Sets the initial data placement to Optimized Pool and then relocates the LUNs data based on the LUNs performance statistics and the auto-tiering algorithm.

Highest Available Tier — Sets the preferred tier for initial data placement and data relocation to the highest performing disk drives with available space.

Lowest Available Tier — Sets the preferred tier for initial data placement and data relocation to the most cost effective disk drives with available space.

Initial Data Placement - Displays tier setting that corresponds to the selection in the Tiering Policy drop-down list box.

Data Movement - Displays whether or not data is dynamically moved between storage tiers in the pool.
