System component description

Overview
When calculating the number of drives for your VNXe3100 platform, the 2U DPE is
included in the total drive slot quantity of from 96 to 99 drives in a dual SP system. If the
total drive slot quantity exceeds from 96 to 99, you will not be able to add another DAE.
When calculating the number of drives for your VNXe3100 platform, the 2U DPE is
included in the total drive slot quantity of from 48 to 49 drives in a single SP system. If the
total drive slot quantity exceeds from 48 to 49, you will not be able to add another 2U DAE.
DPE and DAE configuration rules
Table 16 and Table 17 provide a matrix describing what types and how many 2U DAEs can
be used in either a dual SP VNXe3100 platform or in a single SP VNXe3100 platform.
As shown in each table, the first column shows the number 12 (Table 16), which refers to
the 2U, 12 (3.5-inch) disk drive 2U DPE. Across the top of each matrix, the number of DAEs
(DAE1, DAE2, and so on up to DAE7) are listed. Within the body of the matrix (Table 16 or
Table 17), the number 12 refers to the 2U, 12 (3.5-inch) disk drive DAE and the number 25
refers to the 2U, 25 (2.5-inch) disk drive DAE. The letter X in the matrix indicates that there
is no 2U DAE available (supported) beyond that point. Note that the Total column in
Table 16 or Table 17 shows the total number of disks available (supported) using a
combination of the 2U DPE and the 2U DAE for that particular configuration.
