| Maximum throughput | n/a |
| Latency | n/a |
| Conditions | Per-HA-pair and per-cluster raw/effective capacity, drive counts, power and port maxima from the ASA datasheet (DS-4254) and www.netapp.com/asa; memory, PCIe slots and port speeds from the docs key-specs page. Cluster limit 6 nodes (3 HA pairs), SAN-only. Note: the docs key-specs page lists 0.7344 PB raw per HA pair and 2.2 PB per cluster. raw_tb_min is the smallest per-cluster raw capacity on the product page. Up to 144 SSDs per cluster (product page); effective 6.26 PB per HA pair. power_w is the datasheet median. The datasheet prints the per-HA-pair raw figure as '1.47 TB'; 1.47 PB is used, consistent with its 4.42 PB three-HA-pair cluster figure. |
