Disk Shelf Allowable Configurations and Load Priority

The following are allowable configurations for additional DE3-24 disk shelf pairs:

• 20 SSD or HDD data drives and up to 4 SSD log or read cache devices

• 20 SSD or HDD data drives and 2 SSD log or read cache devices

• 24 SSD or HDD data drives

The placement of DE3-24 disk shelves follows this priority:

1. DE3-24 disk shelves with SSD log devices

2. DE3-24 disk shelves with SSD read cache devices

3. DE3-24 disk shelves without SSD log or read cache devices

In all cases, the placement of SSD log devices takes precedence over SSD read cache devices, and the placement is always in disk shelf pairs. SSD log and read cache devices can be installed into DE3-24 disk shelves in slots 20, 21, 22, and 23 in that order of priority.
