*1: Physical capacity is calculated based on the assumption that 1TB=1,000GB and 1GB=1,000MB.
*2: Extreme Cache uses the PFMs that are installed in the controller enclosures as the cache. The value indicates the maximum capacity
when 3.2TB PFMs are installed in the controller enclosure. The maximum capacity when 1.6TB PFMs are installed is 25.6TB (12.8TB for
each controller enclosure).
*3: Different types of drive enclosures can be installed together in an ETERNUS DX. When different types of drive enclosures are installed
together, the maximum number of installable drive enclosures depends on which drive enclosure type combinations are used.
*4: Up to 47 drive enclosures can be installed in each controller enclosure.
*5: Up to 16 drive enclosures can be installed in each controller enclosure.
*6: The number of drives when only 2.5" drives are installed. The number of drives when only 3.5" drives are installed is 2 to 2,256.
*7: For details, refer to "
■ Drives" (page 272) in "Component" (page 270).
*8: The drives are FIPS-compliant.
