36 EMC VNXe3150 Hardware Information Guide
Overview
DPE and DAE configuration rules
Table 17 and Table 18 on page 37 provide a matrix describing what types and how many
DAEs can be used in either a dual VNXe3150 SP platform or in a single VNXe3150
platform.
As shown in each table, the first column shows either the number 12 ( Table 17 ), which
refers to the 2U, 12 (3.5-inch) disk drive DPE, or 25 ( Table 18 on page 37 ), which refers to
the 2U, 25 (2.5-inch) disk drive DPE used for that configuration. 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 17 or Table 18 on page 37 ), 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 DAE available beyond that point. Note
that the Total column in
Table 17 or Table 18 on page 37 shows the total number of disks
available using a combination of the DPE and the DAE for that particular configuration.
