* Typical effective capacity is the available capacity after system overhead (including flash media over-provisioning and RAID protection) and after the data reduction benefits of pattern removal, deduplication and compression. This assumes data reduction of up to a multiple of 5 to 1.

† Maximum capacity refers to the effective capacity provisioning limit.

‡ Physical capacity is the available capacity after system overhead, including flash media over-provisioning and RAID protection.
