• If the system has only a single Metadata module, you must add
a second Metadata module when adding the fifth 2TB Array
module.
• The system’s total capacity is limited by the system maximum
usable capacity of 320TB (10 2TB Array modules plus 6 2TB
Expansion modules).
• Up to 9 2TB Array modules will be in the base rack with a 10th
2TB Array module and up to 6 2TB Expansion modules in the
expansion rack.
Note: The un-racked 2TB configurations have up to 8 Array
modules in the base rack and 2 Array modules in the
expansion rack.
• Adding Modules with 3TB drives - The capacity expansion strategy
is to add one 3TB Array module first and then begin adding 3TB
Expansion modules.
• If the system has only a single Metadata module, you must add
a second Metadata module when adding the first 3TB Array
module.
• A second 3TB Array module is required for 6 or more 3TB
Expansion modules.
• The system’s total capacity is limited by the system maximum
usable capacity of 330TB.
• An expansion rack is required if the rack space required for all
Array modules and Expansion Modules (2TB or 3TB) exceeds 27
U.
Caution: After you add a 3TB Array module to a 2TB base
system, all future capacity expansion for the system
must
use 3TB Array and Expansion modules only.
Note: To add a 3TB Array module or Expansion modules to a 2TB
base system, the DXi8500 must be running DXi 2.1.2_85
Software or higher.
