* The F400 can also be configured with 2 controller nodes, in which case, the cache, host ports, number of
drives and raw capacity would be like those described for the F200.
† Levels, ratios, and capacities all mixable within the same storage server. 1 GB=1,000,000,000 bytes.
‡ A single drive chassis holds up to 16 drives in 3U of space within an EIA-standard rack.
**Japan Green Law statement of compliance: The energy consumption efficiency value has been
calculated per requirements for Category-G Magnetic Disk Drive Units by dividing the power
consumption, measured according to the definition in the Law Concerning the Rational Use of Energy,
by the storage capacity defined in the Energy Conservation Law.
