*1 : ­

Physical capacity is calculated based on the assumption that 1TB=1,000GB and 1GB=1,000MB.

  • NVMe SSDs: {15.36TB × (24 drives/CE + 24 drives/DE × 7 DEs)} × 12 CEs = 35,389.44TB » 35,389TB

  • SAS SSDs: (30.72TB × 24 drives/DE × 15 DEs) × 12 CEs = 132,710.4TB » 132,710TB

  • SAS disks: (2.4TB × 24 disks/DE × 15 DEs) × 12 CEs = 10,368TB

  • Nearline SAS disks: (18TB × 12 disks/DE × 15 DEs) × 12 CEs = 38,880TB

If the integer value of the calculated maximum physical capacity is three digits or more, it is rounded off to the ones place.
*2 : 

Extreme Cache Pools use the NVMe SSDs (3.2TB) that are installed in the controller enclosures or NVMe type drive enclosures as the cache. Up to four drives can be installed for the Extreme Cache Pools per controller and the maximum capacity of the Extreme Cache Pools in each controller is 12.8TB.
*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 : 

If there are less than two controller enclosures installed, one or more drive enclosures are required.
*5 : 

Up to seven drive enclosures can be installed in each controller enclosure.
*6 : 

Up to 15 drive enclosures can be installed in each controller enclosure.
*7 : 

The number of drives when a mix of NVMe SSDs and SAS drives are installed. The number of drives when only NVMe SSDs are installed is 4 to 2,304. The number of drives when only SAS drives are installed is 4 to 4,320.

*8 : 

NVMe SSDs (3.2TB) can be used as drives for configuring Extreme Cache Pools.
