2.6 Disk Module Installation
CAUTION : Ensure that the disk modules are at room temperature before installing
and powering up the SS8460. It is recommended that the disks are
allowed at least two hours to acclimate to room temperature prior to
installation.
Figure 32 shows the layout of disks in the SS8460. The disk layout may also be found inside
the cover of the enclosure. Refer to Appendix B for information on zoning configuration.
When installing the disk modules:
- Create a more balanced load by evenly distributing the disk modules among the
enclosures
- Always fill the rows from front to back (also see Section 2.6.1 for blank module
requirement)
- Place the disks with similar rotational speeds in the same row
If a mixture of disk technologies will be populated into one enclosure, for optimal cooling,
the best loading order from front to back will be:
- SAS disks, SATA disks, then SSD
- 3.5" HDD, then 2.5" HDD or smaller
Observe all conventional ESD precautions when handling the disk
modules, avoid contact with module connectors. Electrostatic discharge
can damage the circuit boards.
